The app released on the App Store and Play Store is always the one on the production branch. We use EAS Update to remotely update the app when necessary. In general, this means that the semver patch version is bumped.

For major updates that don't work via EAS Update (such as an Expo SDK version bump), a new app binary is created using the commands below. In general, this means that the semver minor version is bumped.

eas build -p ios
eas submit -p ios

# Android
