The Ubuntu team has released the first maintence update to Dapper Drake: 6.06.1. Lots of patches & updates in this one:

"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."
