This page lists monthly site changes and documentation updates.
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,
android15-qpr2-release. See About android-latest-release
for more information.
Dark theme
Dark theme is available on source.android.com. Select light theme, dark theme, or device default from the controls in the header.
