Mark Shuttleworth announced on 21 April 2016 that Ubuntu 16.10 would be called Yakkety Yak. It was released on 13 October 2016.
This release features a maintenance version of Unity 7, but offers Unity 8 packages included in the ISO, so that users can test them. Other improvements include a new version of Ubuntu Software that supports faster loading, better support for installing command-line-only non-GUI applications, support for installing fonts and multimedia codecs and introduction of paid applications. It is based on Linux kernel version 4.8.
This version of Ubuntu introduced only minor incremental changes. These included LibreOffice 5.2, GTK3 version by default, the Update Manager shows changelog entries for Personal Package Archives (PPAs), as well as repository software, GNOME applications updated to version 3.20, with some using version 3.22. Also, systemd now handles user sessions as well as the previously implemented system sessions.
Joey Sneddon of OMG Ubuntu said, "Ubuntu 16.10 is not a big update over Ubuntu 16.04 LTS, released back in April. If you were hoping it'd be a compelling or must-have upgrade you'll be sadly disappointed." He did find some improvements, "The Ubuntu Software app is also significantly faster in use. This solves a real pet peeve of mine on the incumbent LTS desktop. Thankfully, Yakkety makes it quicker to find, browser, search and install applications," but concluded, "Ubuntu 16.10 is not a must-have upgrade—not for most people."
Marius Nestor of Softpedia noted, "Ubuntu 16.10 is not an exciting release for fans of the open source operating system. Probably the most important feature of Yakkety Yak is Linux kernel 4.8, which brings support for the latest hardware, but other than that, you'll get some updated components that are mostly based on the old GNOME 3.20 Stack."
Writing in Makeuseof, Bertel King, Jr. said, "If you're feeling underwhelmed, you probably remember the Ubuntu of yesteryear. Back in the days of 8.10, 9.04, and 10.04 each release brought forth a new theme or ambitious feature. Unity first appeared in 10.10 as a netbook interface before replacing the regular desktop in 11.04. By comparison, modern Ubuntu updates feel relatively stagnant. You would be forgiven for not being able to distinguish between 12.04 and 16.10."
