EAS Build is used by thousands of developers to build their apps on a daily basis. Some of these developers experience friction when they try to build a project via EAS Build, only for it to fail quickly for a variety of reasons, such as invalid configurations or minor code errors. This can be a frustrating experience, and doubly so when these failed builds cost developers money.

In an effort to continuously improve the Expo developer experience, we're happy to announce that from May 1, 2024, these builds will no longer be billed for or count against your monthly quota if you are on a Free plan. We define a "fast-failed build" as one that fails within 3 minutes. Each account will get a maximum of 10 of these waived each month.

The SDK 51 beta period begins today and will last approximately one week. The beta is an opportunity for developers to test out the SDK and ensure that the new release does not introduce any regressions for their particular systems and app configurations. We’re also hosting office hours for those of you interested in helping test the release!

SDK 51 beta includes React Native 0.74. The full release notes for SDK 51 won't be available until the stable release, but you can browse the changes in the expo/expo CHANGELOG to learn more about the scope of the release and any breaking changes.

Starting on April 29th, 2024, apps uploaded to App Store Connect must be built with Xcode 15 for iOS 17, iPadOS 17, tvOS 17, or watchOS 10. To ensure that your builds are compatible with the upcoming requirements, you can opt-in to use the Xcode 15 for your iOS builds by specifying "image": "macos-sonoma-14.4-xcode-15.3" or "image": "latest" in your eas.json configuration file.

Following Apple's announcement we are planning to drop the support for all of the iOS images with Xcode < 15 a month after the required Xcode version changes on Apple's side. This means that starting on May 29th, 2024, we will no longer provide the following images:

• macos-monterey-12.1-xcode-13.2
• macos-monterey-12.3-xcode-13.3
• macos-monterey-12.4-xcode-13.4
• macos-monterey-12.6-xcode-14.0
• macos-monterey-12.6-xcode-14.1
• macos-monterey-12.6-xcode-14.2
• macos-ventura-13.3-xcode-14.3
• macos-ventura-13.4-xcode-14.3.1

If you are using one of the images listed above, we recommend updating your configuration to use Xcode 15 as soon as possible to avoid any disruptions in your build process.
