  [ Otto Kekäläinen ]
  * New upstream maintenance release 11.8.3. For details about fixes please see
    https://mariadb.com/kb/en/mariadb-11-8-3-release-notes/
  * Drop Hurd patches that are now included upstream
  * Update configuration traces to include new upstream system variables:
    - analyze-max-length (default: 4294967295)
    - innodb-linux-aio (default: auto)
  * Suppress new native AIO warning introduced in upstream a87bb96 to avoid
    mariadb-test-run failing on on something that isn't a real issue
  * New upstream release includes fix for MDEV-36815 that yielded "ERROR 1267
    (HY000): Illegal mix of collations" on some systems when restarting the
    MariaDB service in Debian (Closes: #1104533)
  * Remove obsolete cleanup as upstream moved pam_mariadb_mtr.so in c05b1fe
  * Salsa CI: Use full MariaDB package set in Bookworm MariaDB 10.6 upgrade
  * Salsa CI: Automatically use archive.d.o for discontinued releases

  [ Lena Voytek ]
  * Do not hardcode libxml2 dependency in mariadb-plugin-connect
    (Closes: #1106889)

I am not aware of any additional Debian tracked bugs at https://bugs.debian.org/cgi-bin/pkgreport.cgi?repeatmerged=no&src=mariadb that would be fixed by this version.

I did not spot any new CVEs at https://mariadb.com/docs/server/security that would apply for this version, thus there are no CVE entries in the changelog either.

Note also test builds on multiple architectures at https://launchpad.net/~mysql-ubuntu/+archive/ubuntu/mariadb/+builds?build_text=&build_state=all
