 286 Understanding the release cycle
 287 -------------------------------
 288
 289 The development release cycle is two to four weeks long.  Each cycle
 290 freezes the master development branch and applies `integration and
 291 upgrade tests <https://github.com/ceph/ceph-qa-suite>`_ for the
 292 duration of one cycle before it is released and the next release's
 293 code is frozen for testing.  Once released, there is no effort to
 294 backport fixes; developer focus in on the next development release
 295 which is usually only a few weeks away.
 296
 297 There are three to four stable releases a year.  Each stable release
 298 will receive a name (e.g., 'Jewel') and bug fix backports at least
 299 until the next stable release is out.
 300
 301 Every other stable releases is a LTS (Long Term Stable) and will
 302 receive updates until two LTS are published. For instance Dumpling is
 303 retired when Hammer is published, Firefly is retired when Jewel is
 304 published etc. The rationale is that backports to a LTS (Firefly for
 305 instance) are expected to happen until the next LTS is published
 306 (Jewel is the LTS following Hammer), to fix bugs and possibly
 307 backport important features. After the next LTS is published,
 308 backports are still expected to fix bugs with a focus on whatever can
 309 prevent upgrades to the next LTS (in our example, fixes to Dumpling
 310 were published after Firefly was released and until Hammer was
 311 published, primarily to ensure Dumpling cluster can smoothly migrate
 312 to Firefly).
 313
 314 * Long Term Stable : until the next two LTS are published
 315 * Stable release : until the next stable release is published
 316 * Development / testing release : no backports
 317
 318 For each stable release:
 319
 320 * `Integration and upgrade tests
 321   <https://github.com/ceph/ceph-qa-suite>`_ are run on a regular basis
 322   and `their results <http://pulpito.ceph.com/>`_ analyzed by Ceph
 323   developers.
 324 * `Issues <http://tracker.ceph.com/projects/ceph/issues?query_id=27>`_
 325   fixed in the development branch (master) are scheduled to be backported.
 326 * When an issue found in the stable release is `reported
 327   <http://tracker.ceph.com/projects/ceph/issues/new>`_, it is
 328   triaged by Ceph developers.
 329 * The `stable releases and backport team <http://tracker.ceph.com/projects/ceph-releases>`_
 330   publishes ``point releases`` including fixes that have been backported to the stable release.
 331
 332 In the timeline, the life time of a LTS is calculated to be
 333 approximately 18 months after the month of the first release. For
 334 instance, Dumpling is published August 2013 and 18 months starting
 335 September 2013 is February 2015, therefore by March 2015 Dumpling
 336 should be retired. The lifetime of a release may vary because it
 337 depend on how quickly the stable releases are published. For instance
 338 although Dumpling theoritical retirement was March 2015, it was
 339 extended to May 2015.
 340
 341 Release numbers conventions
 342 ---------------------------
 343
 344 The first Ceph release back in Jan of 2008 was 0.1.  That made sense at
 345 the time.  The versioning scheme did not change until April 2015,
 346 when 0.94.1 (the first Hammer point release) was published.  To avoid reaching
 347 0.99 (and 0.100 or 1.00?) we have a new strategy.
 348
 349 * x.0.z - development releases (for early testers and the brave at heart)
 350 * x.1.z - release candidates (for test clusters, brave users)
 351 * x.2.z - stable/bugfix releases (for users)
 352
 353 ``x`` will start at 9 for Infernalis (``I`` is the 9th letter), making
 354 our first development release of the 9th release cycle 9.0.0.
 355 Subsequent development releases will be 9.0.1, 9.0.2, etc.
 356
 357 After a couple months we'll have a 9.1.0 (and maybe 9.1.1) release candidate.
 358
 359 A few weeks after that we'll have the Infernalis release 9.2.0, followed
 360 by stable bug fix updates 9.2.1, 9.2.2, etc., and then begin work on the
 361 Jewel (10.y.z) release.
