Added support for authentication flows which require either sync or async I/O. (Pull #1217)

Added Request(content=...) for byte content, instead of overloading Request(data=...) (Pull #1266)
Added support for all URL components as parameter names when using url.copy_with(...). (Pull #1285)
Neater split between automatically populated headers on Request instances, vs default client.headers. (Pull #1248)
Unclosed AsyncClient instances will now raise warnings if garbage collected. (Pull #1197)
Support Response(content=..., text=..., html=..., json=...) for creating usable response instances in code. (Pull #1265, #1297)
Support instantiating requests from the low-level transport API. (Pull #1293)
Raise errors on invalid URL types. (Pull #1259)

Cleaned up expected behaviour for URL escaping. url.path is now URL escaped. (Pull #1285)
Cleaned up expected behaviour for bytes vs str in URL components. url.userinfo and url.query are not URL escaped, and so return bytes. (Pull #1285)
Drop url.authority property in favour of url.netloc, since "authority" was semantically incorrect. (Pull #1285)
Drop url.full_path property in favour of url.raw_path, for better consistency with other parts of the API. (Pull #1285)
No longer use the chardet library for auto-detecting charsets, instead defaulting to a simpler approach when no charset is specified. (#1269)

The URLLib3Transport class no longer exists. We've published it instead as an example of a custom transport class. (Pull #1182)
Drop request.timer attribute, which was being used internally to set response.elapsed. (Pull #1249)
Drop response.decoder attribute, which was being used internally. (Pull #1276)
Request.prepare() is now a private method. (Pull #1284)
