Probably we will do it at some point soon.

The reason now for not doing so is that not all of our team members have reliable internet connection and the source code is merged manually.

We are working hard on a totally new release with a lot of source code reorganization and features like integration with .NET framework, the long-awaited linux port and other stuff. We were always targeting at the widest possible audience so we are trying to maintain the all-in-one distributive for people who do want just to watch some features and try to tweak just some settings.

For the past two years we were preparing PhD theses, so there were not much time devoted to the engine, but right now we're back. We're thinking about public repository and trying to choose: Mercurial, CVS, SVN or  Git.

But still we cannot guarantee, that there will be regular updates in that repository.

Another sources patch will be probably useless (unless you just want to copy-n-paste from it  ) without the new data, so a complete update is comming soon. When? As soon as it is ready.
