Zorin OS was released earlier today with a handful of changes including a redesigned Zorin theme changer (GTK changer), new icons based off of the beautiful Elementary icon set and the Freesans desktop font. Zorin now comes with the Geary mail client, a new media player, a new calendar app and an activity journal “which lets you see the files and documents you have worked with based on duration and the time throughout the day”. The existing apps have been treated with bug fixes and design updates. The long awaited theme changer update adds more customization with the ability to chose the foreground color and background color. The options for foreground colors are red, green, blue and orange and you can choose between a light and a dark foreground. Zorin OS 10 is now based of off Ubuntu 15.04 and has Linux kernel 3.19 and systemd for hardware support improvements. Currently only the Core and Ultimate versions are available but Business and Lite versions will be added soon. Zorin OS 10 will get security updates until January, so if that is an important factor for you consider Zorin OS 9 which will be supported until April of 2019. You can get Zorin OS here.
