Hello @klueska 👋, v1.32 Enhancements team here.

Just checking in as we approach enhancements freeze on 02:00 UTC Friday 11th October 2024 / 19:00 PDT Thursday 10th October 2024.

This enhancement is targeting for stage alpha for v1.32 (correct me, if otherwise)

/stage alpha

Here's where this enhancement currently stands:

• KEP readme using the latest template has been merged into the k/enhancements repo.
• KEP status is marked as implementable for latest-milestone: v1.32.
• KEP readme has up-to-date graduation criteria
• KEP has a production readiness review that has been completed and merged into k/enhancements. (For more information on the PRR process, check here). If your production readiness review is not completed yet, please make sure to fill the production readiness questionnaire in your KEP by the PRR Freeze deadline on Thursday 3rd October 2024 so that the PRR team has enough time to review your KEP.

For this KEP, we would need to update the following:

• Create the KEP readme using the latest template and merge it in the k/enhancements repo.
• Ensure that the KEP has undergone a production readiness review and has been merged into k/enhancements.

The status of this enhancement is marked as at risk for enhancement freeze. Please keep the issue description up-to-date with appropriate stages as well. Thank you!

If you anticipate missing enhancements freeze, you can file an exception request in advance. Thank you!

Hello @klueska 👋 v1.32 Enhancements team here,

Unfortunately, the implementation (code related) PR(s) associated with this enhancement is not in the merge-ready state by code-freeze and hence this enhancement is now removed from the v1.32 milestone.

If you still wish to progress this enhancement in v1.32, please file an exception request as soon as possible, within three days. If you have any questions, you can reach out in the #release-enhancements channel on Slack and we'll be happy to help. Thanks!
