Start with validation. PR 140572 migrates the Condition Type field to a declarative format check, ensuring it matches proper label-key syntax, and marks the old handwritten check as superseded. PR 141677 does the same for CronJob schedule validation, graduating it from beta to stable and removing redundant legacy…

That fix is now cherry-picked into releases 1.35, 1.36, and 1.37, PRs 141666 through 141668. This is a good reminder…
Third, general maintenance: Liggitt's PR 141663 bumps the toolchain to Go 1.27, catching a real error-wrapping bug along the way, while PR 141658 updates the containerd API and trims unwanted dependencies. There's also a dry-run structured-merge-diff bump, PR 141664, currently on hold,…
