Since Xen 3.0 more than 10000 changesets went into mainstream, more than

Xen 3.3, because
"The general sentiment, including from the Xen Advisory Board, is that
sticking with 3.3 is a better indication of code maturity than a .0 release."
A third release candidate is available now.
I presented a Xen-unstable package under the topic "Xen 3.3 / 4.0 package for
trial". An updated version of this packages the third release candidate.
Download http://www.netbsd.org/~cegger/pkgsrc-xen33-18261-1.tar.gz
