Awesome 3.5 was released on 21 December when the Mayans (unsuccessfully) predicted the end of the world, so the release announcement is themed accordingly. This was also the same day as the Enlightenment E17 release.
The release of Awesome 3.5 comes more than three years after the release of Awesome 3.4. This window manager tries to be extremely extensible and configurable while being small and fast.
