What's New in Pylint 2.8.3?

Release date: 2021-05-31

  • Astroid has been pinned to 2.5.6 for the 2.8 branch.

    Refs #4527

What's New in Pylint 2.8.2?

Release date: 2021-04-26

  • Keep __pkginfo__.numversion a tuple to avoid breaking pylint-django.

    Closes #4405

  • scm_setuptools has been added to the packaging.

  • Pylint's tags are now the standard form vX.Y.Z and not pylint-X.Y.Z anymore.

  • New warning message deprecated-class. This message is emitted if import or call deprecated class of the standard library (like collections.Iterable that will be removed in Python 3.10).

    Closes #4388

What's New in Pylint 2.8.1?

Release date: 2021-04-25

  • Add numversion back (temporarily) in __pkginfo__ because it broke Pylama and revert the unnecessary pylint.version breaking change.

    Closes #4399

What's New in Pylint 2.8.0?

Release date: 2021-04-24

  • New refactoring message consider-using-with. This message is emitted if resource-allocating functions or methods of the standard library (like open() or threading.Lock.acquire()) that can be used as a context manager are called without a with block.

    Closes #3413

  • Resolve false positives on unused variables in decorator functions

    Closes #4252

  • Add new extension ConfusingConsecutiveElifChecker. This optional checker emits a refactoring message (R5601 confusing-consecutive-elif) if if/elif statements with different indentation levels follow directly one after the other.

  • New option --output=<file> to output result to a file rather than printing to stdout.

    Closes #1070

  • Use a prescriptive message for unidiomatic-typecheck

    Closes #3891

  • Apply const-naming-style to module constants annotated with typing.Final

  • The packaging is now done via setuptools exclusively. doc, tests, man, elisp and Changelog are not packaged anymore - reducing the size of the package by 75%.

  • Debian packaging is now (officially) done in https://salsa.debian.org/python-team/packages/pylint.

  • The 'doc' extra-require has been removed.

  • __pkginfo__ now only contain __version__ (also accessible with pylint.__version__), other meta-information are still accessible with from importlib import metadata;metadata.metadata('pylint').

  • COPYING has been renamed to LICENSE for standardization.

  • Fix false-positive used-before-assignment in function returns.

    Closes #4301

  • Updated astroid to 2.5.3

    Closes #2822, #4206, #4284

  • Add consider-using-min-max-builtin check for if statement which could be replaced by Python builtin min or max

    Closes #3406

  • Don't auto-enable postponed evaluation of type annotations with Python 3.10

  • Update astroid to 2.5.4

  • Add new extension TypingChecker. This optional checker can detect the use of deprecated typing aliases and can suggest the use of the alternative union syntax where possible. (For example, 'typing.Dict' can be replaced by 'dict', and 'typing.Unions' by '|', etc.) Make sure to check the config options if you plan on using it!

  • Reactivates old counts in report mode.

    Closes #3819

  • During detection of inconsistent-return-statements consider that assert False is a return node.

    Closes #4019

  • Run will not fail if score exactly equals config.fail_under.

  • Functions that never returns may declare NoReturn as type hints, so that inconsistent-return-statements is not emitted.

    Closes #4122, #4188

  • Improved protected access checks to allow access inside class methods

    Closes #1159

  • Fix issue with PEP 585 syntax and the use of collections.abc.Set

  • Fix issue that caused class variables annotated with typing.ClassVar to be identified as class constants. Now, class variables annotated with typing.Final are identified as such.

    Closes #4277

  • Continuous integration with read the doc has been added.

    Closes #3850

  • Don't show DuplicateBasesError for attribute access

  • Fix crash when checking setup.cfg for pylint config when there are non-ascii characters in there

    Closes #4328

  • Allow code flanked in backticks to be skipped by spellchecker

    Closes #4319

  • Allow Python tool directives (for black, flake8, zimports, isort, mypy, bandit, pycharm) at beginning of comments to be skipped by spellchecker

    Closes #4320

  • Fix issue that caused Emacs pylint to fail when used with tramp

  • Improve check for invalid PEP 585 syntax inside functions if postponed evaluation of type annotations is enabled

  • Improve check for invalid PEP 585 syntax as default function arguments
