The OpenStack project, which powers more than 75 public and thousands of private clouds, launched the 19th version of its software this week. You’d think that after 19 updates to the open-source infrastructure platform, there really isn’t all that much new the various project teams could add, given that we’re talking about a rather stable code base here. There are actually a few new features in this release, though, as well as all the usual tweaks and feature improvements you’d expect.

While the hype around OpenStack has died down, we’re still talking about a very active open-source project. On average, there were 155 commits per day during the Stein development cycle. As far as development activity goes, that keeps OpenStack on the same level as the Linux kernel and Chromium.
