This is some super fantastic news! Modernizr has been long respected as an invaluable feature detection toolkit for modern front end development. It’s made its way into such distributions as HTML5 Boilerplate and is part of many a front-ender’s personal framework (mine included).
Just this week, Modernizr 2 arrived. There are a bunch of great improvements, and perhaps one of the most elegant things to surface is the custom build tool that lets you feature detect only what you’re using on your site.
Definitely worth your time to check out.
