"In the nine-year history of Ubuntu Linux, a new version of the
operating system has come out every six months. But Canonical,
Ubuntu's developer, is considering ditching that model in favor of one
that produces an entirely new version only once every two years—while
speeding up the overall pace of development by adopting a "rolling
release" cycle in between."
