   - Fail2ban 0.11 is totally compatible to 0.10, but the database got some new tables and fields (auto-converted during the first start),
     so once updated to DMS 10.0.0, you have to remove the database `mailstate:/lib-fail2ban/fail2ban.sqlite3` if you would need to downgrade to DMS 9.1.0 for some reason.
-- **[general]** Removed `stable` (#1975)

   - scheduled build is now based on `edge`

   - `stable` image tag will be removed from dockerhub in near future
