The format is based on Keep a Changelog.

0.10.1 (December 31st, 2019)

Fixed

• Fix issue with concurrent connection acquiry. (Pull #700)
• Fix write error on closing HTTP/2 connections. (Pull #699)

0.10.0 (December 29th, 2019)

The 0.10.0 release makes some changes that will allow us to support both sync and async interfaces.

In particular with streaming responses the response.read() method becomes response.aread(), and the response.close() method becomes response.aclose().

If following redirects explicitly the response.next() method becomes response.anext().

Fixed

• End HTTP/2 streams immediately on no-body requests, rather than sending an empty body message. (Pull #682)
• Improve typing for Response.request: switch from Optional[Request] to Request. (Pull #666)
• Response.elapsed now reflects the entire download time. (Pull #687, #692)

Changed

• Added AsyncClient as a synonym for Client. (Pull #680)
• Switch to response.aread() for conditionally reading streaming responses. (Pull #674)
• Switch to response.aclose() and client.aclose() for explicit closing. (Pull #674, #675)
• Switch to response.anext() for resolving the next redirect response. (Pull #676)

Removed

• When using a client instance, the per-request usage of verify, cert, and trust_env have now escalated from raising a warning to raising an error. You should set these arguments on the client instead. (Pull #617)
• Removed the undocumented request.read(), since end users should not require it.

0.9.5 (December 20th, 2019)

Fixed

• Fix Host header and HSTS rewrites when an explicit :80 port is included in URL. (Pull #649)
• Query Params on the URL string are merged with any params=... argument. (Pull #653)
• More robust behavior when closing connections. (Pull #640)
• More robust behavior when handling HTTP/2 headers with trailing whitespace. (Pull #637)
• Allow any explicit Content-Type header to take precedence over the encoding default. (Pull #633)

0.9.4 (December 12th, 2019)

Fixed

• Added expiry to Keep-Alive connections, resolving issues with acquiring connections. (Pull #627)
• Increased flow control windows on HTTP/2, resolving download speed issues. (Pull #629)

0.9.3 (December 7th, 2019)

Fixed

• Fixed HTTP/2 with autodetection backend. (Pull #614)

0.9.2 (December 7th, 2019)

• Released due to packaging build artifact.

0.9.1 (December 6th, 2019)

• Released due to packaging build artifact.

0.9.0 (December 6th, 2019)

The 0.9 releases brings some major new features, including:

• A new streaming API.
• Autodetection of either asyncio or trio.
• Nicer timeout configuration.
• HTTP/2 support off by default, but can be enabled.

We've also removed all private types from the top-level package export.

In order to ensure you are only ever working with public API you should make sure to only import the top-level package eg. import httpx, rather than importing modules within the package.

Added

• Added concurrency backend autodetection. (Pull #585)
• Added Client(backend='trio') and Client(backend='asyncio') API. (Pull #585)
• Added response.stream_lines() API. (Pull #575)
• Added response.is_error API. (Pull #574)
• Added support for timeout=Timeout(5.0, connect_timeout=60.0) styles. (Pull #593)

Fixed

• Requests or Clients with timeout=None now correctly always disable timeouts. (Pull #592)
• Request 'Authorization' headers now have priority over .netrc authentication info. (Commit 095b691)
• Files without a filename no longer set a Content-Type in multipart data. (Commit ed94950)

Changed

• Added httpx.stream() API. Using stream=True now results in a warning. (Pull #600, #610)
• HTTP/2 support is switched to "off by default", but can be enabled explicitly. (Pull #584)
• Switched to Client(http2=True) API from Client(http_versions=["HTTP/1.1", "HTTP/2"]). (Pull #586)
• Removed all private types from the top-level package export. (Pull #608)
• The SSL configuration settings of verify, cert, and trust_env now raise warnings if used per-request when using a Client instance. They should always be set on the Client instance itself. (Pull #597)
• Use plain strings "TUNNEL_ONLY" or "FORWARD_ONLY" on the HTTPProxy proxy_mode argument. The HTTPProxyMode enum still exists, but its usage will raise warnings. (#610)
• Pool timeouts are now on the timeout configuration, not the pool limits configuration. (Pull #563)
• The timeout configuration is now named httpx.Timeout(...), not httpx.TimeoutConfig(...). The old version currently remains as a synonym for backwards compatability. (Pull #591)

0.8.0 (November 27, 2019)

Removed

Fixed

Removed

• The .delete() function no longer has json, data, or files parameters to match the expected semantics of the DELETE method. (Pull #408)
