Blizzard Entertainment deployed today a new patch for Diablo III: Rise of the Necromancer Beta. The Diablo III 2.6.0 (45634) Patch Notes are available. No new discernible new content other than a bug fix that allowed non-Necromancers to loot Necromancer loot.
In this patch, Rifts and Greater Rifts with the Temple of the Firstborn tileset will benefit from a new change that reduces the amount of dead ends.
