Version 0.11.1

0.11.1 (September 28nd, 2020)

Fixed

• Add await to async semaphore release() coroutine (#197)
• Drop incorrect curio classifier (#192)

Version 0.11.0

0.11.0 (September 22nd, 2020)

The Transport API with 0.11.0 has a couple of significant changes.

Firstly we've moved changed the request interface in order to allow extensions, which will later enable us to support features
such as trailing headers, HTTP/2 server push, and CONNECT/Upgrade connections.

The interface changes from:

def request(method, url, headers, stream, timeout):
    return (http_version, status_code, reason, headers, stream)

To instead including an optional dictionary of extensions on the request and response:

def request(method, url, headers, stream, ext):
    return (status_code, headers, stream, ext)

Having an open-ended extensions point will allow us to add later support for various optional features, that wouldn't otherwise be supported without these API changes.

In particular:

• Trailing headers support.
• HTTP/2 Server Push
• sendfile.
• Exposing raw connection on CONNECT, Upgrade, HTTP/2 bi-di streaming.
• Exposing debug information out of the API, including template name, template context.

Currently extensions are limited to:

• request: timeout - Optional. Timeout dictionary.
• response: http_version - Optional. Include the HTTP version used on the response.
• response: reason - Optional. Include the reason phrase used on the response. Only valid with HTTP/1.*.

See https://github.com/encode/httpx/issues/1274#issuecomment-694884553 for the history behind this.

Secondly, the async version of request is now namespaced as arequest.

This allows concrete transports to support both sync and async implementations on the same class.

Added

• Add curio support. (Pull #168)
• Add anyio support, with backend="anyio". (Pull #169)

Changed

• Update the Transport API to use 'ext' for optional extensions. (Pull #190)
• Update the Transport API to use .request and .arequest so implementations can support both sync and async. (Pull #189)

Fixed

• Always include the port on proxy CONNECT requests. (Pull #154)
• Fix max_keepalive_connections configuration. (Pull #153)

Version 0.10.1

0.10.1 (August 7th, 2020)

• Include max_keepalive_connections on AsyncHTTPProxy/SyncHTTPProxy classes.

Version 0.10.0

0.10.0 (August 7th, 2020)

The most notable change in the 0.10.0 release is that HTTP/2 support is now fully optional.

Added

• HTTP/2 support becomes optional. (Pull #121, #130)
• Add local_address=... support. (Pull #100, #134)
• Add PlainByteStream, IteratorByteStream, AsyncIteratorByteStream. The AsyncByteSteam and SyncByteStream classes are now pure interface classes. (#133)
• Add LocalProtocolError, RemoteProtocolError exceptions. (Pull #129)
• Add UnsupportedProtocol exception. (Pull #128)
• Add .get_connection_info() method. (Pull #102, #137)
• Add better TRACE logs. (Pull #101)

Changed

• max_keepalive is deprecated in favour of max_keepalive_connections. (Pull #140)

Fixed

• Improve handling of server disconnects. (Pull #112)
