py-httpx: updated to 0.15.4

0.15.4

Added
* Support direct comparisons between `Headers` and dicts or lists of two-tuples. \ 
Eg. `assert response.headers == {"Content-Length": 24}`

Fixed
* Fix automatic `.read()` when `Response` instances are created with \ 
`content=<str>`

0.15.3

Fixed
* Fixed connection leak in async client due to improper closing of response streams.

0.15.2

Fixed
* Fixed `response.elapsed` property.
* Fixed client authentication interaction with `.stream()`.

0.15.1

Fixed
* ASGITransport now properly applies URL decoding to the `path` component, \ 
as-per the ASGI spec.

0.15.0

Added
* Added support for curio. (Pull https://github.com/encode/httpcore/pull/168)
* Added support for event hooks.
* Added support for authentication flows which require either sync or async I/O.
* Added support for monitoring download progress with \ 
`response.num_bytes_downloaded`.
* Added `Request(content=...)` for byte content, instead of overloading \ 
`Request(data=...)`
* Added support for all URL components as parameter names when using \ 
`url.copy_with(...)`.
* Neater split between automatically populated headers on `Request` instances, \ 
vs default `client.headers`.
* Unclosed `AsyncClient` instances will now raise warnings if garbage collected.
* Support `Response(content=..., text=..., html=..., json=...)` for creating \ 
usable response instances in code.
* Support instantiating requests from the low-level transport API.
* Raise errors on invalid URL types.

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

Fixed
* Swapped ordering of redirects and authentication flow.
* `.netrc` lookups should use host, not host+port.

Removed
* The `URLLib3Transport` class no longer exists. We've published it instead as \ 
an example of [a custom transport \ 
class](https://gist.github.com/florimondmanca/d56764d78d748eb9f73165da388e546e).
* Drop `request.timer` attribute, which was being used internally to set \ 
`response.elapsed`.
* Drop `response.decoder` attribute, which was being used internally.
* `Request.prepare()` is now a private method.
* The `Headers.getlist()` method had previously been deprecated in favour of \ 
`Headers.get_list()`. It is now fully removed.
* The `QueryParams.getlist()` method had previously been deprecated in favour of \ 
`QueryParams.get_list()`. It is now fully removed.
* The `URL.is_ssl` property had previously been deprecated in favour of \ 
`URL.scheme == "https"`. It is now fully removed.
* The `httpx.PoolLimits` class had previously been deprecated in favour of \ 
`httpx.Limits`. It is now fully removed.
* The `max_keepalive` setting had previously been deprecated in favour of the \ 
more explicit `max_keepalive_connections`. It is now fully removed.
* The verbose `httpx.Timeout(5.0, connect_timeout=60.0)` style had previously \ 
been deprecated in favour of `httpx.Timeout(5.0, connect=60.0)`. It is now fully \ 
removed.
* Support for instantiating a timeout config missing some defaults, such as \ 
`httpx.Timeout(connect=60.0)`, had previously been deprecated in favour of \ 
enforcing a more explicit style, such as `httpx.Timeout(5.0, connect=60.0)`. \ 
This is now strictly enforced.

0.14.3

Added
* `http.Response()` may now be instantiated without a `request=...` parameter. \ 
Useful for some unit testing cases.
* Add `103 Early Hints` and `425 Too Early` status codes.

Fixed
* `DigestAuth` now handles responses that include multiple 'WWW-Authenticate' \ 
headers.
* Call into transport `__enter__`/`__exit__` or `__aenter__`/`__aexit__` when \ 
client is used in a context manager style.

0.14.2

Added
* Support `client.get(..., auth=None)` to bypass the default authentication on a \ 
clients.
* Support `client.auth = ...` property setter.
* Support `httpx.get(..., proxies=...)` on top-level request functions.
* Display instances with nicer import styles. (Eg. <httpx.ReadTimeout ...>)
* Support `cookies=[(key, value)]` list-of-two-tuples style usage.

Fixed
* Ensure that automatically included headers on a request may be modified.
* Allow explicit `Content-Length` header on streaming requests.
* Handle URL quoted usernames and passwords properly.
* Use more consistent default for `HEAD` requests, setting `allow_redirects=True`.
* If a transport error occurs while streaming the response, raise an `httpx` \ 
exception, not the underlying `httpcore` exception.
* Include the underlying `httpcore` traceback, when transport exceptions occur.

0.14.1

Added
* The `httpx.URL(...)` class now raises `httpx.InvalidURL` on invalid URLs, \ 
rather than exposing the underlying `rfc3986` exception. If a redirect response \ 
includes an invalid 'Location' header, then a `RemoteProtocolError` exception is \ 
raised, which will be associated with the request that caused it.

Fixed
* Handling multiple `Set-Cookie` headers became broken in the 0.14.0 release, \ 
and is now resolved.

0.14.0

The 0.14 release includes a range of improvements to the public API, intended on \ 
preparing for our upcoming 1.0 release.

* Our HTTP/2 support is now fully optional. **You now need to use `pip install \ 
httpx[http2]` if you want to include the HTTP/2 dependancies.**
* Our HSTS support has now been removed. Rewriting URLs from `http` to `https` \ 
if the host is on the HSTS list can be beneficial in avoiding roundtrips to \ 
incorrectly formed URLs, but on balance we've decided to remove this feature, on \ 
the principle of least surprise. Most programmatic clients do not include HSTS \ 
support, and for now we're opting to remove our support for it.
* Our exception hierarchy has been overhauled. Most users will want to stick \ 
with their existing `httpx.HTTPError` usage, but we've got a clearer overall \ 
structure now. See https://www.python-httpx.org/exceptions/ for more details.

When upgrading you should be aware of the following public API changes. Note \ 
that deprecated usages will currently continue to function, but will issue \ 
warnings.

* You should now use `httpx.codes` consistently instead of `httpx.StatusCodes`.
* Usage of `httpx.Timeout()` should now always include an explicit default. Eg. \ 
`httpx.Timeout(None, pool=5.0)`.
* When using `httpx.Timeout()`, we now have more concisely named keyword \ 
arguments. Eg. `read=5.0`, instead of `read_timeout=5.0`.
* Use `httpx.Limits()` instead of `httpx.PoolLimits()`, and `limits=...` instead \ 
of `pool_limits=...`.
* The `httpx.Limits(max_keepalive=...)` argument is now deprecated in favour of \ 
a more explicit `httpx.Limits(max_keepalive_connections=...)`.
* Keys used with `Client(proxies={...})` should now be in the style of \ 
`{"http://": ...}`, rather than `{"http": ...}`.
* The multidict methods `Headers.getlist()` and `QueryParams.getlist()` are \ 
deprecated in favour of more consistent `.get_list()` variants.
* The `URL.is_ssl` property is deprecated in favour of `URL.scheme == \ 
"https"`.
* The `URL.join(relative_url=...)` method is now `URL.join(url=...)`. This \ 
change does not support warnings for the deprecated usage style.

One notable aspect of the 0.14.0 release is that it tightens up the public API \ 
for `httpx`, by ensuring that several internal attributes and methods have now \ 
become strictly private.

The following previously had nominally public names on the client, but were all \ 
undocumented and intended solely for internal usage. They are all now replaced \ 
with underscored names, and should not be relied on or accessed.

These changes should not affect users who have been working from the `httpx` \ 
documentation.

* `.merge_url()`, `.merge_headers()`, `.merge_cookies()`, `.merge_queryparams()`
* `.build_auth()`, `.build_redirect_request()`
* `.redirect_method()`, `.redirect_url()`, `.redirect_headers()`, \ 
`.redirect_stream()`
* `.send_handling_redirects()`, `.send_handling_auth()`, `.send_single_request()`
* `.init_transport()`, `.init_proxy_transport()`
* `.proxies`, `.transport`, `.netrc`, `.get_proxy_map()`

Some areas of API which were already on the deprecation path, and were raising \ 
warnings or errors in 0.13.x have now been escalated to being fully removed.

* Drop `ASGIDispatch`, `WSGIDispatch`, which have been replaced by \ 
`ASGITransport`, `WSGITransport`.
* Drop `dispatch=...`` on client, which has been replaced by `transport=...``
* Drop `soft_limit`, `hard_limit`, which have been replaced by `max_keepalive` \ 
and `max_connections`.
* Drop `Response.stream` and` `Response.raw`, which have been replaced by \ 
``.aiter_bytes` and `.aiter_raw`.
* Drop `proxies=<transport instance>` in favor of `proxies=httpx.Proxy(...)`.

Added
* Added dedicated exception class `httpx.HTTPStatusError` for \ 
`.raise_for_status()` exceptions.
* Added `httpx.create_ssl_context()` helper function.
* Support for proxy exlcusions like \ 
`proxies={"https://www.example.com": None}`.
* Support `QueryParams(None)` and `client.params = None`.

Changed
* Use `httpx.codes` consistently in favour of `httpx.StatusCodes` which is \ 
placed into deprecation.
* Usage of `httpx.Timeout()` should now always include an explicit default. Eg. \ 
`httpx.Timeout(None, pool=5.0)`.
* Switch to more concise `httpx.Timeout()` keyword arguments. Eg. `read=5.0`, \ 
instead of `read_timeout=5.0`.
* Use `httpx.Limits()` instead of `httpx.PoolLimits()`, and `limits=...` instead \ 
of `pool_limits=...`.
* Keys used with `Client(proxies={...})` should now be in the style of \ 
`{"http://": ...}`, rather than `{"http": ...}`.
* The multidict methods `Headers.getlist` and `QueryParams.getlist` are \ 
deprecated in favour of more consistent `.get_list()` variants.
* `URL.port` becomes `Optional[int]`. Now only returns a port if one is \ 
explicitly included in the URL string.
* The `URL(..., allow_relative=[bool])` parameter no longer exists. All URL \ 
instances may be relative.
* Drop unnecessary `url.full_path = ...` property setter.
* The `URL.join(relative_url=...)` method is now `URL.join(url=...)`.
* The `URL.is_ssl` property is deprecated in favour of `URL.scheme == \ 
"https"`.

Fixed
* Add missing `Response.next()` method.
* Ensure all exception classes are exposed as public API.
* Support multiple items with an identical field name in multipart encodings.
* Skip HSTS preloading on single-label domains.
* Fixes for `Response.iter_lines()`.
* Ignore permission errors when accessing `.netrc` files.
* Allow bare hostnames in `HTTP_PROXY` etc... environment variables.
* Settings `app=...` or `transport=...` bypasses any environment based proxy \ 
defaults.
* Fix handling of `.base_url` when a path component is included in the base URL.
