Understanding the release cycle
Starting with the Nautilus release (14.2.0), there is a new stable release cycleevery year, targeting March 1st. Each stable release series will receive a name(e.g., ‘Mimic’) and a major release number (e.g., 13 for Mimic because ‘M’ isthe 13th letter of the alphabet).
Releases are named after a species of cephalopod (usually the commonname, since the latin names are harder to remember or pronounce).
Version numbers have three components, x.y.z. x identifies the releasecycle (e.g., 13 for Mimic). y identifies the release type:
x.0.z - development releases (for early testers and the brave at heart)
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 tothat, versions looked with 0.y for development releases and 0.y.z for stableseries.
Development releases (x.0.z)
Each development release (x.0.z) freezes the master development branchand applies integration and upgrade tests before it is released. Oncereleased, there is no effort to backport fixes; developer focus is onthe 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 previousdevelopment releases (meaning you can stop all daemons, upgrade, andrestart). No attempt is made to support online rolling upgradesbetween development releases. This facilitates deployment ofdevelopment releases on non-production test clusters withoutrepopulating them with data.
Release candidates (x.1.z)
There is a feature release roughly eight (8) weeks prior to the plannedinitial stable release, after which focus shifts to stabilization andbug fixes only.
Release candidate release every 1-2 weeks
Intended for final testing and validation of the upcoming stable release
Stable releases (x.2.z)
Once the initial stable release is made (x.2.0), there aresemi-regular bug-fix point releases with bug fixes and (occasionally)small feature backports. Bug fixes are accumulated and included inthe next point release.
Stable point release every 4 to 6 weeks
Intended for production deployments
Bug fix backports for two full release cycles.
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 pointreleases
For each stable release:
Integration and upgrade tests are run on a regular basisand their results analyzed by Cephdevelopers.
Issuesfixed in the development branch (master) are scheduled to be backported.
When an issue found in the stable release is reported, it istriaged by Ceph developers.
The stable releases and backport teampublishes
point releasesincluding fixes that have been backported to the stable release.
Lifetime of stable releases
The lifetime of a stable release series is calculated to be approximately 24months (i.e., two 12 month release cycles) after the month of the first release.For example, Mimic (13.2.z) will reach end of life (EOL) shortly after Octopus(15.2.0) is released. The lifetime of a release may vary because it depends onhow quickly the stable releases are published.
In the case of Jewel and Kraken, the lifetime was slightly different thandescribed above. Prior to Luminous, only every other stable release was an “LTS”release. Therefore,
Upgrade scenarios “Jewel -> Kraken -> Luminous” and “Jewel -> Luminous” wereexpected to work.
Upgrades from Jewel or Kraken must upgrade to Luminous first before proceedingfurther (e.g., Kraken -> Luminous -> Mimic but not Kraken -> Mimic).
Jewel was maintained until Mimic was released (June 2018).
Kraken is no longer maintained.
