PCLinuxOS 2014.07 Arrives with Linux Kernel 3.15.4 and KDE 4.12.3 – Gallery
PCLinuxOS comes with many flavors, but the default is actually KDE. The developers also make a few other versions, like KDE MiniMe, LXDE, or FullMonty, but this is the main one downloaded by most users.
The distribution actually follows a rolling release model, which means that new major features and other changes are introduced regularly through the update channel. Every month, the download ISOs are regenerated with the new update, but if you already have the operating system installed you only have to update it regularly.
