Closes #4498
* ``consider-using-with`` is no longer triggered if a context manager is returned from a function.

* 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.

Closes #4744
* Fixed a crash when importing beyond the top level package during ``import-error``
message creation

Closes #3826
* Improved the Similarity checker performance. Fix issue with ``--min-similarity-lines`` used with ``--jobs``.

* 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 #4673
* Fix crash for ``unused-private-member`` that occurred with nested attributes.
Closes #4755

* 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
* Fixed bug with ``cell-var-from-loop`` checker: it no longer has false negatives when
both ``unused-variable`` and ``used-before-assignment`` are disabled.
* Fix false postive for ``invalid-all-format`` if the list or tuple builtin functions are used
Closes #4711
* Config files can now contain environment variables
Closes #3839

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

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 #1159
* Fix issue with PEP 585 syntax and the use of ``collections.abc.Set``
