### [`v2.15.2`](https://togithub.com/PyCQA/pylint/releases/tag/v2.15.2)
[Compare Source](https://togithub.com/PyCQA/pylint/compare/v2.15.0...v2.15.2)
- Fixed a case where custom plugins specified by command line could silently fail.
Specifically, if a plugin relies on the `init-hook` option changing `sys.path` before
it can be imported, this will now emit a `bad-plugin-value` message. Before this
change, it would silently fail to register the plugin for use, but would load
any configuration, which could have unintended effects.
Fixes part of [#7264](https://togithub.com/PyCQA/pylint/issues/7264).
- Fix `used-before-assignment` for functions/classes defined in type checking guard.
Closes [#7368](https://togithub.com/PyCQA/pylint/issues/7368)

as "documentation" for the `missing-param-doc` message.
Refs [#7398](https://togithub.com/PyCQA/pylint/issues/7398)
- Fix false positive for `unused-variable` and `unused-import` when a name is only used in a string literal type annotation.

- Fix false positive for `too-many-function-args` when a function call is assigned to a class attribute inside the class where the function is defined.
Closes [#6592](https://togithub.com/PyCQA/pylint/issues/6592)
- Fix `used-before-assignment` for functions/classes defined in type checking guard.

Closes [#4354](https://togithub.com/PyCQA/pylint/issues/4354)
- `missing-return-doc`, `missing-raises-doc` and `missing-yields-doc` now respect
the `no-docstring-rgx` option.
Closes [#4743](https://togithub.com/PyCQA/pylint/issues/4743)
- Don't crash on `OSError` in config file discovery.
Closes [#7169](https://togithub.com/PyCQA/pylint/issues/7169)
- `disable-next` is now correctly scoped to only the succeeding line.
Closes [#7401](https://togithub.com/PyCQA/pylint/issues/7401)
- Update `modified_iterating` checker to fix a crash with `for` loops on empty list.
Closes [#7380](https://togithub.com/PyCQA/pylint/issues/7380)
### [`v2.15.0`](https://togithub.com/PyCQA/pylint/releases/tag/v2.15.0)
[Compare Source](https://togithub.com/PyCQA/pylint/compare/v2.14.5...v2.15.0)
In pylint 2.15.0, we added a new check `missing-timeout` to warn of default timeout values that could cause a program to be hanging indefinitely.
We improved `pylint`'s handling of namespace packages. More packages should be linted without resorting to using the `--recursive=y` option.
We still welcome any community effort to help review, integrate, and add good/bad examples to the doc for [https://github.com/PyCQA/pylint/issues/5953](https://togithub.com/PyCQA/pylint/issues/5953). This should be doable without any `pylint` or `astroid` knowledge, so this is the perfect entrypoint if you want to contribute to `pylint` or open source without any experience with our code!
Internally, we changed the way we generate the release notes, thanks to DudeNr33. There will be no more conflict resolution to do in the changelog, and every contributor rejoice.
Marc Byrne became a maintainer, welcome to the team !

See https://peps.python.org/pep-0586/#literals-enums-and-forward-references for details. Refs [#3299](https://togithub.com/PyCQA/pylint/issues/3299) ## Other Changes - Add method name to the error messages of `no-method-argument` and `no-self-argument`. Closes [#7507](https://togithub.com/PyCQA/pylint/issues/7507) ### [`v2.15.3`](https://togithub.com/PyCQA/pylint/releases/tag/v2.15.3) [Compare Source](https://togithub.com/PyCQA/pylint/compare/v2.15.2...v2.15.3) - Fixed a crash in the `unhashable-member` checker when using a `lambda` as a dict key. Closes [#7453](https://togithub.com/PyCQA/pylint/issues/7453) - Fix a crash in the `modified-iterating-dict` checker involving instance attributes.

Closes [#7471](https://togithub.com/PyCQA/pylint/issues/7471) ### [`v2.15.2`](https://togithub.com/PyCQA/pylint/releases/tag/v2.15.2) [Compare Source](https://togithub.com/PyCQA/pylint/compare/v2.15.0...v2.15.2) - Fixed a case where custom plugins specified by command line could silently fail. Specifically, if a plugin relies on the `init-hook` option changing `sys.path` before it can be imported, this will now emit a `bad-plugin-value` message. Before this change, it would silently fail to register the plugin for use, but would load any configuration, which could have unintended effects. Fixes part of [#7264](https://togithub.com/PyCQA/pylint/issues/7264). - Fix `used-before-assignment` for functions/classes defined in type checking guard. Closes [#7368](https://togithub.com/PyCQA/pylint/issues/7368) - Update `modified_iterating` checker to fix a crash with `for` loops on empty list.

Refs [#7398](https://togithub.com/PyCQA/pylint/issues/7398) - Fix false positive for `unused-variable` and `unused-import` when a name is only used in a string literal type annotation. Closes [#3299](https://togithub.com/PyCQA/pylint/issues/3299) - Fix false positive for `too-many-function-args` when a function call is assigned to a class attribute inside the class where the function is defined. Closes [#6592](https://togithub.com/PyCQA/pylint/issues/6592) - Fix `used-before-assignment` for functions/classes defined in type checking guard. Closes [#7368](https://togithub.com/PyCQA/pylint/issues/7368) - Fix ignored files being linted when passed on stdin. Closes [#4354](https://togithub.com/PyCQA/pylint/issues/4354) - `missing-return-doc`, `missing-raises-doc` and `missing-yields-doc` now respect the `no-docstring-rgx` option. Closes [#4743](https://togithub.com/PyCQA/pylint/issues/4743) - Don't crash on `OSError` in config file discovery. Closes [#7169](https://togithub.com/PyCQA/pylint/issues/7169) - `disable-next` is now correctly scoped to only the succeeding line. Closes [#7401](https://togithub.com/PyCQA/pylint/issues/7401) - Update `modified_iterating` checker to fix a crash with `for` loops on empty list. Closes [#7380](https://togithub.com/PyCQA/pylint/issues/7380) ### [`v2.15.0`](https://togithub.com/PyCQA/pylint/releases/tag/v2.15.0) [Compare Source](https://togithub.com/PyCQA/pylint/compare/v2.14.5...v2.15.0) In pylint 2.15.0, we added a new check `missing-timeout` to warn of default timeout values that could cause a program to be hanging indefinitely. We improved `pylint`'s handling of namespace packages. More packages should be linted without resorting to using the `--recursive=y` option. We still welcome any community effort to help review, integrate, and add good/bad examples to the doc for [https://github.com/PyCQA/pylint/issues/5953](https://togithub.com/PyCQA/pylint/issues/5953). This should be doable without any `pylint` or `astroid` knowledge, so this is the perfect entrypoint if you want to contribute to `pylint` or open source without any experience with our code! Internally, we changed the way we generate the release notes, thanks to DudeNr33. There will be no more conflict resolution to do in the changelog, and every contributor rejoice. Marc Byrne became a maintainer, welcome to the team ! ## New Checks - Added new checker `missing-timeout` to warn of default timeout values that could cause a program to be hanging indefinitely.
