Maintenance Checklist

  1. When a new Expo SDK patch or minor release ships, review sdk56-breaking-changes, expo-ui-native, and eas-update-ota.
  2. When EAS Observe becomes GA, update beta wording in performance-profiling.
  3. When the expo-widgets API reference alpha banner is removed, simplify the caveat.
  4. When the Expo Router migration guide changes, re-check codemod commands and import boundaries.
  5. When EAS CLI major versions change, update eas-build-pipeline and the Expo handbook check script together.
