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/.

 h3. Leads 

 * Ceph: Ceph : Sage Weil 
 * RADOS: rados : Josh Durgin 
 * RGW: Casey Bodley radosgw / rgw : Yehuda Sadeh 
 * CephFS: CephFS / fs : Patrick Donnelly
