Hi @danwinship! 1.23 Enhancements team here. Just checking in as we approach enhancements freeze at 11:59pm PST on Thursday 09/09. Here's where this enhancement currently stands:

• Updated KEP file using the latest template has been merged into the k/enhancements repo.
• KEP status is marked as implementable
• KEP has a test plan section filled out.
• KEP has up to date graduation criteria.
• KEP has a production readiness review that has been completed and merged into k/enhancements.

For this one, looks like we'll need the kep.yaml updated to reflect the current stage and latest milestone. It also looks like you'll still need to complete a PRR.

Thanks!

@salaxander sorry, the initial description hadn't been updated in a while. This did not go alpha in 1.22 and thus is not scheduled to go beta in 1.23 (but should hopefully be alpha, and I think we are good there, because you don't need a completed PRR to go to alpha)

[salaxander]

@danwinship sounds good! Then we're all good once the KEP updated merges

If you want to hit 1.23 you need a PRR soon. Should be pretty simple.

Hi, 1.23 Enhancements Lead here 👋. With enhancements freeze now in effect, this enhancement has not met the criteria for the freeze and has been removed from the milestone.

As a reminder, the criteria for enhancements freeze is:

• KEP is merged into k/enhancements repo with up to date latest milestone and stage.
• KEP status is marked as implementable.
• KEP has a test plan section filled out.
• KEP has up to date graduation criteria.
• KEP has a production readiness review for the correct stage that has been completed and merged into k/enhancements.

Feel free to file an exception to add this back to the release. If you plan to do so, please file this as early as possible.

Thanks!
