Website hasn't been updated yet, but you can find the latest release here: http://sourceforge.net/project/showfiles.php?group_id=114860
It requires at least wavpack 4.40.0 and it supports all the test samples (more than 2 channels is ignored).
Basic metadata reading is present as well.
Main site is: http://aqualung.sf.net
It's a pretty neat player, so i figured it could use an improvement from the (atm very lacking) ffmpeg decoder.
