Hello @sunnylovestiramisu 👋, 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 alpha 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:

• Update status to implementable in kep.yaml
• Add the test plan in the readme file
• Address questions inside the Production Readiness Review Questionnaire

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!

Hi @sunnylovestiramisu , Could you update the link of Kubernetes Enhancement Proposal to https://github.com/kubernetes/enhancements/tree/master/keps/sig-storage/3751-volume-attributes-class.

The pr link is difficult for users to learn the content of this KEP.

Hi, enhancements lead here - I inadvertently added this to the 1.32 tracking board 😀. Please readd it if you wish to progress this enhancement in 1.32.

If you anticipate missing enhancements freeze, you can file an exception request in advance. Thank you!

I see that this issue has been opted-out of v1.33 and is now planned for a future release. I will go ahead and mark it as Deferred on the v1.33 board for tracking purposes - do let the enhancement team know otherwise.
