Modernizr

Modernizr works by testing for over 40 next-generation features and creating a JavaScript object (named Modernizr) that contains the results of these tests as boolean properties.

What is new in version v2.6.2:

What is new in version v2.6:

• Geolocation used to be a trivial detect but two issues have come up recently that make it trickier.
• Opera fixed a bug affecting the <input type=color> detect, so we've sped up and simplified our detect.
• The ESR release of Firefox exposes MozWebsocket whereas every other supporting browser uses the standard WebSocket. We've quickened and simplified our detect accordingly.
• Plenty more inline documentation added about detection weirdness.
