##### RC

A Release Candidate (RC) is a near-final software version, stable but undergoing last tests before official release. It has all features and no known bugs.

* Users: Use cautiously due to potential undiscovered bugs. Not for critical systems unless prepared for issues. Report bugs.
* Developers/Testers: Perform crucial final validation and thorough testing, especially of recent changes, to catch last-minute major issues.
* Backup: Always back up data before installing an RC to allow rollback if problems arise.
* Feedback: Provide feedback; it's vital for a robust final release.

> [!NOTE]
> Keep a backup of the last stable database as you will be unable to update from a RC to the next stable version. Database migrations may change between release candidates and stable versions.
