Yes, a summary changelog would be nice.  I'm looking for it so I can
look for possible features that I do not know exist yet and then try to
find out how to use it from the code :)

I guess i'll have to rely on my own testing then :)  I was just

I do have one technical question, has anyone used any other method of
virtual disks besides the one included (ie. loopback files, LVM) ?
Pardon me not trying this out first, i'm still building the Xen /
XenoLinux images on my (slow) test box.
