Changes to AOSP
Starting March 27, 2025, the latest release branch will always be referenced by
the new android-latest-release manifest, which can be used directly with
Repo. We recommend platform developers use android-latest-release
instead of aosp-main to build and contribute to AOSP. The
android-latest-release manifest is set to the latest AOSP release branch,
android16-qpr2-release. See About android-latest-release
for more information.
