Code Freeze Exception Request: KEP-5598 Opportunistic Batching

[Roman Baron]

Hello Release Team,

I'd like to request a 7 calendar day code freeze exception for the following enhancement.

Enhancement name: Opportunistic Batching (KEP-5598)

Enhancement status: Beta (v1.37)

SIG: SIG Scheduling

k/enhancements issue: kubernetes/enhancements#5598

Tracking issue: kubernetes/kubernetes#137707

PR #s: 

https://github.com/kubernetes/kubernetes/pull/138788 (merged)
https://github.com/kubernetes/kubernetes/pull/138849 (merged)

https://github.com/kubernetes/kubernetes/pull/140289 (pending)

Additional time needed: 7 calendar days (due Wednesday, July 29 AoE)

Reason this enhancement is critical for this milestone:

This PR is the final implementation PR for the current Beta scope of the Opportunistic Batching enhancement targeted for v1.37. The preceding implementation PRs have already merged: 

https://github.com/kubernetes/kubernetes/pull/138788
https://github.com/kubernetes/kubernetes/pull/138849 

This PR completes the remaining implementation work for the current Beta scope and resolves the associated tracking issue. Without it, the enhancement would not be fully implemented in v1.37.

Reason the extension is needed:

The implementation is complete and the PR is currently under active review by SIG Scheduling maintainers. Since some of the reviewers are on planned vacation during the code freeze period, I'm requesting 7 calendar days to allow sufficient time for the review process, address any feedback, and get the PR merged.

Risks from adding code late:

The scope of this PR is limited to completing the existing implementation. It builds on functionality that has already been reviewed and merged, and I expect any remaining changes to be driven primarily by review feedback.

Risks from cutting the enhancement:

If this PR does not make the v1.37 release, the current Beta implementation of Opportunistic Batching would remain incomplete and the remaining work would need to be carried over to a future release.

Thank you for your consideration,

Roman Baron

Hi all,

After reviewing the request and the discussion in the referenced Slack thread [0], the Release Team is APPROVING this exception request for a 5 calendar day extension rather than the originally requested 7 days.

Based on the 5 calendar day extension, the updated deadline for this KEP is: Monday, 27th July 2026 (Anywhere on Earth) / Tuesday, 28th July 2026, 12:00 UTC.

Please note that all remaining reviews and pending work needs to be completed within this extension. Otherwise, this will need to be deferred to a future release.

If you need any clarification, please feel free to reach out to us in the #sig-release Slack channel.

Thanks,
Dipesh Rawat
