List of HTML 5 features unsupported by IE9
I'm trying to compile a list of HTML5 features NOT supported by IE9 (default installation, no manual additions):


     ■ WebGL (3D)
     ■ WebSockets
     ■ HTML5 Forms (validation mechanism, CSS3 selectors)
     ■ FormData
     ■ HTML5 multifile-upload
     ■ HTML5 video (only with certain file formats)
     ■ CSS3 Transitions (for animations)
     ■ CSS3 Text Shadow
     ■ CSS3 Gradients
     ■ CSS3 Border Image
     ■ CSS3 Flex box model
     ■ Application Cache (offline)
     ■ Web Workers (threads in JavaScript)
     ■ Drag’n Drop from Desktop
     ■ SMIL Animations (SVG animations)
     ■ File API
     ■ JavaScript Strict Mode
     ■ ForeignObject (embed external content in SVG)
     ■ ClassList APIs
     ■ HTML5 History API


 
And a list of stuff that IE9 can do that others don’t:

     ■ nothing so far



Did I miss anything ?
