 Summary -- Release highlights
 =============================

 .. towncrier release notes start
+
+What's new in Pylint 3.3.0?
+---------------------------
+Release date: 2024-09-20
+
+
+Changes requiring user actions
+------------------------------
+
+- We migrated ``symilar`` to argparse, from getopt, so the error and help output changed
+  (for the better). We exit with 2 instead of sometime 1, sometime 2. The error output
+  is not captured by the runner anymore. It's not possible to use a value for the
+  boolean options anymore (``--ignore-comments 1`` should become ``--ignore-comments``).
+
+  Refs #9731 (`#9731 <https://github.com/pylint-dev/pylint/issues/9731>`_)
+
+
+
+New Features
+------------
+
+- Add new `declare-non-slot` error which reports when a class has a `__slots__` member and a type hint on the class is not present in `__slots__`.
+
+  Refs #9499 (`#9499 <https://github.com/pylint-dev/pylint/issues/9499>`_)
+
+
+
+New Checks
+----------
+
+- Added `too-many-positional-arguments` to allow distinguishing the configuration for too many
+  total arguments (with keyword-only params specified after `*`) from the configuration
+  for too many positional-or-keyword or positional-only arguments.
+
+  As part of evaluating whether this check makes sense for your project, ensure you
+  adjust the value of `--max-positional-arguments`.
+
+  Closes #9099 (`#9099 <https://github.com/pylint-dev/pylint/issues/9099>`_)
+
+- Add `using-exception-group-in-unsupported-version` and
+  `using-generic-type-syntax-in-unsupported-version` for uses of Python 3.11+ or
+  3.12+ features on lower supported versions provided with `--py-version`.
+
+  Closes #9791 (`#9791 <https://github.com/pylint-dev/pylint/issues/9791>`_)
+
+- Add `using-assignment-expression-in-unsupported-version` for uses of `:=` (walrus operator)
+  on Python versions below 3.8 provided with `--py-version`.
+
+  Closes #9820 (`#9820 <https://github.com/pylint-dev/pylint/issues/9820>`_)
+
+- Add `using-positional-only-args-in-unsupported-version` for uses of positional-only args on
+  Python versions below 3.8 provided with `--py-version`.
+
+  Closes #9823 (`#9823 <https://github.com/pylint-dev/pylint/issues/9823>`_)
+
+- Add ``unnecessary-default-type-args`` to the ``typing`` extension to detect the use
+  of unnecessary default type args for ``typing.Generator`` and ``typing.AsyncGenerator``.
+
+  Refs #9938 (`#9938 <https://github.com/pylint-dev/pylint/issues/9938>`_)
+
+
+
+False Negatives Fixed
+---------------------
+
+- Fix computation of never-returning function: `Never` is handled in addition to `NoReturn`, and priority is given to the explicit `--never-returning-functions` option.
+
+  Closes #7565. (`#7565 <https://github.com/pylint-dev/pylint/issues/7565>`_)
+
+- Fix a false negative for `await-outside-async` when await is inside Lambda.
+
+  Refs #9653 (`#9653 <https://github.com/pylint-dev/pylint/issues/9653>`_)
+
+- Fix a false negative for ``duplicate-argument-name`` by including ``positional-only``, ``*args`` and ``**kwargs`` arguments in the check.
+
+  Closes #9669 (`#9669 <https://github.com/pylint-dev/pylint/issues/9669>`_)
+
+- Fix false negative for `multiple-statements` when multiple statements are present on `else` and `finally` lines of `try`.
+
+  Refs #9759 (`#9759 <https://github.com/pylint-dev/pylint/issues/9759>`_)
+
+- Fix false negatives when `isinstance` does not have exactly two arguments.
+  pylint now emits a `too-many-function-args` or `no-value-for-parameter`
+  appropriately for `isinstance` calls.
+
+  Closes #9847 (`#9847 <https://github.com/pylint-dev/pylint/issues/9847>`_)
+
+
+
+Other Bug Fixes
+---------------
+
+- `--enable` with `--disable=all` now produces an error, when an unknown msg code is used. Internal `pylint` messages are no longer affected by `--disable=all`.
+
+  Closes #9403 (`#9403 <https://github.com/pylint-dev/pylint/issues/9403>`_)
+
+- Impossible to compile regexes for paths in the configuration or argument given to pylint won't crash anymore but
+  raise an argparse error and display the error message from ``re.compile`` instead.
+
+  Closes #9680 (`#9680 <https://github.com/pylint-dev/pylint/issues/9680>`_)
+
+- Fix a bug where a ``tox.ini`` file with pylint configuration was ignored and it exists in the current directory.
+
+  ``.cfg`` and ``.ini`` files containing a ``Pylint`` configuration may now use a section named ``[pylint]``. This enhancement impacts the scenario where these file types are used as defaults when they are present and have not been explicitly referred to, using the ``--rcfile`` option.
+
+  Closes #9727 (`#9727 <https://github.com/pylint-dev/pylint/issues/9727>`_)
+
+- Improve file discovery for directories that are not python packages.
+
+  Closes #9764 (`#9764 <https://github.com/pylint-dev/pylint/issues/9764>`_)
+
+
+
+Other Changes
+-------------
+
+- Remove support for launching pylint with Python 3.8.
+  Code that supports Python 3.8 can still be linted with the ``--py-version=3.8`` setting.
+
+  Refs #9774 (`#9774 <https://github.com/pylint-dev/pylint/issues/9774>`_)
+
+- Add support for Python 3.13.
+
+  Refs #9852 (`#9852 <https://github.com/pylint-dev/pylint/issues/9852>`_)
+
+
+
+Internal Changes
+----------------
+
+- All variables, classes, functions and file names containing the word 'similar', when it was,
+  in fact, referring to 'symilar' (the standalone program for the duplicate-code check) were renamed
+  to 'symilar'.
+
+  Closes #9734 (`#9734 <https://github.com/pylint-dev/pylint/issues/9734>`_)
+
+- Remove old-style classes (Python 2) code and remove check for new-style class since everything is new-style in Python 3. Updated doc for exception checker to remove reference to new style class.
+
+  Refs #9925 (`#9925 <https://github.com/pylint-dev/pylint/issues/9925>`_)
