Starcraft2 resumed testing

On July 7th, Blizzard announced the start of the second beta phase of Starcraft 2. But personally, I was able to launch a beta just now - I hadn’t allowed it before. As I understand testing will last until July 27.
All achievements and ratings have been reset. Avatars and fonts are also new.
Before launching, the client will download an update of about 700 mb in size.
