Hello,
On behalf of the QEMU Team, I'd like to announce the availability of
the QEMU 2.12.0 release. This release contains 2700+ commits from 204
authors.
You can grab the tarball from our download page here:
https://www.qemu.org/download/#source
The full list of changes are available at:
https://wiki.qemu.org/ChangeLog/2.12
Highlights include:
* Spectre/Meltdown mitigation support for x86/pseries/s390 guests. For
more details see:

* Numerous block support improvements, including support for directly
interacting with userspace NVMe driver, and general improvements to
NBD server/client including more efficient reads of sparse files
* Networking support for VMWare paravirtualized RDMA device (RDMA
HCA and Soft-RoCE supported), CAN bus support via Linux SocketCAN and
SJA1000-based PCI interfaces, and general improvements for dual-stack
IPv4/IPv6 environments
* GUI security/bug fixes, dmabufs support for GTK/Spice.
* Better IPMI support for Platform Events and SEL logging in internal
BMC emulation
* SMBIOS support for "OEM Strings", which can be used for automating
guest image activation without relying on network-based querying
* KVM support for systems larger than 7.999TB
* Disk cache information via virtio-balloon
* ARM: AArch64 new instructions for FCMA/RDM and SIMD/FP16/crypto/complex
number extensions
* ARM: initial support for Raspberry Pi 3 machine type

* PowerPC: PPC4xx emulation improvements, including I2C bus support
* PowerPC: new Sam460ex machine type
* PowerPC: significant TCG performance improvements
* PowerPC: pseries: support for Spectre/Meltdown mitigations
* RISC-V: new RISC-V target via "spike_v1.9.1", "spike_v1.10", and "virt"
machine types
* s390: non-virtual devices no longer require dedicated channel subsystem
and guest support for multiple CSSs
* s390: general PCI improvements, MSI-X support for virtio-pci devices
* s390: improved TCG emulation support
* SPARC: sun4u power device emulation
* SPARC: improved trace-event support and emulation/debug fixes
* Tricore: new instruction variants for JEQ/JNE and 64-bit MOV
* x86: Intel IOMMU support for 48-bit addresses
