Hi,
On behalf of the QEMU Team, I'd like to announce the availability of the
QEMU 1.2 release!
http://wiki.qemu.org/download/qemu-1.2.0.tar.bz2
Even though this was the shortest release cycle in QEMU's history, it
contains an impressive 1400 changesets from 180 unique authors.
See the ChangeLog on the wiki for a full changelog:
