What’s in this release
- Security fixes and hardening: fixes for reported vulnerabilities, authentication improvements (2FA/SSO guidance) and tightened security headers and content-security-policy.
- Files, sharing and collaboration improvements: performance optimisations for the Files app, improved file locking and preview generation, and refined sharing and federation behaviour.
- Developer, API and app compatibility changes: API changes and deprecations, updated hooks/events and guidance for app migration and compatibility testing.
Upgrade notes
- Check minimum system requirements (PHP, database and webserver) and follow the pre-upgrade checklist: backups, maintenance mode and app compatibility checks; follow the step-by-step upgrade guidance in the release notes.
- Rollback guidance and migration caveats are provided for federation, external storage and high-availability setups — keep recent backups and test upgrades in a staging environment before applying to production.
