The next version just hit the PTS, so here is an update thread for that.
New API Version: 100023
PTS Dev Guild
We always create a guild for all addon developers on the PTS, so we can test guild related things and more, ask for help with testing or just chat.
If you need an invite, ask here or over on our
Gitter channel.

I'll edit the OP with more useful information as you post it.
