Hello @sethev 👋, Enhancements team here.

Just checking in as we approach enhancements freeze on 02:00 UTC Friday 9th February 2024.

This enhancement is targeting for stage <insert-stage-here> for v1.30 (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: v1.30. 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).

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

• Please update kep.yaml, KEP status needs to be marked as implementable
• Can you also update your issue description to link to the KEP? https://github.com/kubernetes/enhancements/tree/master/keps/sig-network/4427-relaxed-dns-search-validation

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!
