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!

Does the description update look ok?

[AnaMMedina21]

@sethev Looks great! Will keep an eye out for #4493

[sethev]

@AnaMMedina21 status set to implementable!

This enhancement is targeting for stage for v1.30 (correct me, if otherwise)

Hey again @sethev 👋 Enhancements team here,

Just checking in as we approach code freeze at 02:00 UTC Wednesday 6th March 2024 .

Here's where this enhancement currently stands:

• All PRs to the Kubernetes repo that are related to your enhancement are linked in the above issue description (for tracking purposes).
• All PR/s are ready to be merged (they have approved and lgtm labels applied) by the code freeze deadline. This includes tests.

Also, please let me know if there are other PRs in k/k we should be tracking for this KEP.
As always, we are here to help if any questions come up. Thanks!

@AnaMMedina21 i should have a PR submitted tomorrow, but it looks like i've missed the code freeze for 1.30 :(

👋 Hello @sethev

‼️ This KEP needs documentation with a review complete by Doc Freeze on March 26th 18:00 PT (coming up quick!) to get this into the release. After that date, an exception needs to be filed and may risk this feature not getting released with 1.30.

The start of a review was due a week ago, and I see that the documentation is still a draft. Both SIG-Docs and a technical reviewer from SIG network needs to review documentation by that March 26th date.

As a user of Kubernetes, I really appreciate your contribution with good documentation to help me understand how to utilize your new enhancement. Thanks!

This PR was labeled tracked for code freeze by mistake. As it doesn't have any PR, I'm removing this from milestone.

/milestone clear

[thockin]

@sethev - are you going to be working on this in 1.31 ?

[thockin]

@sethev the clock for 1.31 is ticking - AFAICT there is not an open PR for this (though there was an older one pre-KEP) - are you still pursuing this?

[thockin]

@sethev - are you still around? If not, then this KEP is likely to get closed, unless someone else picks it up.
