On Tuesday Blizzard released the preliminary patch notes for patch 2.4.2 via their official website. Among the many features included in the extensive notes, the standout was the fact that Torment difficulty will continue from XI to XIII. Other things changed in the patch include Adventure Mode, the UI, and some character classes. There are a lot of things planned, then, but all are subject to change.
A release date for when it will hit the Public Test Realm is still not available.
