It means they rebased all their changes on top of the new version. This is usually time-consuming because AOSP is not developed in the open, so you can't do this incrementally as things change -- you just get a massive drop sometime after release.

Android makes yearly releases. It is developed in cathedral-style. Google releases the source as a single big update. GrapheneOS is a fork. They need to port their customizations and extra software on top of the new release.

Every six months, not yearly. Google releases the major version and QPR2 as part of AOSP. QPR1 and QPR3 are Pixel-only.

Since they switched to QPRs and Pixel drops, major releases have become less important because feature roll out throughout the year. It's just that nobody outside GrapheneOS and Samsung (to my knowledge) rolls out QPR2, so for non-Pixel/Samsung, the major releases are... major.

I think another major source of work for GrapheneOS is when Google releases QPR1 and QPR3, because GrapheneOS had to rebase the driver/firmware changes on top of QPR0/QPR2.

It's a fork of the Android Open Source Project (AOSP) with major privacy/security improvements and alternatives to Google apps/services. The massive set of changes needs to be ported to new major versions of AOSP.

The apps also need to be updated to the Android 17 target API level but that can happen over several months following the OS itself being ported to it. The app aspect is something all Android developers need to deal with due to new target API levels bringing backwards incompatible improvements.

Think of GrapheneOS as being a set of patches on top of the Android Open Source Project that Google releases:

They've ported the patches to work on top of the latest release.

Well, both, probably. GrapheneOS requires a lot of framework and device side changes.
