There is only one issue open against 1.8.0: http://subversion.tigris.org/issues/show_bug.cgi?id=4358
Based on what I understand I believe that issue can be moved to some future target since the conclusion seems to be it's not a blocker. There are some changes in STATUS that we should finish voting for. Of particular note is Branko's case-sensitivity change. Unless someone is aware of something else, once we wrap up some of the STATUS changes I think we can cut a release candidate for 1.8.0, probably this week?
