The SDK 55 beta is now available for developers to test for about two weeks. It includes major updates like support for Hermes v1, a revamped project template, and expanded AI tooling, along with dropping support for the Legacy Architecture. Developers can check changelogs and participate in Discord office hours for testing.

Expo SDK 53 beta has been released for a two-week testing period, featuring React Native 0.79.0 and React 19.0.0, with significant changes such as the New Architecture being enabled by default for all projects and improved support for edge-to-edge display in Android apps. Developers are encouraged to test the new features and provide feedback during this beta phase.
