 :Release: 2.9

 Summary -- Release highlights
 =============================
 
+Pylint is now compatible with python 3.10.
+
+A lot of new checks have been added, some non-opinionated performance warnings
+like ``use-maxsplit-arg``, some consensual style warnings like
+``unnecessary-dict-index-lookup`` or new deprecation checks.
+
+We're aiming to reduce pylint noise for first time users and making some
+new checks optional is a step in that direction. In order to do that we
+created an optional code style checker that can be loaded using
+``pylint.extensions.code_style`` with the ``load-plugins`` options.
+More than ever, if as a veteran you want the most checks you can possibly get,
+[you should check the list of pylint extensions.](http://pylint.pycqa.org/en/latest/technical_reference/extensions.html#optional-pylint-checkers-in-the-extensions-module).
