Major update

A major update is what the developer of Guild Wars, ArenaNet, calls an update of the Guild Wars game series that adds new locations to the game. Major updates are downloaded automatically as they come out and for free at no hassle to the user.

A major update will usually introduce a few new explorable areas, towns and many quests to the latest chapter and rejuvenate interest in the game.

Major updates so far:
 * In Chapter One: The Sorrow's Furnace update on September 7th, 2005.

Major updates are different from chapters in that they are free and their content is simply added to existing content and world map. While both types of releases add more locations, items and quests, chapters can add new professions and skills.
