That’s right, we’re talking about Zorin OS 12.1, which comes three months after the launch of Zorin OS 12 in November 2016 as the biggest release ever of the Linux distro. Zorin OS 12.1 is now based on Canonical’s recently released Ubuntu 16.04.2 LTS (Xenial Xerus) operating system, which ships with updated kernel and graphics stacks from Ubuntu 16.10 (Yakkety Yak). As expected, the Zorin OS 12.1 Live ISO images come with all the latest security and software updates, which have been imported from the upstream Ubuntu repositories. These fix bugs from previous releases, but also add better hardware support and performance enhancements, so updating is highly recommended.
