Nextcloud v33.0.3 is out now. Administrators and users benefit from security hardening to authentication, sharing and remote/WebDAV surfaces and a set of stability fixes for uploads, previews and background jobs.
See the full changelog and upgrade instructions on the GitHub release page: https://github.com/nextcloud-releases/server/releases/tag/v33.0.3
What’s in this release
- Security hardening and fixes targeting authentication, sharing and remote/WebDAV surfaces.
- Bug fixes improving file handling, background jobs, previews, more reliable uploads (including resumable transfers), fewer client sync errors, and fixes around file locking and quota enforcement.
- Distribution packages and Docker images updated in sync; no breaking schema migrations for most setups, with deployment and operational notes for object stores, Redis and external storage connectors.
Upgrade notes
- Treat this as a priority upgrade: take backups of database, data and config; enable maintenance mode; apply the release via your packaging method or update the instance code; run
occ upgradeas the web server user; then disable maintenance mode and monitor logs for authentication or sharing-related errors. - If you must roll back, restore database, data and config from backups and verify connectors (object stores, Redis, external storage) and caches are healthy before returning the instance to service.
Share your upgrade experience or report issues on the GitHub release thread so other admins can benefit from any findings.
