LineageOS 17.1, based on Android 10, released
We have been working extremely hard since Android 10's release last August to port our features to this new version of Android. Thanks to massive refactoring done in some parts of AOSP, we had to work harder than anticipated to bring some features forward, and in some cases, introduced implementations similar to some of our features into AOSP (but we'll get to that later).
Other than the Android 10 features, LineageOS 17.1 also brings back theming support (deprecated in 13.0), and the default installation solution is now Lineage Recovery (but other recoveries are still supported, and may even be advised by maintainers for specific devices).
Not every Android devices is supported right away, of course, but there's a decent number of supported devices regardless.
