Yep, the first alpha of 2008 Spring is out, with the latest KDE, GNOME, kernel and lots of other fun stuff. It's also unreasonably stable for a first alpha. One and Free editions are available (one of the last remaining problems in the 2008 release cycle was that we didn't do a One pre-release until the final RC, so this is good news). We (and I specifically) are particularly interested in hardware detection in this alpha, and it's really easy to test - just download One, burn it, boot it, and see if everything works. If it doesn't, file bugs!
