[Qemu-devel] [ANNOUNCE] QEMU 2.11.1 Stable released

[Michael Roth]

Hi everyone,

I am pleased to announce that the QEMU v2.11.1 stable release is now
available:

You can grab the tarball from our download page here:

  https://www.qemu.org/download/#source

v2.11.1 is now tagged in the official qemu.git repository,
and the stable-2.11 branch has been updated accordingly:

  https://git.qemu.org/?p=qemu.git;a=shortlog;h=refs/heads/stable-2.11

This update contains new functionality needed to enable mitigations for
Spectre/Meltdown (CVE-2017-5715) in x86, pseries, and s390x QEMU/KVM
guest operating systems. Documentation for the various options/requirements
for enabling this functionality is available here:

  https://www.qemu.org/2018/02/14/qemu-2-11-1-and-spectre-update/

There are also security fixes for potential host DoS attacks via
VGA devices (CVE-2018-5683) and VNC clients (CVE-2017-15124), as
well as the normal range of general fixes. Please see the changelog
for additional details and update accordingly.

Thank you to everyone involved!
