Blizzard finally got around to adding the achievement and statistics information from in game to the armory, and I’ll be the first to say it was worth the wait! Anything you can find under the achievement interface in game can now be found in your characters armory profile plus there is an option to compare yourself with others! On top of all the cool new features, the newly WotLK inspired redesign also has a news feed on the front page showing all of the server and world firsts! Here is a look at some of the changes:

• To navigate between categories, simply click on the category or subcategory name on the left-side menu.
• The ability to compare achievements and statistics between multiple characters is expanded to allow you to compare up to four characters, even across realms.
• To compare multiple characters, simply click the tab labeled “Add Character to Compare” at the top right of the Achievements or Statistics interface. Enter the name and realm of the character you wish to compare to the one you are currently viewing. The second character’s portrait and achievements will appear next to the original one. You can add multiple characters in this manner, and can compare up to four characters at one time.
• The main Armory page now has a new, more streamlined look. A news feed displays recent Armory news as well as region-first achievements. After logging in, the news feed also displays realm-first achievements on the main character’s realm.
• Armory logins now persist for two weeks before expiring, and closing the Armory window no longer logs out of the Armory.
• New drop-down menus under the main search field direct you to common search categories, such as for Arena rewards from a particular season, items from tradeskills such as gems and glyphs, and so on.

You can keeo track of the changes via their update page.
