The privacy work started here. The system photo picker let a user share
chosen photos and videos without the app holding a storage permission, and
Google planned to bring it to Android 11 and later through a MediaProvider
module update. NEARBY_WIFI_DEVICES, in the NEARBY_DEVICES group, let
Wi-Fi apps scan and connect without location when they declare
neverForLocation.
For developers the build added the Quick Settings tile placement API, themed
app icons (on Pixel at first), a platform API for per-app languages, faster
hyphenation through the fullFast and normalFast frequencies,
RuntimeShader with AGSL, and the first OpenJDK 11 core library updates.
Bluetooth and Ultra-wideband became new Mainline modules. Most behaviour
changes could be toggled one by one from Developer options or adb.
