Hello @haircommander 👋, v1.35 Docs Team here again!

We are closing in on the deadline to get your PR ready for review before Tuesday 18th November 2025, so I'm sending a second reminder. Please take a look at the Documenting for a release - PR Ready for Review document to get your PR ready for review before the deadline.

Please also let us know once your PR is fully Ready for Review -- meaning all documentation updates are complete and it's awaiting reviewer feedback -- so we can update our tracking.

Thank you!

@haircommander The PR is currently lacking the change to transition the feature gate ImageMaximumGCAge from Beta to Stable. The necessary change should be made in the feature gate description file - ImageMaximumGCAge.md (here). Also, would also help if you include the upstream k/k implementation PR in the pull request description.

Please refer to the documentation here for further information.

 #### Garbage collection for unused container images {#image-maximum-age-gc}

-{{< feature-state feature_gate_name="ImageMaximumGCAge" >}}


We should leave the feature-state shortcode line in place.

it is GA. What would be the purpose of keeping it?

Historically we kept the shortcode for GA features.
I think usually aim to clean it up in later releases after the feature gate is removed. It is fine to remove the shortcode now and it does not block the merge.

Keeping it in helps people see that they'd better upgrade their cluster (imagine if they are running K8s 1.29), and if they work anywhere that has a policy like "beta features in production need signoff", it helps them spot that need for a sign off.

We typically drop mentioning the feature gate when it has been removed from Kubernetes, or if it has not been removed but is locked to true for all supported versions.

I have a PR to let you leave the shortcode in, and automatically get that rendered as a more helpful text explanation once the feature gate is marked as removed. @dims has a draft PR to automate setting feature gate metadata, per feature gate, for each minor release.

Hello @haircommander 👋! I'm reaching out from the Docs team. Just checking in as we approach Docs Freeze on 3rd December 2025, 12:00 UTC.

This documentation appears to still be under review. To meet the Docs Freeze, this PR must have a technical review as well as lgtm and approve labels applied, without any unaddressed comments or concerns from SIG Docs. The status of this enhancement is marked as at risk for docs freeze. Thank you!
