Hi @danwinship 👋, 1.29 Enhancements team here!

Just checking in as we approach enhancements freeze on 01:00 UTC, Friday, 6th October, 2023.

This enhancement is targeting for stage alpha for 1.29 (correct me, if otherwise).

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: 1.29. KEPs targeting stable will need to be marked as implemented after code PRs are merged and the feature gates are removed.
• 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).

It looks like #3824 will address most of these issues!

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!

[danwinship]

@npolshakova #3824 is merged now... is this close enough or do I need to file an exception?

[npolshakova]

@danwinship, yep since there was a verbal approval on #3824, you do not need to file an exception. Now that it's merged you are tracked for enhancement freeze 🚀 .
