Today, we're announcing write support for our previously released Subversion support
To try it out, just use your GitHub credentials on a Subversion URL:
Update: Subversion support has been upgraded. Projects should be checked out from github.com rather than svn.github.com:
svn checkout https://github.com/schacon/kidgloves
Because of the way SVN expects on-server merges, you may see some strange looking merge history when working with someone using Subversion.
Annotations and some types of diffs still won't work properly yet - we're working on it.
You cannot checkout parts of a repo (such as subdirectories) or branches other than the default branch on GitHub (yet).
You currently have to have a 'master' branch
Finally, this is currently considered beta functionality - you are taking a certain risk allowing Subversion to modify bits in your code. Test it out and see if it works for you.
