LOL why do you care what version number it is? They could switch to using letters, I wouldn't give a shit.

The part that's cool is rolling updates. It just doesn't make sense to have a release schedule like they did. The reason why software had that in the first place was for marketing: you're supposed to get excited for the new version 6.0 or whatever and run down to the computer store and buy it to replace your old, outdated version 5.0. That model doesn't make sense for software that's free, though. Incremental updates make more sense. Features get rolled out gradually instead of being all bundled together for a big, splashy upgrade.
