Same as 6.5.0 with one change:

Config::max_connections_per_host() is now properly named Config::set_max_connections_per_host().

Added

• Config has been stabilized and is now available by default!
• wasm_client support for Config (only timeouts).
• Config::max_connections_per_host (Supported on h1_client and curl_client.)

Deprecated

• H1Client::with_max_connections() will be superseded by Config::max_connections_per_host.

(Yanked)

Added

• Config has been stabilized and is now available by default!
• wasm_client support for Config (only timeouts).
• Config::max_connections_per_host (Supported on h1_client and curl_client.)

Deprecated

• H1Client::with_max_connections() will be superseded by Config::max_connections_per_host.

Docs

• Added "unstable-config" to the docs builds.

Added

• Added a new unstable-config feature, which exposes runtime configuration via a new Config struct.

Fixed

• Multiple headers of the same name are now present with any client backend and not just h1_client.
• Connection when multiple IPs are present for a hostname not function with the h1_client backend.

Fixed

• h1_client connection pools now properly check if connections are still alive before recycling them.
  • Like, actually properly this time.
  • There is a test now to ensure closed connections don't cause errors.

Fixed

• h1_client connection pools now properly check if connections are still alive before recycling them.

(This was the same thing as 6.3.1 released by git accident.)

Fixed

• Allow http-client to build & run properly when h1_client is enabled without either tls option.
• Prefer rustls if both tls features are enabled.

Internal

• More exhaustive CI for feature combinations.

Added

• Connection pooling (HTTP/1.1 keep-alive) for h1_client (default).
• native-tls (default) and rustls feature flags.
  • Only works with h1_client.
• Isahc metrics as a response extension for curl_client.

Fixed

• Box<dyn HttpClient> no longer infinitely recurses.
• curl_client now always correctly reads the response body.
• hyper_client should now build correctly.
• WasmClient fetch from worker scope now works correctly.

Internal

• Improved CI

This release implements HttpClient for Box<dyn HttpClient>.

Added

• impl HttpClient for Box<dyn HttpClient>

This release brings improvements for HyperClient (hyper_client feature).

Added

• HyperClient now impls Default.
• HyperClient::from_client(hyper::Client<C>).

Changed

• HyperClient now re-uses the internal client, allowing connection pooling.

This release moves the responsibility of any client sharing to the user.

Changed

• HttpClient implementations no longer impl Clone.
  • The responsibility for sharing is the user's.
• H1Client can no longer be instatiated via H1Client {}.
  • ::new() should be used.

Fixed

• Fixed a body stream translation bug in the hyper_client.

This release includes an optional backend using hyper.rs, and uses async-trait for HttpClient.

Added

• hyper_client feature, for using hyper.rs as the client backend.

Changed

• HttpClient now uses async-trait.
  • This attribute is also re-exported as http_client::async_trait.

Fixed

• Fixed WASM compilation.
• Fixed Isahc (curl) client translation setting duplicate headers incorrectly.

This release allows HttpClient to be used as a dynamic Trait object.

• HttpClient: removed Clone bounds.
• HttpClient: removed Error type.

This patch updates http-client to http-types 2.0.0 and a new version of async-h1.

Changes

• http types and async-h1 for 2.0.0 #27

Added

• Added a new backend: h1-client https://github.com/http-rs/http-client/pull/22

Changed

• All types are now based from hyperium/http to http-types https://github.com/http-rs/http-client/pull/22
