We've just got word from Blizzard of the first major update for Diablo III: Ultimate Evil Edition, and the new features that landed therein. Here's the details, direct from the demon's mouth:
The Vault
Whenever Treasure Goblins are defeated, there's now a chance they will spawn a new type of portal through which players can enter.
Legendary Gems
Legendary Gems are a new type of gem that can drop in Greater Rifts and The Vault and will offer powerful abilities when socketed into Rings and Amulets.
Greater Rifts
Greater Rifts are a special type of timed Nephalem Rift. Upon completing a Greater Rift, players will be able to choose between one of two rewards: a chance to upgrade their Legendary Gems or (if they complete the Greater Rift level within its allotted time) the opportunity to move on to the next Greater Rift level.
Ramaladni's Gift
Ramalandni's Gift is a new Legendary item that will allow players to add a socket to any weapon that does not already have one.
The Cesspools
When adventuring in Nephalem Rifts and Greater Rifts, players will have a chance to encounter a new randomised environment: The Cesspools.
