We’ll be releasing an early October security update today since there hasn’t been an official Android Open Source Project and stock Pixel OS release yet. They’ll likely release it with Android 14 and we’ll be fully focused on quickly porting to Android 14 once it’s available.

Android 14 will likely be released on October 4th and Android 13 will no longer have monthly or quarterly stable releases. Android 13 will only have the monthly release of the Android Security Bulletin (ASB) patch backports to 11, 12, 13 and soon 14. Those aren’t all the patches.

The full set of patches is provided by the monthly, quarterly and yearly releases of Android. Their policy is for every Critical/High severity AOSP patch to be backported. Most Moderate/Low severity patches aren’t backported. However, severity levels are often very arbitrary.

Pixels will only be supported by Android 14 going forward so the many patches for firmware, drivers and other hardware-related code will only be available via Android 14. This is why GrapheneOS has focused so much on porting to Android 14 in order to quickly migrate over to it.
