It’s nice to get LineageOS weekly updates automatically from within the OS, no need to download from an external site.
The update process is not as intuitive as it could be – reboots to TWRP, then I had to select ‘Install’ and find the update package at /data/lineageos_updates.
Don’t know what has changed (is there a changelog?). Noticed it has bumped up to October 5th patch level which is nice, caveats about what that actually means aside…
