Google will begin releasing Android Open Source Project (AOSP) source code only twice a year starting in 2026. "In the past, Google would release the source code for every quarterly Android release, of which there are four each year," notes Android Authority. From the report: Google told Android Authority that, effective 2026, Google will publish new source code to AOSP in Q2 and Q4. The reason is to ensure platform stability for the Android ecosystem and better align with Android's trunk-stable development model.
Developers navigating to source.android.com today will see a banner confirming the change that reads as follows: "Effective in 2026, to align with our trunk-stable development model and ensure platform stability for the ecosystem, we will publish source code to AOSP in Q2 and Q4. For building and contributing to AOSP, we recommend utilizing android-latest-release instead of aosp-main. The aosp-latest-release manifest branch will always reference the most recent release pushed to AOSP. For more information, see Changes to AOSP."
A spokesperson for Google offered some additional context on this decision, stating that it helps simplify development, eliminates the complexity of managing multiple code branches, and allows them to deliver more stable and secure code to Android platform developers. The spokesperson also reiterated that Google's commitment to AOSP is unchanged and that this new release schedule helps the company build a more robust and secure foundation for the Android ecosystem. Finally, Google told us that its process for security patch releases will not change and that the company will keep publishing security patches each month on a dedicated security-only branch for relevant OS releases just as it does today.
