[ANNOUNCEMENT] v1.35 Call for Enhancements
Rayan Das
Hello Kubernetes community!
The v1.35 release cycle has begun and we are now actively collecting enhancements.
Actions Required:
SIG Leads:
Discuss within your SIG which enhancements you will be proposing for this release
Opt in for enhancements by applying the current milestone (v1.35) and "lead-opted-in" label on the tracking issues in kubernetes/enhancements[1]
Enhancements owners:
Ensure your enhancements meet the PRR Freeze requirements[2]
Ensure your enhancements meet the Enhancements Freeze requirements[3]
Open an issue in kubernetes/enhancements[1]
Ensure that a kep.yaml exists with:
status[4] set to `implementable`
latest-milestone[5] set to the current release.
A README.md exists that:
uses the latest template[6]
has the updated test plan[7] section filled out
A Production Readiness Review[8] has been completed
Reviewers/Approvers:
Please add the “kind/deprecation” label to PRs as appropriate (this is a big help for the Comms team!)
Enhancements will be tracked throughout the release using the 1.35 Enhancements Tracking GitHub Project board[9]. More information on the enhancements process can be found on the kubernetes/enhancements[1] repository.
All enhancements should plan to opt-in well before the Production Readiness Review Freeze (Thursday. 9th October 2025) to ensure adequate time for reviews. Enhancements opted-in after this deadline will be at risk for inclusion in the release as Production Readiness Review Freeze deadline is a hard deadline. If you miss the deadline, you'll need a PRR exception
