Unfortunately the implementation PRs associated with this enhancement have not merged by code-freeze so this enhancement is getting removed from the release.

@alexanderConstantinescu https://github.com/kubernetes/enhancements/blob/master/keps/sig-network/3836-kube-proxy-improved-ingress-connectivity-reliability/kep.yaml still says Alpha and needs a PRR touch to move to beta

[alexanderConstantinescu]

Thanks for the reminder, sorry for being late. Here's the PR: #4087

[Atharva-Shinde]

Hey @alexanderConstantinescu

This is a nit that needs to be addressed:
Add the acknowledgement under the Test Plan section.

I won't decline this KEP for the Enhancements freeze because of this change but would be great to get a PR ready addressing them.
The status of this enhancement is marked as tracked. Please keep the issue description up-to-date with appropriate stages as well. Thank you :)

[alexanderConstantinescu]

@chanieljdan : sorry for the delay! It was indeed agreed that this enhancement should result in a document written in https://kubernetes.io/docs/concepts/. Here's a placeholder PR I created for this: kubernetes/website#45290

What is the deadline for the final docs PR to merge for 1.30?

@alexanderConstantinescu GA in 31?

[sreeram-venkitesh]

Hi @alexanderConstantinescu! v1.31 Enhancements lead here 👋🏼

I'm removing the lead-opted-in label for now. If you wish to progress this enhancement in v1.31, please have the SIG lead opt-in your enhancement by adding the lead-opted-in label and set the milestone to v1.31 before the Production Readiness Review Freeze. Please let me know if you have any questions.

/remove-label lead-opted-in

[aojea]

@alexanderConstantinescu @thockin this is just removing the flag during this release, isn't it?

we should opt in then

[thockin]

No, this one is Beta->GA

[aojea]

No, this one is Beta->GA

oh, wanted to mean that there is no much work and we should opt-in

[thockin]

Agree, I just want @alexanderConstantinescu to ACK

[alexanderConstantinescu]

Yes, 1.31 is Beta -> Stable and to the best of my knowledge the graduation criteria defined on the KEP are already satisfied, so it's a matter of "filling out the paperwork" (updating the KEP/feature gates)

[thockin]

ACK!

Hello @thockin 👋, Enhancements team here.

Just checking in as we approach enhancements freeze on 02:00 UTC Friday 14th June 2024 / 19:00 PDT Thursday 13th June 2024.

This enhancement is targeting stage stable for v1.31 (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: v1.31. 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). 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 so that the PRR team has enough time to review your KEP before the enhancements freeze.

For this KEP, it would be good to update the following:

• Implementation history in the KEP README

Other than this, all the KEP requirements are in place and merged into k/enhancements, this enhancement is all good for the upcoming enhancements freeze. 🚀

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

Howdy @thockin, @alexanderConstantinescu, SIG Docs co-chair here 👋 I wanted to add another reminder about the docs deadline for this enhancement: updating feature gates qualifies as requiring documentation as far as Release Docs is concerned, so please check out @Princesso's reminder above to ensure you meet the deadline today

[aojea]

@natalisucks I've opened the PR on behalf of @alexanderConstantinescu kubernetes/website#47030
not blog docs

[alexanderConstantinescu]

Hi! Sorry for the confusion, I was away on vacation for the past two weeks. I've filed: kubernetes/website#47048 which will supersede @aojea's PR.
