It could be down to the summer holidays, but if that were the case we would be be seeing loads of distros from Australia. It could be the lull before the storm, as some of the major distros are at the beta test stage. It could be the ‘Ubuntu effect’ – so many distros are based on Ubuntu nowadays that there’s always a flurry of releases in the month or so following an official Ubuntu release. Or it could be that everyone is too busy re-evaluating their encryption and security options to get on with any coding (thanks a bunch NSA). This is a good time of year to release a new distro, because there’s far more chance of being noticed than among the clamour at the end of every April and October. This situation makes it more difficult to find something good for the DVD, but also makes the task This is another distribution that is meant to be able – it’s so fast and smooth.
