QEMU v0.15.0 is released. QEMU is a generic and open source machine emulator and virtualizer.When used as a machine emulator, QEMU can run OSes and programs made for one machine (e.g. an ARM board) on a different machine (e.g. your own PC). By using dynamic translation, it achieves very good performances.When used as a virtualizer, QEMU achieves near native performances by executing the guest code directly on the host CPU. A host driver called the QEMU accelerator (also known as KQEMU) is needed in this case. The virtualizer mode requires that both the host and guest machine use x86 compatible processors.

After two versions of "Release Candidate", that the advent of version 0.15.0 stable. The changes are those of the two "RC" above.

Targets:
- New targets: LatticeMico32 and UniCore32.
- ARM: fixed many bugs in Neon, correction instructions ARMv6 and ARMv7.
- ARM floating point instructions correctly handle NaNs and status indicators float.
- ARM: implementation of "dummy" performance counters CP15 and CP14 registers debugger. Now you can run the latest Linux kernels that probe these functions.
- ARM: added support of SA-1110/SA-1100.
- ARM: new models of machines: ARM Versatile Express (machine "vexpress-a9"), Sharp Zaurus SL-5500 (machine "collie").
- Sparc32: openbios improvements to enable the launch of Solaris 8.
- SPARC64: corrections and instructions sdivx udivx, Helenus ability to run with the command prompt.
- Sparc32: some minor fixes.
- SPARC64: some minor fixes.
- LM32: basic support for scalable map LM32 EVR.
- LM32: Milkymist SoC support including video rendering.
- LM32: test suite of almost all the opcodes.

Hosts:
- ARM: support C code compiled QEMU host in the Thumb mode.

KVM:
- General: corrections of countless porting QEMU-KVM, the kernel is now shared with the tree, that is to say it has the same qualities.
- General: full tree sync QEMU-KVM.
- General: removing dependencies on external kernel headers, all the services supported in KVM are now integrated into the executable.
- X86: fixes Paravirtual kvmclock.
- X86: migration of the guest stable through TSC.
- X86: support for the CPU SMEP.
- X86: support for the CPU VIA.
- X86: fix support ERM.

Peripherals:
- Virtio-series: various fixes to hotplug ports.
- Virtio-series: the port number 0 is reserved for the console ports for backward compatibility, 'device-virtserialport, nr = 0' no longer allowed.
- Virtio-series: an ability to reuse a port chardev after the user has been disconnected.
- Virtio-series: Added tracing events.
- CTS: MC146818 (for PC), reset the clock host.
- Balloon: Fixed a problem that crashed QRMU on the issue of 'balloon 0' in the monitor.
- Balloon: balloon multiple devices are now banned.
- Balloon: balloon negative values ​​are rejected.
- Balloon: Fixed memory leaks in the closure or disconnection of the device-balloon virtio.
- Balloon: correction of the migration after disconnecting the device virtio-balloon.

Block layer:
- Added missing-drive options in the main window.
- Support Catch live in QMP by using the snapshot-blkdev-sync.
- Fixed support for removable media not to cache the size of the media. Before this fix, the operating system of the guest saw the size of the old CD even after changing media.
- QEMU-img: conversion and rebase now support the-p option that allows you to see the progress.
- QEMU-img: commit, rebase and conversion now support the-t option that allows you to specify a cache that must be used when opening an image.
- QEMU-img: improving the performance of the conversion of a QEMU-img.

- IDE Emulation: separation of the components ide-hd and ide-cd.
- IDE emulation: fix confusion between the registry's status Busmaster IDE and the state of internal error, which led to a crash.
- Emulation CD-ROM: several fixes to comply with the ATAPI specification.
- Emulation CD-ROM: GET_EVENT_STATUS_NOTIFICATION, implementation of the sub-command 'media' which, for guests, using the ratio of open / close the valve and for the status absent / present media. New guest Linux (kernel 6.2.38 +) account on this command to re-validate the record.
- Emulation CD-ROM: code cleanup and reconstruction.
