Zorin OS 10 is powered by Ubuntu’s Linux 3.19 kernel and systemd init system and service manager, and comes with Zorin Web Browser Manager, a tool that allows users to install additional web browsers in the distribution. Another big change in Zorin OS 10 is the default set of applications, which now include the awesome Geary Mail client, a Calendar app, an Activity Journal software, a streamined Media Player, and many more that you will have to discover for yourself when using the operating system.
