We're building Expo Observe, a new way to understand how your app performs in the real world.

Today we're announcing the release of Expo SDK 55. SDK 55 includes React Native 0.83. Thank you to everyone who helped with beta testing.

EAS supports build caching, which can speed up subsequent builds by up to 30% on both Android and iOS builds. Build caching is available to all users at no additional cost, whether you're on a free or paid plan.

Workflows insights aggregates data from all of your workflow runs in the insights tab on the Expo dashboard. You can monitor key metrics like success rates, active runs, and failure counts, while observing trends over time to understand how your workflows are performing.

Here's what you need to know when it comes to if your Expo app is affected by recent security vulnerabilities in React Server Components and how to upgrade it to stay protected.

Organizations on Production and Enterprise plans can now require members to enable two-factor authentication (2FA). For organizations with SSO enabled, this requirement only applies to non-SSO users.

We're deprecating the GitHub build triggers feature to focus our efforts on delivering the best mobile CI/CD experience through EAS Workflows.

Scheduling workflows allows you to automate routine tasks like building and submitting your app on a regular cadence. This eliminates the need to manually trigger builds and submissions, so that you can do things like have your biweekly production builds already submitted to the app stores by the time you arrive at work.

The TestFlight job allows you to distribute iOS builds directly to TestFlight internal and external testing groups. Unlike the standard iOS submit job, the TestFlight job provides advanced control over TestFlight features including test group management, changelog distribution, and Beta App Review submission.

The GitHub comment job posts reports of your workflow's completed builds and updates to GitHub pull requests. It makes it easy for your reviewers and testers to see what your changes will look like once they're deployed.

Today we're announcing the release of Expo SDK 54. SDK 54 includes React Native 0.81. Thank you to everyone who helped with beta testing.

We've added support for Xcode 26 beta on our macOS build infrastructure, allowing you to build and test your apps with the latest iOS 26 features before the public release later this fall.

React Native 0.80 is supported in a canary release of the Expo SDK, instructions available in this post. Expo SDK 54 will be released in late summer and will likely support React Native 0.81.
