Pylint's ChangeLog
------------------
What's New in Pylint 2.12.0?
============================
Release date: TBA
..
Put new features here and also in 'doc/whatsnew/2.12.rst'
What's New in Pylint 2.11.1?
============================
Release date: TBA
..
Put bug fixes that should not wait for a new minor version here
* ``unspecified-encoding`` now checks the encoding of ``pathlib.Path()`` correctly
Closes #5017
What's New in Pylint 2.11.0?
============================
Release date: 2021-09-16
* The python3 porting mode checker and it's ``py3k`` option were removed. You can still find it in older pylint
versions.
* ``raising-bad-type`` is now properly emitted when raising a string
* Added new extension ``SetMembershipChecker`` with ``use-set-for-membership`` check:
Emitted when using an in-place defined ``list`` or ``tuple`` to do a membership test. ``sets`` are better optimized for that.
Closes #4776
* Added ``py-version`` config key (if ``[MASTER]`` section). Used for version dependant checks.
Will default to whatever Python version pylint is executed with.
* ``CodeStyleChecker``
* Added ``consider-using-assignment-expr``: Emitted when an assignment is directly followed by an if statement
and both can be combined by using an assignment expression ``:=``. Requires Python 3.8
Closes #4862
* Added ``consider-using-f-string``: Emitted when .format() or '%' is being used to format a string.
Closes #3592
* Fix false positive for ``consider-using-with`` if a context manager is assigned to a
variable in different paths of control flow (e. g. if-else clause).
Closes #4751
* https is now prefered in the documentation and http://pylint.pycqa.org correctly redirect to https://pylint.pycqa.org
Closes #3802
* Fix false positive for ``function-redefined`` for simple type annotations
Closes #4936
* Fix false positive for ``protected-access`` if a protected member is used in type hints of function definitions
* Fix false positive ``dict-iter-missing-items`` for dictionaries only using tuples as keys
Closes #3282
* The ``unspecified-encoding`` checker now also checks calls to ``pathlib.Path().read_text()``
and ``pathlib.Path().write_text()``
Closes #4945
* Fix false positive ``superfluous-parens`` for tuples created with inner tuples
Closes #4907
* Fix false positive ``unused-private-member`` for accessing attributes in a class using ``cls``
Closes #4849
* Fix false positive ``unused-private-member`` for private staticmethods accessed in classmethods.
Closes #4849
* Extended ``consider-using-in`` check to work for attribute access.
* Setting ``min-similarity-lines`` to 0 now makes the similarty checker stop checking for duplicate code
Closes #4901
* Fix a bug where pylint complained if the cache's parent directory does not exist
Closes #4900
* The ``global-variable-not-assigned`` checker now catches global variables that are never reassigned in a
local scope and catches (reassigned) functions
Closes #1375
Closes #330
* Fix false positives for invalid-all-format that are lists or tuples at runtime
Closes #4711
* Fix ``no-self-use`` and ``docparams extension`` for async functions and methods.
* Add documentation for ``pyreverse`` and ``symilar``
Closes #4616
* Non symbolic messages with the wrong capitalisation now correctly trigger ``use-symbolic-message-instead``
Closes #5000
* The ``consider-iterating-dictionary`` checker now also considers membership checks
Closes #4069
* The ``invalid-name`` message is now more detailed when using multiple naming style regexes.
What's New in Pylint 2.10.2?
============================
Release date: 2021-08-21
* We now use platformdirs instead of appdirs since the latter is not maintained.
Closes #4886
* Fix a crash in the checker raising ``shallow-copy-environ`` when failing to infer
on ``copy.copy``
Closes #4891
What's New in Pylint 2.10.1?
============================
Release date: 2021-08-20
* pylint does not crash when PYLINT_HOME does not exist.
Closes #4883
What's New in Pylint 2.10.0?
============================
Release date: 2021-08-20
* pyreverse: add option to produce colored output.
Closes #4488
* pyreverse: add output in PlantUML format.
Closes #4498
* ``consider-using-with`` is no longer triggered if a context manager is returned from a function.
Closes #4748
* pylint does not crash with a traceback anymore when a file is problematic. It
creates a template text file for opening an issue on the bug tracker instead.
The linting can go on for other non problematic files instead of being impossible.
* pyreverse: Show class has-a relationships inferred from the type-hint
Closes #4744
* Fixed a crash when importing beyond the top level package during ``import-error``
message creation
Closes #4775
* Added ``ignored-parents`` option to the design checker to ignore specific
classes from the ``too-many-ancestors`` check (R0901).
Partially closes #3057
* Added ``unspecified-encoding``: Emitted when open() is called without specifying an encoding
Closes #3826
* Improved the Similarity checker performance. Fix issue with ``--min-similarity-lines`` used with ``--jobs``.
Close #4120
Close #4118
* Don't emit ``no-member`` error if guarded behind if statement.
Ref #1162
Closes #1990
Closes #4168
* The default for ``PYLINTHOME`` is now the standard ``XDG_CACHE_HOME``, and pylint now uses ``appdirs``.
Closes #3878
* Added ``use-list-literal``: Emitted when ``list()`` is called with no arguments instead of using ``[]``
Closes #4365
* Added ``use-dict-literal``: Emitted when ``dict()`` is called with no arguments instead of using ``{}``
Closes #4365
* Added optional extension ``consider-ternary-expression``: Emitted whenever a variable is assigned in both branches of an if/else block.
Closes # 4366
* Added optional extension ``while-used``: Emitted whenever a ``while`` loop is used.
Closes # 4367
* Added ``forgotten-debug-statement``: Emitted when ``breakpoint``, ``pdb.set_trace`` or ``sys.breakpointhook`` calls are found
Closes #3692
* Fix false-positive of ``unused-private-member`` when using nested functions in a class
Closes #4673
* Fix crash for ``unused-private-member`` that occurred with nested attributes.
Closes #4755
* Fix a false positive for ``unused-private-member`` with class names
Closes #4681
* Fix false positives for ``superfluous-parens`` with walrus operator, ternary operator and inside list comprehension.
Closes #2818
Closes #3249
Closes #3608
Closes #4346
* Added ``format-string-without-interpolation`` checker: Emitted when formatting is applied to a string without any variables to be replaced
Closes #4042
* Refactor of ``--list-msgs`` & ``--list-msgs-enabled``: both options now show whether messages are emittable with the current interpreter.
Closes #4778
* Fix false negative for ``used-before-assignment`` when the variable is assigned
in an exception handler, but used outside of the handler.
Closes #626
* Added ``disable-next`` option: allows using `# pylint: disable-next=msgid` to disable a message for the following line
Closes #1682
* Added ``redundant-u-string-prefix`` checker: Emitted when the u prefix is added to a string
Closes #4102
* Fixed ``cell-var-from-loop`` checker: handle cell variables in comprehensions within functions,
and function default argument expressions. Also handle basic variable shadowing.
Closes #2846
Closes #3107
