[Qemu-devel] [ANNOUNCE] Release 0.12.1 of QEMU

[Anthony Liguori]

The QEMU team is pleased to announce the availability of the 0.12.1.
release.  This is the first release of the 0.12 series.  0.12.0 had a 
problem with target-arm we felt was important enough but found after 
0.12.0 was tagged.  This has been fixed for 0.12.1.

This release consists of over 2,000 commits from 99 contributors.

Some major features were added in this release including:

 - target-arm: FP16 and Cortex-A9 cpu support
 - target-i386: change bios from PC-BIOS to SeaBIOS
 - target-i386: change netboot roms from etherboot to gPXE
 - target-i386: remove kqemu support
 - target-s390: introduce new s390 target (KVM-only)
 - live migration: support migration with non shared storage
 - live migration: make save/restore data driven (VMState)
 - monitor: introduce machine-protocol (QMP)
 - qdev: convert many devices, support reading config from file
 - pci: infrastructure to support 64-bit busses
 - net: introduce -netdev to support point-to-point networking
 - net: add support for GSO and checksum offload
 - tons of bug fixes throughout the code base

A detailed change log since 0.12.0-rc2 is included below.

On behalf of the QEMU team, I'd like to thank everyone who contributed
to make this release happen!

A special note about kqemu support:  While we understand that many users 
appreciated kqemu, it has not seen active development for a few years 
now.  Besides many known bugs, it was causing regressions for non-kqemu 
users.

Back in the 0.10 release cycle, we set a deprecation/removal schedule 
unless someone stepped up to fix and maintain kqemu.  Since no one was 
willing to fix and maintain kqemu, we removed it for 0.12.  If someone 
is willing to fix the problems with kqemu and actively maintain it, we 
would happily reintroduce support for it.
