-Rolling release for nextcloud-33: the image is pinned to `nextcloud:33-fpm` (no minor/patch), so it follows the latest 33.x. This is the last release before moving to nextcloud-34.
+Upgrades Nextcloud from 33 to 34 (major version upgrade).
+
+IMPORTANT:
+- Do not skip major versions: your instance must be on the latest 33.x before
+  upgrading to 34. If you are on an older 33.x, deploy 33.0.9 first.
+- Use `check_major_upgrade` (`abra app cmd <app-name> app check_major_upgrade`) 
+  to check whether an instance is ready to upgrade to the next Nextcloud 
+  major version.
+- Nextcloud does NOT support downgrades. Take a backup before deploying.
+- After deploying, check the logs and run any pending repair/upgrade steps:
+  `abra app cmd <app> app run_occ '"app:update --all"'`
+- Review app (plug-in) compatibility with Nextcloud 34 before upgrading; some
+  apps may need to be updated or temporarily disabled.
