The Zorin OS 15 series, released last week in beta, introduces many changes to its desktop interface and utilities. It keeps Zorin on track with its goal of maintaining a Linux OS for everyone, not just advanced Linux users. Zorin OS 15 beta is the first major release since Zorin OS 12 in late 2016. This edition is well worth the wait. Major releases of Zorin OS come only once every two years. Minor updates are released every few months as needed. Zorin OS 15 is based on Ubuntu 18.04.2 Long Term Support.
