Version 0.17.0

[lovelydinosaur]

Preliminary bit of drawing up 0.17.0 change log.

• httpx.HTTPTransport() - Add HTTPTransport and AsyncHTTPTransport #1399 (Need to make a call on how to fit in proxy support there too.)
• httpx.MockTransport() - Add httpx.MockTransport() #1401 (Once we've pulled in Add HTTPTransport and AsyncHTTPTransport #1399. For a nice consistency.)
• Update __version__.py and any notes in docs.

I'm somewhat minded to keep the httpx.json = ... (#1352) on the shelf a little longer.

Is there anything else pressing?

Looking all good on my side!

What's the status of a release? #1399 and #1401 have been merged, and now I'm itching to make use of HTTPTransport... :-)

[lovelydinosaur]

Looks like we'll also want #1465 in for this. Anything else?

@tomchristie I updated the changelog against 0.16.1...HEAD with the latest entries since this PR was opened. Also updated the version, and updated the docs to point to 0.17.*. :-) I think we're ready to release?

Woah this looks like a great release 🎉

[florimondmanca]

OK, let's roll with this. :-)
