## False Positives Fixed
- Prevent emitting `possibly-used-before-assignment` when relying on names
only potentially not defined in conditional blocks guarded by functions

Closes [#9398](https://togithub.com/pylint-dev/pylint/issues/9398)

from `possibly-used-before-assignment` checks.
Closes [#9627](https://togithub.com/pylint-dev/pylint/issues/9627)
- Don't emit `typevar-name-incorrect-variance` warnings for PEP 695 style TypeVars.
The variance is inferred automatically by the type checker.
Adding `_co` or `_contra` suffix can help to reason about TypeVar.
Refs [#9638](https://togithub.com/pylint-dev/pylint/issues/9638)
- Fix a false positive for `possibly-used-before-assignment` when using
`typing.assert_never()` (3.11+) to indicate exhaustiveness.

- Fix a false negative for `--ignore-patterns` when the directory to be linted is specified using a dot(`.`) and all files are ignored instead of only the files whose name begin with a dot.
Closes [#9273](https://togithub.com/pylint-dev/pylint/issues/9273)
- Restore "errors / warnings by module" section to report output (with `-ry`).
Closes [#9145](https://togithub.com/pylint-dev/pylint/issues/9145)
- `trailing-comma-tuple` should now be correctly emitted when it was disabled globally
but enabled via local message control, after removal of an over-optimisation.
Refs [#9608](https://togithub.com/pylint-dev/pylint/issues/9608)
- Add `--prefer-stubs=yes` option to opt-in to the astroid 3.2 feature
that prefers `.pyi` stubs over same-named `.py` files. This has the
potential to reduce `no-member` errors but at the cost of more errors
such as `not-an-iterable` from function bodies appearing as `...`.
Defaults to `no`.
Closes [#9626](https://togithub.com/pylint-dev/pylint/issues/9626)
Closes [#9623](https://togithub.com/pylint-dev/pylint/issues/9623)
## Internal Changes
- Update astroid version to 3.2.1. This solves some reports of `RecursionError`
and also makes the *prefer .pyi stubs* feature in astroid 3.2.0 *opt-in*
with the aforementioned `--prefer-stubs=y` option.
Refs [#9139](https://togithub.com/pylint-dev/pylint/issues/9139)
### [`v3.2.0`](https://togithub.com/pylint-dev/pylint/releases/tag/v3.2.0)
[Compare Source](https://togithub.com/pylint-dev/pylint/compare/v3.1.1...v3.2.0)
## What's new in Pylint 3.2.0?
Release date: 2024-05-14
Of note: a `github` reporter, two new checks (`possibly-used-before-assignment` and `contextmanager-generator-missing-cleanup`), performance improvements, and an `astroid` upgrade providing support for `@overload` and `.pyi` stubs.
## New Features
- Understand `six.PY2` and `six.PY3` for conditional imports.
Closes [#3501](https://togithub.com/pylint-dev/pylint/issues/3501)
- A new `github` reporter has been added. This reporter returns the output of `pylint` in a format that
Github can use to automatically annotate code. Use it with `pylint --output-format=github` on your Github Workflows.
Closes [#9443](https://togithub.com/pylint-dev/pylint/issues/9443).
## New Checks
- Add check `possibly-used-before-assignment` when relying on names after an `if/else`
switch when one branch failed to define the name, raise, or return.
Closes [#1727](https://togithub.com/pylint-dev/pylint/issues/1727)
- Checks for generators that use contextmanagers that don't handle cleanup properly.
Is meant to raise visibilty on the case that a generator is not fully exhausted and the contextmanager is not cleaned up properly.
A contextmanager must yield a non-constant value and not handle cleanup for GeneratorExit.
The using generator must attempt to use the yielded context value `with x() as y` and not just `with x()`.
Closes [#2832](https://togithub.com/pylint-dev/pylint/issues/2832)
## False Negatives Fixed
- If and Try nodes are now checked for useless return statements as well.
Closes [#9449](https://togithub.com/pylint-dev/pylint/issues/9449).
- Fix false negative for `property-with-parameters` in the case of parameters which are `positional-only`, `keyword-only`, `variadic positional` or `variadic keyword`.
Closes [#9584](https://togithub.com/pylint-dev/pylint/issues/9584)
## False Positives Fixed
- pylint now understands the `@overload` decorator return values better.
Closes [#4696](https://togithub.com/pylint-dev/pylint/issues/4696)
Refs [#9606](https://togithub.com/pylint-dev/pylint/issues/9606)
## Performance Improvements
- Ignored modules are now not checked at all, instead of being checked and then
ignored. This should speed up the analysis of large codebases which have
ignored modules.
Closes [#9442](https://togithub.com/pylint-dev/pylint/issues/9442)
- ImportChecker's logic has been modified to avoid context files when possible. This makes it possible
to cache module searches on astroid and reduce execution times.
Refs [#9310](https://togithub.com/pylint-dev/pylint/issues/9310).
- An internal check for `trailing-comma-tuple` being enabled for a file or not is now
done once per file instead of once for each token.
Refs [#9608](https://togithub.com/pylint-dev/pylint/issues/9608).

## False Positives Fixed
- Treat `attrs.define` and `attrs.frozen` as dataclass decorators in
`too-few-public-methods` check.
Closes [#9345](https://togithub.com/pylint-dev/pylint/issues/9345)
- Fix a false positive with `singledispatchmethod-function` when a method is decorated with both `functools.singledispatchmethod` and `staticmethod`.
Closes [#9531](https://togithub.com/pylint-dev/pylint/issues/9531)
- Fix a false positive for `consider-using-dict-items` when iterating using `keys()` and then deleting an item using the key as a lookup.
Closes [#9554](https://togithub.com/pylint-dev/pylint/issues/9554)
