With today's maintenance, Blizzard released patch 3.1.1, right on the heels of patch 3.1. The patch is a minor one, including many fixes to bugs that have escaped Blizzard on the PTR.

3.1.1 will come with a talent reset for everyone, since one of the bug fix is aimed at the new dual spec system. This won't remove your glyphs, but you have to be careful when re-talenting to make sure you match the proper talent pane with the proper glyph. Just a friendly heads up.
