# Release Cycle
|
|
|
|
|
|
|
|
|
|
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be merged directly to the release branch if no longer applicable on the main development branch.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.

## K8s Versions
|
|
|
|
|
|
|
|
|
|
The minimum version supported by a Rook release is specified in the
|
|
|
|
|
[Quickstart Guide](quickstart.md#minimum-version).
|
|
|
|
|
|
|
|
|
|
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.
