Welcome to this year's 16th issue of DistroWatch Weekly! It's the Ubuntu release week (or Ubuntu "circus", as some prefer to call it), a major event in the calendar of many open source software enthusiasts. Mandriva gains support for hardware database known as Smolt, Easy Peasy ponders a few ideas concerning the distro's default user interface, and Fedora's Ricky Zhou points out the importance of innovation in Red Hat's community distribution. Finally, don't miss our feature article which calls for an implementation of a centralised bug-tracking database for all open source software projects.
