+# Change Log
+
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
+and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html).
+
+
+## [Unreleased]
+
+## [2.3.0] - 2022-02-21
+
+### Changed
+
+- Enabled the `$onRejected` callback of `HttpRejectedPromise` to return a promise for implementing a retry
+  mechanism [#168](https://github.com/php-http/httplug/pull/168)

+
+## [2.0.0] - 2018-10-31
+
+This version is no BC break for consumers using HTTPlug. However, HTTP clients that
+implement HTTPlug need to adjust because we add return type declarations.
+
+### Added
+
+- Support for PSR-18 (HTTP client).
+
+### Changed
+
+- **BC Break:** `HttpClient::sendRequest(RequestInterface $request)` has a return type annotation. The new
+signature is `HttpClient::sendRequest(RequestInterface $request): ResponseInterface`.

+signature is `RequestException::getRequest(): RequestInterface`.
+
+### Removed
+

+### Changed
+
+- Exception concept
+
+
+## [1.0.0-alpha3] - 2015-12-13
+
+### Changed
+
+- Async client does not throw exceptions
+
+### Removed
+
+- Promise interface moved to its own repository: [php-http/promise](https://github.com/php-http/promise)
+
+
+## [1.0.0-alpha2] - 2015-11-16
+
+### Added
+
+- Async client and Promise interface
+
+
+## [1.0.0-alpha] - 2015-10-26
+
+### Added
+
+- Better domain exceptions.
+
+### Changed
+
+- Purpose of the library: general HTTP CLient abstraction.
+
+### Removed
+
+- Request options: they should be configured at construction time.
+- Multiple request sending: should be done asynchronously using Async Client.
+- `getName` method
+
+
+## 0.1.0 - 2015-06-03
+
+### Added
+
+- Initial release

+
+**HTTPlug, the HTTP client abstraction for PHP.**
+
+
+## Intro
+
+HTTP client standard built on [PSR-7](http://www.php-fig.org/psr/psr-7/) HTTP
+messages. The HTTPlug client interface is compatible with the official standard
+for the HTTP client interface, [PSR-18](http://www.php-fig.org/psr/psr-18/).
+HTTPlug adds an interface for asynchronous HTTP requests, which PSR-18 does not
+cover.
+
+Since HTTPlug has already been widely adopted and a whole ecosystem has been
+built around it, we will keep maintaining this package for the time being.
+HTTPlug 2.0 and newer extend the PSR-18 interface to allow for a convenient
+migration path.
+
+New client implementations and consumers should use the PSR-18 interfaces
+directly. In the long term, we expect PSR-18 to completely replace the need
+for HTTPlug.
+
+
+## History
+
+HTTPlug is the official successor of the [ivory http adapter](https://github.com/egeloen/ivory-http-adapter).
+HTTPlug is a predecessor of [PSR-18](http://www.php-fig.org/psr/psr-18/)
