Git branch detection
Uploads and runs now follow your Git branch, so a build lands where your code lives.
This release also sets a new app’s default branch from its first upload, reuses matching native builds across branches for Expo and React Native apps with fingerprinting on, and opens Atlas on All branches when a link names no branch.
Git branch detection
Upload without picking a branch, and the build goes to your current Git branch. Automatic runs try that branch first, then fall back to your app’s default branch. Explicit branches, exact builds, and saved choices still win. Prefer the default branch? Turn off Automatic Git branch detection in App settings → Build branches.
