Ceph » Stable releases

h3. Introduction

Backporting and the maintenance of a stable release begins when a new "stable Ceph release":http://ceph.com/docs/master/releases 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":http://ceph.com/docs/master/releases is published. This repeats until the "the stable release is retired":http://ceph.com/docs/master/releases. Backporting is focused on fixing bugs and development on the master branch is expected to add new features but both share the "same workflow":http://ceph.com/docs/master/dev/development-workflow/.
