 Summary -- Release highlights
 =============================
@@ -17,4 +17,169 @@ 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>`_. 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 !

+  changelog anymore.
+
+  Closes #6974 (`#6974 <https://github.com/PyCQA/pylint/issues/6974>`_)
+- Pylint is now using Scorecards to implement security recommendations from the
+  `OpenSSF <https://openssf.org/>`_. This is done in order to secure our supply chains using a combination
+  of automated tooling and best practices, most of which were already implemented before.
