We are pleased to announce the availability of the Xen 4.1.1 maintenance
release, the first maintenance release of the Xen 4.1 series. The
release can be downloaded from the download pages

Xen 4.1.1 sports the following changes:
* Security fixes including CVE-2011-1583 CVE-2011-1898
* Enhancements to guest introspection (VM single stepping support
for very fine-grained access control)
* Many stability improvements, such as: PV-on-HVM stability fixes
(fixing some IRQ issues), XSAVE cpu feature support for PV guests
(allows safe use of latest multimedia instructions), RAS fixes for
high availability, fixes for offlining bad pages and changes to
libxc, mainly of benefit to libvirt
* Compatibility fixes for newer Linux guests, newer compilers, some
old guest savefiles, newer Python, grub2, some hardware/BIOS bugs.
For those yet to make the jump to the Xen 4.1 series, we have also made
available Xen 4.0.2 <http://xen.org/download/index_4.0.2.html>, a
