+1 Subversion still lacks a few features in commit notices, and I don't see the equivalent of viewcvs diff (must be hidden somewhere), but the developer interaction is much better.
What are we going to use for trunk names? httpd-1.3 and httpd-2? I wonder how hard it would be to make cvs2svn overlay apache-1.* with httpd-2.* into one httpd repo. Probably not worth it given all of the parallel development.
