3.1.0

You can view the 3.1.0 milestone_ on GitLab for more details.

Add --bug-report flag to make issue reporters' lives easier.

Collect configuration files from the current directory when using our Git
hook. (See also GitLab210, GitLab218, GitLab223_)

Avoid unhandled exceptions when dealing with SyntaxErrors. (See also
GitLab214, GitLab238)

Exit early if the value for --diff is empty. (See also GitLab226_)

Handle empty --stdin-display-name values. (See also GitLab235_)

Properly report the column number of Syntax Errors. We were assuming that
all reports of column numbers were 0-indexed, however, SyntaxErrors report
the column number as 1-indexed. This caused us to report a column number
that was 1 past the actual position. Further, when combined with
SyntaxErrors that occur at a newline, this caused the position to be
visually off by two. (See also GitLab237_)

Fix the behaviour of --enable-extensions. Previously, items specified
here were still ignored due to the fact that the off-by-default extension
codes were being left in the ignore list. (See also GitLab239_)

Fix problems around --select and --ignore behaviour that prevented
codes that were neither explicitly selected nor explicitly ignored from
being reported. (See also GitLab242_)

Truly be quiet when the user specifies -q one or more times. Previously,
we were showing the if the user specified -q and --show-source. We
have fixed this bug. (See also GitLab245_)

Add new File Processor attribute, previous_unindented_logical_line to
accommodate pycodestyle 2.1.0. (See also GitLab246_)

When something goes wrong, exit non-zero. (See also GitLab248,
GitLab209)

Add --tee as an option to allow use of --output-file and printing to
standard out.

Allow the git plugin to actually be lazy when collecting files.

Allow for pycodestyle 2.1 series and pyflakes 1.3 series.

3.0.3

Disable --jobs for any version of Python on Windows.
(See also this Python bug report_)

Raise exception when entry_point in plugin not callable.
This raises an informative error when a plugin fails to load because its
entry_point is not callable, which can happen with a plugin which is buggy or
not updated for the current version of flake8. This is nicer than raising a
PicklingError about failing to pickle a module (See also GitLab164_)

Fix noqa comments followed by a : and explanation broken by
3.0.0 (See also GitLab178_)

Always open our output file in append mode so we do not overwrite log
messages. (See also GitLab193_)

When normalizing path values read from configuration, keep in context the
directory where the configuration was found so that relative paths work.
(See also GitLab194_)

Fix issue where users were unable to ignore plugin errors that were on
by default. (See also GitLab195_)

Fix our legacy API StyleGuide's init_report method to actually override
the previous formatter. (See also GitLab200_)

at 0 instead of 1.

Fix regression in handling of errors like E402 that rely on a combination of
attributes. (See also GitLab186_)

3.0.0

Rewrite our documentation from scratch! (http://flake8.pycqa.org)

Drop explicit support for Pythons 2.6, 3.2, and 3.3.

Remove dependence on pep8/pycodestyle for file processing, plugin
dispatching, and more. We now control all of this while keeping backwards
compatibility.

--select and --ignore can now both be specified and try to find the
most specific rule from each. For example, if you do --select E --ignore E123 then we will report everything that starts with E except for
E123. Previously, you would have had to do --ignore E123,F,W which
will also still work, but the former should be far more intuitive.

Add support for in-line noqa comments to specify only the error
codes to be ignored, e.g., noqa: E123,W503

Add entry-point for formatters as well as a base class that new formatters
can inherit from. See the documentation for more details.

Add detailed verbose output using the standard library logging module.

Enhance our usage of optparse for plugin developers by adding new parameters
to the add_option that plugins use to register new options.

Update --install-hook to require the name of version control system hook
you wish to install a Flake8.

Stop checking sub-directories more than once via the setuptools command

When passing a file on standard-in, allow the caller to specify
--stdin-display-name so the output is properly formatted

The Git hook now uses sys.executable to format the shebang line.
This allows Flake8 to install a hook script from a virtualenv that points to
that virtualenv's Flake8 as opposed to a global one (without the virtualenv
being sourced).

Print results in a deterministic and consistent ordering when used with
multiprocessing

When using --count, the output is no longer written to stderr.

AST plugins can either be functions or classes and all plugins can now
register options so long as there are callable attributes named as we
expect.

Stop forcibly re-adding .tox, .eggs, and *.eggs to
--exclude. Flake8 2.x started always appending those three patterns
to any exclude list (including the default and any user supplied list).
Flake8 3 has stopped adding these in, so you may see errors when upgrading
due to these patterns no longer being forcibly excluded by default if you
have your own exclude patterns specified.

To fix this, add the appropriate patterns to your exclude patterns list.

 This item was added in November of 2016, as a result of a bug
 report.

=========================

Release date: 2017-12-15

Respect disable=... in config file when running with --py3k.

New warning shallow-copy-environ added

 Shallow copy of os.environ doesn&#39;t work as people may expect. os.environ
 is not a dict object but rather a proxy object, so any changes made
 on copy may have unexpected effects on os.environ

 Instead of copy.copy(os.environ) method os.environ.copy() should be
 used.

 See https://bugs.python.org/issue15373 for details.

 Close 1301

Do not display no-absolute-import warning multiple times per file.

trailing-comma-tuple refactor check now extends to assignment with
more than one element (such as lists)

 Close 1713

Fixing u'' string in superfluous-parens message

 Close 1420

abstract-class-instantiated is now emitted for all inference paths.

  Close 1673

Add set of predefined naming style to ease configuration of checking
naming conventions.

 Closes 1013

Added a new check, keyword-arg-before-vararg

 This is emitted for function definitions
 in which keyword arguments are placed before variable
 positional arguments (*args).

 This may lead to args list getting modified if keyword argument&#39;s value
 is not provided in the function call assuming it will take default value
 provided in the definition.

The invalid-name check contains the name of the template that caused the failure

 Close 1176

Using the -j flag won't start more child linters than needed.

 Contributed by Roman Ivanov in 1614

Fix a false positive with bad-python3-import on relative imports

 Close 1608

Added a new Python 3 check, non-ascii-bytes-literals

 Close 1545

Added a couple of new Python 3 checks for accessing dict methods in non-iterable context

Protocol checks (not-a-mapping, not-an-iterable and co.) aren't emitted on classes with dynamic getattr

Added a new warning, 'bad-thread-instantiation'

 This message is emitted when the threading.Thread class does not
 receive the target argument, but receives just one argument, which
 is by default the group parameter.

Added parameter for limiting number of suggestions in spellchecking checkers

Fix a corner-case in consider-using-ternary checker.

 When object ``A`` used in  ``X and A or B`` was falsy in boolean context,
 Pylint incorrectly emitted non-equivalent ternary-based suggestion.

Don't emit by default no-member if we have opaque inference objects in the inference results

 This is controlled through the new flag ignore-on-opaque-inference, which is by
 default True. The inference can return  multiple potential results while
 evaluating a Python object, but some branches might not be evaluated, which
 results in partial inference. In that case, it might be useful to still emit
 no-member and other checks for the rest of the inferred objects.

Added new message assign-to-new-keyword to warn about assigning to names which
will become a keyword in future Python releases.

 Close 1351

'trailing-comma-tuple' check was added

 This message is emitted when pylint finds an one-element tuple,
 created by a stray comma. This can suggest a potential problem in the

 creation of a tuple, rather than relying on the comma itself.

Don't emit not-callable for instances with unknown bases.

ignored-argument-names is now used for ignoring arguments for unused-variable check.

 This option was used for ignoring arguments when computing the correct number of arguments
 a function should have, but for handling the arguments with regard
 to unused-variable check, dummy-variables-rgx was used instead. Now, ignored-argument-names
 is used for its original purpose and also for ignoring the matched arguments for
 the unused-variable check. This offers a better control of what should be ignored
 and how.
 Also, the same option was moved from the design checker to the variables checker,
 which means that the option now appears under the ``[VARIABLES]`` section inside
 the configuration file.
 Close 862.

Fix a false positive for keyword variadics with regard to keyword only arguments.

Add the ability to ignore files based on regex matching, with the new --ignore-patterns

 This addresses issue 156 by allowing for multiple ignore patterns

Do not emit import-error or no-name-in-module for fallback import blocks by default.

 Until now, we warned with these errors when a fallback import block (a TryExcept block
 that contained imports for Python 2 and 3) was found, but this gets cumbersome when
 trying to write compatible code. As such, we don&#39;t check these blocks by default,
 but the analysis can be enforced by using the new ``--analyse-fallback-block`` flag.

Use an OrderedDict for storing the configuration elements

 This fixes an issue related to impredictible order of the disable / enable
 elements from a config file. In certain cases, the disable was coming before
 the enable which resulted in classes of errors to be enabled, even though the intention
 was to disable them. The best example for this was in the context of running multiple
 processes, each one of it having different enables / disables that affected the output.

Handle the import fallback idiom with regard to wrong-import-order.

 Closes issue 750.

Decouple the displaying of reports from the displaying of messages

 Some reporters are aggregating the messages instead of displaying
 them when they are available. The actual displaying was conflatted
 in the generate_reports. Unfortunately this behaviour was flaky
 and in the case of the JSON reporter, the messages weren&#39;t shown
 at all if a file had syntax errors or if it was missing.
 In order to fix this, the aggregated messages can now be
 displayed with Reporter.display_message, while the reports are
 displayed with display_reports.

 Closes issues 766 and 765.

Ignore function calls with variadic arguments without a context.

 Inferring variadic positional arguments and keyword arguments
 will result into empty Tuples and Dicts, which can lead in
 some cases to false positives with regard to no-value-for-parameter.
 In order to avoid this, until we&#39;ll have support for call context
 propagation, we&#39;re ignoring such cases if detected.
 Closes issue 722.

Add wrong-import-position to check_messages's decorator arguments
for ImportChecker.leave_module
This fixes an esoteric bug which occurs when ungrouped-imports and
wrong-import-order are disabled and pylint is executed on multiple files.
What happens is that without wrong-import-position in check_messages,
leave_module will never be called, which means that the first non-import node
from other files might leak into the current file,
leading to wrong-import-position being emitted by pylint.

Fix a crash which occurred when old visit methods are encountered
in plugin modules. Closes issue 711.

Don't emit import-self and cyclic-import for relative imports
of modules with the same name as the package itself.
Closes issues 708 and 706.

1.5.0

===========================

Release date: 2015-11-29

Added multiple warnings related to imports. 'wrong-import-order'
is emitted when PEP 8 recommendations regarding imports are not
respected (that is, standard imports should be followed by third-party
imports and then by local imports). 'ungrouped-imports' is emitted
when imports from the same package or module are not placed
together, but scattered around in the code. 'wrong-import-position'
is emitted when code is mixed with imports, being recommended for the
latter to be at the top of the file, in order to figure out easier by
a human reader what dependencies a module has.
Closes issue 692.

Added a new refactoring warning, 'unneeded-not', emitted
when an expression with the not operator could be simplified.
Closes issue 670.

Added a new refactoring warning, 'simplifiable-if-statement',
used when an if statement could be reduced to a boolean evaluation
of its test. Closes issue 698.

Added a new refactoring warning, 'too-many-boolean-expressions',
used when an if statement contains too many boolean expressions,
which makes the code less maintainable and harder to understand.
Closes issue 677.

Property methods are shown as attributes instead of functions in
pyreverse class diagrams. Closes Issue 284

Add a new refactoring error, 'too-many-nested-blocks', which is emitted
when a function or a method has too many nested blocks, which makes the
code less readable and harder to understand. Closes issue 668.

Add a new error, 'unsubscriptable-object', that is emitted when
value used in subscription expression doesn't support subscription
(i.e. doesn't define getitem method).

Don't warn about abstract classes instantiated in their own
body. Closes issue 627.

Obsolete options are not present by default in the generated
configuration file. Closes issue 632.

non-iterator-returned can detect classes with iterator-metaclasses.
Closes issue 679.

Add a new error, 'unsupported-membership-test', emitted when value
to the right of the 'in' operator doesn't support membership test
protocol (i.e. doesn't define contains/iter/getitem)

Add new errors, 'not-an-iterable', emitted when non-iterable value
is used in an iterating context (starargs, for-statement,
comprehensions, etc), and 'not-a-mapping', emitted when non-mapping
value is used in a mapping context. Closes issue 563.

Make 'no-self-use' checker not emit a warning if there is a 'super()'
call inside the method.
Closes issue 667.

Add checker to identify multiple imports on one line.
Closes issue 598.

Fix unused-argument false positive when the "+=" operator is used.
Closes issue 518.

Don't emit import-error for ignored modules. PyLint will not emit import
errors for any import which is, or is a subpackage of, a module in
the ignored-modules list. Closes issue 223.

Fix unused-import false positive when the import is used in a
class assignment. Closes issue 475

Add a new error, 'not-context-manager', emitted when something
that doesn't implement enter and exit is used in a with
statement.

Add a new warning, 'confusing-with-statement', emitted by the
base checker, when an ambiguous looking with statement is used.
For example with open() as first, second which looks like a
tuple assignment but is actually 2 context managers.

Add a new warning, 'duplicate-except', emitted when there is an
exception handler which handles an exception type that was handled
before. Closes issue 485.

A couple of warnings got promoted to errors, since they could uncover
potential bugs in the code. These warnings are: assignment-from-none,
unbalanced-tuple-unpacking, unpacking-non-sequence, non-iterator-returned.
Closes issue 388.

Allow ending a pragma control with a semicolon. In this way, users
can continue a pragma control with a reason for why it is used,
as in pylint: disable=old-style-class;reason=....
Closes issue 449.

--jobs can be used with --load-plugins now. Closes issue 456.

Improve the performance of --jobs when dealing only with a package
name. Closes issue 479.

Don't emit an unused-wildcard-import when the imported name comes

The colorized reporter now works on Windows. Closes issue 96.

Remove pointless-except warning. It was previously disabled by
default and it wasn't very useful. Closes issue 506.

Fix a crash on Python 3 related to the string checker, which
crashed when it encountered a bytes string with a .format
method called.

Don't warn about no-self-use for builtin properties.

Fix a false positive for bad-reversed-sequence, when a subclass
of a dict provides a reversed method.

Change the default no-docstring-rgx so missing-docstring isn't
emitted for private functions.

Don't emit redefined-outer-name for future directives.
Closes issue 520.

Provide some hints for the bad-builtin message. Closes issue 522.

When checking for invalid arguments to a callable, in typecheck.py,
look up for the init in case the found new comes from builtins.

 Since the __new__ comes from builtins, it will not have attached any
 information regarding what parameters it expects, so the check
 will be useless. Retrieving __init__ in that case will at least
 detect a couple of false negatives. Closes issue 429.

Don't emit no-member for classes with unknown bases.

 Since we don&#39;t know what those bases might add, we simply ignore
 the error in this case.

Lookup in the implicit metaclass when checking for no-member,
if the class in question has an implicit metaclass, which is
True for new style classes. Closes issue 438.

Add two new warnings, duplicate-bases and inconsistent-mro.

 duplicate-bases is emitted when a class has the same bases
 listed more than once in its bases definition, while inconsistent-mro
 is emitted when no sane mro hierarchy can be determined. Closes issue 526.

Remove interface-not-implemented warning. Closes issue 532.

Remove the rest of interface checks: interface-is-not-class,
missing-interface-method, unresolved-interface. The reason is that
its better to start recommending ABCs instead of the old Zope era
of interfaces. One side effect of this change is that ignore-iface-methods
becomes a noop, it's deprecated and it will be removed at some time.

Emit a proper deprecation warning for reporters.BaseReporter.add_message.

 The alternative way is to use handle_message. add_message will be removed in
 Pylint 1.6.

Added new module 'extensions' for optional checkers with the test
directory 'test/extensions' and documentation file 'doc/extensions.rst'.

Added new checker 'extensions.check_docs' that verifies parameter
documention in Sphinx, Google, and Numpy style.

Detect undefined variable cases, where the "definition" of an undefined
variable was in del statement. Instead of emitting used-before-assignment,
which is totally misleading, it now emits undefined-variable.
Closes issue 528.

Don't emit attribute-defined-outside-init and access-member-before-definition
for mixin classes. Actual errors can occur in mixin classes, but this is
controlled by the ignore-mixin-members option. Closes issue 412.

Improve the detection of undefined variables and variables used before
assignment for variables used as default arguments to function,
where the variable was first defined in the class scope.
Closes issue 342 and issue 404.

Add a new warning, 'unexpected-special-method-signature', which is emitted
when a special method (dunder method) doesn't have the expected signature,
which can lead to actual errors in the application code.
Closes issue 253.

Remove 'bad-context-manager' due to the inclusion of 'unexpected-special-method-signature'.

Don't emit no-name-in-module if the import is guarded by an ImportError, Exception or
a bare except clause.

Don't emit no-member if the attribute access node is protected by an
except handler, which handles AttributeError, Exception or it is a
bare except.

Don't emit import-error if the import is guarded by an ImportError, Exception or a
bare except clause.

Don't emit undefined-variable if the node is guarded by a NameError, Exception
or bare except clause.

Add a new warning, 'using-constant-test', which is emitted when a conditional
statement (If, IfExp) uses a test which is always constant, such as numbers,
classes, functions etc. This is most likely an error from the user's part.
Closes issue 524.

Don't emit 'raising-non-exception' when the exception has unknown
bases. We don't know what those bases actually are and it's better
to assume that the user knows what he is doing rather than emitting
a message which can be considered a false positive.

Look for a .pylintrc configuration file in the current folder,
if pylintrc is not found. Dotted pylintrc files will not be searched
in the parents of the current folder, as it is done for pylintrc.

Add a new error, 'invalid-unary-type-operand', emitted when
an unary operand is used on something which doesn't support that
operation (for instance, using the unary bitwise inversion operator
