Hi,
On behalf of the QEMU Team, I'd like to announce the availability of the
QEMU 1.4 release!
http://wiki.qemu.org/download/qemu-1.4.0.tar.bz2
Even though this was our shortest release cycle in the history of the
project, this release contains almost 1400 changesets from 116 unique
authors.
Major features include:
* block: experimental threaded backend for virtio-blk-pci achieving up
to a 900% increase in IOP rate on very large storage devices.
* migration: threaded live migration, improving latency in other parts
of QEMU and throughput of migration itself
* usb: usb-tablet can be connected as an USB 2.0 device, lowering the CPU
usage substantially
* usb: improved support for pass-through of USB serial devices
* virtio-net: added support supports multiqueue operation
* s390: new virtio-ccw machine and transport support
* x86: experimental AHCI migration support and support for device
assignment for the q35 chipset
* qmp: support for hotplugging character devices
And more...
See the ChangeLog on the wiki for a full changelog:

I'd like to thank everyone who contributed to this release by submitting
patches, testing out -rcs, or reporting bugs during the release process!
Regards,
Anthony Liguori
