Hi,

On behalf of the QEMU Team, I'd like to announce the availability of the
QEMU 1.3 release!

http://wiki.qemu.org/download/qemu-1.3.0.tar.bz2

This release contains over 1700 changesets from 118 unique authors.

See the ChangeLog on the wiki for a full changelog:

http://wiki.qemu.org/ChangeLog/1.3

Major features include:
 - After nearly 6 years of work, all remaining differences between the
   qemu-kvm.git and qemu.git have been merged into qemu.git
 - QEMU can now use the Linux VFIO driver to assign PCI devices to a virtual 
machine.
 - USB3 has been vastly improved, including support for USB mass storage
   devices and MSI/MSI-X support for the XHCI controller.
 - New paravirtualized hardware random number generator device.
 - Glusterfs volumes can be accessed with "gluster://" URIs for "-drive"
   and similar options. Optionally the transport can also be specified, as
   in "gluster+tcp://" (other supported transports are "unix" and "rdma").
 - A new block job is supported: live block commit (also known as
   "snapshot deletion") moves data from an image to another in the backing
   file chain.
 - A new block job is supported: live disk mirroring (also known as
   "storage migration") moves data from an image to another.
 - The sendkey monitor command is now available via QMP.
 - MIP Loongson Multimedia Instructions are now implemented.
 - MIPS32/64 ASE DSP Instructions are now implemented.
 - x86: the TSC frequency can be larger than 2.147 GHz.
 - TCG (emulation) supports the SMEP (Supervisor Mode Execution
   Prevention) and SMAP (Supervisor Mode Access Prevention) features of
   newer x86 processors.
 - New CPU models: "Haswell" and "Opteron_G5"
 - xtensa: Single precision floating point instructions are now implemented.
 - Emulation of the MC146818 real-time clock (used on PC and several
   other boards) does not wake up QEMU anymore every second to update the
   clock.
 - USB redirection now supports live migration.
 - Several bugs in the AHCI controller were fixed to support recent Windows 
versions.
 - qemu-img now can output information in JSON format using "qemu-img info 
--output=json".
 - NBD block devices can now be specified using URI syntax.  "nbd://"
   defaults to TCP transport, while "nbd+tcp://" and "nbd+unix://" can be
   used (similar to Gluster) to specify it.
 - QEMU embeds an NBD server, accessible via the monitor.
 - Windows hosts support asynchronous disk I/O.
 - The monitor now remains responsive during incoming migration.  The
   new NBD server is also available during incoming migration.
 - spice: QEMU will only send changed screen content to the Spice client
   when running in legacy VGA mode.
 - Improved support for sandboxing using seccomp mode 2 with libvirt

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
