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
|
|
<https://github.com/ceph/ceph-qa-suite>`_ are run on a regular basis
|
|
and `their results <http://pulpito.ceph.com/>`_ analyzed by Ceph
|
|
developers.
|
|
* `Issues <http://tracker.ceph.com/projects/ceph/issues?query_id=27>`_
|
|
fixed in the development branch is scheduled to be backported to the
|
|
release.
|
|
* When an issue found in the release is `reported
|
|
<http://tracker.ceph.com/projects/ceph/issues/new>`_ it will be
|
|
handled by Ceph developers.
|
|
* The `stable releases and backport team <http://tracker.ceph.com/projects/ceph-releases>`_
|
|
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.
