The first major content patch of the expansion was Patch 3.1: Secrets of Ulduar released on April 14, 2009. Storm Peaks have been updated with Ulduar, a new raid where players had to confront Yogg-Saron. Death Knights were first introduced to the game and the level cap was increased to 80 in Wrath of the Lich King. Many consider it the best WoW expansion to date. On 13th November 2008, Blizzard released World of Warcraft's third expansion Wrath of the Lich King.
We've got a double celebration today! Wrath of the Lich King's 13 anniversary and Warlords of Draenor's 7th anniversary.
