We switched to the new Allura platform here on Sourceforge.
You have to relocate your working copies [1] to get the latest commits.
For details see the SVN section and choose "Code".
[1] SVN 1.7: http://svnbook.red-bean.com/en/1.7/svn-book.html#svn.ref.svn.c.relocate
SVN 1.6: http://svnbook.red-bean.com/en/1.6/svn-book.html#svn.ref.svn.c.switch
We are planning to switch to Subversion when the new deploy environment of Sourceforge with SVN+SSH support is in place.
The active repository will still be the CVS repository until then.
If you find a Subversion repository here on Sourceforge, then this is just a playground to test the conversion. So, do not use it.
