@thockin @alexanderConstantinescu can one of you confirm that this targeting beta for v1.27.
Thanks!

[alexanderConstantinescu]

Yes, that is correct and what we've discussed / agreed on the KEP. Maybe @thockin wants to give the final confirmation?

[thockin]

yes please - this one doesn't have APi so doesn't need an alpha

[marosset]

Thanks @thockin @alexanderConstantinescu

Hello @alexanderConstantinescu 👋, Enhancements team here.

Just checking in as we approach enhancements freeze on 01:00 UTC Friday, 16th June 2023.

This enhancement is targeting for stage stable for 1.28 (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: 1.28
• KEP readme has a updated detailed test plan section filled out
• KEP readme has up to date graduation criteria
• KEP has a production readiness review that has been completed and merged into k/enhancements.

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

• The kep.yaml file is a bit confusing for me, is this enhancement targeting1.28 for the stage stable or beta?

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

[thockin]

@alexanderConstantinescu https://github.com/kubernetes/enhancements/blob/master/keps/sig-network/3458-remove-transient-node-predicates-from-service-controller/kep.yaml still says "beta" and needs final PRR signoff (thanks, @wojtek-t for the poke)

[alexanderConstantinescu]

Are we on-target for GA iin 1.28?

Sorry for the late reply to this: the KEP says GA in 1.29 that isn't advanced to 1.28 just because the release went well, right?

[alexanderConstantinescu]

@alexanderConstantinescu https://github.com/kubernetes/enhancements/blob/master/keps/sig-network/3458-remove-transient-node-predicates-from-service-controller/kep.yaml still says "beta" and needs final PRR signoff (thanks, @wojtek-t for the poke)

Thanks for the reminder! Here's the PR: #4088

I didn't update the stable milestone because of I mentioned above

[thockin]

Sorry, somehow I thought it was GA this release. Milestone bumped
