Re: [Xen-users] Re: Xen and gnu gpl

[Mark Williamson <mark.williamson@xxxxxxxxxxxx>]

Try digging for the previous release announcements and see what the features 
in each release were.

You might want to search the Slashdot archives (really!) since many of the 
early releases popped up as articles there.  You might also want to look at 
the tags in the hg repository for Xen, which generally correspond to releases 
and release candidates.

For example: Xen 2.0 introduced the "new IO" model (drivers in guests, not Xen 
itself), Xen 3.0 introduced SMP.  If you dig through the release announcements 
you should be able to find out where Live Migration was added, where x86_64 
support was added, etc etc.

Cheers,
Mark
