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.
