***************************
What's New in Pylint 2.12
***************************
:Release: 2.12
:Date: TBA
Summary -- Release highlights
=============================
New checkers
============
* Added ``missing-any-param-doc`` triggered when a function has neither parameter nor parameter type
documentation. Undocumented parameters are now being properly identified. A warning might start to
appear unexpectedly if ``missing-param-doc`` and ``missing-type-doc`` were disabled, as a new message
``missing-any-param-doc`` will be emitted instead.
Closes #3799
* Checkers for ``typing.final``
* Added ``overridden-final-method``: Emitted when a method which is annotated with ``typing.final`` is overridden
* Added ``subclassed-final-class``: Emitted when a class which is annotated with ``typing.final`` is subclassed
Closes #3197
* Created new ``UnsupportedVersionChecker`` checker class that includes checks for features
not supported by all versions indicated by a ``py-version``.
* Added ``using-f-string-in-unsupported-version`` checker. Issued when ``py-version``
is set to a version that does not support f-strings (< 3.6)
* Fix ``useless-super-delegation`` false positive when default keyword argument is a variable.
* Added new checker `use-implicit-booleanness``: Emitted when using collection
literals for boolean comparisons
* Added new checker ``use-implicit-booleaness-not-comparison``: Emitted when
collection literal comparison is being used to check for emptiness.
Closes #4774
* Added configuration option ``exclude-too-few-public-methods`` to allow excluding
classes from the ``min-public-methods`` checker.
Closes #3370
Removed checkers
================
Extensions
==========
* Added an optional extension ``consider-using-any-or-all``: Emitted when a ``for`` loop only
produces a boolean and could be replaced by ``any`` or ``all`` using a generator. Also suggests
a suitable any/all statement if it is concise.
Closes #5008
Other Changes
=============
* Fix ``install graphiz`` message which isn't needed for puml output format.
* Fix ``simplify-boolean-expression`` when condition can be inferred as False.
Closes #5200
* Fix exception when pyreverse parses ``property function`` of a class.
* Improve and flatten ``unused-wildcard-import`` message
Closes #3859
* In length checker, ``len-as-condition`` has been renamed as
``use-implicit-booleaness-not-len`` in order to be consistent with
``use-implicit-booleaness-not-comparison``.
* Fixed ``protected-access`` for accessing of attributes and methods of inner classes
Closes #3066
* Update ``literal-comparison``` checker to ignore tuple literals
Closes #3031
* ``undefined-variable`` now correctly flags variables which only receive a type annotations
and never get assigned a value
Closes #5140
* ``undefined-variable`` now correctly considers the line numbering and order of classes
used in metaclass declarations
Closes #4031
* ``used-before-assignment`` now correctly considers references to classes as type annotation
or default values in first-level methods
Closes #3771
* ``undefined-variable`` and ``unused-variable`` now correctly trigger for assignment expressions
in functions defaults
Fixes part of #3688
* ``undefined-variable`` now correctly triggers for assignment expressions in if ... else statements
This includes a basic form of control flow inference for if ... else statements using
constant boolean values
Closes #3688
* Fix double emitting of ``not-callable`` on inferrable ``properties``
Closes #4426
* Support configuring mixin class pattern via ``mixin-class-rgx``
* Normalize the input to the ``ignore-paths`` option to allow both Posix and
Windows paths
Closes #5194
* ``mising-param-doc`` now correctly parses asterisks for variable length and
keyword parameters
Closes #3733
* ``mising-param-doc`` now correctly handles Numpy parameter documentation without
explicit typing
Closes #5222
* The ``--jobs`` parameter now falls back to 1 if the host operating system does not
have functioning shared semaphore implementation.
Closes #5216
