Kubernetes 1.14: Caturnetes

Three Wolf Moon But The Wolves Are Cats And The Moon Is Kubernetes


Tracking docs



The 1.14 release cycle is proposed as follows:

  • Monday, January 07: Week 1 - Release cycle begins
  • Tuesday, January 29: Week 4 - Enhancements Freeze
  • Thursday, March 07: Week 9 - Code Freeze
  • Monday, March 18: Week 11 - Docs must be completed and reviewed
  • Monday, March 25: Week 12 - Kubernetes v1.14.0 released

What Will We Do Differently This Release?

  • All proposed Enhancements for this release must have an associated KEP.
    • There are no exceptions; if the enhancement had no associated KEP before, it must have one now.
    • The KEP must have a checklist of requirements necessary for a feature to land as alpha, beta, or stable. That checklist must have at a minimum a test plan, and an upgrade/downgrade plan.
  • There will be no Code Slush.
    • Previous release teams have said the only value of Code Slush was a clear one week warning that Code Freeze is coming
    • Use the start of Burndown meetings as that date if you need it

Enhancements Freeze

By Tuesday January 29, 2019 all enhancements landing in v1.14.0 must:

By Monday, February 4, 2019, the KEPs associated with all enhancements landing in v1.14.0 must be merged with an implementable status. This 1.14-specific extension is intended to allow time to complete KEPs that were in progress by enhancements freeze. In future releases, the intent is to require associated KEPs be merged/implementable by the enhancements freeze date.

We will de-milestone any enhancements that fail to meet these criteria. Any new enhancements not in the milestone will require an Exception. We will be lenient within reason if a KEP not quite landing on time is the justification.

SIG "themes" should also be in the release notes draft at this time to prepare for blog posts and release marketing. Any work the SIG wants publicized needs to be called out to the Enhancements Lead so the Release Team communications lead can work with SIG-PM and the CNCF.


One week prior to Code Freeze, we increase the cadence of release team meetings to begin tracking work more closely. We call this Burndown, because at this point we have a list of outstanding issues and PRs, and are actively working to burn that list down. SIG representatives are asked to attend if their SIG has specific outstanding issues that are blocking the release.

Join kubernetes-sig-release@ to get a calendar invite. This meeting may conflict with other community meetings. Please prioritize this meeting if a member of the release team asks you to attend.

The intent of these meetings is to:

  • Focus on fixing bugs, eliminating test flakes and general release stabilization.
  • Ensure docs and release notes are written and accurate.
  • Identify all enhancement going into the release, and make sure alpha, beta, GA is marked in enhancements repo.
  • Provide a one-stop view of release progress including relevant release metrics.

Code Freeze

All enhancements going into the release must be code-complete, including tests, and have docs PRs open by Thursday, March 7th, 2018.

The docs PRs don't have to be ready to merge, but it should be clear what the topic will be and who is responsible for writing it. This person will become the primary contact for the documentation lead. It’s incredibly important that documentation work gets completed as quickly as possible.

After this point, only release-blocking issues and PRs will be allowed in the milestone.

Code Thaw

One week prior to release, it is expected that all but a handful of outstanding PRs for kubernetes v1.14.0 have landed in the release-1.14 branch. Assuming the release team agrees, Code Freeze will be lifted, and we enter Code Thaw.

From this point forward, any PRs intended for v1.14 must be cherry picked to the release-1.14 branch.



Starting at Enhancements Freeze the release team will solicit and rule on exception requests for enhancements and test work that is unlikely to be done by Code Freeze. The exception approval is the responsibility of the SIG or SIGs labeled in the pull request. The release team may intervene or deny the request only if it poses a risk to release quality, or could negatively impact the overall timeline. Changes introduced at this point should be well-tested, well-understood, limited in architectural scope, and low risk. All of those factors should be considered in the approval process. Enhancements on an feature branch with documentation, test cases, and passing CI are more likely to be accepted.


Enhancements that are partially implemented and/or lack sufficient tests may be considered for pruning beginning after Code Freeze, unless they've been granted an Exception.

The release team will work with SIGs and enhancements owners to evaluate each case, but for example, pruning could include actions such as:

  • Disabling the use of a new API or field
  • Switching the default value of a flag or field
  • Moving a new API or field behind an Alpha Enhancements gate
  • Reverting commits or deleting code

This should occur before 1.14.0-beta.1 is cut so we have time to gather signal on whether the system is stable in this state. These are considered drastic measures, so the release team will strive to coordinate at-risk work with SIGs before this time. The goal is to make code freeze, and overall project transparency, enforceable despite the lack of a consistently used feature branch process.


If an enhancement needs documentation, enter "Yes" in the enhancement tracking spreadsheet and add a link to the documentation PR. You can open documentation PRs in the kubernetes/website repository. If you have questions, the release documentation lead, or representatives from SIG-Docs will be happy to assist you.

For documentation PRs:

  • Open PRs against the dev-1.14 branch based off of the 1.14 release PR. The documentation workflow uses feature branches for release documentation, rather than basing from master. Be sure to open your PR against the release branch.
  • Add your PR to the 1.14 Release milestone.
You can’t perform that action at this time.
