If a bug is found in SimpleTest, chances are it'll get corrected inside the Subversion (SVN) tree with the corresponding test case : just to make sure the bug doesn't make a come back later on.

Also the SimpleTest SVN trunk is usually full of little known experiments with code : new ideas are usually tried out there before a general release. Before it happens, the documentation needs to be completed : that's where this section comes into place. You'll find here new features the dev team is happy with : we're looking for comments...

The mailing-list is usually the best place to give feedback. Other options includes submitting a bug or a patch directly on the Sourceforge trackers...

Note : some of these features may never make it to a release or not for a long time!
