Last night I set up SCM (using Subversion) for the first time in Xcode. It's working fine, but I'm unable to view all the revisions for my project. In the SCM menu, I can see one or two sometimes, and in the project's "Get Info" palette, under the SCM tab, there are one or two more. Only problem is, "one or two" isn't how many revisions I've committed (which should be around 8-10 by now). Is there some setting I need to adjust, or am I not using it correctly?
