Let me begin with a big thanks to @chrmhoffmann!
So, we now have official LoS 16 since 2019-05-13, the current version is lineage-16.0-20190514-nightly-FP2-signed.zip (releases can be found here: https://download.lineageos.org/FP2).
What are your observations, upgrade stories, bugs and all that?
My observations are that an upgrade from LoS 15.1 was easy! I formatted /system, installed the Zip via TWRP (a decrypt of /data was neither possible, nor needed) and it works. The ONLY thing I needed to re-do were the homescreen customizations.
One thing that came directly to my attention is that swiping through the homescreens is a little sluggish and laggy. I’ve been using the efficient battery setting and now changed to balanced - well doesn’t make a great difference.
The WLAN-bug (constant disconnects) is still there for me, so nothing better on that side.
@chrmhoffmann Is H.264 video acceleration working in LoS 16 yet? AFAIK Fairphone was able to provide a fix via a recent Android 7 beta update: https://bugtracker.fairphone.com/project/fairphone-android-7/issue/28.
