This is the first maintenance release of Ubuntu 6.06 LTS, which continues to be supported with maintenance updates and security fixes until June 2009 (on desktops) and June 2011 (on servers).
Over 300 post-release updates have been pre-applied, so that fewer updates will need to be downloaded after installation, and a number of bugs in the installation system have been corrected. These include security updates and corrections for other high-impact bugs, with a focus on maintaining stability and compatibility with Ubuntu 6.06 LTS. We do not expect that certifications against Ubuntu 6.06 LTS will need to be updated for this maintenance release
