How to verify packages →

Running the upgrade script is required when upgrading to this release.

Before performing any upgrade please remember to backup your forum’s files and database and store them safely. If you have edited core files, including language files, please make sure you make a changelog for these changes so you can make them again (if necessary) once the upgrade is complete.

Follow the Upgrade Documentation for more detailed instructions.

Changes include added support for Mixer videos and multi-file attachments, modified Word Filter behavior, fixes to the mailing queue and improved compatibility with SQLite and MySQL 8. Theme CSS changes may be required and administrators may need to review Word Filters.
