ChangeLog/1.1

System emulation

qdev properties of type hex8 and hex32 used to accept hexadecimal values not prefixed with "0x"; the prefix is mandatory starting with this version. These properties are: iobase, membase, io_base for all devices that support the properties; vram_size for sysbus-g364 and SUNW,tcx; version for sb16 and iommu; ctl_iobase and data_iobase for fw_cfg; readback for debugcon; elcr_addr and elcr_mask for i8259.
PCI addresses can still be addressed with a pair of hexadecimal device and function without a "0x" prefix.
-kernel, -initrd and -append are now aliases for suboptions of -machine (for example -machine kernel=foo), and as such they are also available with -readconfig.

The syborg machine type has been removed since the Symbian Virtual Platform is no longer relevant with the disbanding of Symbian.
A device tree can be passed to the kernel using -dtb option (or alternatively -machine dtb=...).
[new machine types]

NMIs are correctly injected through the LAPIC (rather than sent directly to the guest CPU) and respect the LINT1 mask, thus fixing kdump.
The -rtc-td-hack option is now available as a qdev property (-global mc146818rtc.lost_tick_policy=slew) and as such can be specified in a -readconfig configuration file.
[S3 support]
KVM can optionally use kernel-based emulation of the local APIC, IOAPIC and i8259 PIC. This is supported with the -machine ...,kernel_irqchip=on command-line option. MSI is not supported yet when using the kernel_irqchip option.
[pflash stuff]?

The virtio-scsi device is now supported by QEMU. The guest driver will be supported in Linux starting at version 3.4.
QEMU now includes experimental support for USB 3.0 (xHCI).

QEMU's NBD client implementation and the qemu-nbd server both fully support asynchronous I/O.

Live migration (or save/restore) from QEMU releases prior to 0.13 to QEMU 1.1 is not supported
