Version and Release Numbers

The Xubuntu version numbering scheme is based on the date we release a version of the distribution. The version number comes from the year and month of the release rather than reflecting the actual version of the software.

The first official release of Xubuntu (Dapper Drake) was in June 2006, so its version was 6.06. This version (Jaunty Jackalope) was released in April 2009 so its version number is 9.04.
