    Interface and balance

    • Widespread class tuning and the first pass of Naxxramas fixes.
    • Adds equipment manager and interface improvements.

    Secrets of Ulduar

    Major release
    • Ulduar opens with optional hard modes triggered inside the encounters themselves.
    • Dual talent specialization arrives, letting characters carry two full talent builds.

    Call of the Crusade

    • Trial of the Crusader opens with four separate lockouts across two difficulties.
    • Isle of Conquest joins the battleground rotation.

    Fall of the Lich King

    Fan favorite
    • Icecrown Citadel opens on a staged wing-by-wing schedule with a stacking buff.
    • The Dungeon Finder arrives, matchmaking players across realms automatically.
    • Adds the Frostwing Halls encounters and the expansion's closing raid.
    What this means for a buildCross-realm matchmaking is the single largest subsystem in the branch. The ICC script is the most re-implemented in emulation.

    Ruby Sanctum

    Build targetMajor release
    • Ruby Sanctum opens as a short final raid behind the Obsidian Sanctum.
