-`owncloud/server:10` tracks the 10.x line. `latest` points at the same
-release today, but ownCloud now also publishes 11.x, and a move to a new major
-should be a deliberate upgrade with a backup, not a side effect of a pull.
+`owncloud/server:11` tracks the 11.x line, so patch releases arrive on the next
+deploy and a move to a new major stays a deliberate upgrade. ownCloud's own
+compose pins a full version instead.
 
-`mariadb:12` and `redis:6` track their major versions. A MariaDB data
-directory cannot move back to an older major, so back up the database volume
-before changing it.
+`mariadb:10.11` is the release ownCloud 11's compose uses and the top of the
+MariaDB range ownCloud supports (10.2 to 10.11); a newer major is outside it.
+`MARIADB_AUTO_UPGRADE=1`, also from ownCloud's compose, runs `mariadb-upgrade`
+when the server version changes. A MariaDB data directory cannot move back to
+an older major, so going down a version means a dump and restore into an empty
+volume, not an image change. Back up `db-data` before changing the tag.
+
+`redis:7` is the version ownCloud's compose uses.
+
+ownCloud 11 runs on PHP 8. Apps installed into `/mnt/data/apps` from the
+marketplace under 10.x were built for PHP 7, so they are removed or replaced
+with PHP 8 versions before moving a 10.x install to 11.
