Version 6.11:

Sihai Longwang now spawns the correct amount of bosses, including high-level variants that went unused.
It is now easier to reach Surtr's loot orbs in the lava, although it still isn't perfect. It doesn't get any better than this.
The item set called "The Shade" has been improved significantly. Looks so cool!
Projectiles from Bow of the Shades, Staff of the Shades and Staff of the Cosmos now pierce through enemies. This is a hidden effect that isn't displayed on the item tooltip.

Version 6.10:

Fixed a vanilla bug preventing Fafnir from spawning one of his copies.
Fixed the Colossal Scorpion not spawning for the quest "A Venom Most Foul". Due to how his spawn pool works and the fact that he drops a loot orb, the amount of boss spawns will vary and now includes champions.
Replaced the Spellbreaker ability on all Gilded Warlocks in Act 3 with the monster spell "Negative Energy Ray".
Changed the scaling on Energy Shield's "Reflection" to be more in line with the original version, and it no longer adds stun retaliation.

Version 6.9:

Added changes from EE Update #6 from the public beta. Please update your game version with the public beta.
Updated to the latest version of Awesome Artifacts.
Nightshade and Toxin Distillation for Envenom Weapon now also increase Instant Poison Damage.

Version 6.8:

Added changes from TQ:EE Update #5 from the public beta. Please update your game version with the public beta.
The loot chest for the Egypt dungeon now drops additional loot depending on your boss multiplier to make it compete with the additional loot orbs you get from killing multiple bosses in the other dungeons.

Version 6.7:

Restored Loot Plus drop rates for end of act bosses, which now drop chaos keys that are used to unlock dungeons in the public beta.
Dungeon bosses now spawn as many copies as intended.
Feiyi now spawns as many copies as intended.

Version 6.6:

Fixed an issue that caused mobs to award less Electrum than normal on the public beta.
Sihai Longwang now only spawns 1 boss, but is accompanied by champion dragonkin spawns. This prevents a bug where one copy of him would turn invisible and immortal and continue to attack you, and due to how his loot is spawned he would only ever drop 1 loot orb anyway no matter how many copies of him you killed.

Version 6.5:

Added changes from the latest public beta.

Version 6.4:

Nerfed the energy drain from one of the mummy priest auras even more. It was ridiculously overtuned after they changed it.

Version 6.3:

Increased the range of Taunt to 15 meters and the minimum amount of aggro generated.
Removed the damage reflection modifier for Tartarus from the pool of available modifiers.
Greatly nerfed the energy drain on one of the mummy priest auras.

Version 6.2:

Added support for Electrum.
