On behalf of the QEMU Team, I'd like to announce the availability of
the QEMU 2.0.0 release.  This is one of our most extensive releases ever, with
2,500+ commmits from 179 authors.


The full list of changes are available at:


Highlights include:

 * Initial support for KVM on AArch64 systems (some features such as migration
   are not yet implemented)
 * Support for all 64-bit mode ARMV8 user-accessible instructions except for
   the optional CRC and crypto extensions
 * Support for new 32-bit mode ARMv8 instructions in TCG
 * Support for the allwinner-a10-based board "-M cubieboard"
 * Support for POWER Altivec 2.07 and VSX instructions when running under TCG
 * Support for boot order in pSeries emulation
 * The Q35 x86 machine-type now supports CPU hotplug.
 * On the PIIX x86 machine-type, PCI hotplug now supports devices behind a
   bridge (for bridges not added by hotplug; hot-plugged bridges can still use
   the PCI Standard Hot-Plug Controller)
 * Support for the Hyper-V reference time counter via the "hv-time" suboption
   of "-cpu". This can improve performance of Windows guests substantially for
   applications that do many floating-point or SIMD operations. (Requires KVM
   and Linux 3.14).
 * ACPI tables generated by QEMU can now be used by OVMF
   (https://wiki.ubuntu.com/UEFI/OVMF) firmware. OVMF starting with SVN r15420
   is needed. In particular hotplug, pvpanic device and other ACPI based
   features now work for OVMF
 * PCI passthrough of devices with a ROM now work on Xen
 * support for suspend-to-RAM in the XHCI USB controller
 * GTK UI is now supported on Windows hosts
 * New management interfaces for CPU and virtio-rng hotplug
 * Improved reliability for live migration when using qcow2 images
 * Live snapshot merging
 * Experimental support in virtio-blk for M:N threading model: if you specify
   x-dataplane=on, you can also create I/O threads with "-object iothread" and
   point virtio-blk devices to the desired iothread with the "x-iothread"
   property. Properties of the running iothreads can be queried with the QMP
   command "query-iothreads".
 * Network block drivers (curl, iscsi, rbd, ssh, glusterfs) can be built as
   shared library modules with "--enable-modules" configure option.
 * QEMU is now able to operate even if the underlying storage requires the
   buffer size to be a 4K multiple. This is the case for 4K-native disks (with
   cache=none or when accessed through iscsi:// URLs) and some raw devices
 * QEMU can access NFSv3 shares directly from userspace using libnfs.
 * Improvements to the TCG optimizer make it produce faster code
 * Tracing QEMU via LTTng 2.x is now supported
 * And lots more...

Thank you to everyone involved!
