I replied in advance to this question in a thread not long ago: "the end of SCM."
The obvious novelty is the success of Git and Mercurial, following Subversion.
It is worth examining this situation on several aspects.
1. These are tools created by the authors of successful Open Source projects (Apache, Linux kernel, Firefox) for their own needs.
2. This is a powerful statement about the inadequacy of the offering, hence of the state of SCM.
3. Their creations are novel in relatively modest ways: for the most, they build up a return back to the basics of source control, which Linus Torvalds termed "source archiving and distribution."
