 Summary -- Release highlights
 =============================
 
+With 2.14 ``pylint`` only supports Python version 3.7.2 and above.
+
+We introduced several new checks among which ``duplicate-value`` for sets,
+``comparison-of-constants``, and checks related to lambdas. We removed ``no-init`` and
+made ``no-self-use`` optional as they were too opinionated. We also added an option
+to generate a toml configuration: ``--generate-toml-config``.
+
+We migrated to ``argparse`` from ``optparse`` and refactored the configuration handling
+thanks to Daniël van Noord. On the user side it should change the output of the
+``--help`` command, and some inconsistencies and bugs should disappear. The behavior
+between options set in a config file versus on the command line will be more consistent. For us,
+it will permit to maintain this part of the code easily in the future and anticipate
+``optparse``'s removal in Python 3.12.
+
+As a result of the refactor there are a lot of internal deprecations. If you're a library
+maintainer that depends on pylint, please verify that you're ready for pylint 3.0
+by activating deprecation warnings.
+
+We continued the integration of ``pylint-error`` and are now at 33%!. We still welcome any community effort
+to help review, integrate, and add good/bad examples <https://github.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!
