We'll be opening svn.pysoy.org to the public on Friday afternoon (June 29th) by 5pm UTC, just after the release of GPLv3. The code should not be considered usable in this state, it may not even compile depending on recent commits, and no support is offered for it as we're extremely busy getting ready for Beta-1 release.
The engine's Beta-1 will be released Sunday at earliest (July 1st) and possibly as late as Monday July 9th. At that time the ticket system will be re-opened to users and support offered. Betas should not be used to build anything "real", as API changes are still pending and several critical features are missing, but is useful for learning and helping us track down the bugs in our current code.
