I'm posting this here as I believe this is more a pkgsrc/solaris ld issue...

as with gnome-gvs, curl also has a problem with builtin mit-krb5 on solaris.
With this patch, the libraries are setup as should be:
https://gist.github.com/risto3/6700163

but running a build, curl, which links to libcurl.so, doesn't seem to pull in libgss.so as referenced in libkrb5.so...

Seems I've seen this before, but what is solaris LDFLAG necessary to make sure pull indirects?

The following is with LD_OPTIONS="-zverbose -zguidance"

ld: fatal: symbol referencing errors. No output written to .libs/curl

Adding -zdirect and -zlazyload don't seem to offer any help, but if I hack '-lgss' after '-lkrb5' in src/Makefile the it builds just fine.

Is this because even though libkrb.so is linked with libgss.so, it also
has an additional RUNPATH?

I'd like to not have to special case solaris and pkgsrc vs builtin so I hope a simple LDFLAGS.SunOS might do the trick... any hints please?

I noticed in manpage gss_import_name (and in illumos-gate/usr/src/lib/libgss) that perhaps
-lgss should always be added when gssapi is expected for solaris mit-krb5.
In this case that safest bet is to change the patch line:

++                  gss_libs=`$GSSAPI_ROOT/bin/krb5-config --libs`

to

++                  gss_libs="`$GSSAPI_ROOT/bin/krb5-config --libs` -lgss"

which seems to work alright.

Base upon this, perhaps the same should happen in the gnome-vfs patch as well.

closing this as the above patch seems to be the appropriate interim solution, the gss symbols are in libgss.so and not libkrb5.so so the initial question is redeye out of the ballpark..

FITS (Flexible Image Transport System) is a data format most used in astronomy.
PyFITS is a Python module for reading, writing, and manipulating FITS files.
The module uses Python's object-oriented features to provide quick, easy, and
efficient access to FITS files. The use of Python's array syntax enables
immediate access to any FITS extension, header cards, or data items.

Changes to 2.4.0 (in py-pyfits):

Changelog
===========

3.2 (2013-11-26)
----------------

Highlights
^^^^^^^^^^

- Rewrote CFITSIO-based backend for handling tile compression of FITS files.
  It now uses a standard CFITSIO instead of heavily modified pieces of CFITSIO
  as before.  PyFITS ships with its own copy of CFITSIO v3.35 which supports
  the latest version of the Tiled Image Convention (v2.3), but system
  packagers may choose instead to strip this out in favor of a
  system-installed version of CFITSIO.  Earlier versions may work, but nothing
  earlier than 3.28 has been tested yet. (#169)

- Added support for reading and writing tables using the Q format for columns.
  The Q format is identical to the P format (variable-length arrays) except
  that it uses 64-bit integers for the data descriptors, allowing more than
  4 GB of variable-length array data in a single table. (#160)

- Added initial support for table columns containing pseudo-unsigned integers.
  This is currently enabled by using the ``uint=True`` option when opening
  files; any table columns with the correct BZERO value will be interpreted
  and returned as arrays of unsigned integers.

- Some refactoring of the table and ``FITS_rec`` modules in order to better
  separate the details of the FITS binary and ASCII table data structures from
  the HDU data structures that encapsulate them.  Most of these changes should
  not be apparent to users (but see API Changes below).


API Changes
^^^^^^^^^^^

- Assigning to values in ``ColDefs.names``, ``ColDefs.formats``,
  ``ColDefs.nulls`` and other attributes of ``ColDefs`` instances that return
  lists of column properties is no longer supported.  Assigning to those lists
  will no longer update the corresponding columns.  Instead, please just
  modify the ``Column`` instances directly (``Column.name``, ``Column.null``,
  etc.)

- The ``pyfits.new_table`` function is marked "pending deprecation".  This
  does not mean it will be removed outright or that its functionality has
  changed.  It will likely be replaced in the future for a function with
  similar, if not subtly different functionality.  A better, if not slightly
  more verbose approach is to use ``pyfits.FITS_rec.from_columns`` to create
  a new ``FITS_rec`` table--this has the same interface as
  ``pyfits.new_table``.  The difference is that it returns a plan ``FITS_rec``
  array, and not an HDU instance.  This ``FITS_rec`` object can then be used
  as the data argument in the constructors for ``BinTableHDU`` (for binary
  tables) or ``TableHDU`` (for ASCII tables).  This is analogous to creating
  an ``ImageHDU`` by passing in an image array.
  ``pyfits.FITS_rec.from_columns`` is just a simpler way of creating a
  FITS-compatible recarray from a FITS column specification.

- The ``updateHeader``, ``updateHeaderData``, and ``updateCompressedData``
  methods of the ``CompDataHDU`` class are pending deprecation and moved to
  internal methods.  The operation of these methods depended too much on
  internal state to be used safely by users; instead they are invoked
  automatically in the appropriate places when reading/writing compressed image
  HDUs.

- The ``CompDataHDU.compData`` attribute is pending deprecation in favor of
  the clearer and more PEP-8 compatible ``CompDataHDU.compressed_data``.

- The constructor for ``CompDataHDU`` has been changed to accept new keyword
  arguments.  The new keyword arguments are essentially the same, but are in
  underscore_separated format rather than camelCase format.  The old arguments
  are still pending deprecation.

- The internal attributes of HDU classes ``_hdrLoc``, ``_datLoc``, and
  ``_datSpan`` have been replaced with ``_header_offset``, ``_data_offset``,
  and ``_data_size`` respectively.  The old attribute names are still pending
  deprecation.  This should only be of interest to advanced users who have
  created their own HDU subclasses.

- The following previously deprecated functions and methods have been removed
  entirely: ``createCard``, ``createCardFromString``, ``upperKey``,
  ``ColDefs.data``, ``setExtensionNameCaseSensitive``, ``_File.getfile``,
  ``_TableBaseHDU.get_coldefs``, ``Header.has_key``, ``Header.ascardlist``.

  If you run your code with a previous version of PyFITS (>= 3.0, < 3.2) with
  the ``python -Wd`` argument, warnings for all deprecated interfaces still in
  use will be displayed.

- Interfaces that were pending deprecation are now fully deprecated.  These
  include: ``create_card``, ``create_card_from_string``, ``upper_key``,
  ``Header.get_history``, and ``Header.get_comment``.

- The ``.name`` attribute on HDUs is now directly tied to the HDU's header, so
  that if ``.header['EXTNAME']`` changes so does ``.name`` and vice-versa.

- The ``pyfits.file.PYTHON_MODES`` constant dict was renamed to
  ``pyfits.file.PYFITS_MODES`` which better reflects its purpose.  This is
  rarely used by client code, however.  Support for the old name will be
  removed by PyFITS 3.4.


Other Changes and Additions
^^^^^^^^^^^^^^^^^^^^^^^^^^^

- The new compression code also adds support for the ZQUANTIZ and ZDITHER0
  keywords added in more recent versions of this FITS Tile Compression spec.
  This includes support for lossless compression with GZIP. (#198) By default
  no dithering is used, but the ``SUBTRACTIVE_DITHER_1`` and
  ``SUBTRACTIVE_DITHER_2`` methods can be enabled by passing the correct
  constants to the ``quantize_method`` argument to the ``CompImageHDU``
  constuctor.  A seed can be manually specified, or automatically generated
  using either the system clock or checksum-based methods via the
  ``dither_seed`` argument.  See the documentation for ``CompImageHDU`` for
  more details. (#198) (spacetelescope/PYFITS#32)

- Images compressed with the Tile Compression standard can now be larger than
  4 GB through support of the Q format. (#159)

- All HDUs now have a ``.ver`` ``.level`` attribute that returns the value of
  the EXTVAL and EXTLEVEL keywords from that HDU's header, if the exist.  This
  was added for consistency with the ``.name`` attribute which returns the
  EXTNAME value from the header.

- Then ``Column`` and ``ColDefs`` classes have new ``.dtype`` attributes
  which give the Numpy dtype for the column data in the first case, and the
  full Numpy compound dtype for each table row in the latter case.

- There was an issue where new tables created defaulted the values in all
  string columns to '0.0'.  Now string columns are filled with empty strings
  by default--this seems a less surprising default, but it may cause
  differences with tables created with older versions of PyFITS.

- Improved round-tripping and preservation of manually assigned column
  attributes (``TNULLn``, ``TSCALn``, etc.) in table HDU headers.
  (astropy/astropy#996)


Bug Fixes
^^^^^^^^^

- Binary tables containing compressed images may, optionally, contain other
  columns unrelated to the tile compression convention. Although this is an
  uncommon use case, it is permitted by the standard. (#159)

- Reworked some of the file I/O routines to allow simpler, more consistent
  mapping between OS-level file modes ('rb', 'wb', 'ab', etc.) and the more
  "PyFITS-specific" modes used by PyFITS like "readonly" and "update".
  That is, if reading a FITS file from an open file object, it doesn't matter
  as much what "mode" it was opened in so long as it has the right
  capabilities (read/write/etc.)  Also works around bugs in the Python io
  module in 2.6+ with regard to file modes. (spacetelescope/PyFITS#33)

- Fixed an obscure issue that can occur on systems that don't have flush to
  memory-mapped files implemented (namely GNU Hurd). (astropy/astropy#968)


3.1.3 (2013-11-26)
------------------

- Disallowed assigning NaN and Inf floating point values as header values,
  since the FITS standard does not define a way to represent them in. Because
  this is undefined, the previous behavior did not make sense and produced
  invalid FITS files. (spacetelescope/PyFITS#11)

- Added a workaround for a bug in 64-bit OSX that could cause truncation when
  writing files greater than 2^32 bytes in size. (spacetelescope/PyFITS#28)

- Fixed a long-standing issue where writing binary tables did not correctly
  write the TFORMn keywords for variable-length array columns (they ommitted
  the max array length parameter of the format).  This was thought fixed in
  v3.1.2, but it was only fixed there for compressed image HDUs and not for
  binary tables in general.

- Fixed an obscure issue that can occur on systems that don't have flush to
  memory-mapped files implemented (namely GNU Hurd). (Backported from 3.2)


3.0.12 (2013-11-26)
-------------------

- Disallowed assigning NaN and Inf floating point values as header values,
  since the FITS standard does not define a way to represent them in. Because
  this is undefined, the previous behavior did not make sense and produced
  invalid FITS files. (Backported from 3.1.3)

- Added a workaround for a bug in 64-bit OSX that could cause truncation when
  writing files greater than 2^32 bytes in size. (Backported from 3.1.3)

- Fixed a long-standing issue where writing binary tables did not correctly
  write the TFORMn keywords for variable-length array columns (they ommitted

- Fixed an obscure issue that can occur on systems that don't have flush to
  memory-mapped files implemented (namely GNU Hurd). (Backported from 3.2)


3.1.2 (2013-04-22)
------------------

- When an error occurs opening a file in fitsdiff the exception message will
  now at least mention which file had the error. (#168)

- Fixed support for opening gzipped FITS files by filename in a writeable mode
  (PyFITS has supported writing to gzip files for some time now, but only
  enabled it when GzipFile objects were passed to ``pyfits.open()`` due to
  some legacy code preventing full gzip support. (#195)

- Added a more helpful error message in the case of malformatted FITS files
  that contain non-float NULL values in an ASCII table but are missing the
  required TNULLn keywords in the header. (#197)

- Fixed an (apparently long-standing) issue where writing compressed images
  did not correctly write the TFORMn keywords for variable-length array
  columns (they ommitted the max array length parameter of the format). (#199)

- Slightly refactored how tables containing variable-length array columns are
  handled to add two improvements: Fixes an issue where accessing the data
  after a call to the `pyfits.getdata` convenience function caused an
  exception, and allows the VLA data to be read from an existing mmap of the
  FITS file. (#200)

- Fixed a bug that could occur when opening a table containing
  multi-dimensional columns (i.e. via the TDIMn keyword) and then writing it
  out to a new file. (#201)

- Added use of the console_scripts entry point to install the fitsdiff and
  fitscheck scripts, which if nothing else provides better Windows support.
  The generated scripts now override the ones explicitly defined in the
  scripts/ directory (which were just trivial stubs to begin with). (#202)

- Fixed a bug on Python 3 where attempting to open a non-existent file on
  Python 3 caused a seemingly unrelated traceback. (#203)

- Fixed a bug in fitsdiff that reported two header keywords containing NaN
  as value as different. (#204)

- Fixed an issue in the tests that caused some tests to fail if pyfits is
  installed with read-only permissions. (#208)

- Fixed a bug where instantiating a ``BinTableHDU`` from a numpy array
  containing boolean fields converted all the values to ``False``. (#215)

- Fixed an issue where passing an array of integers into the constructor of
  ``Column()`` when the column type is floats of the same byte width caused the
  column array to become garbled. (#218)

- Fixed inconsistent behavior in creating CONTINUE cards from byte strings
  versus unicode strings in Python 2--CONTINUE cards can now be created
  properly from unicode strings (so long as they are convertable to ASCII).
  (spacetelescope/PyFITS#1)

- Fixed a couple cases where creating a new table using TDIMn in some of the
  columns could caused a crash. (spacetelescope/PyFITS#3)

- Fixed a bug in parsing HIERARCH keywords that do not have a space after
  the first equals sign (before the value). (spacetelescope/PyFITS#5)

- Prevented extra leading whitespace on HIERARCH keywords from being treated
  as part of the keyword. (spacetelescope/PyFITS#6)

- Fixed a bug where HIERARCH keywords containing lower-case letters was
  mistakenly marked as invalid during header validation.
  (spacetelescope/PyFITS#7)

- Fixed an issue that was ancillary to (spacetelescope/PyFITS#7) where the
  ``Header.index()`` method did not work correctly with HIERARCH keywords
  containing lower-case letters.


3.0.11 (2013-04-17)
-------------------

- Fixed support for opening gzipped FITS files by filename in a writeable mode
  (PyFITS has supported writing to gzip files for some time now, but only
  enabled it when GzipFile objects were passed to ``pyfits.open()`` due to
  some legacy code preventing full gzip support. Backported from 3.1.2. (#195)

  columns could caused a crash. Backported from 3.1.2.
  (spacetelescope/PyFITS#3)


3.1.1 (2013-01-02)
------------------

This is a bug fix release for the 3.1.x series.

Bug Fixes
^^^^^^^^^

- Improved handling of scaled images and pseudo-unsigned integer images in
  compressed image HDUs.  They now work more transparently like normal image
  HDUs with support for the ``do_not_scale_image_data`` and ``uint`` options,
  as well as ``scale_back`` and ``save_backup``.  The ``.scale()`` method
  works better too. (#88)

- Permits non-string values for the EXTNAME keyword when reading in a file,
  rather than throwing an exception due to the malformatting.  Added
  verification for the format of the EXTNAME keyword when writing. (#96)

- Added support for EXTNAME and EXTVER in PRIMARY HDUs.  That is, if EXTNAME
  is specified in the header, it will also be reflected in the ``.name``
  attribute and in ``pyfits.info()``.  These keywords used to be verboten in
  PRIMARY HDUs, but the latest version of the FITS standard allows them.
  (#151)

- HCOMPRESS can again be used to compress data cubes (and higher-dimensional
  arrays) so long as the tile size is effectively 2-dimensional. In fact,
  PyFITS will automatically use compatible tile sizes even if they're not
  explicitly specified. (#171)

- Added support for the optional ``endcard`` parameter in the
  ``Header.fromtextfile()`` and ``Header.totextfile()`` methods.  Although
  ``endcard=False`` was a reasonable default assumption, there are still text
  dumps of FITS headers that include the END card, so this should have been
  more flexible. (#176)

- Fixed a crash when running fitsdiff on two empty (that is, zero row) tables.
  (#178)

- Fixed an issue where opening files containing random groups HDUs in update
  mode could cause an unnecessary rewrite of the file even if none of the
  data is modified. (#179)

- Fixed a bug that could caused a deadlock in the filesystem on OSX if PyFITS
  is used with Numpy 1.7 in some cases. (#180)

- Fixed a crash when generating diff reports from diffs using the
  ``ignore_comments`` options. (#181)

- Fixed some bugs with WCS Paper IV record-valued keyword cards:

  - Cards that looked kind of like RVKCs but were not intended to be were
    over-permissively treated as such--commentary keywords like COMMENT and
    HISTORY were particularly affected. (#183)

  - Looking up a card in a header by its standard FITS keyword only should
    always return the raw value of that card.  That way cards containing
    values that happen to valid RVKCs but were not intended to be will still
    be treated like normal cards. (#184)

  - Looking up a RVKC in a header with only part of the field-specifier (for
    example "DP1.AXIS" instead of "DP1.AXIS.1") was implicitly treated as a
    wildcard lookup. (#184)

- Fixed a crash when diffing two FITS files where at least one contains a
  compressed image HDU which was not recognized as an image instead of a
  table. (#187)

- Fixed bugs in the backwards compatibility layer for the ``CardList.index``
  and ``CardList.count`` methods. (#190)

- Improved ``__repr__`` and text file representation of cards with long values
  that are split into CONTINUE cards. (#193)

- Fixed a crash when trying to assign a long (> 72 character) value to blank
  ('') keywords. This also changed how blank keywords are represented--there
  are still exactly 8 spaces before any commentary content can begin; this
  *may* affect the exact display of header cards that assumed there could be
  fewer spaces in a blank keyword card before the content begins. However, the
  current approach is more in line with the requirements of the FITS standard.
  (#194)


3.0.10 (2013-01-02)
-------------------

- Improved handling of scaled images and pseudo-unsigned integer images in
  compressed image HDUs.  They now work more transparently like normal image
  HDUs with support for the ``do_not_scale_image_data`` and ``uint`` options,
  as well as ``scale_back`` and ``save_backup``.  The ``.scale()`` method
  works better too.  Backported from 3.1.1. (#88)

- Permits non-string values for the EXTNAME keyword when reading in a file,
  rather than throwing an exception due to the malformatting.  Added
  verification for the format of the EXTNAME keyword when writing.  Backported
  from 3.1.1. (#96)

- Added support for EXTNAME and EXTVER in PRIMARY HDUs.  That is, if EXTNAME
  is specified in the header, it will also be reflected in the ``.name``
  attribute and in ``pyfits.info()``.  These keywords used to be verbotten in
  PRIMARY HDUs, but the latest version of the FITS standard allows them.
  Backported from 3.1.1. (#151)

- HCOMPRESS can again be used to compress data cubes (and higher-dimensional
  arrays) so long as the tile size is effectively 2-dimensional. In fact,
  PyFITS will not automatically use compatible tile sizes even if they're not
  explicitly specified.  Backported from 3.1.1. (#171)

- Fixed a bug when writing out files containing zero-width table columns,
  where the TFIELDS keyword would be updated incorrectly, leaving the table
  largely unreadable.  Backported from 3.1.0. (#174)

- Fixed an issue where opening files containing random groups HDUs in update
  mode could cause an unnecessary rewrite of the file even if none of the
  data is modified.  Backported from 3.1.1. (#179)

- Fixed a bug that could caused a deadlock in the filesystem on OSX if PyFITS
  is used with Numpy 1.7 in some cases. Backported from 3.1.1. (#180)


3.1 (2012-08-08)
----------------

Highlights
^^^^^^^^^^

- The ``Header`` object has been significantly reworked, and ``CardList``
  objects are now deprecated (their functionality folded into the ``Header``
  class).  See API Changes below for more details.

- Memory maps are now used by default to access HDU data.  See API Changes
  below for more details.

- Now includes a new version of the ``fitsdiff`` program for comparing two
  FITS files, and a new FITS comparison API used by ``fitsdiff``.  See New
  Features below.

API Changes
^^^^^^^^^^^

- The ``Header`` class has been rewritten, and the ``CardList`` class is
  deprecated.  Most of the basic details of working with FITS headers are
  unchanged, and will not be noticed by most users.  But there are differences
  in some areas that will be of interest to advanced users, and to application
  developers.  For full details of the changes, see the "Header Interface
  Transition Guide" section in the PyFITS documentation.  See ticket #64 on
  the PyFITS Trac for futher details and background. Some highlights are
  listed below:

  * The Header class now fully implements the Python dict interface, and can
    be used interchangably with a dict, where the keys are header keywords.

  * New keywords can be added to the header using normal keyword assignment
    (previously it was necessary to use ``Header.update`` to add new
    keywords).  For example::

        >>> header['NAXIS'] = 2

    will update the existing 'FOO' keyword if it already exists, or add a new
    one if it doesn't exist, just like a dict.

  * It is possible to assign both a value and a comment at the same time using
    a tuple::

        >>> header['NAXIS'] = (2, 'Number of axes')

  * To add/update a new card and ensure it's added in a specific location, use
    ``Header.set()``::

        >>> header.set('NAXIS', 2, 'Number of axes', after='BITPIX')

    This works the same as the old ``Header.update()``.  ``Header.update()``
    still works in the old way too, but is deprecated.

  * Although ``Card`` objects still exist, it generally is not necessary to
    work with them directly.  ``Header.ascardlist()``/``Header.ascard`` are
    deprecated and should not be used.  To directly access the ``Card``
    objects in a header, use ``Header.cards``.

  * To access card comments, it is still possible to either go through the
    card itself, or through ``Header.comments``.  For example::

       >>> header.cards['NAXIS'].comment
       Number of axes
       >>> header.comments['NAXIS']
       Number of axes

  * ``Card`` objects can now be used interchangeably with
    ``(keyword, value, comment)`` 3-tuples.  They still have ``.value`` and
    ``.comment`` attributes as well.  The ``.key`` attribute has been renamed
    to ``.keyword`` for consistency, though ``.key`` is still supported (but
    deprecated).

- Memory mapping is now used by default to access HDU data.  That is,
  ``pyfits.open()`` uses ``memmap=True`` as the default.  This provides better
  performance in the majority of use cases--there are only some I/O intensive
  applications where it might not be desirable.  Enabling mmap by default also
  enabled finding and fixing a large number of bugs in PyFITS' handling of
  memory-mapped data (most of these bug fixes were backported to PyFITS
  3.0.5). (#85)

  * A new ``pyfits.USE_MEMMAP`` global variable was added.  Set
    ``pyfits.USE_MEMMAP = False`` to change the default memmap setting for
    opening files.  This is especially useful for controlling the behavior in
    applications where pyfits is deeply embedded.

  * Likewise, a new ``PYFITS_USE_MEMMAP`` environment variable is supported.
    Set ``PYFITS_USE_MEMMAP = 0`` in your environment to change the default
    behavior.

- The ``size()`` method on HDU objects is now a ``.size`` property--this
  returns the size in bytes of the data portion of the HDU, and in most cases
  is equivalent to ``hdu.data.nbytes`` (#83)

- ``BinTableHDU.tdump`` and ``BinTableHDU.tcreate`` are deprecated--use
  ``BinTableHDU.dump`` and ``BinTableHDU.load`` instead.  The new methods
  output the table data in a slightly different format from previous versions,
  which places quotes around each value.  This format is compatible with data
  dumps from previous versions of PyFITS, but not vice-versa due to a parsing
  bug in older versions.

- Likewise the ``pyfits.tdump`` and ``pyfits.tcreate`` convenience function
  versions of these methods have been renamed ``pyfits.tabledump`` and
  ``pyfits.tableload``.  The old deprecated, but currently retained for
  backwards compatibility. (r1125)

- A new global variable ``pyfits.EXTENSION_NAME_CASE_SENSITIVE`` was added.
  This serves as a replacement for ``pyfits.setExtensionNameCaseSensitive``
  which is not deprecated and may be removed in a future version.  To enable
  case-sensitivity of extension names (i.e. treat 'sci' as distict from 'SCI')
  set ``pyfits.EXTENSION_NAME_CASE_SENSITIVE = True``.  The default is
  ``False``. (r1139)

- A new global configuration variable ``pyfits.STRIP_HEADER_WHITESPACE`` was
  added.  By default, if a string value in a header contains trailing
  whitespace, that whitespace is automatically removed when the value is read.
  Now if you set ``pyfits.STRIP_HEADER_WHITESPACE = False`` all whitespace is
  preserved. (#146)

- The old ``classExtensions`` extension mechanism (which was deprecated in
  PyFITS 3.0) is removed outright.  To our knowledge it was no longer used
  anywhere. (r1309)

- Warning messages from PyFITS issued through the Python warnings API are now
  output to stderr instead of stdout, as is the default.  PyFITS no longer
  modifies the default behavior of the warnings module with respect to which
  stream it outputs to. (r1319)

- The ``checksum`` argument to ``pyfits.open()`` now accepts a value of
  'remove', which causes any existing CHECKSUM/DATASUM keywords to be ignored,
  and removed when the file is saved.

New Features
^^^^^^^^^^^^

- Added support for the proposed "FITS" extension HDU type.  See
  http://listmgr.cv.nrao.edu/pipermail/fitsbits/2002-April/001094.html.  FITS
  HDUs contain an entire FITS file embedded in their data section.  `FitsHDU`
  objects work like other HDU types in PyFITS.  Their ``.data`` attribute
  returns the raw data array.  However, they have a special ``.hdulist``
  attribute which processes the data as a FITS file and returns it as an
  in-memory HDUList object.  FitsHDU objects also support a
  ``FitsHDU.fromhdulist()`` classmethod which returns a new `FitsHDU` object
  that embeds the supplied HDUList. (#80)

- Added a new ``.is_image`` attribute on HDU objects, which is True if the HDU
  data is an 'image' as opposed to a table or something else.  Here the
  meaning of 'image' is fairly loose, and mostly just means a Primary or Image
  extension HDU, or possibly a compressed image HDU (#71)

- Added an ``HDUList.fromstring`` classmethod which can parse a FITS file
  already in memory and instantiate and ``HDUList`` object from it.  This
  could be useful for integrating PyFITS with other libraries that work on
  FITS file, such as CFITSIO.  It may also be useful in streaming
  applications.  The name is a slight misnomer, in that it actually accepts
  any Python object that implements the buffer interface, which includes
  ``bytes``, ``bytearray``, ``memoryview``, ``numpy.ndarray``, etc. (#90)

- Added a new ``pyfits.diff`` module which contains facilities for comparing
  FITS files.  One can use the ``pyfits.diff.FITSDiff`` class to compare two
  FITS files in their entirety.  There is also a ``pyfits.diff.HeaderDiff``
  class for just comparing two FITS headers, and other similar interfaces.
  See the PyFITS Documentation for more details on this interface.  The
  ``pyfits.diff`` module powers the new ``fitsdiff`` program installed with
  PyFITS.  After installing PyFITS, run ``fitsdiff --help`` for usage details.

- ``pyfits.open()`` now accepts a ``scale_back`` argument.  If set to
  ``True``, this automatically scales the data using the original BZERO and
  BSCALE parameters the file had when it was first opened, if any, as well as
  the original BITPIX.  For example, if the original BITPIX were 16, this
  would be equivalent to calling ``hdu.scale('int16', 'old')`` just before
  calling ``flush()`` or ``close()`` on the file.  This option applies to all
  HDUs in the file. (#120)

- ``pyfits.open()`` now accepts a ``save_backup`` argument.  If set to
  ``True``, this automatically saves a backup of the original file before
  flushing any changes to it (this of course only applies to update and append
  mode).  This may be especially useful when working with scaled image data.
  (#121)

Changes in Behavior
^^^^^^^^^^^^^^^^^^^

- Warnings from PyFITS are not output to stderr by default, instead of stdout
  as it has been for some time.  This is contrary to most users' expectations
  and makes it more difficult for them to separate output from PyFITS from the
  desired output for their scripts. (r1319)

Bug Fixes
^^^^^^^^^

- Fixed ``pyfits.tcreate()`` (now ``pyfits.tableload()``) to be more robust
  when encountering blank lines in a column definition file (#14)

- Fixed a fairly rare crash that could occur in the handling of CONTINUE cards
  when using Numpy 1.4 or lower (though 1.4 is the oldest version supported by
  PyFITS). (r1330)

- Fixed ``_BaseHDU.fromstring`` to actually correctly instantiate an HDU
  object from a string/buffer containing the header and data of that HDU.
  This allowed for the implementation of ``HDUList.fromstring`` described
  above. (#90)

- Fixed a rare corner case where, in some use cases, (mildly, recoverably)
  malformatted float values in headers were not properly returned as floats.
  (#137)

- Fixed a corollary to the previous bug where float values with a leading zero
  before the decimal point had the leading zero unnecessarily removed when
  saving changes to the file (eg. "0.001" would be written back as ".001" even
  if no changes were otherwise made to the file). (#137)

- When opening a file containing CHECKSUM and/or DATASUM keywords in update
  mode, the CHECKSUM/DATASUM are updated and preserved even if the file was
  opened with checksum=False.  This change in behavior prevents checksums from
  being unintentionally removed. (#148)

- Fixed a bug where ``ImageHDU.scale(option='old')`` wasn't working at all--it
  was not restoring the image to its original BSCALE and BZERO values. (#162)

- Fixed a bug when writing out files containing zero-width table columns,
  where the TFIELDS keyword would be updated incorrectly, leaving the table
  largely unreadable.  This fix will be backported to the 3.0.x series in
  version 3.0.10.  (#174)


3.0.9 (2012-08-06)
------------------

This is a bug fix release for the 3.0.x series.

Bug Fixes
^^^^^^^^^

- Fixed ``Header.values()``/``Header.itervalues()`` and ``Header.items()``/
  ``Header.iteritems()`` to correctly return the different values for
  duplicate keywords (particularly commentary keywords like HISTORY and
  COMMENT).  This makes the old Header implementation slightly more compatible
  with the new implementation in PyFITS 3.1. (#127)

  .. note::
      This fix did not change the existing behavior from earlier PyFITS
      versions where ``Header.keys()`` returns all keywords in the header with
      duplicates removed.  PyFITS 3.1 changes that behavior, so that
      ``Header.keys()`` includes duplicates.

- Fixed a bug where ``ImageHDU.scale(option='old')`` wasn't working at all--it
  was not restoring the image to its original BSCALE and BZERO values. (#162)

- Fixed a bug where opening a file containing compressed image HDUs in
  'update' mode and then immediately closing it without making any changes
  caused the file to be rewritten unncessarily. (#167)

- Fixed two memory leaks that could occur when writing compressed image data,
  or in some cases when opening files containing compressed image HDUs in
  'update' mode. (#168)


3.0.8 (2012-06-04)
------------------

Changes in Behavior
^^^^^^^^^^^^^^^^^^^

- Prior to this release, image data sections did not work with scaled
  data--that is, images with non-trivial BSCALE and/or BZERO values.
  Previously, in order to read such images in sections, it was necessary to
  manually apply the BSCALE+BZERO to each section.  It's worth noting that
  sections *did* support pseudo-unsigned ints (flakily).  This change just
  extends that support for general BSCALE+BZERO values.

Bug Fixes
^^^^^^^^^

- Fixed a bug that prevented updates to values in boolean table columns from
  being saved.  This turned out to be a symptom of a deeper problem that could
  prevent other table updates from being saved as well. (#139)

- Fixed a corner case in which a keyword comment ending with the string "END"
  could, in some circumstances, cause headers (and the rest of the file after
  that point) to be misread. (#142)

- Fixed support for scaled image data and psuedo-unsigned ints in image data
  sections (``hdu.section``).  Previously this was not supported at all.  At
  some point support was supposedly added, but it was buggy and incomplete.
  Now the feature seems to work much better. (#143)

- Fixed the documentation to point out that image data sections *do* support
  non-contiguous slices (and have for a long time).  The documentation was
  never updated to reflect this, and misinformed users that only contiguous
  slices were supported, leading to some confusion. (#144)

- Fixed a bug where creating an ``HDUList`` object containing multiple PRIMARY
  HDUs caused an infinite recursion when validating the object prior to
  writing to a file. (#145)

- Fixed a rare but serious case where saving an update to a file that
  previously had a CHECKSUM and/or DATASUM keyword, but removed the checksum
  in saving, could cause the file to be slightly corrupted and unreadable.
  (#147)

- Fixed problems with reading "non-standard" FITS files with primary headers
  containing SIMPLE = F.  PyFITS has never made many guarantees as to how such
  files are handled.  But it should at least be possible to read their
  headers, and the data if possible.  Saving changes to such a file should not
  try to prepend an unwanted valid PRIMARY HDU. (#157)

- Fixed a bug where opening an image with ``disable_image_compression = True``
  caused compression to be disabled for all subsequent ``pyfits.open()`` calls.
  (r1651)


3.0.7 (2012-04-10)
------------------

Changes in Behavior
^^^^^^^^^^^^^^^^^^^

- Slices of GroupData objects now return new GroupData objects instead of
  extended multi-row _Group objects. This is analogous to how PyFITS 3.0 fixed
  FITS_rec slicing, and should have been fixed for GroupData at the same time.
  The old behavior caused bugs where functions internal to Numpy expected that
  slicing an ndarray would return a new ndarray.  As this is a rare usecase
  with a rare feature most users are unlikely to be affected by this change.

- The previously internal _Group object for representing individual group
  records in a GroupData object are renamed Group and are now a public
  interface.  However, there's almost no good reason to create Group objects
  directly, so it shouldn't be considered a "new feature".

- An annoyance from PyFITS 3.0.6 was fixed, where the value of the EXTEND
  keyword was always being set to F if there are not actually any extension
  HDUs.  It was unnecessary to modify this value.

Bug Fixes
^^^^^^^^^

- Fixed GroupData objects to return new GroupData objects when sliced instead
  of _Group record objects.  See "Changes in behavior" above for more details.

- Fixed slicing of Group objects--previously it was not possible to slice
  slice them at all.

- Made it possible to assign `np.bool_` objects as header values. (#123)

- Fixed overly strict handling of the EXTEND keyword; see "Changes in
  behavior" above. (#124)

- Fixed many cases where an HDU's header would be marked as "modified" by
  PyFITS and rewritten, even when no changes to the header are necessary.
  (#125)

- Fixed a bug where the values of the PTYPEn keywords in a random groups HDU
  were forced to be all lower-case when saving the file. (#130)

- Removed an unnecessary inline import in `ExtensionHDU.__setattr__` that was
  causing some slowdown when opening files containing a large number of
  extensions, plus a few other small (but not insignficant) performance
  improvements thanks to Julian Taylor. (#133)

- Fixed a regression where header blocks containing invalid end-of-header
  padding (i.e. null bytes instead of spaces) couldn't be parsed by PyFITS.
  Such headers can be parsed again, but a warning is raised, as such headers
  are not valid FITS. (#136)

- Fixed a memory leak where table data in random groups HDUs weren't being
  garbage collected. (#138)


3.0.6 (2012-02-29)
------------------

Highlights
^^^^^^^^^^

The main reason for this release is to fix an issue that was introduced in
PyFITS 3.0.5 where merely opening a file containing scaled data (that is, with
non-trivial BSCALE and BZERO keywords) in 'update' mode would cause the data
to be automatically rescaled--possibly converting the data from ints to
floats--as soon as the file is closed, even if the application did not touch
the data.  Now PyFITS will only rescale the data in an extension when the data
is actually accessed by the application.  So opening a file in 'update' mode
in order to modify the header or append new extensions will not cause any
change to the data in existing extensions.

This release also fixes a few Windows-specific bugs found through more
extensive Windows testing, and other miscellaneous bugs.

Bug Fixes
^^^^^^^^^

- More accurate error messages when opening files containing invalid header
  cards. (#109)

- Fixed a possible reference cycle/memory leak that was caught through more
  extensive testing on Windows. (#112)

- Fixed 'ostream' mode to open the underlying file in 'wb' mode instead of 'w'
  mode. (#112)

- Fixed a Windows-only issue where trying to save updates to a resized FITS
  file could result in a crash due to there being open mmaps on that file.
  (#112)

- Fixed a crash when trying to create a FITS table (i.e. with new_table())
  from a Numpy array containing bool fields. (#113)

- Fixed a bug where manually initializing an ``HDUList`` with a list of of
  HDUs wouldn't set the correct EXTEND keyword value on the primary HDU.
  (#114)

- Fixed a crash that could occur when trying to deepcopy a Header in Python <
  2.7. (#115)

- Fixed an issue where merely opening a scaled image in 'update' mode would
  cause the data to be converted to floats when the file is closed. (#119)


3.0.5 (2012-01-30)
------------------

- Fixed a crash that could occur when accessing image sections of files
  opened with memmap=True. (r1211)

- Fixed the inconsistency in the behavior of files opened in 'readonly' mode
  when memmap=True vs. when memmap=False.  In the latter case, although
  changes to array data were not saved to disk, it was possible to update the
  array data in memory.  On the other hand with memmap=True, 'readonly' mode
  prevented even in-memory modification to the data.  This is what
  'copyonwrite' mode was for, but difference in behavior was confusing.  Now
  'readonly' is equivalent to 'copyonwrite' when using memmap.  If the old
  behavior of denying changes to the array data is necessary, a new
  'denywrite' mode may be used, though it is only applicable to files opened
  with memmap. (r1275)

- Fixed an issue where files opened with memmap=True would return image data
  as a raw numpy.memmap object, which can cause some unexpected
  behaviors--instead memmap object is viewed as a numpy.ndarray. (r1285)

- Fixed an issue in Python 3 where a workaround for a bug in Numpy on Python 3
  interacted badly with some other software, namely to vo.table package (and
  possibly others). (r1320, r1337, and #110)

- Fixed buggy behavior in the handling of SIGINTs (i.e. Ctrl-C keyboard
  interrupts) while flushing changes to a FITS file.  PyFITS already prevented
  SIGINTs from causing an incomplete flush, but did not clean up the signal
  handlers properly afterwards, or reraise the keyboard interrupt once the
  flush was complete. (r1321)

- Fixed a crash that could occur in Python 3 when opening files with checksum
  checking enabled. (r1336)

- Fixed a small bug that could cause a crash in the `StreamingHDU` interface
  when using Numpy below version 1.5.

- Fixed a crash that could occur when creating a new `CompImageHDU` from an
  array of big-endian data. (#104)

- Fixed a crash when opening a file with extra zero padding at the end.
  Though FITS files should not have such padding, it's not explictly forbidden
  by the format either, and PyFITS shouldn't stumble over it. (#106)

- Fixed a major slowdown in opening tables containing large columns of string
  values.  (#111)


3.0.4 (2011-11-22)
------------------

- Fixed a crash when writing HCOMPRESS compressed images that could happen on
  Python 2.5 and 2.6. (r1217)

- Fixed a crash when slicing an table in a file opened in 'readonly' mode with
  memmap=True. (r1230)

- Writing changes to a file or writing to a new file verifies the output in
  'fix' mode by default instead of 'exception'--that is, PyFITS will
  automatically fix common FITS format errors rather than raising an
  exception. (r1243)

- Fixed a bug where convenience functions such as getval() and getheader()
  crashed when specifying just 'PRIMARY' as the extension to use (r1263).

- Fixed a bug that prevented passing keyword arguments (beyond the standard
  data and header arguments) as positional arguments to the constructors of
  extension HDU classes.

- Fixed some tests that were failing on Windows--in this case the tests
  themselves failed to close some temp files and Windows refused to delete them
  while there were still open handles on them. (r1295)

- Fixed an issue with floating point formatting in header values on Python 2.5
  for Windows (and possibly other platforms).  The exponent was zero-padded to
  3 digits; although the FITS standard makes no specification on this, the
  formatting is now normalized to always pad the exponent to two digits.
  (r1295)

- Fixed a bug where long commentary cards (such as HISTORY and COMMENT) were
  broken into multiple CONTINUE cards.  However, commentary cards are not
  expected to be found in CONTINUE cards.  Instead these long cards are broken
  into multiple commentary cards. (#97)

- GZIP/ZIP-compressed FITS files can be detected and opened regardless of
  their filename extension. (#99)

- Fixed a serious bug where opening scaled images in 'update' mode and then
  closing the file without touching the data would cause the file to be
  corrupted. (#101)


3.0.3 (2011-10-05)
------------------

- Fixed several small bugs involving corner cases in record-valued keyword
  cards (#70)

- In some cases HDU creation failed if the first keyword value in the header
  was not a string value (#89)

- Fixed a crash when trying to compute the HDU checksum when the data array
  contains an odd number of bytes (#91)

- Disabled an unnecessary warning that was displayed on opening compressed
  HDUs with disable_image_compression = True (#92)

- Fixed a typo in code for handling HCOMPRESS compressed images.


3.0.2 (2011-09-23)
------------------

- The ``BinTableHDU.tcreate`` method and by extension the ``pyfits.tcreate``
  function don't get tripped up by blank lines anymore (#14)

- The presence, value, and position of the EXTEND keyword in Primary HDUs is
  verified when reading/writing a FITS file (#32)

- Improved documentation (in warning messages as well as in the handbook) that
  PyFITS uses zero-based indexing (as one would expect for C/Python code, but
  contrary to the PyFITS standard which was written with FORTRAN in mind)
  (#68)

- Fixed a bug where updating a header card comment could cause the value to be
  lost if it had not already been read from the card image string.

- Fixed a related bug where changes made directly to Card object in a header
  (i.e. assigning directly to card.value or card.comment) would not propagate
  when flushing changes to the file (#69) [Note: This and the bug above it
  were originally reported as being fixed in version 3.0.1, but the fix was
  never included in the release.]

- Improved file handling, particularly in Python 3 which had a few small file
  I/O-related bugs (#76)

- Fixed a bug where updating a FITS file would sometimes cause it to lose its
  original file permissions (#79)

- Fixed the handling of TDIMn keywords; 3.0 added support for them, but got
  the axis order backards (they were treated as though they were row-major)
  (#82)

- Fixed a crash when a FITS file containing scaled data is opened and
  immediately written to a new file without explicitly viewing the data first
  (#84)

- Fixed a bug where creating a table with columns named either 'names' or
  'formats' resulted in an infinite recursion (#86)


3.0.1 (2011-09-12)
------------------

- Fixed a bug where updating a header card comment could cause the value to be
  lost if it had not already been read from the card image string.

- Changed ``_TableBaseHDU.data`` so that if the data contain an empty table a
  ``FITS_rec`` object with zero rows is returned rather than ``None``.

- The ``.key`` attribute of ``RecordValuedKeywordCards`` now returns the full
  keyword+field-specifier value, instead of just the plain keyword (#46)

- Fixed a related bug where changes made directly to Card object in a header
  (i.e. assigning directly to card.value or card.comment) would not propagate
  when flushing changes to the file (#69)

- Fixed a bug where writing a table with zero rows could fail in some cases
  (#72)

- Miscellanous small bug fixes that were causing some tests to fail,
  particularly on Python 3 (#74, #75)

- Fixed a bug where creating a table column from an array in non-native byte
  order would not preserve the byte order, thus interpreting the column array
  using the wrong byte order (#77)


3.0.0 (2011-08-23)
--------------------

- Contains major changes, bumping the version to 3.0

- Large amounts of refactoring and reorganization of the code; tried to
  preserve public API backwards-compatibility with older versions (private API
  has many changes and is not guaranteed to be backwards-compatible).  There
  are a few small public API changes to be aware of:

  * The pyfits.rec module has been removed completely.  If your version of
    numpy does not have the numpy.core.records module it is too old to be used
    with PyFITS.

  * The ``Header.ascardlist()`` method is deprecated--use the ``.ascard``
    attribute instead.

  * ``Card`` instances have a new ``.cardimage`` attribute that should be used
    rather than ``.ascardimage()``, which may become deprecated.

  * The ``Card.fromstring()`` method is now a classmethod.  It returns a new
    ``Card`` instance rather than modifying an existing instance.

  * The ``req_cards()`` method on HDU instances has changed:  The ``pos``
    argument is not longer a string.  It is either an integer value (meaning
    the card's position must match that value) or it can be a function that
    takes the card's position as it's argument, and returns True if the
    position is valid.  Likewise, the ``test`` argument no longer takes a
    string, but instead a function that validates the card's value and returns
    True or False.

  * The ``get_coldefs()`` method of table HDUs is deprecated.  Use the
    ``.columns`` attribute instead.

  * The ``ColDefs.data`` attribute is deprecated--use ``ColDefs.columns``
    instead (though in general you shouldn't mess with it directly--it might
    become internal at some point).

  * ``FITS_record`` objects take ``start`` and ``end`` as arguments instead of
    ``startColumn`` and ``endColumn`` (these are rarely created manually, so
    it's unlikely that this change will affect anyone).

  * ``BinTableHDU.tcreate()`` is now a classmethod, and returns a new
    ``BinTableHDU`` instance.

  * Use ``ExtensionHDU`` and ``NonstandardExtHDU`` for making new extension HDU
    classes.  They are now public interfaces, wheres previously they were
    private and prefixed with underscores.

  * Possibly others--please report if you find any changes that cause
    difficulties.

- Calls to deprecated functions will display a Deprecation warning.  However,
  in Python 2.7 and up Deprecation warnings are ignored by default, so run
  Python with the `-Wd` option to see if you're using any deprecated
  functions.  If we get close to actually removing any functions, we might
  make the Deprecation warnings display by default.

- Added basic Python 3 support

- Added support for multi-dimensional columns in tables as specified by the
  TDIMn keywords (#47)

- Fixed a major memory leak that occurred when creating new tables with the
  ``new_table()`` function (#49)
  be padded with zero-bytes) vs ASCII tables (where strings are padded with
  spaces) (#15)

- Fixed a bug in which the case of Random Access Group parameters names was not
  preserved when writing (#41)

- Added support for binary table fields with zero width (#42)

- Added support for wider integer types in ASCII tables; although this is non-
  standard, some GEIS images require it (#45)

- Fixed a bug that caused the index_of() method of HDULists to crash when the
  HDUList object is created from scratch (#48)

- Fixed the behavior of string padding in binary tables (where strings should
  be padded with nulls instead of spaces)

- Fixed a rare issue that caused excessive memory usage when computing
  checksums using a non-standard block size (see r818)

- Add support for forced uint data in image sections (#53)

- Fixed an issue where variable-length array columns were not extended when
  creating a new table with more rows than the original (#54)

- Fixed tuple and list-based indexing of FITS_rec objects (#55)

- Fixed an issue where BZERO and BSCALE keywords were appended to headers in
  the wrong location (#56)

- ``FITS_record`` objects (table rows) have full slicing support, including
  stepping, etc. (#59)

- Fixed a bug where updating multiple files simultaneously (such as when
  running parallel processes) could lead to a race condition with mktemp()
  (#61)

- Fixed a bug where compressed image headers were not in the order expected by
  the funpack utility (#62)

Changes from 2.2.1 to 2.2.2
===========================

* The `copy_args` argument of `NumExpr` function has been brought
  back.  This has been mainly necessary for compatibility with
  PyTables < 3.0, which I decided to continue to support.  Fixed #115.

* The `__nonzero__` method in `ExpressionNode` class has been
  commented out.  This is also for compatibility with PyTables < 3.0.
  See #24 for details.

* Fixed the type of some parameters in the C extension so that s390
  architecture compiles.  Fixes #116.  Thank to Antonio Valentino for
  reporting and the patch.


Changes from 2.2 to 2.2.1
=========================

* Fixes a secondary effect of "from numpy.testing import `*`", where
  division is imported now too, so only then necessary functions from
  there are imported now.  Thanks to Christoph Gohlke for the patch.

Changes from 2.1 to 2.2
=======================

* [LICENSE] Fixed a problem with the license of the
  numexpr/win32/pthread.{c,h} files emulating pthreads on Windows
  platforms.  After persmission from the original authors is granted,
  these files adopt the MIT license and can be redistributed without
  problems.  See issue #109 for details
  (https://code.google.com/p/numexpr/issues/detail?id=110).

* [ENH] Improved the algorithm to decide the initial number of threads
  to be used.  This was necessary because by default, numexpr was
  using a number of threads equal to the detected number of cores, and
  this can be just too much for moder systems where this number can be
  too high (and counterporductive for performance in many cases).
  Now, the 'NUMEXPR_NUM_THREADS' environment variable is honored, and
  in case this is not present, a maximum number of *8* threads are
  setup initially.  The new algorithm is fully described in the Users
  Guide now in the note of 'General routines' section:
  https://code.google.com/p/numexpr/wiki/UsersGuide#General_routines.
  Closes #110.

* [ENH] numexpr.test() returns `TestResult` instead of None now.
  Closes #111.

* [FIX] Modulus with zero with integers no longer crashes the
  interpreter.  It nows puts a zero in the result.  Fixes #107.

* [API CLEAN] Removed `copy_args` argument of `evaluate`.  This should
  only be used by old versions of PyTables (< 3.0).

* [DOC] Documented the `optimization` and `truediv` flags of
  `evaluate` in Users Guide
  (https://code.google.com/p/numexpr/wiki/UsersGuide).

Changes from 2.0.1 to 2.1
===========================

* Dropped compatibility with Python < 2.6.

* Improve compatibiity with Python 3:

  - switch from PyString to PyBytes API (requires Python >= 2.6).
  - fixed incompatibilities regarding the int/long API
  - use the Py_TYPE macro
  - use the PyVarObject_HEAD_INIT macro instead of PyObject_HEAD_INIT

* Fixed several issues with different platforms not supporting
  multithreading or subprocess properly (see tickets #75 and #77).

* Now, when trying to use pure Python boolean operators, 'and',
  'or' and 'not', an error is issued suggesting that '&', '|' and
  '~' should be used instead (fixes #24).

Changes from 2.0 to 2.0.1
=========================

* Added compatibility with Python 2.5 (2.4 is definitely not supported
  anymore).

* `numexpr.evaluate` is fully documented now, in particular the new
  `out`, `order` and `casting` parameters.

* Reduction operations are fully documented now.

* Negative axis in reductions are not supported (they have never been
  actually), and a `ValueError` will be raised if they are used.


Changes from 1.x series to 2.0
==============================

- Added support for the new iterator object in NumPy 1.6 and later.

  This allows for better performance with operations that implies
  broadcast operations, fortran-ordered or non-native byte orderings.
  Performance for other scenarios is preserved (except for very small
  arrays).

- Division in numexpr is consistent now with Python/NumPy.  Fixes #22
  and #58.

- Constants like "2." or "2.0" must be evaluated as float, not
  integer.  Fixes #59.

- `evaluate()` function has received a new parameter `out` for storing
  the result in already allocated arrays.  This is very useful when
  dealing with large arrays, and a allocating new space for keeping
  the result is not acceptable.  Closes #56.

- Maximum number of threads raised from 256 to 4096.  Machines with a
  higher number of cores will still be able to import numexpr, but
  limited to 4096 (which is an absurdly high number already).

FITS (Flexible Image Transport System) is a data format most used in astronomy.
PyFITS is a Python module for reading, writing, and manipulating FITS files.
The module uses Python's object-oriented features to provide quick, easy, and
efficient access to FITS files. The use of Python's array syntax enables
immediate access to any FITS extension, header cards, or data items.

Changes to 2.4.0 (in py-pyfits):

Changelog
===========

3.2 (2013-11-26)
----------------

Highlights
^^^^^^^^^^

- Rewrote CFITSIO-based backend for handling tile compression of FITS files.
  It now uses a standard CFITSIO instead of heavily modified pieces of CFITSIO
  as before.  PyFITS ships with its own copy of CFITSIO v3.35 which supports
  the latest version of the Tiled Image Convention (v2.3), but system
  packagers may choose instead to strip this out in favor of a
  system-installed version of CFITSIO.  Earlier versions may work, but nothing
  earlier than 3.28 has been tested yet. (#169)

- Added support for reading and writing tables using the Q format for columns.
  The Q format is identical to the P format (variable-length arrays) except
  that it uses 64-bit integers for the data descriptors, allowing more than
  4 GB of variable-length array data in a single table. (#160)

- Added initial support for table columns containing pseudo-unsigned integers.
  This is currently enabled by using the ``uint=True`` option when opening
  files; any table columns with the correct BZERO value will be interpreted
  and returned as arrays of unsigned integers.

- Some refactoring of the table and ``FITS_rec`` modules in order to better
  separate the details of the FITS binary and ASCII table data structures from
  the HDU data structures that encapsulate them.  Most of these changes should
  not be apparent to users (but see API Changes below).


API Changes
^^^^^^^^^^^

- Assigning to values in ``ColDefs.names``, ``ColDefs.formats``,
  ``ColDefs.nulls`` and other attributes of ``ColDefs`` instances that return
  lists of column properties is no longer supported.  Assigning to those lists
  will no longer update the corresponding columns.  Instead, please just
  modify the ``Column`` instances directly (``Column.name``, ``Column.null``,
  etc.)

- The ``pyfits.new_table`` function is marked "pending deprecation".  This
  does not mean it will be removed outright or that its functionality has
  changed.  It will likely be replaced in the future for a function with
  similar, if not subtly different functionality.  A better, if not slightly
  more verbose approach is to use ``pyfits.FITS_rec.from_columns`` to create
  a new ``FITS_rec`` table--this has the same interface as
  ``pyfits.new_table``.  The difference is that it returns a plan ``FITS_rec``
  array, and not an HDU instance.  This ``FITS_rec`` object can then be used
  as the data argument in the constructors for ``BinTableHDU`` (for binary
  tables) or ``TableHDU`` (for ASCII tables).  This is analogous to creating
  an ``ImageHDU`` by passing in an image array.
  ``pyfits.FITS_rec.from_columns`` is just a simpler way of creating a
  FITS-compatible recarray from a FITS column specification.

- The ``updateHeader``, ``updateHeaderData``, and ``updateCompressedData``
  methods of the ``CompDataHDU`` class are pending deprecation and moved to
  internal methods.  The operation of these methods depended too much on
  internal state to be used safely by users; instead they are invoked
  automatically in the appropriate places when reading/writing compressed image
  HDUs.

- The ``CompDataHDU.compData`` attribute is pending deprecation in favor of
  the clearer and more PEP-8 compatible ``CompDataHDU.compressed_data``.

- The constructor for ``CompDataHDU`` has been changed to accept new keyword
  arguments.  The new keyword arguments are essentially the same, but are in
  underscore_separated format rather than camelCase format.  The old arguments
  are still pending deprecation.

- The internal attributes of HDU classes ``_hdrLoc``, ``_datLoc``, and
  ``_datSpan`` have been replaced with ``_header_offset``, ``_data_offset``,
  and ``_data_size`` respectively.  The old attribute names are still pending
  deprecation.  This should only be of interest to advanced users who have
  created their own HDU subclasses.

- The following previously deprecated functions and methods have been removed
  entirely: ``createCard``, ``createCardFromString``, ``upperKey``,
  ``ColDefs.data``, ``setExtensionNameCaseSensitive``, ``_File.getfile``,
  ``_TableBaseHDU.get_coldefs``, ``Header.has_key``, ``Header.ascardlist``.

  If you run your code with a previous version of PyFITS (>= 3.0, < 3.2) with
  the ``python -Wd`` argument, warnings for all deprecated interfaces still in
  use will be displayed.

- Interfaces that were pending deprecation are now fully deprecated.  These
  include: ``create_card``, ``create_card_from_string``, ``upper_key``,
  ``Header.get_history``, and ``Header.get_comment``.

- The ``.name`` attribute on HDUs is now directly tied to the HDU's header, so
  that if ``.header['EXTNAME']`` changes so does ``.name`` and vice-versa.

- The ``pyfits.file.PYTHON_MODES`` constant dict was renamed to
  ``pyfits.file.PYFITS_MODES`` which better reflects its purpose.  This is
  rarely used by client code, however.  Support for the old name will be
  removed by PyFITS 3.4.


Other Changes and Additions
^^^^^^^^^^^^^^^^^^^^^^^^^^^

- The new compression code also adds support for the ZQUANTIZ and ZDITHER0
  keywords added in more recent versions of this FITS Tile Compression spec.
  This includes support for lossless compression with GZIP. (#198) By default
  no dithering is used, but the ``SUBTRACTIVE_DITHER_1`` and
  ``SUBTRACTIVE_DITHER_2`` methods can be enabled by passing the correct
  constants to the ``quantize_method`` argument to the ``CompImageHDU``
  constuctor.  A seed can be manually specified, or automatically generated
  using either the system clock or checksum-based methods via the
  ``dither_seed`` argument.  See the documentation for ``CompImageHDU`` for
  more details. (#198) (spacetelescope/PYFITS#32)

- Images compressed with the Tile Compression standard can now be larger than
  4 GB through support of the Q format. (#159)

- All HDUs now have a ``.ver`` ``.level`` attribute that returns the value of
  the EXTVAL and EXTLEVEL keywords from that HDU's header, if the exist.  This
  was added for consistency with the ``.name`` attribute which returns the
  EXTNAME value from the header.

- Then ``Column`` and ``ColDefs`` classes have new ``.dtype`` attributes
  which give the Numpy dtype for the column data in the first case, and the
  full Numpy compound dtype for each table row in the latter case.

- There was an issue where new tables created defaulted the values in all
  string columns to '0.0'.  Now string columns are filled with empty strings
  by default--this seems a less surprising default, but it may cause
  differences with tables created with older versions of PyFITS.

- Improved round-tripping and preservation of manually assigned column
  attributes (``TNULLn``, ``TSCALn``, etc.) in table HDU headers.
  (astropy/astropy#996)


Bug Fixes
^^^^^^^^^

- Binary tables containing compressed images may, optionally, contain other
  columns unrelated to the tile compression convention. Although this is an
  uncommon use case, it is permitted by the standard. (#159)

- Reworked some of the file I/O routines to allow simpler, more consistent
  mapping between OS-level file modes ('rb', 'wb', 'ab', etc.) and the more
  "PyFITS-specific" modes used by PyFITS like "readonly" and "update".
  That is, if reading a FITS file from an open file object, it doesn't matter
  as much what "mode" it was opened in so long as it has the right
  capabilities (read/write/etc.)  Also works around bugs in the Python io
  module in 2.6+ with regard to file modes. (spacetelescope/PyFITS#33)

- Fixed an obscure issue that can occur on systems that don't have flush to
  memory-mapped files implemented (namely GNU Hurd). (astropy/astropy#968)


3.1.3 (2013-11-26)
------------------

- Disallowed assigning NaN and Inf floating point values as header values,
  since the FITS standard does not define a way to represent them in. Because
  this is undefined, the previous behavior did not make sense and produced
  invalid FITS files. (spacetelescope/PyFITS#11)

- Added a workaround for a bug in 64-bit OSX that could cause truncation when
  writing files greater than 2^32 bytes in size. (spacetelescope/PyFITS#28)

- Fixed a long-standing issue where writing binary tables did not correctly
  write the TFORMn keywords for variable-length array columns (they ommitted
  the max array length parameter of the format).  This was thought fixed in
  v3.1.2, but it was only fixed there for compressed image HDUs and not for
  binary tables in general.

- Fixed an obscure issue that can occur on systems that don't have flush to
  memory-mapped files implemented (namely GNU Hurd). (Backported from 3.2)


3.0.12 (2013-11-26)
-------------------

- Disallowed assigning NaN and Inf floating point values as header values,
  since the FITS standard does not define a way to represent them in. Because
  this is undefined, the previous behavior did not make sense and produced
  invalid FITS files. (Backported from 3.1.3)

- Added a workaround for a bug in 64-bit OSX that could cause truncation when
  writing files greater than 2^32 bytes in size. (Backported from 3.1.3)

- Fixed a long-standing issue where writing binary tables did not correctly
  write the TFORMn keywords for variable-length array columns (they ommitted
  the max array length parameter of the format).  This was thought fixed in
  v3.1.2, but it was only fixed there for compressed image HDUs and not for
  binary tables in general. (Backported from 3.1.3)

- Fixed an obscure issue that can occur on systems that don't have flush to
  memory-mapped files implemented (namely GNU Hurd). (Backported from 3.2)


3.1.2 (2013-04-22)
------------------

- When an error occurs opening a file in fitsdiff the exception message will
  now at least mention which file had the error. (#168)

- Fixed support for opening gzipped FITS files by filename in a writeable mode
  (PyFITS has supported writing to gzip files for some time now, but only
  enabled it when GzipFile objects were passed to ``pyfits.open()`` due to
  some legacy code preventing full gzip support. (#195)

- Added a more helpful error message in the case of malformatted FITS files
  that contain non-float NULL values in an ASCII table but are missing the
  required TNULLn keywords in the header. (#197)

- Fixed an (apparently long-standing) issue where writing compressed images
  did not correctly write the TFORMn keywords for variable-length array
  columns (they ommitted the max array length parameter of the format). (#199)

- Slightly refactored how tables containing variable-length array columns are
  handled to add two improvements: Fixes an issue where accessing the data
  after a call to the `pyfits.getdata` convenience function caused an
  exception, and allows the VLA data to be read from an existing mmap of the
  FITS file. (#200)

- Fixed a bug that could occur when opening a table containing
  multi-dimensional columns (i.e. via the TDIMn keyword) and then writing it
  out to a new file. (#201)

- Added use of the console_scripts entry point to install the fitsdiff and
  fitscheck scripts, which if nothing else provides better Windows support.
  The generated scripts now override the ones explicitly defined in the
  scripts/ directory (which were just trivial stubs to begin with). (#202)

- Fixed a bug on Python 3 where attempting to open a non-existent file on
  Python 3 caused a seemingly unrelated traceback. (#203)

- Fixed a bug in fitsdiff that reported two header keywords containing NaN
  as value as different. (#204)

- Fixed an issue in the tests that caused some tests to fail if pyfits is
  installed with read-only permissions. (#208)

- Fixed a bug where instantiating a ``BinTableHDU`` from a numpy array
  containing boolean fields converted all the values to ``False``. (#215)

- Fixed an issue where passing an array of integers into the constructor of
  ``Column()`` when the column type is floats of the same byte width caused the
  column array to become garbled. (#218)

- Fixed inconsistent behavior in creating CONTINUE cards from byte strings
  versus unicode strings in Python 2--CONTINUE cards can now be created
  properly from unicode strings (so long as they are convertable to ASCII).
  (spacetelescope/PyFITS#1)

- Fixed a couple cases where creating a new table using TDIMn in some of the
  columns could caused a crash. (spacetelescope/PyFITS#3)

- Fixed a bug in parsing HIERARCH keywords that do not have a space after
  the first equals sign (before the value). (spacetelescope/PyFITS#5)

- Prevented extra leading whitespace on HIERARCH keywords from being treated
  as part of the keyword. (spacetelescope/PyFITS#6)

- Fixed a bug where HIERARCH keywords containing lower-case letters was
  mistakenly marked as invalid during header validation.
  (spacetelescope/PyFITS#7)

- Fixed an issue that was ancillary to (spacetelescope/PyFITS#7) where the
  ``Header.index()`` method did not work correctly with HIERARCH keywords
  containing lower-case letters.


3.0.11 (2013-04-17)
-------------------

- Fixed support for opening gzipped FITS files by filename in a writeable mode
  (PyFITS has supported writing to gzip files for some time now, but only
  enabled it when GzipFile objects were passed to ``pyfits.open()`` due to
  some legacy code preventing full gzip support. Backported from 3.1.2. (#195)

  columns could caused a crash. Backported from 3.1.2.
  (spacetelescope/PyFITS#3)


3.1.1 (2013-01-02)
------------------

This is a bug fix release for the 3.1.x series.

Bug Fixes
^^^^^^^^^

- Improved handling of scaled images and pseudo-unsigned integer images in
  compressed image HDUs.  They now work more transparently like normal image
  HDUs with support for the ``do_not_scale_image_data`` and ``uint`` options,
  as well as ``scale_back`` and ``save_backup``.  The ``.scale()`` method
  works better too. (#88)

- Permits non-string values for the EXTNAME keyword when reading in a file,
  rather than throwing an exception due to the malformatting.  Added
  verification for the format of the EXTNAME keyword when writing. (#96)

- Added support for EXTNAME and EXTVER in PRIMARY HDUs.  That is, if EXTNAME
  is specified in the header, it will also be reflected in the ``.name``
  attribute and in ``pyfits.info()``.  These keywords used to be verboten in
  PRIMARY HDUs, but the latest version of the FITS standard allows them.
  (#151)

- HCOMPRESS can again be used to compress data cubes (and higher-dimensional
  arrays) so long as the tile size is effectively 2-dimensional. In fact,
  PyFITS will automatically use compatible tile sizes even if they're not
  explicitly specified. (#171)

- Added support for the optional ``endcard`` parameter in the
  ``Header.fromtextfile()`` and ``Header.totextfile()`` methods.  Although
  ``endcard=False`` was a reasonable default assumption, there are still text
  dumps of FITS headers that include the END card, so this should have been
  more flexible. (#176)

- Fixed a crash when running fitsdiff on two empty (that is, zero row) tables.
  (#178)

- Fixed an issue where opening files containing random groups HDUs in update
  mode could cause an unnecessary rewrite of the file even if none of the
  data is modified. (#179)

- Fixed a bug that could caused a deadlock in the filesystem on OSX if PyFITS
  is used with Numpy 1.7 in some cases. (#180)

- Fixed a crash when generating diff reports from diffs using the
  ``ignore_comments`` options. (#181)

- Fixed some bugs with WCS Paper IV record-valued keyword cards:

  - Cards that looked kind of like RVKCs but were not intended to be were
    over-permissively treated as such--commentary keywords like COMMENT and
    HISTORY were particularly affected. (#183)

  - Looking up a card in a header by its standard FITS keyword only should
    always return the raw value of that card.  That way cards containing
    values that happen to valid RVKCs but were not intended to be will still
    be treated like normal cards. (#184)

  - Looking up a RVKC in a header with only part of the field-specifier (for
    example "DP1.AXIS" instead of "DP1.AXIS.1") was implicitly treated as a
    wildcard lookup. (#184)

- Fixed a crash when diffing two FITS files where at least one contains a
  compressed image HDU which was not recognized as an image instead of a
  table. (#187)

- Fixed bugs in the backwards compatibility layer for the ``CardList.index``
  and ``CardList.count`` methods. (#190)

- Improved ``__repr__`` and text file representation of cards with long values
  that are split into CONTINUE cards. (#193)

- Fixed a crash when trying to assign a long (> 72 character) value to blank
  ('') keywords. This also changed how blank keywords are represented--there
  are still exactly 8 spaces before any commentary content can begin; this
  *may* affect the exact display of header cards that assumed there could be
  fewer spaces in a blank keyword card before the content begins. However, the
  current approach is more in line with the requirements of the FITS standard.
  (#194)


3.0.10 (2013-01-02)
-------------------

- Improved handling of scaled images and pseudo-unsigned integer images in
  compressed image HDUs.  They now work more transparently like normal image
  HDUs with support for the ``do_not_scale_image_data`` and ``uint`` options,
  as well as ``scale_back`` and ``save_backup``.  The ``.scale()`` method
  works better too.  Backported from 3.1.1. (#88)

- Permits non-string values for the EXTNAME keyword when reading in a file,
  rather than throwing an exception due to the malformatting.  Added
  verification for the format of the EXTNAME keyword when writing.  Backported
  from 3.1.1. (#96)

- Added support for EXTNAME and EXTVER in PRIMARY HDUs.  That is, if EXTNAME
  is specified in the header, it will also be reflected in the ``.name``
  attribute and in ``pyfits.info()``.  These keywords used to be verbotten in
  PRIMARY HDUs, but the latest version of the FITS standard allows them.
  Backported from 3.1.1. (#151)

- HCOMPRESS can again be used to compress data cubes (and higher-dimensional
  arrays) so long as the tile size is effectively 2-dimensional. In fact,
  PyFITS will not automatically use compatible tile sizes even if they're not
  explicitly specified.  Backported from 3.1.1. (#171)

- Fixed a bug when writing out files containing zero-width table columns,
  where the TFIELDS keyword would be updated incorrectly, leaving the table
  largely unreadable.  Backported from 3.1.0. (#174)

- Fixed an issue where opening files containing random groups HDUs in update
  mode could cause an unnecessary rewrite of the file even if none of the
  data is modified.  Backported from 3.1.1. (#179)

- Fixed a bug that could caused a deadlock in the filesystem on OSX if PyFITS
  is used with Numpy 1.7 in some cases. Backported from 3.1.1. (#180)


3.1 (2012-08-08)
----------------

Highlights
^^^^^^^^^^

- The ``Header`` object has been significantly reworked, and ``CardList``
  objects are now deprecated (their functionality folded into the ``Header``
  class).  See API Changes below for more details.

- Memory maps are now used by default to access HDU data.  See API Changes
  below for more details.

- Now includes a new version of the ``fitsdiff`` program for comparing two
  FITS files, and a new FITS comparison API used by ``fitsdiff``.  See New
  Features below.

API Changes
^^^^^^^^^^^

- The ``Header`` class has been rewritten, and the ``CardList`` class is
  deprecated.  Most of the basic details of working with FITS headers are
  unchanged, and will not be noticed by most users.  But there are differences
  in some areas that will be of interest to advanced users, and to application
  developers.  For full details of the changes, see the "Header Interface
  Transition Guide" section in the PyFITS documentation.  See ticket #64 on
  the PyFITS Trac for futher details and background. Some highlights are
  listed below:

  * The Header class now fully implements the Python dict interface, and can
    be used interchangably with a dict, where the keys are header keywords.

  * New keywords can be added to the header using normal keyword assignment
    (previously it was necessary to use ``Header.update`` to add new
    keywords).  For example::

        >>> header['NAXIS'] = 2

    will update the existing 'FOO' keyword if it already exists, or add a new
    one if it doesn't exist, just like a dict.

  * It is possible to assign both a value and a comment at the same time using
    a tuple::

        >>> header['NAXIS'] = (2, 'Number of axes')

  * To add/update a new card and ensure it's added in a specific location, use
    ``Header.set()``::

        >>> header.set('NAXIS', 2, 'Number of axes', after='BITPIX')

    This works the same as the old ``Header.update()``.  ``Header.update()``
    still works in the old way too, but is deprecated.

  * Although ``Card`` objects still exist, it generally is not necessary to
    work with them directly.  ``Header.ascardlist()``/``Header.ascard`` are
    deprecated and should not be used.  To directly access the ``Card``
    objects in a header, use ``Header.cards``.

  * To access card comments, it is still possible to either go through the
    card itself, or through ``Header.comments``.  For example::

       >>> header.cards['NAXIS'].comment
       Number of axes
       >>> header.comments['NAXIS']
       Number of axes

  * ``Card`` objects can now be used interchangeably with
    ``(keyword, value, comment)`` 3-tuples.  They still have ``.value`` and
    ``.comment`` attributes as well.  The ``.key`` attribute has been renamed
    to ``.keyword`` for consistency, though ``.key`` is still supported (but
    deprecated).

- Memory mapping is now used by default to access HDU data.  That is,
  ``pyfits.open()`` uses ``memmap=True`` as the default.  This provides better
  performance in the majority of use cases--there are only some I/O intensive
  applications where it might not be desirable.  Enabling mmap by default also
  enabled finding and fixing a large number of bugs in PyFITS' handling of
  memory-mapped data (most of these bug fixes were backported to PyFITS
  3.0.5). (#85)

  * A new ``pyfits.USE_MEMMAP`` global variable was added.  Set
    ``pyfits.USE_MEMMAP = False`` to change the default memmap setting for
    opening files.  This is especially useful for controlling the behavior in
    applications where pyfits is deeply embedded.

  * Likewise, a new ``PYFITS_USE_MEMMAP`` environment variable is supported.
    Set ``PYFITS_USE_MEMMAP = 0`` in your environment to change the default
    behavior.

- The ``size()`` method on HDU objects is now a ``.size`` property--this
  returns the size in bytes of the data portion of the HDU, and in most cases
  is equivalent to ``hdu.data.nbytes`` (#83)

- ``BinTableHDU.tdump`` and ``BinTableHDU.tcreate`` are deprecated--use
  ``BinTableHDU.dump`` and ``BinTableHDU.load`` instead.  The new methods
  output the table data in a slightly different format from previous versions,
  which places quotes around each value.  This format is compatible with data
  dumps from previous versions of PyFITS, but not vice-versa due to a parsing
  bug in older versions.

- Likewise the ``pyfits.tdump`` and ``pyfits.tcreate`` convenience function
  versions of these methods have been renamed ``pyfits.tabledump`` and
  ``pyfits.tableload``.  The old deprecated, but currently retained for
  backwards compatibility. (r1125)

- A new global variable ``pyfits.EXTENSION_NAME_CASE_SENSITIVE`` was added.
  This serves as a replacement for ``pyfits.setExtensionNameCaseSensitive``
  which is not deprecated and may be removed in a future version.  To enable
  case-sensitivity of extension names (i.e. treat 'sci' as distict from 'SCI')
  set ``pyfits.EXTENSION_NAME_CASE_SENSITIVE = True``.  The default is
  ``False``. (r1139)

- A new global configuration variable ``pyfits.STRIP_HEADER_WHITESPACE`` was
  added.  By default, if a string value in a header contains trailing
  whitespace, that whitespace is automatically removed when the value is read.
  Now if you set ``pyfits.STRIP_HEADER_WHITESPACE = False`` all whitespace is
  preserved. (#146)

- The old ``classExtensions`` extension mechanism (which was deprecated in
  PyFITS 3.0) is removed outright.  To our knowledge it was no longer used
  anywhere. (r1309)

- Warning messages from PyFITS issued through the Python warnings API are now
  output to stderr instead of stdout, as is the default.  PyFITS no longer
  modifies the default behavior of the warnings module with respect to which
  stream it outputs to. (r1319)

- The ``checksum`` argument to ``pyfits.open()`` now accepts a value of
  'remove', which causes any existing CHECKSUM/DATASUM keywords to be ignored,
  and removed when the file is saved.

New Features
^^^^^^^^^^^^

- Added support for the proposed "FITS" extension HDU type.  See
  http://listmgr.cv.nrao.edu/pipermail/fitsbits/2002-April/001094.html.  FITS
  HDUs contain an entire FITS file embedded in their data section.  `FitsHDU`
  objects work like other HDU types in PyFITS.  Their ``.data`` attribute
  returns the raw data array.  However, they have a special ``.hdulist``
  attribute which processes the data as a FITS file and returns it as an
  in-memory HDUList object.  FitsHDU objects also support a
  ``FitsHDU.fromhdulist()`` classmethod which returns a new `FitsHDU` object
  that embeds the supplied HDUList. (#80)

- Added a new ``.is_image`` attribute on HDU objects, which is True if the HDU
  data is an 'image' as opposed to a table or something else.  Here the
  meaning of 'image' is fairly loose, and mostly just means a Primary or Image
  extension HDU, or possibly a compressed image HDU (#71)

- Added an ``HDUList.fromstring`` classmethod which can parse a FITS file
  already in memory and instantiate and ``HDUList`` object from it.  This
  could be useful for integrating PyFITS with other libraries that work on
  FITS file, such as CFITSIO.  It may also be useful in streaming
  applications.  The name is a slight misnomer, in that it actually accepts
  any Python object that implements the buffer interface, which includes
  ``bytes``, ``bytearray``, ``memoryview``, ``numpy.ndarray``, etc. (#90)

- Added a new ``pyfits.diff`` module which contains facilities for comparing
  FITS files.  One can use the ``pyfits.diff.FITSDiff`` class to compare two
  FITS files in their entirety.  There is also a ``pyfits.diff.HeaderDiff``
  class for just comparing two FITS headers, and other similar interfaces.
  See the PyFITS Documentation for more details on this interface.  The
  ``pyfits.diff`` module powers the new ``fitsdiff`` program installed with
  PyFITS.  After installing PyFITS, run ``fitsdiff --help`` for usage details.

- ``pyfits.open()`` now accepts a ``scale_back`` argument.  If set to
  ``True``, this automatically scales the data using the original BZERO and
  BSCALE parameters the file had when it was first opened, if any, as well as
  the original BITPIX.  For example, if the original BITPIX were 16, this
  would be equivalent to calling ``hdu.scale('int16', 'old')`` just before
  calling ``flush()`` or ``close()`` on the file.  This option applies to all
  HDUs in the file. (#120)

- ``pyfits.open()`` now accepts a ``save_backup`` argument.  If set to
  ``True``, this automatically saves a backup of the original file before
  flushing any changes to it (this of course only applies to update and append
  mode).  This may be especially useful when working with scaled image data.
  (#121)

Changes in Behavior
^^^^^^^^^^^^^^^^^^^

- Warnings from PyFITS are not output to stderr by default, instead of stdout
  as it has been for some time.  This is contrary to most users' expectations
  and makes it more difficult for them to separate output from PyFITS from the
  desired output for their scripts. (r1319)

Bug Fixes
^^^^^^^^^

- Fixed ``pyfits.tcreate()`` (now ``pyfits.tableload()``) to be more robust
  when encountering blank lines in a column definition file (#14)

- Fixed a fairly rare crash that could occur in the handling of CONTINUE cards
  when using Numpy 1.4 or lower (though 1.4 is the oldest version supported by
  PyFITS). (r1330)

- Fixed ``_BaseHDU.fromstring`` to actually correctly instantiate an HDU
  object from a string/buffer containing the header and data of that HDU.
  This allowed for the implementation of ``HDUList.fromstring`` described
  above. (#90)

- Fixed a rare corner case where, in some use cases, (mildly, recoverably)
  malformatted float values in headers were not properly returned as floats.
  (#137)

- Fixed a corollary to the previous bug where float values with a leading zero
  before the decimal point had the leading zero unnecessarily removed when
  saving changes to the file (eg. "0.001" would be written back as ".001" even
  if no changes were otherwise made to the file). (#137)

- When opening a file containing CHECKSUM and/or DATASUM keywords in update
  mode, the CHECKSUM/DATASUM are updated and preserved even if the file was
  opened with checksum=False.  This change in behavior prevents checksums from
  being unintentionally removed. (#148)

- Fixed a bug where ``ImageHDU.scale(option='old')`` wasn't working at all--it
  was not restoring the image to its original BSCALE and BZERO values. (#162)

- Fixed a bug when writing out files containing zero-width table columns,
  where the TFIELDS keyword would be updated incorrectly, leaving the table
  largely unreadable.  This fix will be backported to the 3.0.x series in
  version 3.0.10.  (#174)


3.0.9 (2012-08-06)
------------------

This is a bug fix release for the 3.0.x series.

Bug Fixes
^^^^^^^^^

- Fixed ``Header.values()``/``Header.itervalues()`` and ``Header.items()``/
  ``Header.iteritems()`` to correctly return the different values for
  duplicate keywords (particularly commentary keywords like HISTORY and
  COMMENT).  This makes the old Header implementation slightly more compatible
  with the new implementation in PyFITS 3.1. (#127)

  .. note::
      This fix did not change the existing behavior from earlier PyFITS
      versions where ``Header.keys()`` returns all keywords in the header with
      duplicates removed.  PyFITS 3.1 changes that behavior, so that
      ``Header.keys()`` includes duplicates.

- Fixed a bug where ``ImageHDU.scale(option='old')`` wasn't working at all--it
  was not restoring the image to its original BSCALE and BZERO values. (#162)

- Fixed a bug where opening a file containing compressed image HDUs in
  'update' mode and then immediately closing it without making any changes
  caused the file to be rewritten unncessarily. (#167)

- Fixed two memory leaks that could occur when writing compressed image data,
  or in some cases when opening files containing compressed image HDUs in
  'update' mode. (#168)


3.0.8 (2012-06-04)
------------------

Changes in Behavior
^^^^^^^^^^^^^^^^^^^

- Prior to this release, image data sections did not work with scaled
  data--that is, images with non-trivial BSCALE and/or BZERO values.
  Previously, in order to read such images in sections, it was necessary to
  manually apply the BSCALE+BZERO to each section.  It's worth noting that
  sections *did* support pseudo-unsigned ints (flakily).  This change just
  extends that support for general BSCALE+BZERO values.

Bug Fixes
^^^^^^^^^

- Fixed a bug that prevented updates to values in boolean table columns from
  being saved.  This turned out to be a symptom of a deeper problem that could
  prevent other table updates from being saved as well. (#139)

- Fixed a corner case in which a keyword comment ending with the string "END"
  could, in some circumstances, cause headers (and the rest of the file after
  that point) to be misread. (#142)

- Fixed support for scaled image data and psuedo-unsigned ints in image data
  sections (``hdu.section``).  Previously this was not supported at all.  At
  some point support was supposedly added, but it was buggy and incomplete.
  Now the feature seems to work much better. (#143)

- Fixed the documentation to point out that image data sections *do* support
  non-contiguous slices (and have for a long time).  The documentation was
  never updated to reflect this, and misinformed users that only contiguous
  slices were supported, leading to some confusion. (#144)

- Fixed a bug where creating an ``HDUList`` object containing multiple PRIMARY
  HDUs caused an infinite recursion when validating the object prior to
  writing to a file. (#145)

- Fixed a rare but serious case where saving an update to a file that
  previously had a CHECKSUM and/or DATASUM keyword, but removed the checksum
  in saving, could cause the file to be slightly corrupted and unreadable.
  (#147)

- Fixed problems with reading "non-standard" FITS files with primary headers
  containing SIMPLE = F.  PyFITS has never made many guarantees as to how such
  files are handled.  But it should at least be possible to read their
  headers, and the data if possible.  Saving changes to such a file should not
  try to prepend an unwanted valid PRIMARY HDU. (#157)

- Fixed a bug where opening an image with ``disable_image_compression = True``
  caused compression to be disabled for all subsequent ``pyfits.open()`` calls.
  (r1651)


3.0.7 (2012-04-10)
------------------

Changes in Behavior
^^^^^^^^^^^^^^^^^^^

- Slices of GroupData objects now return new GroupData objects instead of
  extended multi-row _Group objects. This is analogous to how PyFITS 3.0 fixed
  FITS_rec slicing, and should have been fixed for GroupData at the same time.
  The old behavior caused bugs where functions internal to Numpy expected that
  slicing an ndarray would return a new ndarray.  As this is a rare usecase
  with a rare feature most users are unlikely to be affected by this change.

- The previously internal _Group object for representing individual group
  records in a GroupData object are renamed Group and are now a public
  interface.  However, there's almost no good reason to create Group objects
  directly, so it shouldn't be considered a "new feature".

- An annoyance from PyFITS 3.0.6 was fixed, where the value of the EXTEND
  keyword was always being set to F if there are not actually any extension
  HDUs.  It was unnecessary to modify this value.

Bug Fixes
^^^^^^^^^

- Fixed GroupData objects to return new GroupData objects when sliced instead
  of _Group record objects.  See "Changes in behavior" above for more details.

- Fixed slicing of Group objects--previously it was not possible to slice
  slice them at all.

- Made it possible to assign `np.bool_` objects as header values. (#123)

- Fixed overly strict handling of the EXTEND keyword; see "Changes in
  behavior" above. (#124)

- Fixed many cases where an HDU's header would be marked as "modified" by
  PyFITS and rewritten, even when no changes to the header are necessary.
  (#125)

- Fixed a bug where the values of the PTYPEn keywords in a random groups HDU
  were forced to be all lower-case when saving the file. (#130)

- Removed an unnecessary inline import in `ExtensionHDU.__setattr__` that was
  causing some slowdown when opening files containing a large number of
  extensions, plus a few other small (but not insignficant) performance
  improvements thanks to Julian Taylor. (#133)

- Fixed a regression where header blocks containing invalid end-of-header
  padding (i.e. null bytes instead of spaces) couldn't be parsed by PyFITS.
  Such headers can be parsed again, but a warning is raised, as such headers
  are not valid FITS. (#136)

- Fixed a memory leak where table data in random groups HDUs weren't being
  garbage collected. (#138)


3.0.6 (2012-02-29)
------------------

Highlights
^^^^^^^^^^

The main reason for this release is to fix an issue that was introduced in
PyFITS 3.0.5 where merely opening a file containing scaled data (that is, with
non-trivial BSCALE and BZERO keywords) in 'update' mode would cause the data
to be automatically rescaled--possibly converting the data from ints to
floats--as soon as the file is closed, even if the application did not touch
the data.  Now PyFITS will only rescale the data in an extension when the data
is actually accessed by the application.  So opening a file in 'update' mode
in order to modify the header or append new extensions will not cause any
change to the data in existing extensions.

This release also fixes a few Windows-specific bugs found through more
extensive Windows testing, and other miscellaneous bugs.

Bug Fixes
^^^^^^^^^

- More accurate error messages when opening files containing invalid header
  cards. (#109)

- Fixed a possible reference cycle/memory leak that was caught through more
  extensive testing on Windows. (#112)

- Fixed 'ostream' mode to open the underlying file in 'wb' mode instead of 'w'
  mode. (#112)

- Fixed a Windows-only issue where trying to save updates to a resized FITS
  file could result in a crash due to there being open mmaps on that file.
  (#112)

- Fixed a crash when trying to create a FITS table (i.e. with new_table())
  from a Numpy array containing bool fields. (#113)

- Fixed a bug where manually initializing an ``HDUList`` with a list of of
  HDUs wouldn't set the correct EXTEND keyword value on the primary HDU.
  (#114)

- Fixed a crash that could occur when trying to deepcopy a Header in Python <
  2.7. (#115)

- Fixed an issue where merely opening a scaled image in 'update' mode would
  cause the data to be converted to floats when the file is closed. (#119)


3.0.5 (2012-01-30)
------------------

- Fixed a crash that could occur when accessing image sections of files
  opened with memmap=True. (r1211)

- Fixed the inconsistency in the behavior of files opened in 'readonly' mode
  when memmap=True vs. when memmap=False.  In the latter case, although
  changes to array data were not saved to disk, it was possible to update the
  array data in memory.  On the other hand with memmap=True, 'readonly' mode
  prevented even in-memory modification to the data.  This is what
  'copyonwrite' mode was for, but difference in behavior was confusing.  Now
  'readonly' is equivalent to 'copyonwrite' when using memmap.  If the old
  behavior of denying changes to the array data is necessary, a new
  'denywrite' mode may be used, though it is only applicable to files opened
  with memmap. (r1275)

- Fixed an issue where files opened with memmap=True would return image data
  as a raw numpy.memmap object, which can cause some unexpected
  behaviors--instead memmap object is viewed as a numpy.ndarray. (r1285)

- Fixed an issue in Python 3 where a workaround for a bug in Numpy on Python 3
  interacted badly with some other software, namely to vo.table package (and
  possibly others). (r1320, r1337, and #110)

- Fixed buggy behavior in the handling of SIGINTs (i.e. Ctrl-C keyboard
  interrupts) while flushing changes to a FITS file.  PyFITS already prevented
  SIGINTs from causing an incomplete flush, but did not clean up the signal
  handlers properly afterwards, or reraise the keyboard interrupt once the
  flush was complete. (r1321)

- Fixed a crash that could occur in Python 3 when opening files with checksum
  checking enabled. (r1336)

- Fixed a small bug that could cause a crash in the `StreamingHDU` interface
  when using Numpy below version 1.5.

- Fixed a crash that could occur when creating a new `CompImageHDU` from an
  array of big-endian data. (#104)

- Fixed a crash when opening a file with extra zero padding at the end.
  Though FITS files should not have such padding, it's not explictly forbidden
  by the format either, and PyFITS shouldn't stumble over it. (#106)

- Fixed a major slowdown in opening tables containing large columns of string
  values.  (#111)


3.0.4 (2011-11-22)
------------------

- Fixed a crash when writing HCOMPRESS compressed images that could happen on
  Python 2.5 and 2.6. (r1217)

- Fixed a crash when slicing an table in a file opened in 'readonly' mode with
  memmap=True. (r1230)

- Writing changes to a file or writing to a new file verifies the output in
  'fix' mode by default instead of 'exception'--that is, PyFITS will
  automatically fix common FITS format errors rather than raising an
  exception. (r1243)

- Fixed a bug where convenience functions such as getval() and getheader()
  crashed when specifying just 'PRIMARY' as the extension to use (r1263).

- Fixed a bug that prevented passing keyword arguments (beyond the standard
  data and header arguments) as positional arguments to the constructors of
  extension HDU classes.

- Fixed some tests that were failing on Windows--in this case the tests
  themselves failed to close some temp files and Windows refused to delete them
  while there were still open handles on them. (r1295)

- Fixed an issue with floating point formatting in header values on Python 2.5
  for Windows (and possibly other platforms).  The exponent was zero-padded to
  3 digits; although the FITS standard makes no specification on this, the
  formatting is now normalized to always pad the exponent to two digits.
  (r1295)

- Fixed a bug where long commentary cards (such as HISTORY and COMMENT) were
  broken into multiple CONTINUE cards.  However, commentary cards are not
  expected to be found in CONTINUE cards.  Instead these long cards are broken
  into multiple commentary cards. (#97)

- GZIP/ZIP-compressed FITS files can be detected and opened regardless of
  their filename extension. (#99)

- Fixed a serious bug where opening scaled images in 'update' mode and then
  closing the file without touching the data would cause the file to be
  corrupted. (#101)


3.0.3 (2011-10-05)
------------------

- Fixed several small bugs involving corner cases in record-valued keyword
  cards (#70)

- In some cases HDU creation failed if the first keyword value in the header
  was not a string value (#89)

- Fixed a crash when trying to compute the HDU checksum when the data array
  contains an odd number of bytes (#91)

- Disabled an unnecessary warning that was displayed on opening compressed
  HDUs with disable_image_compression = True (#92)

- Fixed a typo in code for handling HCOMPRESS compressed images.


3.0.2 (2011-09-23)
------------------

- The ``BinTableHDU.tcreate`` method and by extension the ``pyfits.tcreate``
  function don't get tripped up by blank lines anymore (#14)

- The presence, value, and position of the EXTEND keyword in Primary HDUs is
  verified when reading/writing a FITS file (#32)

- Improved documentation (in warning messages as well as in the handbook) that
  PyFITS uses zero-based indexing (as one would expect for C/Python code, but
  contrary to the PyFITS standard which was written with FORTRAN in mind)
  (#68)

- Fixed a bug where updating a header card comment could cause the value to be
  lost if it had not already been read from the card image string.

- Fixed a related bug where changes made directly to Card object in a header
  (i.e. assigning directly to card.value or card.comment) would not propagate
  when flushing changes to the file (#69) [Note: This and the bug above it
  were originally reported as being fixed in version 3.0.1, but the fix was
  never included in the release.]

- Improved file handling, particularly in Python 3 which had a few small file
  I/O-related bugs (#76)

- Fixed a bug where updating a FITS file would sometimes cause it to lose its
  original file permissions (#79)

- Fixed the handling of TDIMn keywords; 3.0 added support for them, but got
  the axis order backards (they were treated as though they were row-major)
  (#82)

- Fixed a crash when a FITS file containing scaled data is opened and
  immediately written to a new file without explicitly viewing the data first
  (#84)

- Fixed a bug where creating a table with columns named either 'names' or
  'formats' resulted in an infinite recursion (#86)


3.0.1 (2011-09-12)
------------------

- Fixed a bug where updating a header card comment could cause the value to be
  lost if it had not already been read from the card image string.

- Changed ``_TableBaseHDU.data`` so that if the data contain an empty table a
  ``FITS_rec`` object with zero rows is returned rather than ``None``.

- The ``.key`` attribute of ``RecordValuedKeywordCards`` now returns the full
  keyword+field-specifier value, instead of just the plain keyword (#46)

- Fixed a related bug where changes made directly to Card object in a header
  (i.e. assigning directly to card.value or card.comment) would not propagate
  when flushing changes to the file (#69)

- Fixed a bug where writing a table with zero rows could fail in some cases
  (#72)

- Miscellanous small bug fixes that were causing some tests to fail,
  particularly on Python 3 (#74, #75)

- Fixed a bug where creating a table column from an array in non-native byte
  order would not preserve the byte order, thus interpreting the column array
  using the wrong byte order (#77)


3.0.0 (2011-08-23)
--------------------

- Contains major changes, bumping the version to 3.0

- Large amounts of refactoring and reorganization of the code; tried to
  preserve public API backwards-compatibility with older versions (private API
  has many changes and is not guaranteed to be backwards-compatible).  There
  are a few small public API changes to be aware of:

  * The pyfits.rec module has been removed completely.  If your version of
    numpy does not have the numpy.core.records module it is too old to be used
    with PyFITS.

  * The ``Header.ascardlist()`` method is deprecated--use the ``.ascard``
    attribute instead.

  * ``Card`` instances have a new ``.cardimage`` attribute that should be used
    rather than ``.ascardimage()``, which may become deprecated.

  * The ``Card.fromstring()`` method is now a classmethod.  It returns a new
    ``Card`` instance rather than modifying an existing instance.

  * The ``req_cards()`` method on HDU instances has changed:  The ``pos``
    argument is not longer a string.  It is either an integer value (meaning
    the card's position must match that value) or it can be a function that
    takes the card's position as it's argument, and returns True if the
    position is valid.  Likewise, the ``test`` argument no longer takes a
    string, but instead a function that validates the card's value and returns
    True or False.

  * The ``get_coldefs()`` method of table HDUs is deprecated.  Use the
    ``.columns`` attribute instead.

  * The ``ColDefs.data`` attribute is deprecated--use ``ColDefs.columns``
    instead (though in general you shouldn't mess with it directly--it might
    become internal at some point).

  * ``FITS_record`` objects take ``start`` and ``end`` as arguments instead of
    ``startColumn`` and ``endColumn`` (these are rarely created manually, so
    it's unlikely that this change will affect anyone).

  * ``BinTableHDU.tcreate()`` is now a classmethod, and returns a new
    ``BinTableHDU`` instance.

  * Use ``ExtensionHDU`` and ``NonstandardExtHDU`` for making new extension HDU
    classes.  They are now public interfaces, wheres previously they were
    private and prefixed with underscores.

  * Possibly others--please report if you find any changes that cause
    difficulties.

- Calls to deprecated functions will display a Deprecation warning.  However,
  in Python 2.7 and up Deprecation warnings are ignored by default, so run
  Python with the `-Wd` option to see if you're using any deprecated
  functions.  If we get close to actually removing any functions, we might
  make the Deprecation warnings display by default.

- Added basic Python 3 support

- Added support for multi-dimensional columns in tables as specified by the
  TDIMn keywords (#47)

- Fixed a major memory leak that occurred when creating new tables with the
  ``new_table()`` function (#49)
  be padded with zero-bytes) vs ASCII tables (where strings are padded with
  spaces) (#15)

- Fixed a bug in which the case of Random Access Group parameters names was not
  preserved when writing (#41)

- Added support for binary table fields with zero width (#42)

- Added support for wider integer types in ASCII tables; although this is non-
  standard, some GEIS images require it (#45)

- Fixed a bug that caused the index_of() method of HDULists to crash when the
  HDUList object is created from scratch (#48)

- Fixed the behavior of string padding in binary tables (where strings should
  be padded with nulls instead of spaces)

- Fixed a rare issue that caused excessive memory usage when computing
  checksums using a non-standard block size (see r818)

- Add support for forced uint data in image sections (#53)

- Fixed an issue where variable-length array columns were not extended when
  creating a new table with more rows than the original (#54)

- Fixed tuple and list-based indexing of FITS_rec objects (#55)

- Fixed an issue where BZERO and BSCALE keywords were appended to headers in
  the wrong location (#56)

- ``FITS_record`` objects (table rows) have full slicing support, including
  stepping, etc. (#59)

- Fixed a bug where updating multiple files simultaneously (such as when
  running parallel processes) could lead to a race condition with mktemp()
  (#61)

- Fixed a bug where compressed image headers were not in the order expected by
  the funpack utility (#62)
jperkin pushed a commit that referenced this issue Mar 14, 2014
Changes from 2.2.1 to 2.2.2
===========================

* The `copy_args` argument of `NumExpr` function has been brought
  back.  This has been mainly necessary for compatibility with
  PyTables < 3.0, which I decided to continue to support.  Fixed #115.

* The `__nonzero__` method in `ExpressionNode` class has been
  commented out.  This is also for compatibility with PyTables < 3.0.
  See #24 for details.

* Fixed the type of some parameters in the C extension so that s390
  architecture compiles.  Fixes #116.  Thank to Antonio Valentino for
  reporting and the patch.


Changes from 2.2 to 2.2.1
=========================

* Fixes a secondary effect of "from numpy.testing import `*`", where
  division is imported now too, so only then necessary functions from
  there are imported now.  Thanks to Christoph Gohlke for the patch.

Changes from 2.1 to 2.2
=======================

* [LICENSE] Fixed a problem with the license of the
  numexpr/win32/pthread.{c,h} files emulating pthreads on Windows
  platforms.  After persmission from the original authors is granted,
  these files adopt the MIT license and can be redistributed without
  problems.  See issue #109 for details
  (https://code.google.com/p/numexpr/issues/detail?id=110).

* [ENH] Improved the algorithm to decide the initial number of threads
  to be used.  This was necessary because by default, numexpr was
  using a number of threads equal to the detected number of cores, and
  this can be just too much for moder systems where this number can be
  too high (and counterporductive for performance in many cases).
  Now, the 'NUMEXPR_NUM_THREADS' environment variable is honored, and
  in case this is not present, a maximum number of *8* threads are
  setup initially.  The new algorithm is fully described in the Users
  Guide now in the note of 'General routines' section:
  https://code.google.com/p/numexpr/wiki/UsersGuide#General_routines.
  Closes #110.

* [ENH] numexpr.test() returns `TestResult` instead of None now.
  Closes #111.

* [FIX] Modulus with zero with integers no longer crashes the
  interpreter.  It nows puts a zero in the result.  Fixes #107.

* [API CLEAN] Removed `copy_args` argument of `evaluate`.  This should
  only be used by old versions of PyTables (< 3.0).

* [DOC] Documented the `optimization` and `truediv` flags of
  `evaluate` in Users Guide
  (https://code.google.com/p/numexpr/wiki/UsersGuide).

Changes from 2.0.1 to 2.1
===========================

* Dropped compatibility with Python < 2.6.

* Improve compatibiity with Python 3:

  - switch from PyString to PyBytes API (requires Python >= 2.6).
  - fixed incompatibilities regarding the int/long API
  - use the Py_TYPE macro
  - use the PyVarObject_HEAD_INIT macro instead of PyObject_HEAD_INIT

* Fixed several issues with different platforms not supporting
  multithreading or subprocess properly (see tickets #75 and #77).

* Now, when trying to use pure Python boolean operators, 'and',
  'or' and 'not', an error is issued suggesting that '&', '|' and
  '~' should be used instead (fixes #24).

Changes from 2.0 to 2.0.1
=========================

* Added compatibility with Python 2.5 (2.4 is definitely not supported
  anymore).

* `numexpr.evaluate` is fully documented now, in particular the new
  `out`, `order` and `casting` parameters.

* Reduction operations are fully documented now.

* Negative axis in reductions are not supported (they have never been
  actually), and a `ValueError` will be raised if they are used.


Changes from 1.x series to 2.0
==============================

- Added support for the new iterator object in NumPy 1.6 and later.

  This allows for better performance with operations that implies
  broadcast operations, fortran-ordered or non-native byte orderings.
  Performance for other scenarios is preserved (except for very small
  arrays).

- Division in numexpr is consistent now with Python/NumPy.  Fixes #22
  and #58.

- Constants like "2." or "2.0" must be evaluated as float, not
  integer.  Fixes #59.

- `evaluate()` function has received a new parameter `out` for storing
  the result in already allocated arrays.  This is very useful when
  dealing with large arrays, and a allocating new space for keeping
  the result is not acceptable.  Closes #56.

- Maximum number of threads raised from 256 to 4096.  Machines with a
  higher number of cores will still be able to import numexpr, but
  limited to 4096 (which is an absurdly high number already).

From the changelog since 0.17.1

15-07-2013 Darkice 1.2 released
    o Issue #75: Added Ogg/Opus support. Patch by Doug Kelly
	[email protected]
    o Fix 'Ring Ruffer' reports.
      - Increased buffer for jack to 5 seconds
      - prevent darkice termination by jack, report no fatal problem when we
        have a ringbuffer overflow, can happen during startup
        If we can not handle input audio fast enough we just ignore the buffer
        and skip it, and just report it.
      - new multithreaded connector code, now handles encoders in parallel
        and does not spin waiting, cpu load will be very much lower now
        Codes uses 2 condition variables to report data availability and
        consumer thread availability
      - Hopes are that glitching reports will be a thing of the past
      - minor compiler warnings fixed

Previous release notes seem to be lost - the build structure changed, and:

  Both the main configuration file and the filter group configuration
  file(s) have changed since the last stable release.  If you try
  to re-use the configuration from an existing copy of 2.8.0.6 or
  earlier, the daemon will not start.  On the other hand, list
  files (phrase lists, domain lists, etc.) have not changed format,
  and should largely "just work".  There have been improvements to
  the default list files, though, so again it is recommended that
  you start from the new version and re-do any customisations.

---
3.7
---

* Gnome keyring no longer relies on the GNOME_KEYRING_CONTROL environment
  variable.
* Issue #140: Restore compatibility for older versions of PyWin32.

---
3.6
---

* `Pull Request #1 (github) <https://github.com/jaraco/keyring/pull/1>`_:
  Add support for packages that wish to bundle keyring by using relative
  imports throughout.

---
3.5
---

* Issue #49: Give the backend priorities a 1.5 multiplier bump when an
  XDG_CURRENT_DESKTOP environment variable matches the keyring's target
  environment.
* Issue #99: Clarified documentation on location of config and data files.
  Prepared the code base to treat the two differently on Unix-based systems.
  For now, the behavior is unchanged.

---
3.4
---

* Extracted FileBacked and Encrypted base classes.
* Add a pyinstaller hook to expose backend modules. Ref #124
* Pull request #41: Use errno module instead of hardcoding error codes.
* SecretService backend: correctly handle cases when user dismissed
  the collection creation or unlock prompt.

---
3.3
---

* Pull request #40: KWallet backend will now honor the ``KDE_FULL_SESSION``
  environment variable as found on openSUSE.

-----
3.2.1
-----

* SecretService backend: use a different function to check that the
  backend is functional. The default collection may not exist, but
  the collection will remain usable in that case.

  Also, make the error message more verbose.

  Resolves https://bugs.launchpad.net/bugs/1242412.

---
3.2
---

* Issue #120: Invoke KeyringBackend.priority during load_keyring to ensure
  that any keyring loaded is actually viable (or raises an informative
  exception).

* File keyring:

   - Issue #123: fix removing items.
   - Correctly escape item name when removing.
   - Use with statement when working with files.

* Add a test for removing one item in group.

* Issue #81: Added experimental support for third-party backends. See
  `keyring.core._load_library_extensions` for information on supplying
  a third-party backend.

---
3.1
---

* All code now runs natively on both Python 2 and Python 3, no 2to3 conversion
  is required.
* Testsuite: clean up, and make more use of unittest2 methods.

-----
3.0.5
-----

* Issue #114: Fix logic in pyfs detection.

-----
3.0.4
-----

* Issue #114: Fix detection of pyfs under Mercurial Demand Import.

-----
3.0.3
-----

* Simplified the implementation of ``keyring.core.load_keyring``. It now uses
  ``__import__`` instead of loading modules explicitly. The ``keyring_path``
  parameter to ``load_keyring`` is now deprecated. Callers should instead
  ensure their module is available on ``sys.path`` before calling
  ``load_keyring``. Keyring still honors ``keyring-path``. This change fixes
  Issue #113 in which the explicit module loading of keyring modules was
  breaking package-relative imports.

-----
3.0.2
-----

* Renamed ``keyring.util.platform`` to ``keyring.util.platform_``. As reported
  in Issue #112 and `mercurial_keyring #31
  <https://bitbucket.org/Mekk/mercurial_keyring/issue/31>`_ and in `Mercurial
  itself <http://bz.selenic.com/show_bug.cgi?id=4029>`_, Mercurial's Demand
  Import does not honor ``absolute_import`` directives, so it's not possible
  to have a module with the same name as another top-level module. A patch is
  in place to fix this issue upstream, but to support older Mercurial
  versions, this patch will remain for some time.

-----
3.0.1
-----

* Ensure that modules are actually imported even in Mercurial's Demand Import
  environment.

---
3.0
---

* Removed support for Python 2.5.
* Removed names in ``keyring.backend`` moved in 1.1 and previously retained
  for compatibilty.

-----
2.1.1
-----

* Restored Python 2.5 compatibility (lost in 2.0).

---
2.1
---

*  Issue #10: Added a 'store' attribute to the OS X Keyring, enabling custom
   instances of the KeyringBackend to use another store, such as the
   'internet' store. For example::

       keys = keyring.backends.OS_X.Keyring()
       keys.store = 'internet'
       keys.set_password(system, user, password)
       keys.get_password(system, user)

   The default for all instances can be set in the class::

       keyring.backends.OS_X.Keyring.store = 'internet'

*  GnomeKeyring: fix availability checks, and make sure the warning
   message from pygobject is not printed.

*  Fixes to GnomeKeyring and SecretService tests.

-----
2.0.3
-----

*  Issue #112: Backend viability/priority checks now are more aggressive about
   module presence checking, requesting ``__name__`` from imported modules to
   force the demand importer to actually attempt the import.

-----
2.0.2
-----

*  Issue #111: Windows backend isn't viable on non-Windows platforms.

-----
2.0.1
-----

*  Issue #110: Fix issues with ``Windows.RegistryKeyring``.

---
2.0
---

*  Issue #80: Prioritized backend support. The primary interface for Keyring
   backend classes has been refactored to now emit a 'priority' based on the
   current environment (operating system, libraries available, etc). These
   priorities provide an indication of the applicability of that backend for
   the current environment. Users are still welcome to specify a particular
   backend in configuration, but the default behavior should now be to select
   the most appropriate backend by default.

-----
1.6.1
-----

* Only include pytest-runner in 'setup requirements' when ptr invocation is
  indicated in the command-line (Issue #105).

---
1.6
---

*  GNOME Keyring backend:

   - Use the same attributes (``username`` / ``service``) as the SecretService
     backend uses, allow searching for old ones for compatibility.
   - Also set ``application`` attribute.
   - Correctly handle all types of errors, not only ``CANCELLED`` and ``NO_MATCH``.
   - Avoid printing warnings to stderr when GnomeKeyring is not available.

* Secret Service backend:

   - Use a better label for passwords, the same as GNOME Keyring backend uses.

---
1.5
---

*  SecretService: allow deleting items created using previous python-keyring
   versions.

   Before the switch to secretstorage, python-keyring didn't set "application"
   attribute. Now in addition to supporting searching for items without that
   attribute, python-keyring also supports deleting them.

*  Use ``secretstorage.get_default_collection`` if it's available.

   On secretstorage 1.0 or later, python-keyring now tries to create the
   default collection if it doesn't exist, instead of just raising the error.

*  Improvements for tests, including fix for Issue #102.

---
1.4
---

* Switch GnomeKeyring backend to use native libgnome-keyring via
  GObject Introspection, not the obsolete python-gnomekeyring module.

---
1.3
---

* Use the `SecretStorage library <https://pypi.python.org/pypi/SecretStorage>`_
  to implement the Secret Service backend (instead of using dbus directly).
  Now the keyring supports prompting for and deleting passwords. Fixes #69,
  #77, and #93.
* Catch `gnomekeyring.IOError` per the issue `reported in Nova client
  <https://bugs.launchpad.net/python-novaclient/+bug/1116302>`_.
* Issue #92 Added support for delete_password on Mac OS X Keychain.

-----
1.2.3
-----

* Fix for Encrypted File backend on Python 3.
* Issue #97 Improved support for PyPy.

-----
1.2.2
-----

* Fixed handling situations when user cancels kwallet dialog or denies access
  for the app.

-----
1.2.1
-----

* Fix for kwallet delete.
* Fix for OS X backend on Python 3.
* Issue #84: Fix for Google backend on Python 3 (use of raw_input not caught
  by 2to3).

---
1.2
---

* Implemented delete_password on most keyrings. Keyring 2.0 will require
  delete_password to implement a Keyring. Fixes #79.

-----
1.1.2
-----

* Issue #78: pyfilesystem backend now works on Windows.

-----
1.1.1
-----

* Fixed MANIFEST.in so .rst files are included.

---
1.1
---

This is the last build that will support installation in a pure-distutils
mode. Subsequent releases will require setuptools/distribute to install.
Python 3 installs have always had this requirement (for 2to3 install support),
but starting with the next minor release (1.2+), setuptools will be required.

Additionally, this release has made some substantial refactoring in an
attempt to modularize the backends. An attempt has been made to maintain 100%
backward-compatibility, although if your library does anything fancy with
module structure or clasess, some tweaking may be necessary. The
backward-compatible references will be removed in 2.0, so the 1.1+ releases
represent a transitional implementation which should work with both legacy
and updated module structure.

* Added a console-script 'keyring' invoking the command-line interface.
* Deprecated _ExtensionKeyring.
* Moved PasswordSetError and InitError to an `errors` module (references kept
  for backward-compatibility).
* Moved concrete backend implementations into their own modules (references
  kept for backward compatibility):

  - OSXKeychain -> backends.OS_X.Keyring
  - GnomeKeyring -> backends.Gnome.Keyring
  - SecretServiceKeyring -> backends.SecretService.Keyring
  - KDEKWallet -> backends.kwallet.Keyring
  - BasicFileKeyring -> backends.file.BaseKeyring
  - CryptedFileKeyring -> backends.file.EncryptedKeyring
  - UncryptedFileKeyring -> backends.file.PlaintextKeyring
  - Win32CryptoKeyring -> backends.Windows.EncryptedKeyring
  - WinVaultKeyring -> backends.Windows.WinVaultKeyring
  - Win32CryptoRegistry -> backends.Windows.RegistryKeyring
  - select_windows_backend -> backends.Windows.select_windows_backend
  - GoogleDocsKeyring -> backends.Google.DocsKeyring
  - Credential -> keyring.credentials.Credential
  - BaseCredential -> keyring.credentials.SimpleCredential
  - EnvironCredential -> keyring.credentials.EnvironCredential
  - GoogleEnvironCredential -> backends.Google.EnvironCredential
  - BaseKeyczarCrypter -> backends.keyczar.BaseCrypter
  - KeyczarCrypter -> backends.keyczar.Crypter
  - EnvironKeyczarCrypter -> backends.keyczar.EnvironCrypter
  - EnvironGoogleDocsKeyring -> backends.Google.KeyczarDocsKeyring
  - BasicPyfilesystemKeyring -> backends.pyfs.BasicKeyring
  - UnencryptedPyfilesystemKeyring -> backends.pyfs.PlaintextKeyring
  - EncryptedPyfilesystemKeyring -> backends.pyfs.EncryptedKeyring
  - EnvironEncryptedPyfilesystemKeyring -> backends.pyfs.KeyczarKeyring
  - MultipartKeyringWrapper -> backends.multi.MultipartKeyringWrapper

* Officially require Python 2.5 or greater (although unofficially, this
  requirement has been in place since 0.10).

---
1.0
---

This backward-incompatible release attempts to remove some cruft from the
codebase that's accumulated over the versions.

* Removed legacy file relocation support. `keyring` no longer supports loading
  configuration or file-based backends from ~. If upgrading from 0.8 or later,
  the files should already have been migrated to their new proper locations.
  If upgrading from 0.7.x or earlier, the files will have to be migrated
  manually.
* Removed CryptedFileKeyring migration support. To maintain an existing
  CryptedFileKeyring, one must first upgrade to 0.9.2 or later and access the
  keyring before upgrading to 1.0 to retain the existing keyring.
* File System backends now create files without group and world permissions.
  Fixes #67.

------
0.10.1
------

* Merged 0.9.3 to include fix for #75.

----
0.10
----

* Add support for using `Keyczar <http://www.keyczar.org/>`_ to encrypt
  keyrings. Keyczar is "an open source cryptographic toolkit designed to make
  it easier and safer for developers to use cryptography in their
  applications."
* Added support for storing keyrings on Google Docs or any other filesystem
  supported by pyfilesystem.
* Fixed issue in Gnome Keyring when unicode is passed as the service name,
  username, or password.
* Tweaked SecretService code to pass unicode to DBus, as unicode is the
  preferred format.
* Issue #71 - Fixed logic in CryptedFileKeyring.
* Unencrypted keyring file will be saved with user read/write (and not group
  or world read/write).

-----
0.9.3
-----

* Ensure migration is run when get_password is called. Fixes #75. Thanks to
  Marc Deslauriers for reporting the bug and supplying the patch.

-----
0.9.2
-----

* Keyring 0.9.1 introduced a whole different storage format for the
  CryptedFileKeyring, but this introduced some potential compatibility issues.
  This release incorporates the security updates but reverts to the INI file
  format for storage, only encrypting the passwords and leaving the service
  and usernames in plaintext. Subsequent releases may incorporate a new
  keyring to implement a whole-file encrypted version. Fixes #64.
* The CryptedFileKeyring now requires simplejson for Python 2.5 clients.

-----
0.9.1
-----

* Fix for issue where SecretServiceBackend.set_password would raise a
  UnicodeError on Python 3 or when a unicode password was provided on Python
  2.
* CryptedFileKeyring now uses PBKDF2 to derive the key from the user's
  password and a random hash. The IV is chosen randomly as well. All the
  stored passwords are encrypted at once. Any keyrings using the old format
  will be automatically converted to the new format (but will no longer be
  compatible with 0.9 and earlier). The user's password is no longer limited
  to 32 characters. PyCrypto 2.5 or greater is now required for this keyring.

---
0.9
---

* Add support for GTK 3 and secret service D-Bus. Fixes #52.
* Issue #60 - Use correct method for decoding.

-----
0.8.1
-----

* Fix regression in keyring lib on Windows XP where the LOCALAPPDATA
  environment variable is not present.

---
0.8
---

* Mac OS X keyring backend now uses subprocess calls to the `security`
  command instead of calling the API, which with the latest updates, no
  longer allows Python to invoke from a virtualenv. Fixes issue #13.
* When using file-based storage, the keyring files are no longer stored
  in the user's home directory, but are instead stored in platform-friendly
  locations (`%localappdata%\Python Keyring` on Windows and according to
  the freedesktop.org Base Dir Specification
  (`$XDG_DATA_HOME/python_keyring` or `$HOME/.local/share/python_keyring`)
  on other operating systems). This fixes #21.

*Backward Compatibility Notice*

Due to the new storage location for file-based keyrings, keyring 0.8
supports backward compatibility by automatically moving the password
files to the updated location. In general, users can upgrade to 0.8 and
continue to operate normally. Any applications that customize the storage
location or make assumptions about the storage location will need to take
this change into consideration. Additionally, after upgrading to 0.8,
it is not possible to downgrade to 0.7 without manually moving
configuration files. In 1.0, the backward compatibilty
will be removed.

-----
0.7.1
-----

* Removed non-ASCII characters from README and CHANGES docs (required by
  distutils if we're to include them in the long_description). Fixes #55.

---
0.7
---

* Python 3 is now supported. All tests now pass under Python 3.2 on
  Windows and Linux (although Linux backend support is limited). Fixes #28.
* Extension modules on Mac and Windows replaced by pure-Python ctypes
  implementations. Thanks to Jerome Laheurte.
* WinVaultKeyring now supports multiple passwords for the same service. Fixes
  #47.
* Most of the tests don't require user interaction anymore.
* Entries stored in Gnome Keyring appears now with a meaningful name if you try
  to browser your keyring (for ex. with Seahorse)
* Tests from Gnome Keyring no longer pollute the user own keyring.
* `keyring.util.escape` now accepts only unicode strings. Don't try to encode
  strings passed to it.

-----
0.6.2
-----

* fix compiling on OSX with XCode 4.0

-----
0.6.1
-----

* Gnome keyring should not be used if there is no DISPLAY or if the dbus is
  not around (https://bugs.launchpad.net/launchpadlib/+bug/752282).

---
0.6

---

* `Pull Request #1 (github) <https://github.com/jaraco/keyring/pull/1>`_:
  Add support for packages that wish to bundle keyring by using relative
  imports throughout.

---

  XDG_CURRENT_DESKTOP environment variable matches the keyring's target
  environment.
* Issue #99: Clarified documentation on location of config and data files.
  Prepared the code base to treat the two differently on Unix-based systems.

---

* Pull request #40: KWallet backend will now honor the ``KDE_FULL_SESSION``
  environment variable as found on openSUSE.

-----
3.2.1
-----

* SecretService backend: use a different function to check that the
  backend is functional. The default collection may not exist, but
  the collection will remain usable in that case.

  Also, make the error message more verbose.

  Resolves https://bugs.launchpad.net/bugs/1242412.

---
3.2

* Issue #120: Invoke KeyringBackend.priority during load_keyring to ensure
  that any keyring loaded is actually viable (or raises an informative
  exception).

* File keyring:

   - Issue #123: fix removing items.
   - Correctly escape item name when removing.
   - Use with statement when working with files.

* Add a test for removing one item in group.

* Issue #81: Added experimental support for third-party backends. See
  `keyring.core._load_library_extensions` for information on supplying
  a third-party backend.

---
3.1
---

* All code now runs natively on both Python 2 and Python 3, no 2to3 conversion
  is required.
* Testsuite: clean up, and make more use of unittest2 methods.

-----
3.0.5
-----

* Issue #114: Fix logic in pyfs detection.

-----
3.0.4
-----

* Issue #114: Fix detection of pyfs under Mercurial Demand Import.

-----
3.0.3
-----

* Simplified the implementation of ``keyring.core.load_keyring``. It now uses
  ``__import__`` instead of loading modules explicitly. The ``keyring_path``
  parameter to ``load_keyring`` is now deprecated. Callers should instead
  ensure their module is available on ``sys.path`` before calling
  ``load_keyring``. Keyring still honors ``keyring-path``. This change fixes
  Issue #113 in which the explicit module loading of keyring modules was
  breaking package-relative imports.

-----
3.0.2
-----

* Renamed ``keyring.util.platform`` to ``keyring.util.platform_``. As reported
  in Issue #112 and `mercurial_keyring #31
  <https://bitbucket.org/Mekk/mercurial_keyring/issue/31>`_ and in `Mercurial
  itself <http://bz.selenic.com/show_bug.cgi?id=4029>`_, Mercurial's Demand
  Import does not honor ``absolute_import`` directives, so it's not possible
  to have a module with the same name as another top-level module. A patch is
  in place to fix this issue upstream, but to support older Mercurial
  versions, this patch will remain for some time.

-----
3.0.1
-----

* Ensure that modules are actually imported even in Mercurial's Demand Import
  environment.

---
3.0
---

* Removed support for Python 2.5.
* Removed names in ``keyring.backend`` moved in 1.1 and previously retained
  for compatibilty.

-----
2.1.1
-----

* Restored Python 2.5 compatibility (lost in 2.0).

---
2.1
---

*  Issue #10: Added a 'store' attribute to the OS X Keyring, enabling custom
   instances of the KeyringBackend to use another store, such as the
   'internet' store. For example::

       keys = keyring.backends.OS_X.Keyring()
       keys.store = 'internet'
       keys.set_password(system, user, password)
       keys.get_password(system, user)

   The default for all instances can be set in the class::

       keyring.backends.OS_X.Keyring.store = 'internet'

*  GnomeKeyring: fix availability checks, and make sure the warning
   message from pygobject is not printed.

*  Fixes to GnomeKeyring and SecretService tests.

-----
2.0.3
-----

*  Issue #112: Backend viability/priority checks now are more aggressive about
   module presence checking, requesting ``__name__`` from imported modules to
   force the demand importer to actually attempt the import.

-----
2.0.2
-----

*  Issue #111: Windows backend isn't viable on non-Windows platforms.

-----
2.0.1
-----

*  Issue #110: Fix issues with ``Windows.RegistryKeyring``.

---
2.0
---

*  Issue #80: Prioritized backend support. The primary interface for Keyring
   backend classes has been refactored to now emit a 'priority' based on the
   current environment (operating system, libraries available, etc). These
   priorities provide an indication of the applicability of that backend for
   the current environment. Users are still welcome to specify a particular
   backend in configuration, but the default behavior should now be to select
   the most appropriate backend by default.

-----
1.6.1
-----

* Only include pytest-runner in 'setup requirements' when ptr invocation is
  indicated in the command-line (Issue #105).

---
1.6
---

*  GNOME Keyring backend:

   - Use the same attributes (``username`` / ``service``) as the SecretService
     backend uses, allow searching for old ones for compatibility.
   - Also set ``application`` attribute.
   - Correctly handle all types of errors, not only ``CANCELLED`` and ``NO_MATCH``.
   - Avoid printing warnings to stderr when GnomeKeyring is not available.

* Secret Service backend:

   - Use a better label for passwords, the same as GNOME Keyring backend uses.

---
1.5
---

*  SecretService: allow deleting items created using previous python-keyring
   versions.

   Before the switch to secretstorage, python-keyring didn't set "application"
   attribute. Now in addition to supporting searching for items without that
   attribute, python-keyring also supports deleting them.

*  Use ``secretstorage.get_default_collection`` if it's available.

   On secretstorage 1.0 or later, python-keyring now tries to create the
   default collection if it doesn't exist, instead of just raising the error.

*  Improvements for tests, including fix for Issue #102.

---
1.4
---

* Switch GnomeKeyring backend to use native libgnome-keyring via
  GObject Introspection, not the obsolete python-gnomekeyring module.

---
1.3
---

* Use the `SecretStorage library <https://pypi.python.org/pypi/SecretStorage>`_
  to implement the Secret Service backend (instead of using dbus directly).
  Now the keyring supports prompting for and deleting passwords. Fixes #69,
  #77, and #93.
* Catch `gnomekeyring.IOError` per the issue `reported in Nova client
  <https://bugs.launchpad.net/python-novaclient/+bug/1116302>`_.
* Issue #92 Added support for delete_password on Mac OS X Keychain.

-----
1.2.3
-----

* Fix for Encrypted File backend on Python 3.
* Issue #97 Improved support for PyPy.

-----
1.2.2
-----

* Fixed handling situations when user cancels kwallet dialog or denies access
  for the app.

-----
1.2.1
-----

* Fix for kwallet delete.
* Fix for OS X backend on Python 3.
* Issue #84: Fix for Google backend on Python 3 (use of raw_input not caught
  by 2to3).

---
1.2
---

* Implemented delete_password on most keyrings. Keyring 2.0 will require
  delete_password to implement a Keyring. Fixes #79.

-----
1.1.2
-----

* Issue #78: pyfilesystem backend now works on Windows.

-----
1.1.1
-----

* Fixed MANIFEST.in so .rst files are included.

---
1.1

This is the last build that will support installation in a pure-distutils
mode. Subsequent releases will require setuptools/distribute to install.
Python 3 installs have always had this requirement (for 2to3 install support),
but starting with the next minor release (1.2+), setuptools will be required.

Additionally, this release has made some substantial refactoring in an
attempt to modularize the backends. An attempt has been made to maintain 100%
backward-compatibility, although if your library does anything fancy with
module structure or clasess, some tweaking may be necessary. The
backward-compatible references will be removed in 2.0, so the 1.1+ releases
represent a transitional implementation which should work with both legacy
and updated module structure.

* Added a console-script 'keyring' invoking the command-line interface.
* Deprecated _ExtensionKeyring.
* Moved PasswordSetError and InitError to an `errors` module (references kept
  for backward-compatibility).
* Moved concrete backend implementations into their own modules (references
  kept for backward compatibility):

  - OSXKeychain -> backends.OS_X.Keyring
  - GnomeKeyring -> backends.Gnome.Keyring
  - SecretServiceKeyring -> backends.SecretService.Keyring
  - KDEKWallet -> backends.kwallet.Keyring
  - BasicFileKeyring -> backends.file.BaseKeyring

  - EnvironEncryptedPyfilesystemKeyring -> backends.pyfs.KeyczarKeyring
  - MultipartKeyringWrapper -> backends.multi.MultipartKeyringWrapper

* Officially require Python 2.5 or greater (although unofficially, this
  requirement has been in place since 0.10).

---
1.0
---

This backward-incompatible release attempts to remove some cruft from the
codebase that's accumulated over the versions.

* Removed legacy file relocation support. `keyring` no longer supports loading
  configuration or file-based backends from ~. If upgrading from 0.8 or later,
  the files should already have been migrated to their new proper locations.
  If upgrading from 0.7.x or earlier, the files will have to be migrated
  manually.
* Removed CryptedFileKeyring migration support. To maintain an existing
  CryptedFileKeyring, one must first upgrade to 0.9.2 or later and access the
  keyring before upgrading to 1.0 to retain the existing keyring.
* File System backends now create files without group and world permissions.
  Fixes #67.

------
0.10.1
------

* Merged 0.9.3 to include fix for #75.

----
0.10
----

* Add support for using `Keyczar <http://www.keyczar.org/>`_ to encrypt
  keyrings. Keyczar is "an open source cryptographic toolkit designed to make
  it easier and safer for developers to use cryptography in their
  applications."
* Added support for storing keyrings on Google Docs or any other filesystem
  supported by pyfilesystem.
* Fixed issue in Gnome Keyring when unicode is passed as the service name,
  username, or password.
* Tweaked SecretService code to pass unicode to DBus, as unicode is the
  preferred format.
* Issue #71 - Fixed logic in CryptedFileKeyring.
* Unencrypted keyring file will be saved with user read/write (and not group
  or world read/write).

-----
0.9.3
-----

* Ensure migration is run when get_password is called. Fixes #75. Thanks to
  Marc Deslauriers for reporting the bug and supplying the patch.

-----
0.9.2
-----

* Keyring 0.9.1 introduced a whole different storage format for the
  CryptedFileKeyring, but this introduced some potential compatibility issues.
  This release incorporates the security updates but reverts to the INI file
  format for storage, only encrypting the passwords and leaving the service
  and usernames in plaintext. Subsequent releases may incorporate a new
  keyring to implement a whole-file encrypted version. Fixes #64.
* The CryptedFileKeyring now requires simplejson for Python 2.5 clients.

-----
0.9.1
-----

* Fix for issue where SecretServiceBackend.set_password would raise a
  UnicodeError on Python 3 or when a unicode password was provided on Python
  2.
* CryptedFileKeyring now uses PBKDF2 to derive the key from the user's
  password and a random hash. The IV is chosen randomly as well. All the
  stored passwords are encrypted at once. Any keyrings using the old format
  will be automatically converted to the new format (but will no longer be
  compatible with 0.9 and earlier). The user's password is no longer limited
  to 32 characters. PyCrypto 2.5 or greater is now required for this keyring.

---
0.9
---

* Add support for GTK 3 and secret service D-Bus. Fixes #52.
* Issue #60 - Use correct method for decoding.

-----
0.8.1
-----

* Fix regression in keyring lib on Windows XP where the LOCALAPPDATA
  environment variable is not present.

---
0.8
---

* Mac OS X keyring backend now uses subprocess calls to the `security`
  command instead of calling the API, which with the latest updates, no
  longer allows Python to invoke from a virtualenv. Fixes issue #13.
* When using file-based storage, the keyring files are no longer stored
  in the user's home directory, but are instead stored in platform-friendly
  locations (`%localappdata%\Python Keyring` on Windows and according to
  the freedesktop.org Base Dir Specification
  (`$XDG_DATA_HOME/python_keyring` or `$HOME/.local/share/python_keyring`)
  on other operating systems). This fixes #21.

*Backward Compatibility Notice*

Due to the new storage location for file-based keyrings, keyring 0.8
supports backward compatibility by automatically moving the password
files to the updated location. In general, users can upgrade to 0.8 and
continue to operate normally. Any applications that customize the storage
location or make assumptions about the storage location will need to take
this change into consideration. Additionally, after upgrading to 0.8,
it is not possible to downgrade to 0.7 without manually moving
configuration files. In 1.0, the backward compatibilty
will be removed.

-----
0.7.1
-----

* Removed non-ASCII characters from README and CHANGES docs (required by
  distutils if we're to include them in the long_description). Fixes #55.

---
0.7
---

* Python 3 is now supported. All tests now pass under Python 3.2 on
  Windows and Linux (although Linux backend support is limited). Fixes #28.
* Extension modules on Mac and Windows replaced by pure-Python ctypes
  implementations. Thanks to Jerome Laheurte.
* WinVaultKeyring now supports multiple passwords for the same service. Fixes
  #47.
* Most of the tests don't require user interaction anymore.
* Entries stored in Gnome Keyring appears now with a meaningful name if you try
  to browser your keyring (for ex. with Seahorse)
* Tests from Gnome Keyring no longer pollute the user own keyring.
* `keyring.util.escape` now accepts only unicode strings. Don't try to encode
  strings passed to it.

-----
0.6.2
-----

* fix compiling on OSX with XCode 4.0

-----
0.6.1
-----

* Gnome keyring should not be used if there is no DISPLAY or if the dbus is
  not around (https://bugs.launchpad.net/launchpadlib/+bug/752282).

---
0.6
---

* Added `keyring.http` for facilitating HTTP Auth using keyring.

* Add a utility to access the keyring from the command line.

- Adjusted documentation to reflect possibly counter-intuitive properties of
  RFC-5545-compliant rrules, and other documentation improvements in the rrule
  module (gh issue #105, gh issue #149 - pointer to the solution by @phep,
  pr #213).


Version 2.5.0
-------------
- Updated zoneinfo to 2016a
- zoneinfo_metadata file version increased to 2.0 - the updated updatezinfo.py
  script will work with older zoneinfo_metadata.json files, but new metadata
  files will not work with older updatezinfo.py versions. Additionally, we have
  started hosting our own mirror of the Olson databases on a github pages
  site (https://dateutil.github.io/tzdata/) (gh pr #183)
- dateutil zoneinfo tarballs now contain the full zoneinfo_metadata file used
  to generate them. (gh issue #27, gh pr #85)
- relativedelta can now be safely subclassed without derived objects reverting
  to base relativedelta objects as a result of arithmetic operations.
  (lp:1010199, gh issue #44, pr #49)
- relativedelta 'weeks' parameter can now be set and retrieved as a property of
  relativedelta instances. (lp: 727525, gh issue #45, pr #49)
- relativedelta now explicitly supports fractional relative weeks, days, hours,
  minutes and seconds. Fractional values in absolute parameters (year, day, etc)
  are now deprecated. (gh issue #40, pr #190)
- relativedelta objects previously did not use microseconds to determine of two
  relativedelta objects were equal. This oversight has been corrected.
  Contributed by @elprans (gh pr #113)
- rrule now has an xafter() method for retrieving multiple recurrences after a
  specified date. (gh pr #38)
- str(rrule) now returns an RFC2445-compliant rrule string, contributed by
  @schinckel and @armicron (lp:1406305, gh issue #47, prs #50, #62 and #160)
- rrule performance under certain conditions has been significantly improved
  thanks to a patch contributed by @dekoza, based on an article by Brian Beck
  (@exogen) (gh pr #136)
- The use of both the 'until' and 'count' parameters is now deprecated as
  inconsistent with RFC2445 (gh pr #62, #185)
- Parsing an empty string will now raise a ValueError, rather than returning the
  datetime passed to the 'default' parameter. (gh issue #78, pr #187)
- tzwinlocal objects now have a meaningful repr() and str() implementation
  (gh issue #148, prs #184 and #186)
- Added equality logic for tzwin and tzwinlocal objects. (gh issue #151,
  pr #180, #184)
- Added some flexibility in subclassing timelex, and switched the default
  behavior over to using string methods rather than comparing against a fixed
  list. (gh pr #122, #139)
- An issue causing tzstr() to crash on Python 2.x was fixed. (lp: 1331576,
  gh issue #51, pr #55)
- An issue with string encoding causing exceptions under certain circumstances
  when tzname() is called was fixed. (gh issue #60, #74, pr #75)
- Parser issue where calling parse() on dates with no day specified when the
  day of the month in the default datetime (which is "today" if unspecified) is
  greater than the number of days in the parsed month was fixed (this issue
  tended to crop up between the 29th and 31st of the month, for obvious reasons)
  (canonical gh issue #25, pr #30, #191)
- Fixed parser issue causing fuzzy_with_tokens to raise an unexpected exception
  in certain circumstances. Contributed by @MichaelAquilina (gh pr #91)
- Fixed parser issue where years > 100 AD were incorrectly parsed. Contributed
  by @Bachmann1234 (gh pr #130)
- Fixed parser issue where commas were not a valid separator between seconds
  and microseconds, preventing parsing of ISO 8601 dates. Contributed by
  @RyansS (gh issue #28, pr #106)
- Fixed issue with tzwin encoding in locales with non-Latin alphabets
  (gh issue #92, pr #98)
- Fixed an issue where tzwin was not being properly imported on Windows.
  Contributed by @labrys. (gh pr #134)
- Fixed a problem causing issues importing zoneinfo in certain circumstances.
  Issue and solution contributed by @alexxv (gh issue #97, pr #99)
- Fixed an issue where dateutil timezones were not compatible with basic time
  objects. One of many, many timezone related issues contributed and tested by
  @labrys. (gh issue #132, pr #181)
- Fixed issue where tzwinlocal had an invalid utcoffset. (gh issue #135,
  pr #141, #142)
- Fixed issue with tzwin and tzwinlocal where DST transitions were incorrectly
  parsed from the registry. (gh issue #143, pr #178)
- updatezinfo.py no longer suppresses certain OSErrors. Contributed by @bjamesv
  (gh pr #164)
- An issue that arose when timezone locale changes during runtime has been
  fixed by @carlosxl and @mjschultz (gh issue #100, prs #107, #109)
- Python 3.5 was added to the supported platforms in the metadata (@tacaswell
  gh pr #159) and the test suites (@moreati gh pr #117).
- An issue with tox failing without unittest2 installed in Python 2.6 was fixed
  by @moreati (gh pr #115)
- Several deprecated functions were replaced in the tests by @moreati
  (gh pr #116)
- Improved the logic in Travis and Appveyor to alleviate issues where builds
  were failing due to connection issues when downloading the IANA timezone
  files. In addition to adding our own mirror for the files (gh pr #183), the
  download is now retried a number of times (with a delay) (gh pr #177)
- Many failing doctests were fixed by @moreati. (gh pr #120)
- Many fixes to the documentation (gh pr #103, gh pr #87 from @radarhere,
  gh pr #154 from @gpoesia, gh pr #156 from @awsum, gh pr #168 from @ja8zyjits)
- Added a code coverage tool to the CI to help improve the library. (gh pr #182)
- We now have a mailing list - [email protected], graciously hosted by
  Python.org.


Version 2.4.2
-------------
- Updated zoneinfo to 2015b.
- Fixed issue with parsing of tzstr on Python 2.7.x; tzstr will now be decoded
  if not a unicode type. gh #51 (lp:1331576), gh pr #55.
- Fix a parser issue where AM and PM tokens were showing up in fuzzy date
  stamps, triggering inappropriate errors. gh #56 (lp: 1428895), gh pr #63.
- Missing function "setcachesize" removed from zoneinfo __all__ list by @RyansS,
  fixing an issue with wildcard imports of dateutil.zoneinfo. (gh pr #66).
- (PyPi only) Fix an issue with source distributions not including the test
  suite.


Version 2.4.1
-------------

- Added explicit check for valid hours if AM/PM is specified in parser.
  (gh pr #22, issue #21)
- Fix bug in rrule introduced in 2.4.0 where byweekday parameter was not
  handled properly. (gh pr #35, issue #34)
- Fix error where parser allowed some invalid dates, overwriting existing hours
  with the last 2-digit number in the string. (gh pr #32, issue #31)
- Fix and add test for Python 2.x compatibility with boolean checking of
  relativedelta objects. Implemented by @nimasmi (gh pr #43) and Cédric Krier
  (lp: 1035038)
- Replaced parse() calls with explicit datetime objects in unit tests unrelated
  to parser. (gh pr #36)
- Changed private _byxxx from sets to sorted tuples and fixed one currently
  unreachable bug in _construct_byset. (gh pr #54)
- Additional documentation for parser (gh pr #29, #33, #41) and rrule.
- Formatting fixes to documentation of rrule and README.rst.
- Updated zoneinfo to 2015a.
