Version 0.15 is now available in beta mode. To access it, go to your Steam Library and right click Wolfpack. Select Properties, and then Betas. Select Beta. Wait for the download and start playing. Version 0.15 will be moved to the default branch in a few days.
The old and new verisons are not backwards compatible, so you won't be able to see servers hosting another version of the game.
