WebAssembly is tentatively spec'ed to require the application/wasm mime type for download sources:

The mimetype module should associate .wasm with this mimetype to allow users of SimpleHTTPServer etc. to be able to easily use WebAssembly.

We generally wait for something a bit stronger than "tentatively" before adding a mime type (ie: an actual submission to the relevant standards channel).

Tentative might be an understatement.
There was 4 browser sign-off on using that mime type within the WebAssembly CG, which has drafted the spec so far.
We're in the process of handing v1 of the spec off to the WebAssembly Working Group on our way to a good and proper W3C REC.
However, use of the mime type is already shipping in Chrome and I believe on the way with other browsers (and just got added to our shared toolchain).

That said we should get a proper allocation with IANA.
I've added an agenda item to our next Working Group meeting to have the group explicitly empower me to approach IANA:

Be back in month with a IANA request email to reference.

Assuming we've sorted out a proper allocation, do you have a sense of if getting the file type into python2.7 is likely?

Yes, updates of the mimetype database usually are backported to 2.7.

Yes, if/when it goes in it will go in to all currently maintained versions.  I've adjusted 'versions' accordingly.

We have a provisional registration for application/wasm now with IANA:

This is also shipping in Firefox and Chrome.

Would it be possible to merge this?

We're also depending on this MIME type for WebAssembly. It will be great if we can get this wasm MIME type in.

Seems this was fixed with . Thanks @flagxor for details in . I would propose closing this as fixed since issue34758 has PR merged and backport requests to other versions could possibly reopen issue34758?
