* Fixed a memory leak in the curl handlers in which references to callbacks

  were not being removed by `curl_reset`.

* Cookies are now extracted properly before redirects.

* Cookies now allow more character ranges.

* Decoded Content-Encoding responses are now modified to correctly reflect

  their state if the encoding was automatically removed by a handler. This

  means that the `Content-Encoding` header may be removed an the

  `Content-Length` modified to reflect the message size after removing the

  encoding.

* Added a more explicit error message when trying to use `form_params` and

  `multipart` in the same request.

* Several fixes for HHVM support.

* Functions are now conditionally required using an additional level of

  indirection to help with global Composer installations.

## 6.0.1 - 2015-05-27

* Fixed a bug with serializing the `query` request option where the `&`

  separator was missing.

* Added a better error message for when `body` is provided as an array. Please

  use `form_params` or `multipart` instead.

* Various doc fixes.

## 6.0.0 - 2015-05-26

* See the UPGRADING.md document for more information.

* Added `multipart` and `form_params` request options.

* Added `synchronous` request option.

* Added the `on_headers` request option.

* Fixed `expect` handling.

* No longer adding default middlewares in the client ctor. These need to be

  present on the provided handler in order to work.

* Requests are no longer initiated when sending async requests with the

  CurlMultiHandler. This prevents unexpected recursion from requests completing

  while ticking the cURL loop.

* Removed the semantics of setting `default` to `true`. This is no longer

  required now that the cURL loop is not ticked for async requests.

* Added request and response logging middleware.

* No longer allowing self signed certificates when using the StreamHandler.

* Ensuring that `sink` is valid if saving to a file.

* Request exceptions now include a "handler context" which provides handler

  specific contextual information.

* Added `GuzzleHttp\RequestOptions` to allow request options to be applied

  using constants.

* `$maxHandles` has been removed from CurlMultiHandler.

* `MultipartPostBody` is now part of the `guzzlehttp/psr7` package.

## 5.3.0 - 2015-05-19

* Mock now supports `save_to`

* Marked `AbstractRequestEvent::getTransaction()` as public.

* Fixed a bug in which multiple headers using different casing would overwrite

  previous headers in the associative array.

* Added `Utils::getDefaultHandler()`

* Marked `GuzzleHttp\Client::getDefaultUserAgent` as deprecated.

* URL scheme is now always lowercased.

## 6.0.0-beta.1

* Requires PHP >= 5.5

* Updated to use PSR-7

  * Requires immutable messages, which basically means an event based system

    owned by a request instance is no longer possible.

  * Utilizing the [Guzzle PSR-7 package](https://github.com/guzzle/psr7).

  * Removed the dependency on `guzzlehttp/streams`. These stream abstractions

    are available in the `guzzlehttp/psr7` package under the `GuzzleHttp\Psr7`

    namespace.

* Added middleware and handler system

  * Replaced the Guzzle event and subscriber system with a middleware system.

  * No longer depends on RingPHP, but rather places the HTTP handlers directly

    in Guzzle, operating on PSR-7 messages.

  * Retry logic is now encapsulated in `GuzzleHttp\Middleware::retry`, which

    means the `guzzlehttp/retry-subscriber` is now obsolete.

  * Mocking responses is now handled using `GuzzleHttp\Handler\MockHandler`.

* Asynchronous responses

  * No longer supports the `future` request option to send an async request.

    Instead, use one of the `*Async` methods of a client (e.g., `requestAsync`,

    `getAsync`, etc.).

  * Utilizing `GuzzleHttp\Promise` instead of React's promise library to avoid

    recursion required by chaining and forwarding react promises. See

    https://github.com/guzzle/promises

  * Added `requestAsync` and `sendAsync` to send request asynchronously.

  * Added magic methods for `getAsync()`, `postAsync()`, etc. to send requests

    asynchronously.

* Request options

  * POST and form updates

    * Added the `form_fields` and `form_files` request options.

    * Removed the `GuzzleHttp\Post` namespace.

    * The `body` request option no longer accepts an array for POST requests.

  * The `exceptions` request option has been deprecated in favor of the

    `http_errors` request options.

  * The `save_to` request option has been deprecated in favor of `sink` request

    option.

* Clients no longer accept an array of URI template string and variables for

  URI variables. You will need to expand URI templates before passing them

  into a client constructor or request method.

* Client methods `get()`, `post()`, `put()`, `patch()`, `options()`, etc. are

  now magic methods that will send synchronous requests.

* Replaced `Utils.php` with plain functions in `functions.php`.

* Removed `GuzzleHttp\Collection`.

* Removed `GuzzleHttp\BatchResults`. Batched pool results are now returned as

  an array.

* Removed `GuzzleHttp\Query`. Query string handling is now handled using an

  associative array passed into the `query` request option. The query string

  is serialized using PHP's `http_build_query`. If you need more control, you

  can pass the query string in as a string.

* `GuzzleHttp\QueryParser` has been replaced with the

  `GuzzleHttp\Psr7\parse_query`.

## 5.2.0 - 2015-01-27

* Added `AppliesHeadersInterface` to make applying headers to a request based

  on the body more generic and not specific to `PostBodyInterface`.

* Reduced the number of stack frames needed to send requests.

* Nested futures are now resolved in the client rather than the RequestFsm

* Finishing state transitions is now handled in the RequestFsm rather than the

  RingBridge.

* Added a guard in the Pool class to not use recursion for request retries.

## 5.1.0 - 2014-12-19

* Pool class no longer uses recursion when a request is intercepted.

* The size of a Pool can now be dynamically adjusted using a callback.

  See https://github.com/guzzle/guzzle/pull/943.

* Setting a request option to `null` when creating a request with a client will

  ensure that the option is not set. This allows you to overwrite default

  request options on a per-request basis.

  See https://github.com/guzzle/guzzle/pull/937.

* Added the ability to limit which protocols are allowed for redirects by

  specifying a `protocols` array in the `allow_redirects` request option.

* Nested futures due to retries are now resolved when waiting for synchronous

  responses. See https://github.com/guzzle/guzzle/pull/947.

* `"0"` is now an allowed URI path. See

  https://github.com/guzzle/guzzle/pull/935.

* `Query` no longer typehints on the `$query` argument in the constructor,

  allowing for strings and arrays.

* Exceptions thrown in the `end` event are now correctly wrapped with Guzzle

  specific exceptions if necessary.

## 5.0.3 - 2014-11-03

This change updates query strings so that they are treated as un-encoded values

by default where the value represents an un-encoded value to send over the

wire. A Query object then encodes the value before sending over the wire. This

means that even value query string values (e.g., ":") are url encoded. This

makes the Query class match PHP's http_build_query function. However, if you

want to send requests over the wire using valid query string characters that do

not need to be encoded, then you can provide a string to Url::setQuery() and

pass true as the second argument to specify that the query string is a raw

string that should not be parsed or encoded (unless a call to getQuery() is

subsequently made, forcing the query-string to be converted into a Query

object).

## 5.0.2 - 2014-10-30

* Added a trailing `\r\n` to multipart/form-data payloads. See

  https://github.com/guzzle/guzzle/pull/871

* Added a `GuzzleHttp\Pool::send()` convenience method to match the docs.

* Status codes are now returned as integers. See

  https://github.com/guzzle/guzzle/issues/881

* No longer overwriting an existing `application/x-www-form-urlencoded` header

  when sending POST requests, allowing for customized headers. See

  https://github.com/guzzle/guzzle/issues/877

* Improved path URL serialization.

  * No longer double percent-encoding characters in the path or query string if

    they are already encoded.

  * Now properly encoding the supplied path to a URL object, instead of only

    encoding ' ' and '?'.

  * Note: This has been changed in 5.0.3 to now encode query string values by

    default unless the `rawString` argument is provided when setting the query

    string on a URL: Now allowing many more characters to be present in the

    query string without being percent encoded. See https://tools.ietf.org/html/rfc3986#appendix-A

## 5.0.1 - 2014-10-16

Bugfix release.

* Fixed an issue where connection errors still returned response object in

  error and end events event though the response is unusable. This has been

  corrected so that a response is not returned in the `getResponse` method of

  these events if the response did not complete. https://github.com/guzzle/guzzle/issues/867

* Fixed an issue where transfer statistics were not being populated in the

  RingBridge. https://github.com/guzzle/guzzle/issues/866

## 5.0.0 - 2014-10-12

Adding support for non-blocking responses and some minor API cleanup.

### New Features

* Added support for non-blocking responses based on `guzzlehttp/guzzle-ring`.

* Added a public API for creating a default HTTP adapter.

* Updated the redirect plugin to be non-blocking so that redirects are sent

  concurrently. Other plugins like this can now be updated to be non-blocking.

* Added a "progress" event so that you can get upload and download progress

  events.

* Added `GuzzleHttp\Pool` which implements FutureInterface and transfers

  requests concurrently using a capped pool size as efficiently as possible.

* Added `hasListeners()` to EmitterInterface.

* Removed `GuzzleHttp\ClientInterface::sendAll` and marked

  `GuzzleHttp\Client::sendAll` as deprecated (it's still there, just not the

  recommended way).

### Breaking changes

The breaking changes in this release are relatively minor. The biggest thing to

look out for is that request and response objects no longer implement fluent

interfaces.

* Removed the fluent interfaces (i.e., `return $this`) from requests,

  responses, `GuzzleHttp\Collection`, `GuzzleHttp\Url`,

  `GuzzleHttp\Query`, `GuzzleHttp\Post\PostBody`, and

  `GuzzleHttp\Cookie\SetCookie`. This blog post provides a good outline of

  why I did this: https://ocramius.github.io/blog/fluent-interfaces-are-evil/.

  This also makes the Guzzle message interfaces compatible with the current

  PSR-7 message proposal.

* Removed "functions.php", so that Guzzle is truly PSR-4 compliant. Except

  for the HTTP request functions from function.php, these functions are now

  implemented in `GuzzleHttp\Utils` using camelCase. `GuzzleHttp\json_decode`

  moved to `GuzzleHttp\Utils::jsonDecode`. `GuzzleHttp\get_path` moved to

  `GuzzleHttp\Utils::getPath`. `GuzzleHttp\set_path` moved to

  `GuzzleHttp\Utils::setPath`. `GuzzleHttp\batch` should now be

  `GuzzleHttp\Pool::batch`, which returns an `objectStorage`. Using functions.php

  caused problems for many users: they aren't PSR-4 compliant, require an

  explicit include, and needed an if-guard to ensure that the functions are not

  declared multiple times.

* Rewrote adapter layer.

    * Removing all classes from `GuzzleHttp\Adapter`, these are now

      implemented as callables that are stored in `GuzzleHttp\Ring\Client`.

    * Removed the concept of "parallel adapters". Sending requests serially or

      concurrently is now handled using a single adapter.

    * Moved `GuzzleHttp\Adapter\Transaction` to `GuzzleHttp\Transaction`. The

      Transaction object now exposes the request, response, and client as public

      properties. The getters and setters have been removed.

* Removed the "headers" event. This event was only useful for changing the

  body a response once the headers of the response were known. You can implement

  a similar behavior in a number of ways. One example might be to use a

  FnStream that has access to the transaction being sent. For example, when the

  first byte is written, you could check if the response headers match your

  expectations, and if so, change the actual stream body that is being

  written to.

* Removed the `asArray` parameter from

  `GuzzleHttp\Message\MessageInterface::getHeader`. If you want to get a header

  value as an array, then use the newly added `getHeaderAsArray()` method of

  `MessageInterface`. This change makes the Guzzle interfaces compatible with

  the PSR-7 interfaces.

* `GuzzleHttp\Message\MessageFactory` no longer allows subclasses to add

  custom request options using double-dispatch (this was an implementation

  detail). Instead, you should now provide an associative array to the

  constructor which is a mapping of the request option name mapping to a

  function that applies the option value to a request.

* Removed the concept of "throwImmediately" from exceptions and error events.

  This control mechanism was used to stop a transfer of concurrent requests

  from completing. This can now be handled by throwing the exception or by

  cancelling a pool of requests or each outstanding future request individually.

* Updated to "GuzzleHttp\Streams" 3.0.

    * `GuzzleHttp\Stream\StreamInterface::getContents()` no longer accepts a

      `maxLen` parameter. This update makes the Guzzle streams project

      compatible with the current PSR-7 proposal.

    * `GuzzleHttp\Stream\Stream::__construct`,

      `GuzzleHttp\Stream\Stream::factory`, and

      `GuzzleHttp\Stream\Utils::create` no longer accept a size in the second

      argument. They now accept an associative array of options, including the

      "size" key and "metadata" key which can be used to provide custom metadata.

## 4.2.2 - 2014-09-08

* Fixed a memory leak in the CurlAdapter when reusing cURL handles.

* No longer using `request_fulluri` in stream adapter proxies.

* Relative redirects are now based on the last response, not the first response.

## 4.2.1 - 2014-08-19

* Ensuring that the StreamAdapter does not always add a Content-Type header

* Adding automated github releases with a phar and zip

## 4.2.0 - 2014-08-17

* Now merging in default options using a case-insensitive comparison.

  Closes https://github.com/guzzle/guzzle/issues/767

* Added the ability to automatically decode `Content-Encoding` response bodies

  using the `decode_content` request option. This is set to `true` by default

  to decode the response body if it comes over the wire with a

  `Content-Encoding`. Set this value to `false` to disable decoding the

  response content, and pass a string to provide a request `Accept-Encoding`

  header and turn on automatic response decoding. This feature now allows you

  to pass an `Accept-Encoding` header in the headers of a request but still

  disable automatic response decoding.

  Closes https://github.com/guzzle/guzzle/issues/764

* Added the ability to throw an exception immediately when transferring

  requests in parallel. Closes https://github.com/guzzle/guzzle/issues/760

* Updating guzzlehttp/streams dependency to ~2.1

* No longer utilizing the now deprecated namespaced methods from the stream

  package.

## 4.1.8 - 2014-08-14

* Fixed an issue in the CurlFactory that caused setting the `stream=false`

  request option to throw an exception.

  See: https://github.com/guzzle/guzzle/issues/769

* TransactionIterator now calls rewind on the inner iterator.

  See: https://github.com/guzzle/guzzle/pull/765

* You can now set the `Content-Type` header to `multipart/form-data`

  when creating POST requests to force multipart bodies.

  See https://github.com/guzzle/guzzle/issues/768

## 4.1.7 - 2014-08-07

* Fixed an error in the HistoryPlugin that caused the same request and response

  to be logged multiple times when an HTTP protocol error occurs.

* Ensuring that cURL does not add a default Content-Type when no Content-Type

  has been supplied by the user. This prevents the adapter layer from modifying

  the request that is sent over the wire after any listeners may have already

  put the request in a desired state (e.g., signed the request).

* Throwing an exception when you attempt to send requests that have the

  "stream" set to true in parallel using the MultiAdapter.

* Only calling curl_multi_select when there are active cURL handles. This was

  previously changed and caused performance problems on some systems due to PHP

  always selecting until the maximum select timeout.

* Fixed a bug where multipart/form-data POST fields were not correctly

  aggregated (e.g., values with "&").

## 4.1.6 - 2014-08-03

* Added helper methods to make it easier to represent messages as strings,

  including getting the start line and getting headers as a string.

## 4.1.5 - 2014-08-02

* Automatically retrying cURL "Connection died, retrying a fresh connect"

  errors when possible.

* cURL implementation cleanup

* Allowing multiple event subscriber listeners to be registered per event by

  passing an array of arrays of listener configuration.

## 4.1.4 - 2014-07-22

* Fixed a bug that caused multi-part POST requests with more than one field to

  serialize incorrectly.

* Paths can now be set to "0"

* `ResponseInterface::xml` now accepts a `libxml_options` option and added a

  missing default argument that was required when parsing XML response bodies.

* A `save_to` stream is now created lazily, which means that files are not

  created on disk unless a request succeeds.

## 4.1.3 - 2014-07-15

* Various fixes to multipart/form-data POST uploads

* Wrapping function.php in an if-statement to ensure Guzzle can be used

  globally and in a Composer install

* Fixed an issue with generating and merging in events to an event array

* POST headers are only applied before sending a request to allow you to change

  the query aggregator used before uploading

* Added much more robust query string parsing

* Fixed various parsing and normalization issues with URLs

* Fixing an issue where multi-valued headers were not being utilized correctly

  in the StreamAdapter

## 4.1.2 - 2014-06-18

* Added support for sending payloads with GET requests

## 4.1.1 - 2014-06-08

* Fixed an issue related to using custom message factory options in subclasses

* Added `ToArrayInterface` to `GuzzleHttp\Cookie\CookieJar`

## 4.1.0 - 2014-05-27

* Added a `json` request option to easily serialize JSON payloads.

* Added a `GuzzleHttp\json_decode()` wrapper to safely parse JSON.

* Added `setPort()` and `getPort()` to `GuzzleHttp\Message\RequestInterface`.

* Added the ability to provide an emitter to a client in the client constructor.

* Added the ability to persist a cookie session using $_SESSION.

* Added a trait that can be used to add event listeners to an iterator.

* Removed request method constants from RequestInterface.

* Fixed warning when invalid request start-lines are received.

* Updated MessageFactory to work with custom request option methods.

* Updated cacert bundle to latest build.

  associative array contains the "fn", "priority", and "once" keys.

## 4.0.0.rc-2 - 2014-03-25

* Removed `getConfig()` and `setConfig()` from clients to avoid confusion

  around whether things like base_url, message_factory, etc. should be able to

  be retrieved or modified.

* Curl classes now properly throw AdapterExceptions

* Various performance optimizations

* Streams are created with the faster `Stream\create()` function

* Marked deprecation_proxy() as internal

## 3.7.0 - 2013-06-10

* See UPGRADING.md for more information on how to upgrade.

* Requests now support the ability to specify an array of $options when creating a request to more easily modify a

  request. You can pass a 'request.options' configuration setting to a client to apply default request options to

  every request created by a client (e.g. default query string variables, headers, curl options, etc.).

* Added a static facade class that allows you to use Guzzle with static methods and mount the class to `\Guzzle`.

  See `Guzzle\Http\StaticClient::mount`.

* Added `command.request_options` to `Guzzle\Service\Command\AbstractCommand` to pass request options to requests

      created by a command (e.g. custom headers, query string variables, timeout settings, etc.).

* Stream size in `Guzzle\Stream\PhpStreamRequestFactory` will now be set if Content-Length is returned in the

  headers of a response

* Added `Guzzle\Common\Collection::setPath($path, $value)` to set a value into an array using a nested key

  (e.g. `$collection->setPath('foo/baz/bar', 'test'); echo $collection['foo']['bar']['bar'];`)

* ServiceBuilders now support storing and retrieving arbitrary data

* CachePlugin can now purge all resources for a given URI

* CachePlugin can automatically purge matching cached items when a non-idempotent request is sent to a resource

* Better handling of calculating the size of a stream in `Guzzle\Stream\Stream` using fstat() and caching the size

* `Guzzle\Common\Exception\ExceptionCollection` now creates a more readable exception message

* Fixing BC break: Added back the MonologLogAdapter implementation rather than extending from PsrLog so that older

  Symfony users can still use the old version of Monolog.

* Fixing BC break: Added the implementation back in for `Guzzle\Http\Message\AbstractMessage::getTokenizedHeader()`.

  Now triggering an E_USER_DEPRECATED warning when used. Use `$message->getHeader()->parseParams()`.

* Several performance improvements to `Guzzle\Common\Collection`

* Added an `$options` argument to the end of the following methods of `Guzzle\Http\ClientInterface`:

  createRequest, head, delete, put, patch, post, options, prepareRequest

* Added an `$options` argument to the end of `Guzzle\Http\Message\Request\RequestFactoryInterface::createRequest()`

* Added an `applyOptions()` method to `Guzzle\Http\Message\Request\RequestFactoryInterface`

* Changed `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $body = null)` to

  `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $options = array())`. You can still pass in a

  resource, string, or EntityBody into the $options parameter to specify the download location of the response.

* Changed `Guzzle\Common\Collection::__construct($data)` to no longer accepts a null value for `$data` but a

  default `array()`

* Added `Guzzle\Stream\StreamInterface::isRepeatable`

* Removed `Guzzle\Http\ClientInterface::setDefaultHeaders(). Use

  $client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`. or

  $client->getConfig()->setPath('request.options/headers', array('header_name' => 'value'))`.

* Removed `Guzzle\Http\Message\RequestInterface::setIsRedirect`

* Removed `Guzzle\Http\Message\RequestInterface::isRedirect`

* Made `Guzzle\Http\Client::expandTemplate` and `getUriTemplate` protected methods.

* You can now enable E_USER_DEPRECATED warnings to see if you are using a deprecated method by setting

  `Guzzle\Common\Version::$emitWarnings` to true.

* Marked `Guzzle\Http\Message\Request::isResponseBodyRepeatable()` as deprecated. Use

      `$request->getResponseBody()->isRepeatable()` instead.

* Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use

  `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.

* Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use

  `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.

* Marked `Guzzle\Http\Message\Request::setIsRedirect()` as deprecated. Use the HistoryPlugin instead.

* Marked `Guzzle\Http\Message\Request::isRedirect()` as deprecated. Use the HistoryPlugin instead.

* Marked `Guzzle\Cache\CacheAdapterFactory::factory()` as deprecated

* Marked `Guzzle\Service\Client::enableMagicMethods()` as deprecated. Magic methods can no longer be disabled on a Guzzle\Service\Client.

* Marked `Guzzle\Service\Client::getDefaultHeaders()` as deprecated. Use $client->getConfig()->getPath('request.options/headers')`.

* Marked `Guzzle\Service\Client::setDefaultHeaders()` as deprecated. Use $client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`.

* Marked `Guzzle\Parser\Url\UrlParser` as deprecated. Just use PHP's `parse_url()` and percent encode your UTF-8.

* Marked `Guzzle\Common\Collection::inject()` as deprecated.

* Marked `Guzzle\Plugin\CurlAuth\CurlAuthPlugin` as deprecated. Use `$client->getConfig()->setPath('request.options/auth', array('user', 'pass', 'Basic|Digest');`

* CacheKeyProviderInterface and DefaultCacheKeyProvider are no longer used. All of this logic is handled in a

  CacheStorageInterface. These two objects and interface will be removed in a future version.

* Always setting X-cache headers on cached responses

* Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin

* `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface

  $request, Response $response);`

* `CacheStorageInterface::fetch($key)` has changed to `fetch(RequestInterface $request);`

* `CacheStorageInterface::delete($key)` has changed to `delete(RequestInterface $request);`

* Added `CacheStorageInterface::purge($url)`

* `DefaultRevalidation::__construct(CacheKeyProviderInterface $cacheKey, CacheStorageInterface $cache, CachePlugin

  $plugin)` has changed to `DefaultRevalidation::__construct(CacheStorageInterface $cache,

  CanCacheStrategyInterface $canCache = null)`

* Added `RevalidationInterface::shouldRevalidate(RequestInterface $request, Response $response)`

## 3.6.0 - 2013-05-29

* ServiceDescription now implements ToArrayInterface

* Added command.hidden_params to blacklist certain headers from being treated as additionalParameters

* Guzzle can now correctly parse incomplete URLs

* Mixed casing of headers are now forced to be a single consistent casing across all values for that header.

* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution

* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader().

* Specific header implementations can be created for complex headers. When a message creates a header, it uses a

  HeaderFactory which can map specific headers to specific header classes. There is now a Link header and

  CacheControl header implementation.
