gcc should accept and ignore -fomit-frame-pointer instead of omitting the frame pointer. This option has no positive benefits and causes the resulting binaries to be impossible to debug. Since many automated build systems apply this argument even when the end user has not consciously chosen to create an undebuggable binary, the sensible thing to do is to simply ignore the option.

    5. On the encoding is 'mac-roman' on Darwin, use UTF-8 as 'mac-roman' was
       a bug on older Python releases.

    On a side note, it would seem that the encoding only matters for when SVN
    does not yet support ``--xml`` and when getting repository and svn version
    numbers. The ``--xml`` technique should yield UTF-8 according to some
    messages on the SVN mailing lists. So if the version numbers are always
    7-bit ASCII clean, it may be best to only support the file parsing methods
    for legacy SVN releases and support for SVN without the subprocess command
    would simple go away as support for the older SVNs does.

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)

  (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)

       the encoding.
    4. On the event of an error or unknown codec, revert to fallbacks
       (UTF-8 on Darwin, ASCII on everything else).
    5. On the encoding is 'mac-roman' on Darwin, use UTF-8 as 'mac-roman' was
       a bug on older Python releases.

    On a side note, it would seem that the encoding only matters for when SVN
    does not yet support ``--xml`` and when getting repository and svn version
    numbers. The ``--xml`` technique should yield UTF-8 according to some
    messages on the SVN mailing lists. So if the version numbers are always
    7-bit ASCII clean, it may be best to only support the file parsing methods
    for legacy SVN releases and support for SVN without the subprocess command
    would simple go away as support for the older SVNs does.

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)

  (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)

The update request to 1.0.18 from doc/TODO ([but actually obsolete,
switch to libusb]) has been done.

(upstream)
  Update 1.0.11 to 1.0.18
For detailed information about the changes below, please see the git log or
visit: http://log.libusbx.org

2014-01-25: v1.0.18 *FINAL RELEASE*
* Last release of libusbx, as the project is merging back again with libusb.
  As a result, continuation of the project will now occur from the following:
  o Main site:          http://libusb.info
  o Git repository:     https://github.com/libusb/libusb
  o SF repository:      https://sourceforge.net/projects/libusb/
  o Mailing list:       [email protected] (registration req.)

* Multiple OS X improvements (broken compilation, SIGFPE, 64bit support)

2013-09-06: v1.0.17
* Hotplug callbacks now always get passed a libusb_context, even if it is
  the default context. Previously NULL would be passed for the default context,
  but since the first context created is the default context, and most apps
  use only 1 context, this meant that apps explicitly creating a context would
  still get passed NULL
* Android: Add .mk files to build with the Android NDK
* Darwin: Add Xcode project
* Darwin: Fix crash on unplug (#121)
* Linux: Fix hang (deadlock) on libusb_exit
* Linux: Fix libusbx build failure with --disable-udev (#124)

* OpenBSD: Update OpenBSD backend with support for control transfers to
  non-ugen(4) devices and make get_configuration() no longer generate I/O.
  Note that using this libusbx version on OpenBSD requires using
  OpenBSD 5.3-current or later. Users of older OpenBSD versions are advised
  to stay with the libusb shipped with OpenBSD (mpi)
* Windows: fix libusb_dll_2010.vcxproj link errors (#129)
* Various other bug fixes and improvements
The (#xx) numbers are libusbx issue numbers, see ie:
https://github.com/libusbx/libusbx/issues/121

* Darwin: make libusb_reset reenumerate device on descriptors change (#89)
* Darwin: add support for the LIBUSB_TRANSFER_ADD_ZERO_PACKET flag (#91)
* Darwin: add a device cache (#112, #114)
* Examples: Add sam3u_benchmark isochronous example by Harald Welte (#109)
* Many other bug fixes and improvements

2012-09-26: v1.0.14
* Reverts the previous API change with regards to bMaxPower.
  If this doesn't matter to you, you are encouraged to keep using v1.0.13,
  as it will use the same attribute as v2.0, to be released soon.
* Note that LIBUSBX_API_VERSION is *decreased* to 0x010000FF and the previous
  guidelines with regards to concurrent use of MaxPower/bMaxPower still apply.

2012-09-20: v1.0.13
* [MAJOR] Fix a typo in the API with struct libusb_config_descriptor where
  MaxPower was used instead of bMaxPower, as defined in the specs. If your
  application was accessing the MaxPower attribute, and you need to maintain
  compatibility with libusb or older versions, see APPENDIX A below.

* Add toggleable debug, using libusb_set_debug() or the LIBUSB_DEBUG environment variable
* Define log levels in libusb.h and set timestamp origin to first libusb_init() call
* All logging is now sent to to stderr (info was sent to stdout previously)
* Update log messages severity and avoid polluting log output on OS-X
* Add HID driver support on Windows
* Enable interchangeability of MSVC and MinGW DLLs

Update DEPENDS
Add test target

Upstream changes:
2015-03-14 -- 1.4.3

    * Remove three warnings: star-args, abstract-class-little-used,
      abstract-class-not-used. These warnings don't add any real value
      and they don't imply errors or problems in the code.

    * Added a new option for controlling the peephole optimizer in astroid.
      The option ``--optimize-ast`` will control the peephole optimizer,
      which is used to optimize a couple of AST subtrees. The current problem
      solved by the peephole optimizer is when multiple joined strings,
      with the addition operator, are encountered. If the numbers of such
      strings is high enough, Pylint will then fail with a maximum recursion
      depth exceeded error, due to its visitor architecture. The peephole
      just transforms such calls, if it can, into the final resulting string
      and this exhibit a problem, because the visit_binop method stops being
      called (in the optimized AST it will be a Const node).


2015-03-11 -- 1.4.2

    * Don't require a docstring for empty modules. Closes issue #261.

    * Fix a false positive with `too-few-format-args` string warning,
      emitted when the string format contained a normal positional
      argument ('{0}'), mixed with a positional argument which did
      an attribute access ('{0.__class__}').
      Closes issue #463.

    * Take in account all the methods from the ancestors
      when checking for too-few-public-methods. Closes issue #471.

    * Catch enchant errors and emit 'invalid-characters-in-docstring'
      when checking for spelling errors. Closes issue #469.

    * Use all the inferred statements for the super-init-not-called
      check. Closes issue #389.

    * Add a new warning, 'unichr-builtin', emitted by the Python 3
      porting checker, when the unichr builtin is found. Closes issue #472.

    * Add a new warning, 'intern-builtin', emitted by the Python 3
      porting checker, when the intern builtin is found. Closes issue #473.

    * Add support for editable installations.

    * The HTML output accepts the `--msg-template` option. Patch by
      Dan Goldsmith.

    * Add 'map-builtin-not-iterating' (replacing 'implicit-map-evaluation'),
      'zip-builtin-not-iterating', 'range-builtin-not-iterating', and
      'filter-builtin-not-iterating' which are emitted by `--py3k` when the
      appropriate built-in is not used in an iterating context (semantics
      taken from 2to3).

    * Add a new warning, 'unidiomatic-typecheck', emitted when an explicit
      typecheck uses type() instead of isinstance(). For example,
      `type(x) == Y` instead of `isinstance(x, Y)`. Patch by Chris Rebert.
      Closes issue #299.

    * Add support for combining the Python 3 checker mode with the --jobs
      flag (--py3k and --jobs). Closes issue #467.

    * Add a new warning for the Python 3 porting checker, 'using-cmp-argument',
      emitted when the `cmp` argument for the `list.sort` or `sorted builtin`
      is encountered.

    * Make the --py3k flag commutative with the -E flag. Also, this patch
      fixes the leaks of error messages from the Python 3 checker when
      the errors mode was activated. Closes issue #437.


2015-01-16 -- 1.4.1

    * Look only in the current function's scope for bad-super-call.
      Closes issue #403.

    * Check the return of properties when checking for not-callable.
      Closes issue #406.

    * Warn about using the input() or round() built-ins for Python 3.
      Closes issue #411.

    * Proper abstract method lookup while checking for
      abstract-class-instantiated. Closes issue #401.

    * Use a mro traversal for finding abstract methods. Closes issue #415.

    * Fix a false positive with catching-non-exception and tuples of
      exceptions.

    * Fix a false negative with raising-non-exception, when the raise used
      an uninferrable exception context.

    * Fix a false positive on Python 2 for raising-bad-type, when
      raising tuples in the form 'raise (ZeroDivisionError, None)'.

    * Fix a false positive with invalid-slots-objects, where the slot entry
      was an unicode string on Python 2. Closes issue #421.

    * Add a new warning, 'redundant-unittest-assert', emitted when using
      unittest's methods assertTrue and assertFalse with constant value
      as argument. Patch by Vlad Temian.

    * Add a new JSON reporter, usable through -f flag.

    * Add the method names for the 'signature-differs' and 'argument-differs'
      warnings. Closes issue #433.

    * Don't compile test files when installing.

    * Fix a crash which occurred when using multiple jobs and the files
      given as argument didn't exist at all.


2014-11-23 -- 1.4.0

    * Added new options for controlling the loading of C extensions.
      By default, only C extensions from the stdlib will be loaded
      into the active Python interpreter for inspection, because they
      can run arbitrary code on import. The option
      `--extension-pkg-whitelist` can be used to specify modules
      or packages that are safe to load.

    * Change default max-line-length to 100 rather than 80

    * Drop BaseRawChecker class which were only there for backward
      compat for a while now

    * Don't try to analyze string formatting with objects coming from
      function arguments. Closes issue #373.

    * Port source code to be Python 2/3 compatible. This drops the
      need for 2to3, but does drop support for Python 2.5.

    * Each message now comes with a confidence level attached, and
      can be filtered base on this level. This allows to filter out
      all messages that were emitted even though an inference failure
      happened during checking.

    * Improved presenting unused-import message. Closes issue #293.

    * Add new checker for finding spelling errors. New messages:
      wrong-spelling-in-comment, wrong-spelling-in-docstring.
      New options: spelling-dict, spelling-ignore-words.

    * Add new '-j' option for running checks in sub-processes.

    * Added new checks for line endings if they are mixed (LF vs CRLF)
      or if they are not as expected. New messages: mixed-line-endings,
      unexpected-line-ending-format. New option: expected-line-ending-format.

    * 'dangerous-default-value' no longer evaluates the value of the arguments,
      which could result in long error messages or sensitive data being leaked.
      Closes issue #282

    * Fix a false positive with string formatting checker, when
      encountering a string which uses only position-based arguments.
      Closes issue #285.

    * Fix a false positive with string formatting checker, when using
      keyword argument packing. Closes issue #288.

    * Proper handle class level scope for lambdas.

    * Handle 'too-few-format-args' or 'too-many-format-args' for format
      strings with both named and positional fields. Closes issue #286.

    * Analyze only strings by the string format checker. Closes issue #287.

    * Properly handle nested format string fields. Closes issue #294.

    * Don't emit 'attribute-defined-outside-init' if the attribute
      was set by a function call in a defining method. Closes issue #192.

    * Properly handle unicode format strings for Python 2.
      Closes issue #296.

    * Don't emit 'import-error' if an import was protected by a try-except,
      which excepted ImportError.

    * Fix an 'unused-import' false positive, when the error was emitted
      for all the members imported with 'from import' form.
      Closes issue #304.

    * Don't emit 'invalid-name' when assigning a name in an
      ImportError handler. Closes issue #302.

    * Don't count branches from nested functions.

    * Fix a false positive with 'too-few-format-args', when the format
      strings contains duplicate manual position arguments.
      Closes issue #310.

    * fixme regex handles comments without spaces after the hash.
      Closes issue #311.

    * Don't emit 'unused-import' when a special object is imported
      (__all__, __doc__ etc.). Closes issue #309.

    * Look in the metaclass, if defined, for members not found in the current
      class. Closes issue #306.

    * Don't emit 'protected-access' if the attribute is accessed using
      a property defined at the class level.

    * Detect calls of the parent's __init__, through a binded super() call.

    * Check that a class has an explicitly defined metaclass before
      emitting 'old-style-class' for Python 2.

    * Emit 'catching-non-exception' for non-class nodes. Closes issue #303.

    * Order of reporting is consistent.

    * Add a new warning, 'boolean-datetime', emitted when an instance
      of 'datetime.time' is used in a boolean context. Closes issue #239.

    * Fix a crash which ocurred while checking for 'method-hidden',
      when the parent frame was something different than a function.

    * Generate html output for missing files. Closes issue #320.

    * Fix a false positive with 'too-many-format-args', when the format
      string contains mixed attribute access arguments and manual
      fields. Closes issue #322.

    * Extend the cases where 'undefined-variable' and 'used-before-assignment'
      can be detected. Closes issue #291.

    * Add support for customising callback identifiers, by adding a new
      '--callbacks' command line option. Closes issue #326.

    * Add a new warning, 'logging-format-interpolation', emitted when .format()
      string interpolation is used within logging function calls.

    * Don't emit 'unbalanced-tuple-unpacking' when the rhs of the assignment
      is a variable length argument. Closes issue #329.

    * Add a new warning, 'inherit-non-class', emitted when a class inherits
      from something which is not a class. Closes issue #331.

    * Fix another false positives with 'undefined-variable', where the variable
      can be found as a class assignment and used in a function annotation.
      Closes issue #342.

    * Handle assignment of the string format method to a variable.
      Closes issue #351.

    * Support wheel packaging format for PyPi. Closes issue #334.

    * Check that various built-ins that do not exist in Python 3 are not
      used: apply, basestring, buffer, cmp, coerce, execfile, file, long
      raw_input, reduce, StandardError, unicode, reload and xrange.

    * Warn for magic methods which are not used in any way in Python 3:
      __coerce__, __delslice__, __getslice__, __setslice__, __cmp__,
      __oct__, __nonzero__ and __hex__.

    * Don't emit 'assigning-non-slot' when the assignment is for a property.

    * Report the percentage of all messages, not just for errors and warnings.
      Closes issue #319.

    * 'too-many-public-methods' is reported only for methods defined in a class,
      not in its ancestors. Closes issue #248.

    * 'too-many-lines' disable pragma can be located on any line, not only the

      mode will disable all other checkers and will emit warnings and
      errors for constructs which are invalid or removed in Python 3.

    * Add 'old-octal-literal' to Python 3 porting checker, emitted when
      encountering octals with the old syntax.

    * Add 'implicit-map-evaluation' to Python 3 porting checker, emitted
      when encountering the use of map builtin, without explicit evaluation.

* Reverts the previous API change with regards to bMaxPower.
  If this doesn't matter to you, you are encouraged to keep using v1.0.13,
  as it will use the same attribute as v2.0, to be released soon.
* Note that LIBUSB_API_VERSION is *decreased* to 0x010000FF and the previous
  guidelines with regards to concurrent use of MaxPower/bMaxPower still apply.

2012-09-20: v1.0.13
* [MAJOR] Fix a typo in the API with struct libusb_config_descriptor where

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
APPENDIX A - How to maintain code compatibility with versions of libusb and
libusb that use MaxPower:

If you must to maintain compatibility with versions of the library that aren't
using the bMaxPower attribute in struct libusb_config_descriptor, the
recommended way is to use the new LIBUSB_API_VERSION macro with an #ifdef.
For instance, if your code was written as follows:

  if (dev->config[0].MaxPower < 250)

Then you should modify it to have:

#if defined(LIBUSB_API_VERSION) && (LIBUSB_API_VERSION >= 0x01000100)
  if (dev->config[0].bMaxPower < 250)
#else
  if (dev->config[0].MaxPower < 250)
#endif

Fix CPU detection patch while here.

Changes from 2.5.2 to 2.6.0
===========================

- Introduced a new re_evaluate() function for re-evaluating the
  previous executed array expression without any check.  This is meant
  for accelerating loops that are re-evaluating the same expression
  repeatedly without changing anything else than the operands.  If
  unsure, use evaluate() which is safer.

- The BLOCK_SIZE1 and BLOCK_SIZE2 constants have been re-checked in
  order to find a value maximizing most of the benchmarks in bench/
  directory.  The new values (8192 and 16 respectively) give somewhat
  better results (~5%) overall.  The CPU used for fine tuning is a
  relatively new Haswell processor (E3-1240 v3).

- The '--name' flag for `setup.py` returning the name of the package
  is honored now (issue #215).


Changes from 2.5.1 to 2.5.2
===========================

- conj() and abs() actually added as VML-powered functions, preventing
  the same problems than log10() before (PR #212).  Thanks to Tom Kooij
  for the fix!


Changes from 2.5 to 2.5.1
=========================

- Fix for log10() and conj() functions.  These produced wrong results
  when numexpr was compiled with Intel's MKL (which is a popular build
  since Anaconda ships it by default) and non-contiguous data (issue
  #210).  Thanks to Arne de Laat and Tom Kooij for reporting and
  providing a nice test unit.

- Fix that allows numexpr-powered apps to be profiled with pympler.
  Thanks to @nbecker.


Changes from 2.4.6 to 2.5
=========================

- Added locking for allowing the use of numexpr in multi-threaded
  callers (this does not prevent numexpr to use multiple cores
  simultaneously).  (PR #199, Antoine Pitrou, PR #200, Jenn Olsen).

- Added new min() and max() functions (PR #195, CJ Carey).


Changes from 2.4.5 to 2.4.6
===========================

- Fixed some UserWarnings in Solaris (PR #189, Graham Jones).

- Better handling of MSVC defines. (#168, Francesc Alted).


Changes from 2.4.4 to 2.4.5
===========================

- Undone a 'fix' for a harmless data race.  (#185 Benedikt Reinartz,
  Francesc Alted).

- Ignore NumPy warnings (overflow/underflow, divide by zero and
  others) that only show up in Python3.  Masking these warnings in
  tests is fine because all the results are checked to be
  valid. (#183, Francesc Alted).


Changes from 2.4.3 to 2.4.4
===========================

- Fix bad #ifdef for including stdint on Windows (PR #186, Mike Sarahan).


Changes from 2.4.3 to 2.4.4
===========================

* Honor OMP_NUM_THREADS as a fallback in case NUMEXPR_NUM_THREADS is not
  set. Fixes #161. (PR #175, Stefan Erb).

* Added support for AppVeyor (PR #178 Andrea Bedini)

* Fix to allow numexpr to be imported after eventlet.monkey_patch(),
  as suggested in #118 (PR #180 Ben Moran).

* Fix harmless data race that triggers false positives in ThreadSanitizer.
  (PR #179, Clement Courbet).

* Fixed some string tests on Python 3 (PR #182, Antonio Valentino).


Changes from 2.4.2 to 2.4.3
===========================

* Comparisons with empty strings work correctly now.  Fixes #121 and
  PyTables #184.

Changes from 2.4.1 to 2.4.2
===========================

* Improved setup.py so that pip can query the name and version without
  actually doing the installation.  Thanks to Joris Borgdorff.

Changes from 2.4 to 2.4.1
=========================

* Added more configuration examples for compiling with MKL/VML
  support.  Thanks to Davide Del Vento.

* Symbol MKL_VML changed into MKL_DOMAIN_VML because the former is
  deprecated in newer MKL.  Thanks to Nick Papior Andersen.

* Better determination of methods in `cpuinfo` module.  Thanks to Marc
  Jofre.

* Improved NumPy version determination (handy for 1.10.0).  Thanks
  to Åsmund Hjulstad.

* Benchmarks run now with both Python 2 and Python 3.  Thanks to Zoran
  Plesivčak.

Changes from 2.3.1 to 2.4
=========================

* A new `contains()` function has been added for detecting substrings
  in strings.  Only plain strings (bytes) are supported for now.  See
  PR #135 and ticket #142.  Thanks to Marcin Krol.

* New version of setup.py that allows better management of NumPy
  dependency.  See PR #133.  Thanks to Aleks Bunin.

Changes from 2.3 to 2.3.1
=========================

* Added support for shift-left (<<) and shift-right (>>) binary operators.
  See PR #131. Thanks to fish2000!

* Removed the rpath flag for the GCC linker, because it is probably
  not necessary and it chokes to clang.

2.3.1

_This is a micro release and I have very little time on my hands right now sorry_

    Fix crash with no values when the print_values_position param is set (thanks @cristen)

2.3.0

    New call API: chart = Line(fill=True); chart.add('title', [1, 3, 12]); chart.render() can now be replaced with Line(fill=True)(1, 3, 12, title='title').render()
    Drop python 2.6 support

2.2.3

    Fix bar static value positioning (#315)

v0.8.1							2017/02/22

* This release fixes an issue with I18n.transliterate and Chinese
  characters. See #362 for more information.

v0.8.0							2017/01/31

Notable changes

* You can now set I18n.cache_key_digest to determine how cache keys are
  calculated. If you were seeing issues where the same value stored in a cache
  produced a different key, then this fix will interest you. For more
  information, see #285.

* You can now override translate_format in I18n::Backend classes to customize
  how localize will perform. See #347 (comment) for more details.

* You can now interpolate the value of a key inside another key. See #300 for
  more information.

* The exists? method was added to the fallback backend, to match other backend
  implementations - #326

* Added N_ to GetText::Helpers - #121

* Added a :default option for I18n.localize - #251

Bug fixes

* Reverted a commit which made it so that the great documentation for
  I18n.translate wasn't made visible through a yard documentation
  generation. - bc926eb

* I18n.MissingTranslation.new can now be called with two arguments. It will no
  longer raise a "TypeError: can't dup NilClass" exception - #295

* I18n's Hash#slice method no longer fails if the hash does not have the
  specified key - #289

* I18n::Backend::Metadata will now no longer attempt to set
  @translation_metadata on frozen objects - #305

* Added missing many rule to pl translation rules - #346

* Calling I18n.t(:foo, default: nil) Or I18n.t(:foo, default: false) will now
  return nil or false, rather than returning a missing translation exception -
  #144

* Setting I18n.load_path via I18n.load_path= will now reset the
  @@available_locales_set setting. - #348 & #173

* The subclasses of Hash when calling Hash#slice are maintained - #250

* Fixed I18n.interpolate behaviour when it was passed an
  ActiveSupport::SafeBuffer object - #216
