Update - Almost forgot to mention that the Talent Calculator is now updated with the latest build from the Patch 3.0.8 PTRs. Glyphs will be updated shortly as well.
PTR 3.0.8 - Build 9464
The test realms have been updated to a new build. It doesn't look like there is a lot of changes here but some of them are really interesting.
New installer and launcher interfaces
The patch installer and launcher have been updated with a new interface.
Undocumented Changes
Undocumented changes are merely comparison of tooltips between the new version and the previous one. Changes made to spells aren't always reflected in tooltips and vice versa. Keep in mind that it's a test server and things might changes before it hits the live servers.
