Some of the changes include eliminating dyes from lootboxes, a nerf to Minstrel codas, many tweaks to the Tower of Orthanc raid, the option to timestamp chat messages, and small improvements to the treasure hunt. The devs have also posted an updated list of known issues for the game.
As always, it's worth going through the patch notes to try to find the funny asides. In this update? "Addressed a number of typos. Probably added some new ones."
