The Jolicloud OS has been renamed to Joli OS, to avoid confusion with their online desktop app. With this change, the new 1.2 version was also released bringing new functionality and performance – see http://www.jolicloud.com/blog/2011/03/09/welcome-to-the-new-jolicloud/. The 1.2 version has now been adapted for the Joggler and can be downloaded from the Jolicloud page.
Ubuntu Maverick and Linux Mint have also been updated. Changes include an updated kernel (2.6.37.3) and a new btrfs with the much faster lzo compression.
