If something problematic occurs, you +may want to roll-back to a previous version of Synapse. Because v1.26.0 also +includes a new database schema version, reverting that version is also required +alongside the generic rollback instructions mentioned above. In short, to roll +back to v1.25.0 you need to: + +1. Stop the server +2. Decrease the schema version in the database: + + .. code:: sql + + UPDATE schema_version SET version = 58; + +3. Delete the ignored users data: + + If using PostgreSQL: + + .. code:: sql + + TRUNCATE TABLE ignored_users; + + If using SQLite: + + .. code:: sql + + DELETE FROM ignored_users; + +4. Mark the ignored user delta as not run (so it will re-run on upgrade). + + .. code:: sql + + DELETE FROM applied_schema_deltas WHERE version = 59 AND file = "59/01ignored_user.py"; + +5. Downgrade Synapse by following the instructions for your installation method + in the "Rolling back to older versions" section above. + Upgrading to v1.25.0 ==================== |
