[Qemu-devel] [ANNOUNCE] QEMU 2.9.0-rc1 is now available

[Michael Roth]

Hello,

On behalf of the QEMU Team, I'd like to announce the availability of the
second release candidate for the QEMU 2.9 release.  This release is meant
for testing purposes and should not be used in a production environment.

A note from the maintainer:

  This release candidate includes changes to the configure script
  so that it will now report some host operating systems and
  platforms as "unsupported". These are host setups which we do not
  have access to and are thus unable to test. They will continue
  to work in this 2.9 release (though configure will warn you about
  the unsupported status), but in a future QEMU release we may
  drop support for those hosts unless somebody volunteers to help
  us with maintaining them (and can provide build/CI machines).
  
  This affects the CPU architectures:
       * ia64
       * sparc
  and the OSes:
       * GNU/kFreeBSD
       * DragonFly BSD
       * NetBSD
       * OpenBSD
       * Solaris
       * AIX
       * Haiku
  (We've been fairly ruthless here in marking unsupported anything
  that we don't have working build/test support for right now. We
  may move some of these back to the 'supported' category before
  2.9 final release if we get help in getting them working. In any
  case they will still work in 2.9 as well as they ever have;
  configure will just be noisy about them.)

You can help improve the quality of the QEMU 2.9 release by testing this
release and reporting bugs on Launchpad:

The release plan, as well a documented known issues for release
candidates, are available at:

  http://wiki.qemu.org/Planning/2.9

The dates have all been pushed back a week due to delays with the
initial RC.
