| 12 | +# Kubernetes Patch Releases |
| 13 | + |
| 14 | +Schedule and team contact information for Kubernetes patch releases. |
| 15 | + |
| 16 | +For general information about Kubernetes release cycle, see the |
| 17 | +[release process description]. |
| 18 | + |
| 19 | +## Cadence |
| 20 | + |
| 21 | +Our typical patch release cadence is monthly. It is |
| 22 | +commonly a bit faster (1 to 2 weeks) for the earliest patch releases |
| 23 | +after a 1.X minor release. Critical bug fixes may cause a more |
| 24 | +immediate release outside of the normal cadence. We also aim to not make |
| 25 | +releases during major holiday periods. |
| 26 | + |
| 27 | +## Contact |
| 28 | + |
| 29 | +See the [Release Managers page][release-managers] for full contact details on the Patch Release Team. |
| 30 | + |
| 31 | +Please give us a business day to respond - we may be in a different timezone! |
| 32 | + |
| 33 | +In between releases the team is looking at incoming cherry-pick |
| 34 | +requests on a weekly basis. The team will get in touch with |
| 35 | +submitters via GitHub PR, SIG channels in Slack, and direct messages |
| 36 | +in Slack and [email ](mailto:[email protected]) |
| 37 | +if there are questions on the PR. |
| 38 | + |
| 39 | +## Cherry-Picks |
| 40 | + |
| 41 | +Please follow the [cherry-pick process]. |
| 42 | + |
| 43 | +Cherry-picks must be merge-ready in GitHub with proper labels (eg: |
| 44 | +approved, lgtm, release note) and passing CI tests ahead of the |
| 45 | +cherry-pick deadline. This is typically two days before the target |
| 46 | +release, but may be more. Earlier PR readiness is better, as we |
| 47 | +need time to get CI signal after merging your cherry-picks ahead |
| 48 | +of the actual release. |
| 49 | + |
| 50 | +Cherry-pick PRs which miss merge criteria will be carried over and tracked |
| 51 | +for the next patch release. |
| 52 | + |
| 53 | +## Support Period |
| 54 | + |
| 55 | +In accordance with the [yearly support KEP][yearly-support], the Kubernetes |
| 56 | +Community will support active patch release series for a period of roughly |
| 57 | +fourteen (14) months. |
| 58 | + |
| 59 | +The first twelve months of this timeframe will be considered the standard |
| 60 | +period. |
| 61 | + |
| 62 | +Towards the end of the twelve month, the following will happen: |
| 63 | + |
| 64 | +- [Release Managers][release-managers] will cut a release |
| 65 | +- The patch release series will enter maintenance mode |
| 66 | + |
| 67 | +During the two-month maintenance mode period, Release Managers may cut |
| 68 | +additional maintenance releases to resolve: |
| 69 | + |
| 70 | +- CVEs (under the advisement of the Product Security Committee) |
| 71 | +- dependency issues (including base image updates) |
| 72 | +- critical core component issues |
| 73 | + |
| 74 | +At the end of the two-month maintenance mode period, the patch release series |
| 75 | +will be considered EOL (end of life) and cherry picks to the associated branch |
| 76 | +are to be closed soon afterwards. |
| 77 | + |
| 78 | +Note that the 28th of the month was chosen for maintenance mode and EOL target |
| 79 | +dates for simplicity (every month has it). |
| 80 | + |
| 81 | +## Upcoming Monthly Releases |
| 82 | + |
| 83 | +Timelines may vary with the severity of bug fixes, but for easier planning we |
| 84 | +will target the following monthly release points. Unplanned, critical |
| 85 | +releases may also occur in between these. |
| 86 | + |
