Given how similar Puppy 2.14 was to 2.13, I was wholly unprepared for how different the latest Puppy release, 2.15CE (community edition), is from its predecessors.
First of all, it looks completely different. That's because IceWM is the default window manager for Puppy 2.15, although the old standby JWM (Joe's Window Manager) is still available. And aside from the radical change in GUI, the desktop background is darker (and less "puppy" themed) than in distros past. Still, the Menu key on the bottom left does have a paw print.
Under Settings-Themes in the main Puppy menu (accessible, as always, by right-clicking anywhere on the screen), you can alter the look of your desktop very easily.
Under IceWM, Puppy remains lightning-fast -- it sure was on my Dell 3 GHz Optiplex GX520 with 512 MB RAM.
All my configuration information from the previous Puppy version was picked up from my pup_save.sfs file when I booted 2.15 for the first time, so my networking, screen resolution and printing were already set up.
