Sounds like a bug. :-) I realize that is a rather simplistic view, but the reality is that we want the best of both worlds: we like having active feaure merging, and we like having multiple active branches with releases after a .0. In fact, having a .4 on one branch after a .0 on the next branch seems pretty central to our world view. As many downsides as library versions had, one upside was the ability to do this. I need to go read Alexander's e-mail, but it seems that really this limitation shouldn't have to exist. Robert N M Watson Computer Laboratory University of Cambridge
