The latest release of Fedora, nicknamed “Heisenbug,” is a step towards making Fedora a player in the mobile arena. Fedora 20 also includes more support for cloud, and this is also the first release that supports cheap, low-power ARM processors. The default desktop environment is Gnome 3, though Fedora also supports the Cinnamon, Enlightenment, KDE, Mate and Sugar desktops. Fedora comes with Firefox, LibreOffice, the Evolution email client, and the Empathy IM platform that can access Gmail, MSN, Yahoo!, Jabber and others. Here are 5 things we like and 5 things we don’t about Fedora 20.
