Sorry for the delay. ProtocolLib is still not fully stable on 1.19 and I haven't yet been able to fix some bugs because of this. However, I don't want to keep you waiting any longer so I've released this update with experimental 1.19 support. Most features seem to work on 1.19, but there are some that I could not get to work: NightVisionEffect, HideAdvancements, SetSleepingIgnored (bed player count). I will re-enable those features on 1.19 as soon as ProtocolLib is more stable or I can find a workaround.
