https://www.qemu.org/2019/08/16/qemu-4-1-0/

Highlights include:

    ARM: FPU emulation support for Cortex-M CPUs, FPU fixes for Cortex-R5F
    ARM: ARMv8.5-RNG extension support for CPU-generated random numbers
    ARM: board build options now configurable via new Kconfig-based system
    ARM: Exynos4210 SoC model now supports PL330 DMA controllers
    MIPS: improved emulation performance of numerous MSA instructions, mostly integer and data permuting operations
    MIPS: improved support for MSA ASE instructions on big-endian hosts, handling for ‘division by zero’ cases now matches reference hardware
    PowerPC: pseries: support for NVIDIA V100 GPU/NVLink2 passthrough via VFIO
    PowerPC: pseries: in-kernel acceleration for XIVE interrupt controller
    PowerPC: pseries: supporting for hot-plugging PCI host bridges
    PowerPC: emulation optimizations for vector (Altivec/VSX) instructions
    RISC-V: support for new “spike” machine model
    RISC-V: ISA 1.11.0 support for privileged architectures
    RISC-V: improvements for 32-bit syscall ABI, illegal instruction handling, and built-in debugger
    RISC-V: support for CPU topology in device trees
    s390: bios support for booting from ECKD DASD assigned to guest via vfio-ccw
    s390: emulation support for all “Vector Facility” instructions
    s390: additional facilities and support for gen15 machines, including support for AP Queue Interruption Facility for using interrupts for vfio-ap devices
    SPARC: sun4m: sun4u: fixes when running with -vga none (OpenBIOS)
    x86: emulation support for new Hygon Dhyana and Intel SnowRidge CPU models
    x86: emulation support for RDRAND extension
    x86: md-clear/mds-no feature flags, for detection/mitigation of MDS vulnerabilities (CVE-2018-12126, CVE-2018-12127, CVE-2018-12130, CVE-2019-11091)
    x86: CPU die topology now configurable using -smp …,dies=
    Xtensa: support for memory protection unit (MPU) option
    Xtensa: support for Exclusive Access option
    GUI: virtio-gpu 2D/3D rendering may now be offloaded to an external vhost-user process, such as QEMU vhost-user-gpu
    GUI: semihosting output can now be redirected to a chardev backend
    qemu-img: added a –salvage option to qemu-img convert, which prevents the conversion process from aborting on I/O errors (can be used for example to salvage partially corrupted qcow2 files)
    qemu-img: qemu-img rebase works now even when the input file doesn’t have a backing file yet
    VMDK block driver now has read-only support for the seSparse subformat
    GPIO: support for SiFive GPIO controller
    and lots more…

Thank you to everyone involved!

Retroactively adding change notes and a promotion due to security fixes. Also, moving milestone back to 9.0.
