# Change Log

## 2.1.0 - 2019-11-18

### Added

- Support Symfony 5

## 2.0.0 - 2019-02-03

### Changed
- HttpClientRouter now throws a HttpClientNoMatchException instead of a RequestException if it can not find a client for the request.
- RetryPlugin will only retry exceptions when there is no response, or a response in the 5xx HTTP code range.
- RetryPlugin also retries when no exception is thrown if the responses has HTTP code in the 5xx range.
  The callbacks for exception handling have been renamed and callbacks for response handling have been added.
- Abstract method `HttpClientPool::chooseHttpClient()` has now an explicit return type (`Http\Client\Common\HttpClientPoolItem`)
- Interface method `Plugin::handleRequest(...)` has now an explicit return type (`Http\Promise\Promise`)
- Made  classes final that are not intended to be extended.
- Added interfaces for BatchClient, HttpClientRouter and HttpMethodsClient.
  (These interfaces use the `Interface` suffix to avoid name collisions.)
- Added an interface for HttpClientPool and moved the abstract class to the HttpClientPool sub namespace.
- AddPathPlugin: Do not add the prefix if the URL already has the same prefix.
- All exceptions in `Http\Client\Common\Exception` are final.

### Removed
- Deprecated option `debug_plugins` has been removed from `PluginClient`
- Deprecated options `decider` and `delay` have been removed from `RetryPlugin`, use `exception_decider` and `exception_delay` instead.

## 1.9.1 - 2019-02-02

### Added

- Updated type hints in doc blocks.

## 1.9.0 - 2019-01-03

### Added

- Support for PSR-18 clients
- Added traits `VersionBridgePlugin` and `VersionBridgeClient` to help plugins and clients to support both
  1.x and 2.x version of `php-http/client-common` and `php-http/httplug`.

### Changed

- RetryPlugin: Renamed the configuration options for the exception retry callback from `decider` to `exception_decider`
  and `delay` to `exception_delay`. The old names still work but are deprecated.

## 1.8.2 - 2018-12-14

### Changed

- When multiple cookies exist, a single header with all cookies is sent as per RFC 6265 Section 5.4
- AddPathPlugin will now trim of ending slashes in paths

## 1.8.1 - 2018-10-09

### Fixed

- Reverted change to RetryPlugin so it again waits when retrying to avoid "can only throw objects" error.

## 1.8.0 - 2018-09-21

### Added

 - Add an option on ErrorPlugin to only throw exception on response with 5XX status code.

### Changed

- AddPathPlugin no longer add prefix multiple times if a request is restarted - it now only adds the prefix if that request chain has not yet passed through the AddPathPlugin

- `PluginClientFactory` to create `PluginClient` instances.
- Added new option 'delay' for `RetryPlugin`.
- Added new option 'decider' for `RetryPlugin`.
- Supports more cookie date formats in the Cookie Plugin

### Changed

- The `RetryPlugin` does now wait between retries. To disable/change this feature you must write something like: 
 
```php
$plugin = new RetryPlugin(['delay' => function(RequestInterface $request, Exception $e, $retries) { 
  return 0; 
}); 
```

### Deprecated

- The `debug_plugins` option for `PluginClient` is deprecated and will be removed in 2.0. Use the decorator design pattern instead like in [ProfilePlugin](https://github.com/php-http/HttplugBundle/blob/de33f9c14252f22093a5ec7d84f17535ab31a384/Collector/ProfilePlugin.php).
