A couple days ago, KDE 4.6 was released for the world to enjoy. It boasts myriad bug fixes, new features for applications like Dolphin and Marble (among others), a revamped Activities feature, and better integration of GTK+ applications.
I've come to enjoy testing new KDE 4 releases because it gets noticeably better with each release (or so I would hope), as opposed to GNOME, Xfce, LXDE, and other DEs which don't change much between "point" releases (i.e. X.Y ("X point Y")).
That said, it's not available for Linux Mint 9 "Isadora", and I don't plan on upgrading that until the next LTS release (Linux Mint 13 "M[...]a") unless some radical change (that I don't like) makes me switch distributions (but given the lead developer Clement Lefebvre's recent statements on the matter, that is highly unlikely). Right now, it's only (in terms of Ubuntu-based distributions) available in Ubuntu/Kubuntu 10.10 "Maverick Meerkat" and Linux Mint 10 "Julia" through a backport PPA. As I had a Linux Mint 10 "Julia" GNOME live USB handy, I used that to do testing; I will say that this method may have been the cause of many of the problems that you will read about shortly.
