The 0.13.0.dev0 is a *pre-release* version. To install it, use `pip install httpx --pre`.
This release switches to `httpcore` for all the internal networking, which means:
* We're using the same codebase for both our sync and async clients.
* HTTP/2 support is now available with the sync client.
* We no longer have a `urllib3` dependency for our sync client, although there is still an *optional* `URLLib3Dispatcher` class.
It also means we've had to remove our UDS support, since maintaining that would have meant having to push back our work towards a 1.0 release, which isn't a trade-off we wanted to make.
