Re-animating the last source code wasn't as easy as planned due to some ugly crashes when compiling the client.dll in release mode.
Since We haven't found the bug yet, We've put up a version with the client.dll compiled in debug-mode. It'll be tested within the next days.
If everything works out fine and there are no critical lacks of performance, we'll be able to release beta 2.1 very soon.
Thanks for your patience and interest.
