4.0.0 RC6

Note: This is a pre-release, there might be breaking changes in the final stable version.

• Connections are now attempted concurrently except for the first connection to a specific host if TLS is used, as that connection might be able to use HTTP/2
• Improved Response::setBody() API
• Improved backpressure mechanism for HTTP/2
• Changed Client and DefaultConnectionPool to be immutable, adding an interceptor returns a new instance now
• Client follows redirects by default, with an option to disable
• Client automatically retries unprocessed requests on properly closed HTTP/2 connections and idempotent requests on all connections up to two times now, the limit is customizable
• Added support for request attributes, a request local mutable storage for custom application / interceptor data
• Removed unused DnsException

4.0.0 RC5

Note: This is a pre-release, there might be breaking changes in the final stable version.

• Added compatibility for amphp/file@^1.
• Fixed cancelling an HTTP/1.x request while the request was being written.

4.0.0 RC4

Note: This is a pre-release, there might be breaking changes in the final stable version.

• Fixed appending query to path in HTTP/2 requests.

4.0.0 RC3

Note: This is a pre-release, there might be breaking changes in the final stable version.

• Added TimeoutInterceptor that automatically sets request timeouts when used in a Client interceptor stack (#188).
• HTTP/2 protocol is now declared as "2" instead of "2.0" in requests and responses (see https://http2.github.io/faq/#is-it-http20-or-http2).
• Pushed requests are no longer modified by interceptors extending ModifyRequest.
• Fixed cancellation of requests over HTTP/2.
• Fixed timeouts of requests over HTTP/2.
• Fixed remaining HTTP/2 stream calculations.

4.0.0 RC2

This release adds support for HTTP/2 push promises.

Note: This is a pre-release, there might be breaking changes in the final stable version.

Request now has an onPush() method which defines a callback invoked if the server pushes resources to the client. The callback should accept three arguments: Request $request, Promise $promise, and CancellationTokenSource $source. $request is the request as generated by the pushing server; $promise is a promise that is resolved with the Response object containing the pushed resource; and $source allows the push to be cancelled by the callback.

Request::getPushCallable() returns the callback defined with onPush().

If no push callback is defined in a request, the client automatically refuses any pushed resources.

Application and Network Interceptors should check for a push callback and apply transformations to the request and response accordingly.

Other changes or bugfixes

• Fixed writing HTTP/2 request bodies
• Fixed failed requests over HTTP/2 leaving promise returned from Client::request() unresolved
• Using pseudo headers (headers field names starting with a colon (:)) in a Request or Response object is now forbidden

4.0.0 RC1

Note: This is a pre-release, there might be breaking changes in the final stable version.

This is the first release candidate of amphp/http-client v4. Previously this package was named amphp/artax. Development of the v3.x release series will continue in the old amphp/artax repository.

Please test this pre-release carefully and report any issues you find, so we can soon tag a stable release with support for HTTP/2.

Major Changes

• Support for HTTP/2
• Support for ApplicationInterceptor / NetworkInterceptor
• Changed Request / Response to be mutable
• Compatibility with amphp/socket v1.0.0
• Client is now a final class instead of an interface
• Client behavior should now be modified using interceptors and connection pool implementations

3.0.14

• Fixed timeout token leak (#157)

3.0.13

• Bumped amphp/file to ^0.2 || ^0.3.

3.0.12

• Apply timeouts correctly during connection and TLS handshakes. Previously these could hang indefinitely. See #145.

3.0.11

• Fixed issues with responses without content-length and without transfer-encoding: chunked.
• Revert fix for v3.0.10, as this has been properly fixed in amphp/byte-stream.
• Catch ConnectException from amphp/socket and throw SocketException instead. The exception was previously leaked, but undocumented and unexpected.
