Understanding the release cycle
-------------------------------
Starting with the Nautilus release (14.2.0), there is a new stable release cycle
-every year, targeting March 1st. Each stable release series will receive a name
+every year, targeting the month of March. Each stable release series will receive a name
(e.g., 'Mimic') and a major release number (e.g., 13 for Mimic because 'M' is
the 13th letter of the alphabet).
Version numbers have three components, *x.y.z*. *x* identifies the release
cycle (e.g., 13 for Mimic). *y* identifies the release type:
-* x.0.z - development releases (for early testers and the brave at heart)
+* x.0.z - development versions
* x.1.z - release candidates (for test clusters, brave users)
* x.2.z - stable/bugfix releases (for users)
-This versioning convention started with the 9.y.z Infernalis cycle. Prior to
-that, versions looked with 0.y for development releases and 0.y.z for stable
-series.
-
-Development releases (x.0.z)
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Each development release (x.0.z) freezes the master development branch
-and applies `integration and upgrade tests
-<https://github.com/ceph/ceph/tree/master/qa/suites/>`_ before it is released. Once
-released, there is no effort to backport fixes; developer focus is on
-the next development release which is usually only a few weeks away.
-
-* Development release every 8 to 12 weeks
-* Intended for testing, not production deployments
-* Full integration testing
-* Upgrade testing from the last stable release(s)
-* Every effort is made to allow *offline* upgrades from previous
- development releases (meaning you can stop all daemons, upgrade, and
- restart). No attempt is made to support online rolling upgrades
- between development releases. This facilitates deployment of
- development releases on non-production test clusters without
- repopulating them with data.
-
Release candidates (x.1.z)
^^^^^^^^^^^^^^^^^^^^^^^^^^
-There is a feature release roughly eight (8) weeks prior to the planned
+There is a feature freeze roughly two months prior to the planned
initial stable release, after which focus shifts to stabilization and
bug fixes only.
Once the initial stable release is made (x.2.0), there are
semi-regular bug-fix point releases with bug fixes and (occasionally)
-small feature backports. Bug fixes are accumulated and included in
+feature backports. Bug fixes are accumulated and included in
the next point release.
* Stable point release every 4 to 6 weeks
* Intended for production deployments
-* Bug fix backports for two full release cycles.
+* Bug fix backports for 2 full release cycles (2 years).
* Online, rolling upgrade support and testing from the last two (2)
stable release(s) (starting from Luminous).
* Online, rolling upgrade support and testing from prior stable point
(15.2.0) is released. The lifetime of a release may vary because it depends on
how quickly the stable releases are published.
-In the case of Jewel and Kraken, the lifetime was slightly different than
-described above. Prior to Luminous, only every other stable release was an "LTS"
-release. Therefore,
-
-* Upgrade scenarios "Jewel -> Kraken -> Luminous" and "Jewel -> Luminous" were
- expected to work.
-* Upgrades from Jewel or Kraken must upgrade to Luminous first before proceeding
- further (e.g., Kraken -> Luminous -> Mimic but not Kraken -> Mimic).
-* Jewel was maintained until Mimic was released (June 2018).
-* Kraken is no longer maintained.
