Ceph » Stable releases

Introduction¶

Backporting and the maintenance of a stable release begins when a new stable Ceph release is published. Commits from the master branch are cherry-picked to the stable branch and run through integration and upgrade tests. After a few weeks a point release is published. This repeats until the lifetime of the stable release comes to an end. Backporting is focused on fixing bugs and development on the master branch is expected to add new features but both share the same workflow.

The following describes in detail and in chronological order, the steps to follow for backporting and maintaining stable releases.
