Rename the Release Cycle page to "Maintenance and Support" and add a table of the Kubernetes and Ceph versions supported by each Rook minor release series (1.12 through 1.20). The per-series numbers are sourced from each release branch's prerequisites/quickstart guide (Kubernetes) and Ceph upgrade guide (Ceph), giving users a single place to check version compatibility across releases. A redirect preserves the previous release-cycle URL. Signed-off-by: Joshua Hoblitt <josh@hoblitt.com>

# Maintenance and Support
|
||
|
||
Rook plans to release a new minor version three times a year, or about every four months.
|
||
|
||
The most recent two minor Rook releases are actively maintained.
|
||
|
||
Patch releases for the latest minor release are typically bi-weekly.
|
||
Urgent patches may be released sooner.
|
||
|
||
Patch releases for the previous minor release are commonly monthly, though will vary
|
||
depending on the urgency of fixes.
|
||
|
||
## Definition of Maintenance
|
||
|
||
The Rook community defines maintenance in that relevant bug fixes that are merged to the main
|
||
development branch will be eligible to be back-ported to the release branch of any currently
|
||
maintained version. Patches will be released as needed. It is also possible that a fix may
|
||
be merged directly to the release branch if no longer applicable on the main development branch.
|
||
|
||
While Rook maintainers make significant efforts to release urgent issues in a timely manner,
|
||
maintenance does not indicate any SLA on response time.
|
||
|
||
## Supported Versions
|
||
|
||
The following Kubernetes and Ceph versions are supported by each Rook minor release series. For
|
||
the current release, the authoritative sources are the
|
||
[Prerequisites](Prerequisites/prerequisites.md) (Kubernetes) and the
|
||
[Ceph Upgrade](../Upgrade/ceph-upgrade.md#supported-versions) guide (Ceph).
|
||
|
||

### Notes
|
||
|
||
* The table records the versions each series supported at release. Patch
|
||
releases occasionally extend support; consult the documentation for the
|
||
specific release for the definitive list.
|
||
* Only the most recent two minor Rook releases are actively maintained. Older
|
||
series are listed for reference.
|
||
* Rook expects to support the most recent six versions of Kubernetes. While
|
||
these K8s versions may not all be supported by the K8s release cycle, we
|
||
understand that clusters may take time to update.
|
||
* Ceph Tentacle v20.2.0 is not recommended due to a known data-corruption issue
|
||
when the "read affinity" feature is enabled. Use v20.2.1 or newer. See the
|
||
[Ceph Upgrade](../Upgrade/ceph-upgrade.md#supported-versions) guide for
|
||
details.
