I also agree with Martin's points, and I also think it would be nice to have a 
stable branch for back porting bug fixes. We would then need a buildbot for 
both the development branch and the stable branch. 

I guess we also need to establish a policy for what bug fixes should be 
backported? A simple rule would be to backport only critical bugs, which does 
not change the syntax. 

What is the preffered way of cherry picking revisions from the development 
version into a stable branch? Would it be:

  bzr merge -r 6003 ../trunk
