The Armory has been updated to reflect the new dual spec feature given to us by patch 3.1. It now shows both talent specs for characters that have bought dual spec, and shows equipped glyphs on the talent view.
There's also been a bit of a facelift overall, with new buttons for the various sections of a character's profile, and some achievement statistics shown on the main profile page. The "Last Updated" date is a nice touch, although recently I find the Armory usually contains fairly fresh info [edit: apparently this is not a new feature].
I was having some display problems, but it turns out that disabling Adblock Plus on Armory fixed it, so if anyone else is seeing elements display in the wrong places, try that. And yes, I am enjoying playing with Shadow, thanks. Quite a bit, actually.
