A new trailer, and a game a third the size
The second trailer is up on the Videos page: from the old ballad to the Rootherd, filmed in the game this week.
The game is also much lighter. It now takes 1.9 GB on your drive instead of 5.8 GB, and the launcher fetches only what changed, so most updates are a few megabytes. If you already play, just start the launcher as usual; it brings the new version in by itself.
The rest of this update (raids on Brightwater, the quest log on L, the old ballad, weapons held properly) is in the patch notes.
