================ Release timeline ================ There are approximately three stable releases a year. Every other release is a LTS (Long Term Support). A LTS release is supported for 18 months. A stable release that is not LTS is supported until the next stable release is published. A development / testing release is not supported. * Long Term Support release : 18 months * Stable release : until the next stable release is published * Development / testing release : not supported Supporting a release means: * `Integration and upgrade tests `_ are run on a regular basis and `their results `_ analyzed by Ceph developers. * `Issues `_ fixed in the development branch is scheduled to be backported to the release. * When an issue found in the release is `reported `_ it will be handled by Ceph developers. * The `stable releases and backport team `_ publishes ``point releases`` including fixes that have been backported to the release. In the following, the life time of a LTS is calculated to be 18 months after the month of the first release. For instance, Dumpling is published August 2013 and 18 months starting September 2013 is February 2015, therefore by March 2015 Dumpling should be End of Life. The lifetime of a release may be extended a few months. For instance although Dumpling theoritical End of Life was March 2015, it was extended to May 2015. There is no estimated End of Life for a stable release that is not a LTS because it is set by the release date of the next stable release instead of a fixed duration.
