A new release of the Ubuntu Enterprise Cloud Images for stable Ubuntu
release 10.04 LTS (Lucid Lynx) is available at [1].  Images are available
for download or immediate use on EC2 via published AMI ids.

There are a few important updates since the 20101228 release [2].
 * Images now use pv-grub kernels [3] by default.
   This means that if you launch an instance of the new AMIs, or rebundle
   based on these images, you can upgrade and reboot into a new kernel.

   Future kernels updates can be obtained via:
     sudo apt-get update && sudo apt-get dist-upgrade
     sudo reboot

   Previously receiving a kernel upgrade required either a rebundle, or
   on EBS root instances, a stop, modify-instance-attribute, and start.

   Ubuntu will continue to publish kernel AKIs for 10.04 kernels.
   However, these AKIs will be only useful if you are not using or basing
   your images off the official images.

 * linux-image-2.6.32-312-ec2 [4] and linux-image-2.6.32-28-virtual [5]
   were updated to address dozens of bugs and 4 CVEs
   (CVE-2010-4165, CVE-2010-4169, CVE-2010-4249, CVE-2010-0435)
   A complete changelog can be seen at [6]

 * The following CVE are addressed
   * util-linux: CVE-2010-3879
   * dpkg: CVE-2010-1679
   * dbus: CVE-2010-4352
   * sudo: CVE-2011-0010
   * eglibc: CVE-2010-3856
   * fuse: CVE-2010-3879

If you are using a previous release, you should update in order to receive
the kernel change.  The kernel cannot be changed in previous 10.04 based
images by package upgrade.

The biggest single reason to upgrade your image is the ability to obtain
kernel upgrades in the future.

Other changes can be obtained via software update. The only cost is in
time to perform the update.

The following is a complete list of changes in the included packages.
