'bad-plugin-value' instead

Closes 4518

* ``invalid-length-returned``, now also works when nothing at all is returned
following an upgrade in astroid.

consistency. As such they don't necessarily provide a performance benefit
and are often times opinionated.

* New checker ``consider-using-tuple``. Emitted when an in-place defined
list or set can be replaced by a tuple.

* New checker ``consider-using-namedtuple-or-dataclass``. Emitted when dictionary values
can be replaced by namedtuples or dataclass instances.

Closes 4603

2.8.3

===========================
Release date: 2021-05-31

* Astroid has been pinned to 2.5.6 for the 2.8 branch see 4527.

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

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

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

2.7.4

===========================
Release date: 2021-03-30


* Fix a problem with disabled msgid not being ignored

Closes 4265
