Developer Action Items
- β Diff the official changelog for GitHub before you bump β APIs, defaults, and removed flags only.
- β Install through the vendor's documented channel in staging; keep a one-command rollback and time-box the canary.
- β Grep your repo for old flag names, lockfile pins, and plugin versions that the notes mark as breaking.
- β Prefer the first patch cut over the day-zero tag unless you have a reason to be on the leading edge.
- β If GitHub Changelog did not name a region, plan, or SKU, screenshot the official availability line before you promise it to users.
