Starcraft2 resumed testing

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