This new release comes with all the bits and pieces you expect from a modern Linux distribution: Linux kernel 18.104.22.168.tex3, KDE 3.5.10, OpenOffice.org 3.0, Firefox 3.0.7, Thunderbird 22.214.171.124, Ktorrent, Frostwire, Amarok, Flash, Java JRE, Compiz-Fusion 3D, and loads of other stuff. The pclos-gnome team has also put out its 2009.1 release, which is essentially the same except for the inclusion of GNOME 2.24.3.
It's interesting to note the KDE version included: KDE 3.5.10. PCLinuxOS is a KDE-centric distribution, so why aren't they focussing on the latest and greatest in KDE land? The team explains: "We decided to use KDE 3.5.10 as our default desktop as we could not achieve a similar functionality from KDE4." The team does, however, promise to make KDE4 available in the repositories once they "stabalise it".
If you prefer KDE 3.x over KDE4, PCLinuxOS is a good choice, as it's probably one of the few more major distributions left out there still focussing on KDE 3.x. Download away!
