This is the first release of GrapheneOS based on Android 14 QPR2. Android 14 QPR2 is the first Android release following the new development model where quarterly releases follow the development branch. This release is a massive overhaul of the OS almost as large as the migration from Android 13 QPR3 to Android 14 despite fewer user facing changes. This release includes a large part of the migration to Android 15. The new development model will be very beneficial for GrapheneOS by spreading out the porting process throughout the year between major releases as part of the 3 quarterly releases between the yearly major releases.

Since this is a major release, the Pixel 4a (5G) and Pixel 5 have not been ported to Android 14 QPR2 as part our initial release. We need to determine whether it makes sense to move these end-of-life devices to Android 14 QPR2 or keep them on a legacy extended support release branch based on the last Android 14 QPR1 release.
