# Expo SDK 58 beta: test iOS 27 scenes and agent CLI before leaving 57

Expo published the [SDK 58 beta](https://expo.dev/changelog/sdk-58-beta) on 15 September 2026. The beta runs three to four weeks — enough to learn whether iOS 27 scene lifecycle, React Native 0.88 RC, fingerprint defaults, and the new agent-facing CLI break *your* AppDelegate customizations, config plugins, and agent runbooks.

Do not treat `@next` as a silent production pin. Keep one branch, one checklist, one owner, and a hard rule that coding agents may not bump production to SDK 58 beta without that gate passing.
