We have announced that our next event called The Court of Strahd begins on October 14th, and you can read more about that here. October 14th will be the release date for Update 82, but we are additionally adding an Update 81.4 for October 7th which will include Night Revels and the balance pass work being previewed on Lamannia. So, while the Lamannia preview is inclusive of both Update 81.4 and - some - parts of Update 82, the class balance work will be released prior to the formal release of Update 82.
