I see support for woff2 in the Chromium source code but I don't see the mimetype registered with the IANA.

Think about the correct mime type for WOFF 2.0 files (Google uses font/woff2. W3C recommends application/font-woff2)

Am I missing something obvious or did this just not happen and people are implementing it?
