The current version is 0.1b, which is the first public release in kind of minimum-viable-product form. We hope to have this project in active development so if you are Git-savvy, you may want to follow the repository on Bitbucket (below) for more frequent updates. But if you're not so into that, check back here for future semi-major releases.
Download a copy of version 0.1b here.
If you know how to use Git, or just want to suggest issues and such via the Bitbucket interface, go here. Note that we may relocate the ownership of the project to a more team-based Bitbucket account at some near-ish future point, so don't bookmark that URL -- it is subject to change.
