If I were upgrade my older project (where I used Bootstrap 3) with Bootstrap 4, many things would break. I always thought that a good practice for a software is to be backwards compatible.

Another upsetting thing was that both Viv and I were looking at this page
https://v4-alpha.getbootstrap.com/layout/responsive-utilities/ and trying to figure out how to make it work. And only yesterday I noticed that at the top of the page it says "This is an outdated alpha release - please visit the latest Bootstrap 4 stable release." This banner is barely noticeable. Why not remove the page from the site at all?!
