Do you have a link for info on that? I tried the changelog https://lineageos.org/Changelog-28/

edit, found this - only for for microG Companion/Services https://review.lineageos.org/c/LineageOS/android_frameworks_...

Official builds before this could still be made to work with microg using the "microg installer revived" Magisk module. That's how I installed it on my current phone while still getting the benefits of more regular updates.
