On May 20, Canonical published a new Ubuntu security notice where they've informed users about the immediate availability of a new kernel update for its Ubuntu 14.04 LTS (Trusty Tahr) operating system.
It's been four years and two weeks since Mark Shuttleworth expressed his goal of "200 million users of Ubuntu in 4 years." While Ubuntu's presence has continued to increase over the past four years, it doesn't look like that goal has been realized yet or will be by the end of the calendar year.
Canonical’s Łukasz Zemczak has confirmed that the next Ubuntu Touch Update (OTA 4) will be released by the end of the month and will change the code base of the system to Ubuntu 15.04 Vivid Vervet.
Ubuntu Touch is already stable, and it's available on two different phones right now, Bq Aquaris and Meizu MX4. It's different from your regular OS experience, but that's a good thing. The only real problem is the lack of apps, although a Blackberry approach to the problem might be a good thing for Canonical.
Convergence used to mean a different thing a couple of years back. We used to think that it's about turning your phone into a working PC, and that was a great idea, but that concept has been refined mostly by the need of the real world. Sure enough, Canonical could have put forth a working prototype for a phone that doubled down like a PC, but they would limit themselves.
