+Release Summary
+---------------
+
+This is the minor release of the ``community.mysql`` collection.
+This changelog contains all changes to the modules and plugins in this collection
+that have been made after the previous release.
+
+Minor Changes
+-------------
+
+- mysql_info - add ``connector_name`` and ``connector_version`` to returned values (https://github.com/ansible-collections/community.mysql/pull/497).
+- mysql_role - enable auto_commit to avoid MySQL metadata table lock (https://github.com/ansible-collections/community.mysql/issues/479).
+- mysql_user - add plugin_auth_string as optional parameter to use a specific pam service if pam/auth_pam plugin is used (https://github.com/ansible-collections/community.mysql/pull/445).
+- mysql_user - add the ``session_vars`` argument to set session variables at the beginning of module execution (https://github.com/ansible-collections/community.mysql/issues/478).
+- mysql_user - display a more informative invalid privilege exception. Changes the exception handling of the granting permission logic to show the query executed , params and the exception message granting privileges fails` (https://github.com/ansible-collections/community.mysql/issues/465).
+- mysql_user - enable auto_commit to avoid MySQL metadata table lock (https://github.com/ansible-collections/community.mysql/issues/479).
+- setup_mysql - update MySQL tarball URL (https://github.com/ansible-collections/community.mysql/pull/491).
+
+Bugfixes
+--------
+
+- mysql_user - when revoke privs consists only of ``GRANT``, a 2nd revoke query is executed with empty privs to revoke that ended in an SQL exception (https://github.com/ansible-collections/community.mysql/pull/503).
+- mysql_variables - add uppercase character pattern to regex to allow GLOBAL variables containing uppercase characters. This recognizes variable names used in Galera, for example, ``wsrep_OSU_method``, which breaks the normal pattern of all lowercase characters (https://github.com/ansible-collections/community.mysql/pull/501).

 - mysql_user - remove support for the `REQUIRESSL` special privilege as it has ben superseded by the `tls_requires` option (https://github.com/ansible-collections/community.mysql/discussions/121).
 - mysql_user - validate privileges using database engine directly (https://github.com/ansible-collections/community.mysql/issues/234 https://github.com/ansible-collections/community.mysql/pull/243). Do not validate privileges in this module anymore.
