The next update "Wrathstone" will be on the PTS today.
New API Version: 100026
PTS Dev Guild
We always try to create a guild for all addon developers during the PTS cycle for a new update, 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, but keep in mind that it gets wiped with every character copy and may not currently exist.
The PTS will experience weekly character copies this time, so we decided to create a guild on both NA and EU server which you can join more permanently.
