Currently the last release of Arc is one year old. The fork (Anarki) has had more visible development, although it has slowed down after october 2008. You can see the full history here: http://github.com/nex3/arc/commits/master/ http://github.com/nex3/arc/commits/master/ . There has been no cross pollination of code: the anarki fork fixes a few bugs that are still present in the official release of arc and it has a few interesting extra features, such as the possibility of defining your own functions to be called when a non-function object gets called. Another interesting implementaton of arc, which does include a few features from anarki, is rainbow: http://github.com/conanite/rainbow http://github.com/conanite/rainbow .
