Ref [PyCQA/astroid#​1360](https://togithub.com/PyCQA/astroid/issues/1360) Closes [#​4826](https://togithub.com/PyCQA/pylint/issues/4826) - Output better error message if unsupported file formats are used with `pyreverse`. Closes [#​5950](https://togithub.com/PyCQA/pylint/issues/5950) - Fix pyreverse diagrams type hinting for classmethods and staticmethods. - Fix pyreverse diagrams type hinting for methods returning None. - Fix matching `--notes` options that end in a non-word character. Closes [#​5840](https://togithub.com/PyCQA/pylint/issues/5840) - Updated the position of messages for class and function defintions to no longer cover the complete definition. Only the `def` or `class` + the name of the class/function are covered. Closes [#​5466](https://togithub.com/PyCQA/pylint/issues/5466) - `using-f-string-in-unsupported-version` and `using-final-decorator-in-unsupported-version` msgids were renamed from `W1601` and `W1602` to `W2601` and `W2602`. Disabling using these msgids will break. This is done in order to restore consistency with the already existing msgids for `apply-builtin` and `basestring-builtin` from the now deleted python 3K+ checker. There is now a check that we're not using existing msgids or symbols from deleted checkers. Closes [#​5729](https://togithub.com/PyCQA/pylint/issues/5729) - The line numbering for messages related to function arguments is now more accurate. This can require some message disables to be relocated to updated positions. - Add `--recursive` option to allow recursive discovery of all modules and packages in subtree. Running pylint with `--recursive=y` option will check all discovered `.py` files and packages found inside subtree of directory provided as parameter to pylint. Closes [#​352](https://togithub.com/PyCQA/pylint/issues/352) - Add `modified-iterating-list`, `modified-iterating-dict` and `modified-iterating-set`, emitted when items are added to or removed from respectively a list, dictionary or set being iterated through. Closes [#​5348](https://togithub.com/PyCQA/pylint/issues/5348) - Fix false-negative for `assignment-from-none` checker using list.sort() method. closes [#​5722](https://togithub.com/PyCQA/pylint/issues/5722) - New extension `import-private-name`: indicate imports of external private packages and objects (prefixed with `_`). It can be loaded using `load-plugins=pylint.extensions.private_import`. Closes [#​5463](https://togithub.com/PyCQA/pylint/issues/5463) - Fixed crash from `arguments-differ` and `arguments-renamed` when methods were defined outside the top level of a class. Closes [#​5648](https://togithub.com/PyCQA/pylint/issues/5648) - Removed the deprecated `check_docs` extension. You can use the `docparams` checker to get the checks previously included in `check_docs`. Closes [#​5322](https://togithub.com/PyCQA/pylint/issues/5322) - Added a `testutil` extra require to the packaging, as `gitpython` should not be a dependency all the time but is still required to use the primer helper code in `pylint.testutil`. You can install it with `pip install pylint[testutil]`. Closes [#​5486](https://togithub.com/PyCQA/pylint/issues/5486) - Reinstated checks from the python3 checker that are still useful for python 3 (`eq-without-hash`). This is now in the `pylint.extensions.eq_without_hash` optional extension. Closes [#​5025](https://togithub.com/PyCQA/pylint/issues/5025) - Fixed an issue where `ungrouped-imports` could not be disabled without raising `useless-suppression`. Ref [#​2366](https://togithub.com/PyCQA/pylint/issues/2366) - Added several checkers to deal with unicode security issues (see `Trojan Sources `\_ and `PEP 672 `\_ for details) that also concern the readability of the code. In detail the following checks were added: - `bad-file-encoding` checks that the file is encoded in UTF-8 as suggested by `PEP8 `*. UTF-16 and UTF-32 are `not supported by Python `* at the moment. If this ever changes `invalid-unicode-codec` checks that they aren't used, to allow for backwards compatibility. - `bidirectional-unicode` checks for bidirectional unicode characters that could make code execution different than what the user expects. - `invalid-character-backspace`, `invalid-character-carriage-return`, `invalid-character-sub`, `invalid-character-esc`, `invalid-character-zero-width-space` and `invalid-character-nul` to check for possibly harmful unescaped characters. Closes [#​5281](https://togithub.com/PyCQA/pylint/issues/5281) - Use the `tomli` package instead of `toml` to parse `.toml` files. Closes [#​5885](https://togithub.com/PyCQA/pylint/issues/5885) - Fix false positive - Allow unpacking of `self` in a subclass of `typing.NamedTuple`. Closes [#​5312](https://togithub.com/PyCQA/pylint/issues/5312) - Fixed false negative `unpacking-non-sequence` when value is an empty list. Closes [#​5707](https://togithub.com/PyCQA/pylint/issues/5707) - Better warning messages for useless else or elif when a function returns early. Closes [#​5614](https://togithub.com/PyCQA/pylint/issues/5614) - Fixed false positive `consider-using-dict-comprehension` when creating a dict using a list of tuples where key AND value vary depending on the same condition. Closes [#​5588](https://togithub.com/PyCQA/pylint/issues/5588) - Fixed false positive for `global-variable-undefined` when `global` is used with a class name Closes [#​3088](https://togithub.com/PyCQA/pylint/issues/3088) - Fixed false positive for `unused-variable` when a `nonlocal` name is assigned as part of a multi-name assignment. Closes [#​3781](https://togithub.com/PyCQA/pylint/issues/3781) - Fixed a crash in `unspecified-encoding` checker when providing `None` to the `mode` argument of an `open()` call. Closes [#​5731](https://togithub.com/PyCQA/pylint/issues/5731) - Fixed a crash involving a `NewType` named with an f-string. Closes [#​5770](https://togithub.com/PyCQA/pylint/issues/5770) Ref [PyCQA/astroid#​1400](https://togithub.com/PyCQA/astroid/issues/1400) - Improved `bad-open-mode` message when providing `None` to the `mode` argument of an `open()` call. Closes [#​5733](https://togithub.com/PyCQA/pylint/issues/5733) - Added `lru-cache-decorating-method` checker with checks for the use of `functools.lru_cache` on class methods. This is unrecommended as it creates memory leaks by never letting the instance getting garbage collected. Closes [#​5670](https://togithub.com/PyCQA/pylint/issues/5670) - Fixed crash with recursion error for inference of class attributes that referenced the class itself. Closes [#​5408](https://togithub.com/PyCQA/pylint/issues/5408) Ref [PyCQA/astroid#​1392](https://togithub.com/PyCQA/astroid/issues/1392) - Fixed false positive for `unused-argument` when a method overridden in a subclass does nothing with the value of a keyword-only argument. Closes [#​5771](https://togithub.com/PyCQA/pylint/issues/5771) Ref [PyCQA/astroid#​1382](https://togithub.com/PyCQA/astroid/issues/1382) - The issue template for crashes is now created for crashes which were previously not covered by this mechanism. Closes [#​5668](https://togithub.com/PyCQA/pylint/issues/5668) - Rewrote checker for `non-ascii-name`. It now ensures **all** Python names are ASCII and also properly checks the names of imports (`non-ascii-module-import`) as well as file names (`non-ascii-file-name`) and emits their respective new warnings. Non ASCII characters could be homoglyphs (look alike characters) and hard to enter on a non specialized keyboard. See `Confusable Characters in PEP 672 `\_ - When run in parallel mode `pylint` now pickles the data passed to subprocesses with the `dill` package. The `dill` package has therefore been added as a dependency. - An astroid issue where symlinks were not being taken into account was fixed Closes [#​1470](https://togithub.com/PyCQA/pylint/issues/1470) Closes [#​3499](https://togithub.com/PyCQA/pylint/issues/3499) Closes [#​4302](https://togithub.com/PyCQA/pylint/issues/4302) Closes [#​4798](https://togithub.com/PyCQA/pylint/issues/4798) Closes [#​5081](https://togithub.com/PyCQA/pylint/issues/5081) - Fix a crash in `unused-private-member` checker when analyzing code using `type(self)` in bound methods.

Closes [#​5724](https://togithub.com/PyCQA/pylint/issues/5724) - Fix false positives for `used-before-assignment` from using named expressions in a ternary operator test and using that expression as a call argument. Closes [#​5177](https://togithub.com/PyCQA/pylint/issues/5177), [#​5212](https://togithub.com/PyCQA/pylint/issues/5212) - Fix false positive for `undefined-variable` when `namedtuple` class attributes are used as return annotations. Closes [#​5568](https://togithub.com/PyCQA/pylint/issues/5568) - Fix false negative for `undefined-variable` and related variable messages when the same undefined variable is used as a type annotation and is accessed multiple times, or is used as a default argument to a function. Closes [#​5399](https://togithub.com/PyCQA/pylint/issues/5399) - Pyreverse - add output in mermaidjs format - Emit `used-before-assignment` instead of `undefined-variable` when attempting to access unused type annotations. Closes [#​5713](https://togithub.com/PyCQA/pylint/issues/5713) - Added confidence level `CONTROL_FLOW` for warnings relying on assumptions about control flow. - `used-before-assignment` now considers that assignments in a try block may not have occurred when the except or finally blocks are executed. Closes [#​85](https://togithub.com/PyCQA/pylint/issues/85), [#​2615](https://togithub.com/PyCQA/pylint/issues/2615) - Fixed false negative for `used-before-assignment` when a conditional or context manager intervened before the try statement that suggested it might fail. Closes [#​4045](https://togithub.com/PyCQA/pylint/issues/4045) - Fixed false negative for `used-before-assignment` in finally blocks if an except handler did not define the assignment that might have failed in the try block. - Fixed extremely long processing of long lines with comma's. Closes [#​5483](https://togithub.com/PyCQA/pylint/issues/5483) - Fixed crash on properties and inherited class methods when comparing them for equality against an empty dict. Closes [#​5646](https://togithub.com/PyCQA/pylint/issues/5646) - Fixed a false positive for `assigning-non-slot` when the slotted class defined `__setattr__`. Closes [#​3793](https://togithub.com/PyCQA/pylint/issues/3793) - Fixed a false positive for `invalid-class-object` when the object being assigned to the `__class__` attribute is uninferable. - Fixed false positive for `used-before-assignment` with self-referential type annotation in conditional statements within class methods. Closes [#​5499](https://togithub.com/PyCQA/pylint/issues/5499) - Add checker `redefined-slots-in-subclass`: Emitted when a slot is redefined in a subclass. Closes [#​5617](https://togithub.com/PyCQA/pylint/issues/5617) - Fixed false positive for `global-variable-not-assigned` when the `del` statement is used Closes [#​5333](https://togithub.com/PyCQA/pylint/issues/5333) - By default, pylint does no longer take files starting with `.#` into account. Those are considered `Emacs file locks`. See https://www.gnu.org/software/emacs/manual/html_node/elisp/File-Locks.html. This behavior can be reverted by redefining the `ignore-patterns` option.

Closes [#​5500](https://togithub.com/PyCQA/pylint/issues/5500) - Fixed a false negative for `used-before-assignment` when some but not all except handlers defined a name relied upon after an except block when the corresponding try block contained a return statement. Closes [#​5524](https://togithub.com/PyCQA/pylint/issues/5524) - When evaluating statements in the `else` clause of a loop, `used-before-assignment` assumes that assignments in the except blocks took place if the except handlers constituted the only ways for the loop to finish without breaking early.

Closes [#​5654](https://togithub.com/PyCQA/pylint/issues/5654) - Some files in `pylint.testutils` were deprecated. In the future imports should be done from the `pylint.testutils.functional` namespace directly. - Fixed false positives for `no-value-for-parameter` with variadic positional arguments. Closes [#​5416](https://togithub.com/PyCQA/pylint/issues/5416) - `safe_infer` no longer makes an inference when given two function definitions with differing numbers of arguments.
