Why is this at the top of HN right now? It's still in alpha. It's a good alpha and I've been using it on some projects, but I think some people might be mislead that this is the final release with the "4.0" in the title.

The most recent version is alpha 6, and it sounds like they are shooting for their first beta version next: http://blog.getbootstrap.com/2017/01/06/bootstrap-4-alpha-6/
