I'd encourage you to try svn. If you are on Windows, just download http://tortoisesvn.tigris.org/
Alternatively, svn can be integrated into your IDE. For Eclipse, see http://subclipse.tigris.org/
The advantage that svn gives you is that you can easily see the history of a file; you can easily get the latest updates (or a particular release); and you can generate patches if you change something.
All that being said, I've planning to post a release candidate in the next day or so, so I'll make one with source code then.
