Subversion 1.2 Release Candicate 1 has been released. According to the release notes, there's some really interesting new stuff. E.g. a locking feature (a.k.a. reserved checkouts), a faster xdelta binary-differencing algorithm (instead of vdelta), FSFS repositories are now the default, and the usual bugfixes.
Regarding the xdelta: dumping and reloading your repositories will convert them to xdelta and make them a bit larger, but will also make operations such as svn co, svn up and svn diff a lot faster, which is great.
