1. ABOUT THIS RELEASE

The current update for the Virtuozzo Containers 4.0 kernel provides a new
kernel based on the SUSE Linux Enterprise Server 10 Service Pack 3 kernel
(2.6.16.60-0.59.1).

--------------------------------------------------------------------------------

2. UPDATES DESCRIPTION

The updated kernel includes many important security and stability fixes as
compared to the previous kernel based on the SUSE Linux Enterprise Server
kernel. It also includes fixes specific for Parallels Virtuozzo Containers.

We highly recommend that all Parallels Virtuozzo Containers 4.0 users were
running servers with the SLES-based kernel installed update their kernel to the
latest version.
