Hi @adrianmoisey 👋, v1.34 Enhancements team here.

This is a reminder of the upcoming PRR Freeze on Thursday 12th June 2025.

By this date, there must be a PR open in k/enhancements with:

• The KEP's PRR questionnaire filled out.
• The kep.yaml updated with the stage, latest-milestone, and milestone struct filled out.
• A PRR approval file with the PRR approver listed for the stage the KEP is targeting.

Having the PRR questionnaire filled out by this deadline will help ensure that the PRR team has enough time to review your KEP before Enhancements Freeze on Friday 20th June 2025. For more information on the PRR process, see here.
