Hello,
On behalf of the QEMU Team, I'd like to announce the availability of
the QEMU 3.0.0 release. This release contains 2300+ commits from 169
authors.
A note from the maintainer:
Why 3.0? Well, we felt that our version numbers were getting a bit
unwieldy, and since this year is QEMU's 15th birthday it seemed like
a good excuse to roll over the major digit. Going forward we plan to
increment the major version once a year, for the first release of the
year. Don't read too much into it: it doesn't imply a drastic
compatibility break.
Rumours of our triskaidekaphobia have been greatly exaggerated :-)
You can grab the tarball from our download page here:

The full list of changes are available at:
https://wiki.qemu.org/ChangeLog/3.0
Highlights include:
* Support for additional x86/AMD mitigations against Speculative
Store Bypass (Spectre Variant 4, CVE-2018-3639)
* Improved support for nested KVM guests running on Hyper-V
* Block device support for active disk-mirroring, which avoids
convergence issues which may arise when doing passive/background
mirroring of busy devices.
* Improved support for AHCI emulation, SCSI emulation, and persistent
reservations / cluster management.
* OpenGL ES support for SDL front-end, additional framebuffer
device options for early boot display without using legacy VGA
emulation
* Live migration support for TPM TIS devices, capping bandwidth
usage during post-copy migration, and recovering from a failed
post-copy migration
* Improved latency when using user-mode networking / SLIRP
* ARM: support for SMMUv3 IOMMU when using 'virt' machine type
* ARM: v8M extensions for VLLDM and VLSTM floating-point instructions,
and improved support for AArch64 v8.2 FP16 extensions
* ARM: support for Scalable Vector Extensions in linux-user mode
* Microblaze: support for 64-bit address sizes and translation bug
fixes
* PowerPC: PMU support for mac99 machine type and improvements for
Uninorth PCI host bridge emulation for Mac machine types
* PowerPC: preliminary support for emulating POWER9 hash MMU mode when
using powernv machine type.
* RISC-V: improvement for privileged ISA emulation
* s390: support for z14 ZR1 CPU model
* s390: bpb/ppa15 Spectre mitigations enabled by default for z196 and
later CPU models
* s390: support for configuring consoles via -serial options
* and lots more...
Thank you to everyone involved!
