Just FYI, more than one year has passed since the last release. The commit frequency has declined significantly. I use it, but I am not sure if I would recommend it in its current state. It does it's job and I like it, but the future is uncertain.
Also if you look at the dev branch [2], they have been making sweeping changes to the codebase; most recently it appears they have been removing "old" JavaScript libraries like Bower, presumably to move everything to an NPM setup.
