@NNN @archigato That's not how Android updates work. There was previously 1 major yearly release which was changed in 4 major quarterly releases and has been reduced down to 2 major releases per year. Those are made available to OEMs and published to the Android Open Source Project. There are monthly security backports to the major releases from the past around 3 years which are also pushed to the Android Open Source Project. Pixel stock OS is separate from what OEMs use which is the AOSP code.
@NNN @archigato Pixel stock OS no longer has nearly as many changes in the monthly releases beyond the security patch backports. QPR1 and QPR3 will be smaller releases than previously and stock Pixel OS exclusive. These releases are only relevant to GrapheneOS for Pixel support. We don't need to deal with it for another device.
GrapheneOS has security preview patch access already which we didn't receive from Motorola but rather from another OEM not working on devices supporting GrapheneOS.
