We are now at patch level 7.3.931. In a few weeks we would reach 999. I don't want to find out what happens if we go over that, so it's time for Vim 7.4!
Vim 7.4 is exciting, but if you're interested in the underlying current of patches that are regularly contributed, take a look at vim_dev. You'll see a flood of activity in response to the Python integration comment in the 7.4 announcement.
