-## 6.0.2 - 2015-07-04
-
-* 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 http://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: http://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
-* Fixed an issue with nested form fields in a multi-part POST
-* Fixed an issue with using the `json` request option for POST requests
-* 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.

-  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()`.

-* 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.
-* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate
-* Removed from interface: Guzzle\Http\ClientInterface::setCurlMulti()
-* Removed Guzzle\Http\Message\Request::receivedRequestHeader() and implemented this functionality in

-  but are a no-op until removed.
-* Most classes that used to require a `Guzzle\Service\Command\CommandInterface` typehint now request a
-  `Guzzle\Service\Command\ArrayCommandInterface`.
-* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response
-  on a request while the request is still being transferred
-* The ability to case-insensitively search for header values
-* Guzzle\Http\Message\Header::hasExactHeader
-* Guzzle\Http\Message\Header::raw. Use getAll()

-* Deprecating Response::getRequest() and now using a shallow clone of a request object to remove a circular reference
-  to help with refcount based garbage collection of resources created by sending a request
-* Deprecating ZF1 cache and log adapters. These will be removed in the next major version.
-* Deprecating `Response::getPreviousResponse()` (method signature still exists, but it's deprecated). Use the
-  HistoryPlugin for a history.
-* Added a `responseBody` alias for the `response_body` location
-* Refactored internals to no longer rely on Response::getRequest()
-* HistoryPlugin can now be cast to a string
-* HistoryPlugin now logs transactions rather than requests and responses to more accurately keep track of the requests

-* The bundled SSL certificate is now provided in the phar file and extracted when running Guzzle from a phar.
-* You can now send any EntityEnclosingRequest with POST fields or POST files and cURL will handle creating bodies
-* POST requests using a custom entity body are now treated exactly like PUT requests but with a custom cURL method. This
-  means that the redirect behavior of POST requests with custom bodies will not be the same as POST requests that use

-* Lots of cleanup to CurlHandle::factory and RequestFactory::createRequest
-

-* BC: Setting a service description on a client will no longer modify the client's command factories.
-* BC: Emitting IO events from a RequestMediator is now a parameter that must be set in a request's curl options using
-  the 'emit_io' key. This was previously set under a request's parameters using 'curl.emit_io'

-  lowercase
-* Operation parameter objects are now lazy loaded internally

-    * Debug headers can now added to cached response in the CachePlugin
-
-## 3.2.0 - 2013-02-14
-
-* CurlMulti is no longer reused globally. A new multi object is created per-client. This helps to isolate clients.

-Guzzle, PHP HTTP client
-=======================
-
-[![Build Status](https://travis-ci.org/guzzle/guzzle.svg?branch=master)](https://travis-ci.org/guzzle/guzzle)
-
-Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and
-trivial to integrate with web services.
-
-- Simple interface for building query strings, POST requests, streaming large
-  uploads, streaming large downloads, using HTTP cookies, uploading JSON data,
-  etc...
-- Can send both synchronous and asynchronous requests using the same interface.
-- Uses PSR-7 interfaces for requests, responses, and streams. This allows you
-  to utilize other PSR-7 compatible libraries with Guzzle.
-- Abstracts away the underlying HTTP transport, allowing you to write
-  environment and transport agnostic code; i.e., no hard dependency on cURL,
-  PHP streams, sockets, or non-blocking event loops.
-- Middleware system allows you to augment and compose client behavior.
-
-```php
-$client = new \GuzzleHttp\Client();
-$res = $client->request('GET', 'https://api.github.com/user', [
-    'auth' => ['user', 'pass']
-]);
-echo $res->getStatusCode();
-// 200
-echo $res->getHeaderLine('content-type');
-// 'application/json; charset=utf8'
-echo $res->getBody();
-// {"type":"User"...'
-
-// Send an asynchronous request.
-$request = new \GuzzleHttp\Psr7\Request('GET', 'http://httpbin.org');
-$promise = $client->sendAsync($request)->then(function ($response) {
-    echo 'I completed! ' . $response->getBody();
-});
-$promise->wait();
-```

-## Installing Guzzle
-
-The recommended way to install Guzzle is through
-[Composer](http://getcomposer.org).
-
-```bash
-# Install Composer
-curl -sS https://getcomposer.org/installer | php
-```
-
-Next, run the Composer command to install the latest stable version of Guzzle:
-
-```bash
-php composer.phar require guzzlehttp/guzzle
-```
-
-After installing, you need to require Composer's autoloader:
-
-```php
-require 'vendor/autoload.php';
-```
-
-You can then later update Guzzle using composer:
-
- ```bash
-composer.phar update
- ```
-

-Guzzle Upgrade Guide
-====================
-
-5.0 to 6.0
-----------
-
-Guzzle now uses [PSR-7](http://www.php-fig.org/psr/psr-7/) for HTTP messages.
-Due to the fact that these messages are immutable, this prompted a refactoring
-of Guzzle to use a middleware based system rather than an event system. Any
-HTTP message interaction (e.g., `GuzzleHttp\Message\Request`) need to be
-updated to work with the new immutable PSR-7 request and response objects. Any
-event listeners or subscribers need to be updated to become middleware
-functions that wrap handlers (or are injected into a
-`GuzzleHttp\HandlerStack`).
-
-- Removed `GuzzleHttp\BatchResults`
-- Removed `GuzzleHttp\Collection`
-- Removed `GuzzleHttp\HasDataTrait`
-- Removed `GuzzleHttp\ToArrayInterface`
-- The `guzzlehttp/streams` dependency has been removed. Stream functionality
-  is now present in the `GuzzleHttp\Psr7` namespace provided by the
-  `guzzlehttp/psr7` package.
-- Guzzle no longer uses ReactPHP promises and now uses the
-  `guzzlehttp/promises` library. We use a custom promise library for three
-  significant reasons:
-  1. React promises (at the time of writing this) are recursive. Promise
-     chaining and promise resolution will eventually blow the stack. Guzzle
-     promises are not recursive as they use a sort of trampolining technique.
-     Note: there has been movement in the React project to modify promises to
-     no longer utilize recursion.
-  2. Guzzle needs to have the ability to synchronously block on a promise to
-     wait for a result. Guzzle promises allows this functionality (and does
-     not require the use of recursion).
-  3. Because we need to be able to wait on a result, doing so using React
-     promises requires wrapping react promises with RingPHP futures. This
-     overhead is no longer needed, reducing stack sizes, reducing complexity,
-     and improving performance.
-- `GuzzleHttp\Mimetypes` has been moved to a function in
-  `GuzzleHttp\Psr7\mimetype_from_extension` and
-  `GuzzleHttp\Psr7\mimetype_from_filename`.
-- `GuzzleHttp\Query` and `GuzzleHttp\QueryParser` have been removed. Query
-  strings must now be passed into request objects as strings, or provided to
-  the `query` request option when creating requests with clients. The `query`
-  option uses PHP's `http_build_query` to convert an array to a string. If you
-  need a different serialization technique, you will need to pass the query
-  string in as a string. There are a couple helper functions that will make
-  working with query strings easier: `GuzzleHttp\Psr7\parse_query` and
-  `GuzzleHttp\Psr7\build_query`.
-- Guzzle no longer has a dependency on RingPHP. Due to the use of a middleware
-  system based on PSR-7, using RingPHP and it's middleware system as well adds
-  more complexity than the benefits it provides. All HTTP handlers that were
-  present in RingPHP have been modified to work directly with PSR-7 messages
-  and placed in the `GuzzleHttp\Handler` namespace. This significantly reduces
-  complexity in Guzzle, removes a dependency, and improves performance. RingPHP
-  will be maintained for Guzzle 5 support, but will no longer be a part of
-  Guzzle 6.
-- As Guzzle now uses a middleware based systems the event system and RingPHP
-  integration has been removed. Note: while the event system has been removed,
-  it is possible to add your own type of event system that is powered by the
-  middleware system.
-  - Removed the `Event` namespace.
-  - Removed the `Subscriber` namespace.
-  - Removed `Transaction` class
-  - Removed `RequestFsm`
-  - Removed `RingBridge`
-  - `GuzzleHttp\Subscriber\Cookie` is now provided by
-    `GuzzleHttp\Middleware::cookies`
-  - `GuzzleHttp\Subscriber\HttpError` is now provided by
-    `GuzzleHttp\Middleware::httpError`
-  - `GuzzleHttp\Subscriber\History` is now provided by
-    `GuzzleHttp\Middleware::history`
-  - `GuzzleHttp\Subscriber\Mock` is now provided by
-    `GuzzleHttp\Handler\MockHandler`
-  - `GuzzleHttp\Subscriber\Prepare` is now provided by
-    `GuzzleHttp\PrepareBodyMiddleware`
-  - `GuzzleHttp\Subscriber\Redirect` is now provided by
-    `GuzzleHttp\RedirectMiddleware`
-- Guzzle now uses `Psr\Http\Message\UriInterface` (implements in
-  `GuzzleHttp\Psr7\Uri`) for URI support. `GuzzleHttp\Url` is now gone.
-- Static functions in `GuzzleHttp\Utils` have been moved to namespaced
-  functions under the `GuzzleHttp` namespace. This requires either a Composer
-  based autoloader or you to include functions.php.
-- `GuzzleHttp\ClientInterface::getDefaultOption` has been renamed to
-  `GuzzleHttp\ClientInterface::getConfig`.
-- `GuzzleHttp\ClientInterface::setDefaultOption` has been removed.
-- The `json` and `xml` methods of response objects has been removed. With the
-  migration to strictly adhering to PSR-7 as the interface for Guzzle messages,
-  adding methods to message interfaces would actually require Guzzle messages
-  to extend from PSR-7 messages rather then work with them directly.
-
-## Migrating to middleware
-
-The change to PSR-7 unfortunately required significant refactoring to Guzzle
-due to the fact that PSR-7 messages are immutable. Guzzle 5 relied on an event
-system from plugins. The event system relied on mutability of HTTP messages and
-side effects in order to work. With immutable messages, you have to change your
-workflow to become more about either returning a value (e.g., functional
-middlewares) or setting a value on an object. Guzzle v6 has chosen the
-functional middleware approach.
-
-Instead of using the event system to listen for things like the `before` event,
-you now create a stack based middleware function that intercepts a request on
-the way in and the promise of the response on the way out. This is a much
-simpler and more predictable approach than the event system and works nicely
-with PSR-7 middleware. Due to the use of promises, the middleware system is
-also asynchronous.
-
-v5:
-
-```php
-use GuzzleHttp\Event\BeforeEvent;
-$client = new GuzzleHttp\Client();
-// Get the emitter and listen to the before event.
-$client->getEmitter()->on('before', function (BeforeEvent $e) {
-    // Guzzle v5 events relied on mutation
-    $e->getRequest()->setHeader('X-Foo', 'Bar');
-});
-```
-
-v6:
-
-In v6, you can modify the request before it is sent using the `mapRequest`
-middleware. The idiomatic way in v6 to modify the request/response lifecycle is
-to setup a handler middleware stack up front and inject the handler into a
-client.
-
-```php
-use GuzzleHttp\Middleware;
-// Create a handler stack that has all of the default middlewares attached
-$handler = GuzzleHttp\HandlerStack::create();
-// Push the handler onto the handler stack
-$handler->push(Middleware::mapRequest(function (RequestInterface $request) {
-    // Notice that we have to return a request object
-    return $request->withHeader('X-Foo', 'Bar');
-}));
-// Inject the handler into the client
-$client = new GuzzleHttp\Client(['handler' => $handler]);
-```
-
-## POST Requests
-
-This version added the [`form_params`](http://guzzle.readthedocs.org/en/latest/request-options.html#form_params)
-and `multipart` request options. `form_params` is an associative array of
-strings or array of strings and is used to serialize an
-`application/x-www-form-urlencoded` POST request. The
-[`multipart`](http://guzzle.readthedocs.org/en/latest/request-options.html#multipart)
-option is now used to send a multipart/form-data POST request.
-
-`GuzzleHttp\Post\PostFile` has been removed. Use the `multipart` option to add
-POST files to a multipart/form-data request.
-
-The `body` option no longer accepts an array to send POST requests. Please use
-`multipart` or `form_params` instead.
-
-The `base_url` option has been renamed to `base_uri`.
-
-4.x to 5.0
-----------
-
-## Rewritten Adapter Layer
-
-Guzzle now uses [RingPHP](http://ringphp.readthedocs.org/en/latest) to send
-HTTP requests. The `adapter` option in a `GuzzleHttp\Client` constructor
-is still supported, but it has now been renamed to `handler`. Instead of
-passing a `GuzzleHttp\Adapter\AdapterInterface`, you must now pass a PHP
-`callable` that follows the RingPHP specification.
-
-## Removed Fluent Interfaces
-
-[Fluent interfaces were removed](http://ocramius.github.io/blog/fluent-interfaces-are-evil)
-from the following classes:
-
-- `GuzzleHttp\Collection`
-- `GuzzleHttp\Url`
-- `GuzzleHttp\Query`
-- `GuzzleHttp\Post\PostBody`
-- `GuzzleHttp\Cookie\SetCookie`
-
-## Removed functions.php
-
-Removed "functions.php", so that Guzzle is truly PSR-4 compliant. The following
-functions can be used as replacements.
-
-- `GuzzleHttp\json_decode` -> `GuzzleHttp\Utils::jsonDecode`
-- `GuzzleHttp\get_path` -> `GuzzleHttp\Utils::getPath`
-- `GuzzleHttp\Utils::setPath` -> `GuzzleHttp\set_path`
-- `GuzzleHttp\Pool::batch` -> `GuzzleHttp\batch`. This function is, however,
-  deprecated in favor of using `GuzzleHttp\Pool::batch()`.
-
-The "procedural" global client has been removed with no replacement (e.g.,
-`GuzzleHttp\get()`, `GuzzleHttp\post()`, etc.). Use a `GuzzleHttp\Client`
-object as a replacement.
-
-## `throwImmediately` has been removed
-
-The concept of "throwImmediately" has been removed 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.
-
-## headers event has 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.
-
-## Updates to HTTP Messages
-
-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.
-
-3.x to 4.0
-----------
-
-## Overarching changes:
-
-- Now requires PHP 5.4 or greater.
-- No longer requires cURL to send requests.
-- Guzzle no longer wraps every exception it throws. Only exceptions that are
-  recoverable are now wrapped by Guzzle.
-- Various namespaces have been removed or renamed.
-- No longer requiring the Symfony EventDispatcher. A custom event dispatcher
-  based on the Symfony EventDispatcher is
-  now utilized in `GuzzleHttp\Event\EmitterInterface` (resulting in significant
-  speed and functionality improvements).
-
-Changes per Guzzle 3.x namespace are described below.
-
-## Batch
-
-The `Guzzle\Batch` namespace has been removed. This is best left to
-third-parties to implement on top of Guzzle's core HTTP library.
-
-## Cache
-
-The `Guzzle\Cache` namespace has been removed. (Todo: No suitable replacement
-has been implemented yet, but hoping to utilize a PSR cache interface).
-
-## Common
-
-- Removed all of the wrapped exceptions. It's better to use the standard PHP
-  library for unrecoverable exceptions.
-- `FromConfigInterface` has been removed.
-- `Guzzle\Common\Version` has been removed. The VERSION constant can be found
-  at `GuzzleHttp\ClientInterface::VERSION`.
-
-### Collection
-
-- `getAll` has been removed. Use `toArray` to convert a collection to an array.
-- `inject` has been removed.
-- `keySearch` has been removed.
-- `getPath` no longer supports wildcard expressions. Use something better like
-  JMESPath for this.
-- `setPath` now supports appending to an existing array via the `[]` notation.
-
-### Events
-
-Guzzle no longer requires Symfony's EventDispatcher component. Guzzle now uses
-`GuzzleHttp\Event\Emitter`.
-
-- `Symfony\Component\EventDispatcher\EventDispatcherInterface` is replaced by
-  `GuzzleHttp\Event\EmitterInterface`.
-- `Symfony\Component\EventDispatcher\EventDispatcher` is replaced by
-  `GuzzleHttp\Event\Emitter`.
-- `Symfony\Component\EventDispatcher\Event` is replaced by
-  `GuzzleHttp\Event\Event`, and Guzzle now has an EventInterface in
-  `GuzzleHttp\Event\EventInterface`.
-- `AbstractHasDispatcher` has moved to a trait, `HasEmitterTrait`, and
-  `HasDispatcherInterface` has moved to `HasEmitterInterface`. Retrieving the
-  event emitter of a request, client, etc. now uses the `getEmitter` method
-  rather than the `getDispatcher` method.
-
-#### Emitter
-
-- Use the `once()` method to add a listener that automatically removes itself
-  the first time it is invoked.
-- Use the `listeners()` method to retrieve a list of event listeners rather than
-  the `getListeners()` method.
-- Use `emit()` instead of `dispatch()` to emit an event from an emitter.
-- Use `attach()` instead of `addSubscriber()` and `detach()` instead of
-  `removeSubscriber()`.
-
-```php
-$mock = new Mock();
-// 3.x
-$request->getEventDispatcher()->addSubscriber($mock);
-$request->getEventDispatcher()->removeSubscriber($mock);
-// 4.x
-$request->getEmitter()->attach($mock);
-$request->getEmitter()->detach($mock);
-```
-
-Use the `on()` method to add a listener rather than the `addListener()` method.
-
-```php
-// 3.x
-$request->getEventDispatcher()->addListener('foo', function (Event $event) { /* ... */ } );
-// 4.x
-$request->getEmitter()->on('foo', function (Event $event, $name) { /* ... */ } );
-```
-
-## Http
-
-### General changes
-
-- The cacert.pem certificate has been moved to `src/cacert.pem`.
-- Added the concept of adapters that are used to transfer requests over the
-  wire.
-- Simplified the event system.
-- Sending requests in parallel is still possible, but batching is no longer a
-  concept of the HTTP layer. Instead, you must use the `complete` and `error`
-  events to asynchronously manage parallel request transfers.
-- `Guzzle\Http\Url` has moved to `GuzzleHttp\Url`.
-- `Guzzle\Http\QueryString` has moved to `GuzzleHttp\Query`.
-- QueryAggregators have been rewritten so that they are simply callable
-  functions.
-- `GuzzleHttp\StaticClient` has been removed. Use the functions provided in
-  `functions.php` for an easy to use static client instance.
-- Exceptions in `GuzzleHttp\Exception` have been updated to all extend from
-  `GuzzleHttp\Exception\TransferException`.
-
-### Client
-
-Calling methods like `get()`, `post()`, `head()`, etc. no longer create and
-return a request, but rather creates a request, sends the request, and returns
-the response.
-
-```php
-// 3.0
-$request = $client->get('/');
-$response = $request->send();
-
-// 4.0
-$response = $client->get('/');
-
-// or, to mirror the previous behavior
-$request = $client->createRequest('GET', '/');
-$response = $client->send($request);
-```
-
-`GuzzleHttp\ClientInterface` has changed.
-
-- The `send` method no longer accepts more than one request. Use `sendAll` to
-  send multiple requests in parallel.
-- `setUserAgent()` has been removed. Use a default request option instead. You
-  could, for example, do something like:
-  `$client->setConfig('defaults/headers/User-Agent', 'Foo/Bar ' . $client::getDefaultUserAgent())`.
-- `setSslVerification()` has been removed. Use default request options instead,
-  like `$client->setConfig('defaults/verify', true)`.
-
-`GuzzleHttp\Client` has changed.
-
-- The constructor now accepts only an associative array. You can include a
-  `base_url` string or array to use a URI template as the base URL of a client.
-  You can also specify a `defaults` key that is an associative array of default
-  request options. You can pass an `adapter` to use a custom adapter,
-  `batch_adapter` to use a custom adapter for sending requests in parallel, or
-  a `message_factory` to change the factory used to create HTTP requests and
-  responses.
-- The client no longer emits a `client.create_request` event.
-- Creating requests with a client no longer automatically utilize a URI
-  template. You must pass an array into a creational method (e.g.,
-  `createRequest`, `get`, `put`, etc.) in order to expand a URI template.
-
-### Messages
-
-Messages no longer have references to their counterparts (i.e., a request no
-longer has a reference to it's response, and a response no loger has a
-reference to its request). This association is now managed through a
-`GuzzleHttp\Adapter\TransactionInterface` object. You can get references to
-these transaction objects using request events that are emitted over the
-lifecycle of a request.
-
-#### Requests with a body
-
-- `GuzzleHttp\Message\EntityEnclosingRequest` and
-  `GuzzleHttp\Message\EntityEnclosingRequestInterface` have been removed. The
-  separation between requests that contain a body and requests that do not
-  contain a body has been removed, and now `GuzzleHttp\Message\RequestInterface`
-  handles both use cases.
-- Any method that previously accepts a `GuzzleHttp\Response` object now accept a
-  `GuzzleHttp\Message\ResponseInterface`.
-- `GuzzleHttp\Message\RequestFactoryInterface` has been renamed to
-  `GuzzleHttp\Message\MessageFactoryInterface`. This interface is used to create
-  both requests and responses and is implemented in
-  `GuzzleHttp\Message\MessageFactory`.
-- POST field and file methods have been removed from the request object. You
-  must now use the methods made available to `GuzzleHttp\Post\PostBodyInterface`
-  to control the format of a POST body. Requests that are created using a
-  standard `GuzzleHttp\Message\MessageFactoryInterface` will automatically use
-  a `GuzzleHttp\Post\PostBody` body if the body was passed as an array or if
-  the method is POST and no body is provided.
-
-```php
-$request = $client->createRequest('POST', '/');
-$request->getBody()->setField('foo', 'bar');
-$request->getBody()->addFile(new PostFile('file_key', fopen('/path/to/content', 'r')));
-```
-
-#### Headers
-
-- `GuzzleHttp\Message\Header` has been removed. Header values are now simply
-  represented by an array of values or as a string. Header values are returned
-  as a string by default when retrieving a header value from a message. You can
-  pass an optional argument of `true` to retrieve a header value as an array
-  of strings instead of a single concatenated string.
-- `GuzzleHttp\PostFile` and `GuzzleHttp\PostFileInterface` have been moved to
-  `GuzzleHttp\Post`. This interface has been simplified and now allows the
-  addition of arbitrary headers.
-- Custom headers like `GuzzleHttp\Message\Header\Link` have been removed. Most
-  of the custom headers are now handled separately in specific
-  subscribers/plugins, and `GuzzleHttp\Message\HeaderValues::parseParams()` has
-  been updated to properly handle headers that contain parameters (like the
-  `Link` header).
-
-#### Responses
-
-- `GuzzleHttp\Message\Response::getInfo()` and
-  `GuzzleHttp\Message\Response::setInfo()` have been removed. Use the event
-  system to retrieve this type of information.
-- `GuzzleHttp\Message\Response::getRawHeaders()` has been removed.
-- `GuzzleHttp\Message\Response::getMessage()` has been removed.
-- `GuzzleHttp\Message\Response::calculateAge()` and other cache specific
-  methods have moved to the CacheSubscriber.
-- Header specific helper functions like `getContentMd5()` have been removed.
-  Just use `getHeader('Content-MD5')` instead.
-- `GuzzleHttp\Message\Response::setRequest()` and
-  `GuzzleHttp\Message\Response::getRequest()` have been removed. Use the event
-  system to work with request and response objects as a transaction.
-- `GuzzleHttp\Message\Response::getRedirectCount()` has been removed. Use the
-  Redirect subscriber instead.
-- `GuzzleHttp\Message\Response::isSuccessful()` and other related methods have
-  been removed. Use `getStatusCode()` instead.
-
-#### Streaming responses
-
-Streaming requests can now be created by a client directly, returning a
-`GuzzleHttp\Message\ResponseInterface` object that contains a body stream
-referencing an open PHP HTTP stream.
-
-```php
-// 3.0
-use Guzzle\Stream\PhpStreamRequestFactory;
-$request = $client->get('/');
-$factory = new PhpStreamRequestFactory();
-$stream = $factory->fromRequest($request);
-$data = $stream->read(1024);
-
-// 4.0
-$response = $client->get('/', ['stream' => true]);
-// Read some data off of the stream in the response body
-$data = $response->getBody()->read(1024);
-```
-
-#### Redirects
-
-The `configureRedirects()` method has been removed in favor of a
-`allow_redirects` request option.
-
-```php
-// Standard redirects with a default of a max of 5 redirects
-$request = $client->createRequest('GET', '/', ['allow_redirects' => true]);
-
-// Strict redirects with a custom number of redirects
-$request = $client->createRequest('GET', '/', [
-    'allow_redirects' => ['max' => 5, 'strict' => true]
-]);
-```
-
-#### EntityBody
-
-EntityBody interfaces and classes have been removed or moved to
-`GuzzleHttp\Stream`. All classes and interfaces that once required
-`GuzzleHttp\EntityBodyInterface` now require
-`GuzzleHttp\Stream\StreamInterface`. Creating a new body for a request no
-longer uses `GuzzleHttp\EntityBody::factory` but now uses
-`GuzzleHttp\Stream\Stream::factory` or even better:
-`GuzzleHttp\Stream\create()`.
-
-- `Guzzle\Http\EntityBodyInterface` is now `GuzzleHttp\Stream\StreamInterface`
-- `Guzzle\Http\EntityBody` is now `GuzzleHttp\Stream\Stream`
-- `Guzzle\Http\CachingEntityBody` is now `GuzzleHttp\Stream\CachingStream`
-- `Guzzle\Http\ReadLimitEntityBody` is now `GuzzleHttp\Stream\LimitStream`
-- `Guzzle\Http\IoEmittyinEntityBody` has been removed.
-
-#### Request lifecycle events
-
-Requests previously submitted a large number of requests. The number of events
-emitted over the lifecycle of a request has been significantly reduced to make
-it easier to understand how to extend the behavior of a request. All events
-emitted during the lifecycle of a request now emit a custom
-`GuzzleHttp\Event\EventInterface` object that contains context providing
-methods and a way in which to modify the transaction at that specific point in
-time (e.g., intercept the request and set a response on the transaction).
-
-- `request.before_send` has been renamed to `before` and now emits a
-  `GuzzleHttp\Event\BeforeEvent`
-- `request.complete` has been renamed to `complete` and now emits a
-  `GuzzleHttp\Event\CompleteEvent`.
-- `request.sent` has been removed. Use `complete`.
-- `request.success` has been removed. Use `complete`.
-- `error` is now an event that emits a `GuzzleHttp\Event\ErrorEvent`.
-- `request.exception` has been removed. Use `error`.
-- `request.receive.status_line` has been removed.
-- `curl.callback.progress` has been removed. Use a custom `StreamInterface` to
-  maintain a status update.
-- `curl.callback.write` has been removed. Use a custom `StreamInterface` to
-  intercept writes.
-- `curl.callback.read` has been removed. Use a custom `StreamInterface` to
-  intercept reads.
-
-`headers` is a new event that is emitted after the response headers of a
-request have been received before the body of the response is downloaded. This
-event emits a `GuzzleHttp\Event\HeadersEvent`.
-
-You can intercept a request and inject a response using the `intercept()` event
-of a `GuzzleHttp\Event\BeforeEvent`, `GuzzleHttp\Event\CompleteEvent`, and
-`GuzzleHttp\Event\ErrorEvent` event.
-
-See: http://docs.guzzlephp.org/en/latest/events.html
-
-## Inflection
-
-The `Guzzle\Inflection` namespace has been removed. This is not a core concern
-of Guzzle.
-
-## Iterator
-
-The `Guzzle\Iterator` namespace has been removed.
-
-- `Guzzle\Iterator\AppendIterator`, `Guzzle\Iterator\ChunkedIterator`, and
-  `Guzzle\Iterator\MethodProxyIterator` are nice, but not a core requirement of
-  Guzzle itself.
-- `Guzzle\Iterator\FilterIterator` is no longer needed because an equivalent
-  class is shipped with PHP 5.4.
-- `Guzzle\Iterator\MapIterator` is not really needed when using PHP 5.5 because
-  it's easier to just wrap an iterator in a generator that maps values.
-
-For a replacement of these iterators, see https://github.com/nikic/iter
-
-## Log
-
-The LogPlugin has moved to https://github.com/guzzle/log-subscriber. The
-`Guzzle\Log` namespace has been removed. Guzzle now relies on
-`Psr\Log\LoggerInterface` for all logging. The MessageFormatter class has been
-moved to `GuzzleHttp\Subscriber\Log\Formatter`.
-
-## Parser
-
-The `Guzzle\Parser` namespace has been removed. This was previously used to
-make it possible to plug in custom parsers for cookies, messages, URI
-templates, and URLs; however, this level of complexity is not needed in Guzzle
-so it has been removed.
-
-- Cookie: Cookie parsing logic has been moved to
-  `GuzzleHttp\Cookie\SetCookie::fromString`.
-- Message: Message parsing logic for both requests and responses has been moved
-  to `GuzzleHttp\Message\MessageFactory::fromMessage`. Message parsing is only
-  used in debugging or deserializing messages, so it doesn't make sense for
-  Guzzle as a library to add this level of complexity to parsing messages.
-- UriTemplate: URI template parsing has been moved to
-  `GuzzleHttp\UriTemplate`. The Guzzle library will automatically use the PECL
-  URI template library if it is installed.
-- Url: URL parsing is now performed in `GuzzleHttp\Url::fromString` (previously
-  it was `Guzzle\Http\Url::factory()`). If custom URL parsing is necessary,
-  then developers are free to subclass `GuzzleHttp\Url`.
-
-## Plugin
-
-The `Guzzle\Plugin` namespace has been renamed to `GuzzleHttp\Subscriber`.
-Several plugins are shipping with the core Guzzle library under this namespace.
-
-- `GuzzleHttp\Subscriber\Cookie`: Replaces the old CookiePlugin. Cookie jar
-  code has moved to `GuzzleHttp\Cookie`.
-- `GuzzleHttp\Subscriber\History`: Replaces the old HistoryPlugin.
-- `GuzzleHttp\Subscriber\HttpError`: Throws errors when a bad HTTP response is
-  received.
-- `GuzzleHttp\Subscriber\Mock`: Replaces the old MockPlugin.
-- `GuzzleHttp\Subscriber\Prepare`: Prepares the body of a request just before
-  sending. This subscriber is attached to all requests by default.
-- `GuzzleHttp\Subscriber\Redirect`: Replaces the RedirectPlugin.
-
-The following plugins have been removed (third-parties are free to re-implement
-these if needed):
-
-- `GuzzleHttp\Plugin\Async` has been removed.
-- `GuzzleHttp\Plugin\CurlAuth` has been removed.
-- `GuzzleHttp\Plugin\ErrorResponse\ErrorResponsePlugin` has been removed. This
-  functionality should instead be implemented with event listeners that occur
-  after normal response parsing occurs in the guzzle/command package.
-
-The following plugins are not part of the core Guzzle package, but are provided
-in separate repositories:
-
-- `Guzzle\Http\Plugin\BackoffPlugin` has been rewritten to be much simpler
-  to build custom retry policies using simple functions rather than various
-  chained classes. See: https://github.com/guzzle/retry-subscriber
-- `Guzzle\Http\Plugin\Cache\CachePlugin` has moved to
-  https://github.com/guzzle/cache-subscriber
-- `Guzzle\Http\Plugin\Log\LogPlugin` has moved to
-  https://github.com/guzzle/log-subscriber
-- `Guzzle\Http\Plugin\Md5\Md5Plugin` has moved to
-  https://github.com/guzzle/message-integrity-subscriber
-- `Guzzle\Http\Plugin\Mock\MockPlugin` has moved to
-  `GuzzleHttp\Subscriber\MockSubscriber`.
-- `Guzzle\Http\Plugin\Oauth\OauthPlugin` has moved to
-  https://github.com/guzzle/oauth-subscriber
-
-## Service
-
-The service description layer of Guzzle has moved into two separate packages:
-
-- http://github.com/guzzle/command Provides a high level abstraction over web
-  services by representing web service operations using commands.
-- http://github.com/guzzle/guzzle-services Provides an implementation of
-  guzzle/command that provides request serialization and response parsing using
-  Guzzle service descriptions.
-
-## Stream
-
-Stream have moved to a separate package available at
-https://github.com/guzzle/streams.
-
-`Guzzle\Stream\StreamInterface` has been given a large update to cleanly take
-on the responsibilities of `Guzzle\Http\EntityBody` and
-`Guzzle\Http\EntityBodyInterface` now that they have been removed. The number
-of methods implemented by the `StreamInterface` has been drastically reduced to
-allow developers to more easily extend and decorate stream behavior.
-
-## Removed methods from StreamInterface
-
-- `getStream` and `setStream` have been removed to better encapsulate streams.
-- `getMetadata` and `setMetadata` have been removed in favor of
-  `GuzzleHttp\Stream\MetadataStreamInterface`.
-- `getWrapper`, `getWrapperData`, `getStreamType`, and `getUri` have all been
-  removed. This data is accessible when
-  using streams that implement `GuzzleHttp\Stream\MetadataStreamInterface`.
-- `rewind` has been removed. Use `seek(0)` for a similar behavior.
-
-## Renamed methods
-
-- `detachStream` has been renamed to `detach`.
-- `feof` has been renamed to `eof`.
-- `ftell` has been renamed to `tell`.
-- `readLine` has moved from an instance method to a static class method of
-  `GuzzleHttp\Stream\Stream`.
-
-## Metadata streams
-
-`GuzzleHttp\Stream\MetadataStreamInterface` has been added to denote streams
-that contain additional metadata accessible via `getMetadata()`.
-`GuzzleHttp\Stream\StreamInterface::getMetadata` and
-`GuzzleHttp\Stream\StreamInterface::setMetadata` have been removed.
-
-## StreamRequestFactory
-
-The entire concept of the StreamRequestFactory has been removed. The way this
-was used in Guzzle 3 broke the actual interface of sending streaming requests
-(instead of getting back a Response, you got a StreamInterface). Streaming
-PHP requests are now implemented through the `GuzzleHttp\Adapter\StreamAdapter`.
-
-3.6 to 3.7

-### Deprecations
-
-- You can now enable E_USER_DEPRECATED warnings to see if you are using any deprecated methods.:
-
-```php
-\Guzzle\Common\Version::$emitWarnings = true;
-```
-
-The following APIs and options have been marked as deprecated:
-
-- Marked `Guzzle\Http\Message\Request::isResponseBodyRepeatable()` as deprecated. Use `$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\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
-  `$client->getConfig()->setPath('request.options/auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));` or
-  `$client->setDefaultOption('auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));`
-
-3.7 introduces `request.options` as a parameter for a client configuration and as an optional argument to all creational
-request methods. When paired with a client's configuration settings, these options allow you to specify default settings
-for various aspects of a request. Because these options make other previous configuration options redundant, several
-configuration options and methods of a client and AbstractCommand have been deprecated.
-
-- Marked `Guzzle\Service\Client::getDefaultHeaders()` as deprecated. Use `$client->getDefaultOption('headers')`.
-- Marked `Guzzle\Service\Client::setDefaultHeaders()` as deprecated. Use `$client->setDefaultOption('headers/{header_name}', 'value')`.
-- Marked 'request.params' for `Guzzle\Http\Client` as deprecated. Use `$client->setDefaultOption('params/{param_name}', 'value')`
-- Marked 'command.headers', 'command.response_body' and 'command.on_complete' as deprecated for AbstractCommand. These will work through Guzzle 4.0
-
-        $command = $client->getCommand('foo', array(
-            'command.headers' => array('Test' => '123'),
-            'command.response_body' => '/path/to/file'
-        ));
-
-        // Should be changed to:
-
-        $command = $client->getCommand('foo', array(
-            'command.request_options' => array(
-                'headers' => array('Test' => '123'),
-                'save_as' => '/path/to/file'
-            )
-        ));
-
-### Interface changes
-
-Additions and changes (you will need to update any implementations or subclasses you may have created):
-
-- Added an `$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 `$data` but a
-  default `array()`
-- Added `Guzzle\Stream\StreamInterface::isRepeatable`
-- Made `Guzzle\Http\Client::expandTemplate` and `getUriTemplate` protected methods.
-
-The following methods were removed from interfaces. All of these methods are still available in the concrete classes
-that implement them, but you should update your code to use alternative methods:
-
-- Removed `Guzzle\Http\ClientInterface::setDefaultHeaders(). Use
-  `$client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`. or
-  `$client->getConfig()->setPath('request.options/headers', array('header_name' => 'value'))` or
-  `$client->setDefaultOption('headers/{header_name}', 'value')`. or
-  `$client->setDefaultOption('headers', array('header_name' => 'value'))`.
-- Removed `Guzzle\Http\ClientInterface::getDefaultHeaders(). Use `$client->getConfig()->getPath('request.options/headers')`.
-- Removed `Guzzle\Http\ClientInterface::expandTemplate()`. This is an implementation detail.
-- Removed `Guzzle\Http\ClientInterface::setRequestFactory()`. This is an implementation detail.
-- Removed `Guzzle\Http\ClientInterface::getCurlMulti()`. This is a very specific implementation detail.
-- Removed `Guzzle\Http\Message\RequestInterface::canCache`. Use the CachePlugin.
-- Removed `Guzzle\Http\Message\RequestInterface::setIsRedirect`. Use the HistoryPlugin.
-- Removed `Guzzle\Http\Message\RequestInterface::isRedirect`. Use the HistoryPlugin.
-
-### Cache plugin breaking changes
-
-- 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)`
-
-3.5 to 3.6
-----------
-
-* 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().
-  For example, setHeader() first removes the header using unset on a HeaderCollection and then calls addHeader().
-  Keeping the Host header and URL host in sync is now handled by overriding the addHeader method in Request.
-* 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.
-* Moved getLinks() from Response to just be used on a Link header object.
-
-If you previously relied on Guzzle\Http\Message\Header::raw(), then you will need to update your code to use the
-HeaderInterface (e.g. toArray(), getAll(), etc.).
-
-### Interface changes
-
-* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate
-* Removed from interface: Guzzle\Http\ClientInterface::setCurlMulti()
-* Removed Guzzle\Http\Message\Request::receivedRequestHeader() and implemented this functionality in
-  Guzzle\Http\Curl\RequestMediator
-* Removed the optional $asString parameter from MessageInterface::getHeader(). Just cast the header to a string.
-* Removed the optional $tryChunkedTransfer option from Guzzle\Http\Message\EntityEnclosingRequestInterface
-* Removed the $asObjects argument from Guzzle\Http\Message\MessageInterface::getHeaders()
-
-### Removed deprecated functions
-
-* Removed Guzzle\Parser\ParserRegister::get(). Use getParser()
-* Removed Guzzle\Parser\ParserRegister::set(). Use registerParser().
-
-### Deprecations
-
-* The ability to case-insensitively search for header values
-* Guzzle\Http\Message\Header::hasExactHeader
-* Guzzle\Http\Message\Header::raw. Use getAll()
-* Deprecated cache control specific methods on Guzzle\Http\Message\AbstractMessage. Use the CacheControl header object
-  instead.
-
-### Other changes
-
-* All response header helper functions return a string rather than mixing Header objects and strings inconsistently
-* Removed cURL blacklist support. This is no longer necessary now that Expect, Accept, etc. are managed by Guzzle
-  directly via interfaces
-* Removed the injecting of a request object onto a response object. The methods to get and set a request still exist
-  but are a no-op until removed.
-* Most classes that used to require a `Guzzle\Service\Command\CommandInterface` typehint now request a
-  `Guzzle\Service\Command\ArrayCommandInterface`.
-* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response
-  on a request while the request is still being transferred
-* `Guzzle\Service\Command\CommandInterface` now extends from ToArrayInterface and ArrayAccess
-
-3.3 to 3.4
-----------
-
-Base URLs of a client now follow the rules of http://tools.ietf.org/html/rfc3986#section-5.2.2 when merging URLs.
-
-3.2 to 3.3
-----------
-
-### Response::getEtag() quote stripping removed
-
-`Guzzle\Http\Message\Response::getEtag()` no longer strips quotes around the ETag response header
-
-### Removed `Guzzle\Http\Utils`
-
-The `Guzzle\Http\Utils` class was removed. This class was only used for testing.
-
-### Stream wrapper and type
-
-`Guzzle\Stream\Stream::getWrapper()` and `Guzzle\Stream\Stream::getStreamType()` are no longer converted to lowercase.
-
-### curl.emit_io became emit_io
-
-Emitting IO events from a RequestMediator is now a parameter that must be set in a request's curl options using the
-'emit_io' key. This was previously set under a request's parameters using 'curl.emit_io'
-
-3.1 to 3.2
-----------
-
-### CurlMulti is no longer reused globally
-
-Before 3.2, the same CurlMulti object was reused globally for each client. This can cause issue where plugins added
-to a single client can pollute requests dispatched from other clients.
-
-If you still wish to reuse the same CurlMulti object with each client, then you can add a listener to the
-ServiceBuilder's `service_builder.create_client` event to inject a custom CurlMulti object into each client as it is
-created.
-
-```php
-$multi = new Guzzle\Http\Curl\CurlMulti();
-$builder = Guzzle\Service\Builder\ServiceBuilder::factory('/path/to/config.json');
-$builder->addListener('service_builder.create_client', function ($event) use ($multi) {
-    $event['client']->setCurlMulti($multi);
-}
-});
-```
-
-### No default path
-
-URLs no longer have a default path value of '/' if no path was specified.
-
-Before:
-
-```php
-$request = $client->get('http://www.foo.com');
-echo $request->getUrl();
-// >> http://www.foo.com/
-```
-
-After:
-
-```php
-$request = $client->get('http://www.foo.com');
-echo $request->getUrl();
-// >> http://www.foo.com
-```
-
-### Less verbose BadResponseException
-
-The exception message for `Guzzle\Http\Exception\BadResponseException` no longer contains the full HTTP request and
-response information. You can, however, get access to the request and response object by calling `getRequest()` or
-`getResponse()` on the exception object.
-
-### Query parameter aggregation
-
-Multi-valued query parameters are no longer aggregated using a callback function. `Guzzle\Http\Query` now has a
-setAggregator() method that accepts a `Guzzle\Http\QueryAggregator\QueryAggregatorInterface` object. This object is
-responsible for handling the aggregation of multi-valued query string variables into a flattened hash.
-
-2.8 to 3.x
-----------
-
-### Guzzle\Service\Inspector
-
-Change `\Guzzle\Service\Inspector::fromConfig` to `\Guzzle\Common\Collection::fromConfig`
-
-**Before**
-
-```php
-use Guzzle\Service\Inspector;
-
-class YourClient extends \Guzzle\Service\Client
-{
-    public static function factory($config = array())
-    {
-        $default = array();
-        $required = array('base_url', 'username', 'api_key');
-        $config = Inspector::fromConfig($config, $default, $required);
-
-        $client = new self(
-            $config->get('base_url'),
-            $config->get('username'),
-            $config->get('api_key')
-        );
-        $client->setConfig($config);
-
-        $client->setDescription(ServiceDescription::factory(__DIR__ . DIRECTORY_SEPARATOR . 'client.json'));
-
-        return $client;
-    }
-```
-
-**After**
-
-```php
-use Guzzle\Common\Collection;
-
-class YourClient extends \Guzzle\Service\Client
-{
-    public static function factory($config = array())
-    {
-        $default = array();
-        $required = array('base_url', 'username', 'api_key');
-        $config = Collection::fromConfig($config, $default, $required);
-
-        $client = new self(
-            $config->get('base_url'),
-            $config->get('username'),
-            $config->get('api_key')
-        );
-        $client->setConfig($config);
-
-        $client->setDescription(ServiceDescription::factory(__DIR__ . DIRECTORY_SEPARATOR . 'client.json'));
-
-        return $client;

-(See #217) (Fixed in 09daeb8c666fb44499a0646d655a8ae36456575e)
-
-In version 2.8 setting the `Accept-Encoding` header would set the CURLOPT_ENCODING option, which permitted cURL to
-properly handle gzip/deflate compressed responses from the server. In versions affected by this bug this does not happen.
-See issue #217 for a workaround, or use a version containing the fix.

-# Features
-
-- [Promises/A+](https://promisesaplus.com/) implementation.
-- Promise resolution and chaining is handled iteratively, allowing for
-  "infinite" promise chaining.
-- Promises have a synchronous `wait` method.
-- Promises can be cancelled.
-- Works with any object that has a `then` function.
-- C# style async/await coroutine promises using
-  `GuzzleHttp\Promise\coroutine()`.
-
-
-# Quick start
-
-A *promise* represents the eventual result of an asynchronous operation. The
-primary way of interacting with a promise is through its `then` method, which
-registers callbacks to receive either a promise's eventual value or the reason
-why the promise cannot be fulfilled.
-
-
-## Callbacks
-
-Callbacks are registered with the `then` method by providing an optional 
-`$onFulfilled` followed by an optional `$onRejected` function.
-
-
-```php
-use GuzzleHttp\Promise\Promise;
-
-$promise = new Promise();
-$promise->then(
-    // $onFulfilled
-    function ($value) {
-        echo 'The promise was fulfilled.';
-    },
-    // $onRejected
-    function ($reason) {
-        echo 'The promise was rejected.';
-    }
-);
-```
-
-*Resolving* a promise means that you either fulfill a promise with a *value* or
-reject a promise with a *reason*. Resolving a promises triggers callbacks
-registered with the promises's `then` method. These callbacks are triggered
-only once and in the order in which they were added.
-
-
-## Resolving a promise
-
-Promises are fulfilled using the `resolve($value)` method. Resolving a promise
-with any value other than a `GuzzleHttp\Promise\RejectedPromise` will trigger
-all of the onFulfilled callbacks (resolving a promise with a rejected promise
-will reject the promise and trigger the `$onRejected` callbacks).
-
-```php
-use GuzzleHttp\Promise\Promise;
-
-$promise = new Promise();
-$promise
-    ->then(function ($value) {
-        // Return a value and don't break the chain
-        return "Hello, " . $value;
-    })
-    // This then is executed after the first then and receives the value
-    // returned from the first then.
-    ->then(function ($value) {
-        echo $value;
-    });
-
-// Resolving the promise triggers the $onFulfilled callbacks and outputs
-// "Hello, reader".
-$promise->resolve('reader.');
-```
-
-
-## Promise forwarding
-
-Promises can be chained one after the other. Each then in the chain is a new
-promise. The return value of a promise is what's forwarded to the next
-promise in the chain. Returning a promise in a `then` callback will cause the
-subsequent promises in the chain to only be fulfilled when the returned promise
-has been fulfilled. The next promise in the chain will be invoked with the
-resolved value of the promise.
-
-```php
-use GuzzleHttp\Promise\Promise;
-
-$promise = new Promise();
-$nextPromise = new Promise();
-
-$promise
-    ->then(function ($value) use ($nextPromise) {
-        echo $value;
-        return $nextPromise;
-    })
-    ->then(function ($value) {
-        echo $value;
-    });
-
-// Triggers the first callback and outputs "A"
-$promise->resolve('A');
-// Triggers the second callback and outputs "B"
-$nextPromise->resolve('B');
-```
-
-## Promise rejection
-
-When a promise is rejected, the `$onRejected` callbacks are invoked with the
-rejection reason.
-
-```php
-use GuzzleHttp\Promise\Promise;
-
-$promise = new Promise();
-$promise->then(null, function ($reason) {
-    echo $reason;
-});
-
-$promise->reject('Error!');
-// Outputs "Error!"
-```
-
-## Rejection forwarding
-
-If an exception is thrown in an `$onRejected` callback, subsequent
-`$onRejected` callbacks are invoked with the thrown exception as the reason.
-
-```php
-use GuzzleHttp\Promise\Promise;
-
-$promise = new Promise();
-$promise->then(null, function ($reason) {
-    throw new \Exception($reason);
-})->then(null, function ($reason) {
-    assert($reason->getMessage() === 'Error!');
-});
-
-$promise->reject('Error!');
-```
-
-You can also forward a rejection down the promise chain by returning a
-`GuzzleHttp\Promise\RejectedPromise` in either an `$onFulfilled` or
-`$onRejected` callback.
-
-```php
-use GuzzleHttp\Promise\Promise;
-use GuzzleHttp\Promise\RejectedPromise;
-
-$promise = new Promise();
-$promise->then(null, function ($reason) {
-    return new RejectedPromise($reason);
-})->then(null, function ($reason) {
-    assert($reason === 'Error!');
-});
-
-$promise->reject('Error!');
-```
-
-If an exception is not thrown in a `$onRejected` callback and the callback
-does not return a rejected promise, downstream `$onFulfilled` callbacks are
-invoked using the value returned from the `$onRejected` callback.
-
-```php
-use GuzzleHttp\Promise\Promise;
-use GuzzleHttp\Promise\RejectedPromise;
-
-$promise = new Promise();
-$promise
-    ->then(null, function ($reason) {
-        return "It's ok";
-    })
-    ->then(function ($value) {
-        assert($value === "It's ok");
-    });
-
-$promise->reject('Error!');
-```
-
-# Synchronous wait
-
-You can synchronously force promises to complete using a promise's `wait`
-method. When creating a promise, you can provide a wait function that is used
-to synchronously force a promise to complete. When a wait function is invoked
-it is expected to deliver a value to the promise or reject the promise. If the
-wait function does not deliver a value, then an exception is thrown. The wait
-function provided to a promise constructor is invoked when the `wait` function
-of the promise is called.
-
-```php
-$promise = new Promise(function () use (&$promise) {
-    $promise->resolve('foo');
-});
-
-// Calling wait will return the value of the promise.
-echo $promise->wait(); // outputs "foo"
-```
-
-If an exception is encountered while invoking the wait function of a promise,
-the promise is rejected with the exception and the exception is thrown.
-
-```php
-$promise = new Promise(function () use (&$promise) {
-    throw new \Exception('foo');
-});
-
-$promise->wait(); // throws the exception.
-```
-
-Calling `wait` on a promise that has been fulfilled will not trigger the wait
-function. It will simply return the previously resolved value.
-
-```php
-$promise = new Promise(function () { die('this is not called!'); });
-$promise->resolve('foo');
-echo $promise->wait(); // outputs "foo"
-```
-
-Calling `wait` on a promise that has been rejected will throw an exception. If
-the rejection reason is an instance of `\Exception` the reason is thrown.
-Otherwise, a `GuzzleHttp\Promise\RejectionException` is thrown and the reason
-can be obtained by calling the `getReason` method of the exception.
-
-```php
-$promise = new Promise();
-$promise->reject('foo');
-$promise->wait();
-```
-
-> PHP Fatal error:  Uncaught exception 'GuzzleHttp\Promise\RejectionException' with message 'The promise was rejected with value: foo'
-
-
-## Unwrapping a promise
-
-When synchronously waiting on a promise, you are joining the state of the
-promise into the current state of execution (i.e., return the value of the
-promise if it was fulfilled or throw an exception if it was rejected). This is
-called "unwrapping" the promise. Waiting on a promise will by default unwrap
-the promise state.
-
-You can force a promise to resolve and *not* unwrap the state of the promise
-by passing `false` to the first argument of the `wait` function:
-
-```php
-$promise = new Promise();
-$promise->reject('foo');
-// This will not throw an exception. It simply ensures the promise has
-// been resolved.
-$promise->wait(false);
-```
-
-When unwrapping a promise, the resolved value of the promise will be waited
-upon until the unwrapped value is not a promise. This means that if you resolve
-promise A with a promise B and unwrap promise A, the value returned by the
-wait function will be the value delivered to promise B.
-
-**Note**: when you do not unwrap the promise, no value is returned.
-
-
-# Cancellation
-
-You can cancel a promise that has not yet been fulfilled using the `cancel()`
-method of a promise. When creating a promise you can provide an optional
-cancel function that when invoked cancels the action of computing a resolution
-of the promise.
-
-
-# API
-
-
-## Promise
-
-When creating a promise object, you can provide an optional `$waitFn` and
-`$cancelFn`. `$waitFn` is a function that is invoked with no arguments and is
-expected to resolve the promise. `$cancelFn` is a function with no arguments
-that is expected to cancel the computation of a promise. It is invoked when the
-`cancel()` method of a promise is called.
-
-```php
-use GuzzleHttp\Promise\Promise;
-
-$promise = new Promise(
-    function () use (&$promise) {
-        $promise->resolve('waited');
-    },
-    function () {
-        // do something that will cancel the promise computation (e.g., close
-        // a socket, cancel a database query, etc...)
-    }
-);
-
-assert('waited' === $promise->wait());
-```
-
-A promise has the following methods:
-
-- `then(callable $onFulfilled, callable $onRejected) : PromiseInterface`
-  
-  Appends fulfillment and rejection handlers to the promise, and returns a new promise resolving to the return value of the called handler.
-
-- `otherwise(callable $onRejected) : PromiseInterface`
-  
-  Appends a rejection handler callback to the promise, and returns a new promise resolving to the return value of the callback if it is called, or to its original fulfillment value if the promise is instead fulfilled.
-
-- `wait($unwrap = true) : mixed`
-
-  Synchronously waits on the promise to complete.
-  
-  `$unwrap` controls whether or not the value of the promise is returned for a
-  fulfilled promise or if an exception is thrown if the promise is rejected.
-  This is set to `true` by default.
-
-- `cancel()`
-
-  Attempts to cancel the promise if possible. The promise being cancelled and
-  the parent most ancestor that has not yet been resolved will also be
-  cancelled. Any promises waiting on the cancelled promise to resolve will also
-  be cancelled.
-
-- `getState() : string`
-
-  Returns the state of the promise. One of `pending`, `fulfilled`, or
-  `rejected`.
-
-- `resolve($value)`
-
-  Fulfills the promise with the given `$value`.

-- `reject($reason)`
-
-  Rejects the promise with the given `$reason`.
-
-
-## FulfilledPromise
-
-A fulfilled promise can be created to represent a promise that has been
-fulfilled.
-
-```php
-use GuzzleHttp\Promise\FulfilledPromise;
-
-$promise = new FulfilledPromise('value');
-
-// Fulfilled callbacks are immediately invoked.
-$promise->then(function ($value) {
-    echo $value;
-});
-```
-
-
-## RejectedPromise
-
-A rejected promise can be created to represent a promise that has been
-rejected.
-
-```php
-use GuzzleHttp\Promise\RejectedPromise;
-
-$promise = new RejectedPromise('Error');
-
-// Rejected callbacks are immediately invoked.
-$promise->then(null, function ($reason) {
-    echo $reason;
-});
-```
-
-
-# Promise interop
-
-This library works with foreign promises that have a `then` method. This means
-you can use Guzzle promises with [React promises](https://github.com/reactphp/promise)
-for example. When a foreign promise is returned inside of a then method
-callback, promise resolution will occur recursively.
-
-```php
-// Create a React promise
-$deferred = new React\Promise\Deferred();
-$reactPromise = $deferred->promise();
-
-// Create a Guzzle promise that is fulfilled with a React promise.
-$guzzlePromise = new \GuzzleHttp\Promise\Promise();
-$guzzlePromise->then(function ($value) use ($reactPromise) {
-    // Do something something with the value...
-    // Return the React promise
-    return $reactPromise;
-});
-```
-
-Please note that wait and cancel chaining is no longer possible when forwarding
-a foreign promise. You will need to wrap a third-party promise with a Guzzle
-promise in order to utilize wait and cancel functions with foreign promises.
-
-
-## Event Loop Integration
-
-In order to keep the stack size constant, Guzzle promises are resolved
-asynchronously using a task queue. When waiting on promises synchronously, the
-task queue will be automatically run to ensure that the blocking promise and
-any forwarded promises are resolved. When using promises asynchronously in an
-event loop, you will need to run the task queue on each tick of the loop. If
-you do not run the task queue, then promises will not be resolved.
-
-You can run the task queue using the `run()` method of the global task queue
-instance.
-
-```php
-// Get the global task queue
-$queue = \GuzzleHttp\Promise\queue();
-$queue->run();
-```
-
-For example, you could use Guzzle promises with React using a periodic timer:
-
-```php
-$loop = React\EventLoop\Factory::create();
-$loop->addPeriodicTimer(0, [$queue, 'run']);
-```
-
-*TODO*: Perhaps adding a `futureTick()` on each tick would be faster?
-
-
-# Implementation notes
-
-
-## Promise resolution and chaining is handled iteratively
-
-By shuffling pending handlers from one owner to another, promises are
-resolved iteratively, allowing for "infinite" then chaining.
-
-```php
-<?php
-require 'vendor/autoload.php';
-
-use GuzzleHttp\Promise\Promise;
-
-$parent = new Promise();
-$p = $parent;
-
-for ($i = 0; $i < 1000; $i++) {
-    $p = $p->then(function ($v) {
-        // The stack size remains constant (a good thing)
-        echo xdebug_get_stack_depth() . ', ';
-        return $v + 1;
-    });
-}
-
-$parent->resolve(0);
-var_dump($p->wait()); // int(1000)
-
-```
-
-When a promise is fulfilled or rejected with a non-promise value, the promise
-then takes ownership of the handlers of each child promise and delivers values
-down the chain without using recursion.
-
-When a promise is resolved with another promise, the original promise transfers
-all of its pending handlers to the new promise. When the new promise is
-eventually resolved, all of the pending handlers are delivered the forwarded
-value.
-
-
-## A promise is the deferred.
-
-Some promise libraries implement promises using a deferred object to represent
-a computation and a promise object to represent the delivery of the result of
-the computation. This is a nice separation of computation and delivery because
-consumers of the promise cannot modify the value that will be eventually
-delivered.
-
-One side effect of being able to implement promise resolution and chaining
-iteratively is that you need to be able for one promise to reach into the state
-of another promise to shuffle around ownership of handlers. In order to achieve
-this without making the handlers of a promise publicly mutable, a promise is
-also the deferred value, allowing promises of the same parent class to reach
-into and modify the private properties of promises of the same type. While this
-does allow consumers of the value to modify the resolution or rejection of the
-deferred, it is a small price to pay for keeping the stack size constant.
-
-```php
-$promise = new Promise();
-$promise->then(function ($value) { echo $value; });
-// The promise is the deferred value, so you can deliver a value to it.
-$promise->resolve('foo');
-// prints "foo"
-```

-# CHANGELOG
-
-## 1.4.2 - 2017-03-20
-
-* Reverted BC break to `Uri::resolve` and `Uri::removeDotSegments` by removing 
-  calls to `trigger_error` when deprecated methods are invoked.
-
-## 1.4.1 - 2017-02-27
-
-* Reverted BC break by reintroducing behavior to automagically fix a URI with a
-  relative path and an authority by adding a leading slash to the path. It's only
-  deprecated now.
-* Added triggering of silenced deprecation warnings.
-
-## 1.4.0 - 2017-02-21
-
-* Fix `Stream::read` when length parameter <= 0.
-* `copy_to_stream` reads bytes in chunks instead of `maxLen` into memory.
-* Fix `ServerRequest::getUriFromGlobals` when `Host` header contains port.
-* Ensure `ServerRequest::getUriFromGlobals` returns a URI in absolute form.
-* Allow `parse_response` to parse a response without delimiting space and reason.
-* Ensure each URI modification results in a valid URI according to PSR-7 discussions.
-  Invalid modifications will throw an exception instead of returning a wrong URI or
-  doing some magic.
-  - `(new Uri)->withPath('foo')->withHost('example.com')` will throw an exception
-    because the path of a URI with an authority must start with a slash "/" or be empty
-  - `(new Uri())->withScheme('http')` will return `'http://localhost'`
-* Fix compatibility of URIs with `file` scheme and empty host.
-* Added common URI utility methods based on RFC 3986 (see documentation in the readme):
-  - `Uri::isDefaultPort`
-  - `Uri::isAbsolute`
-  - `Uri::isNetworkPathReference`
-  - `Uri::isAbsolutePathReference`
-  - `Uri::isRelativePathReference`
-  - `Uri::isSameDocumentReference`
-  - `Uri::composeComponents`
-  - `UriNormalizer::normalize`
-  - `UriNormalizer::isEquivalent`
-  - `UriResolver::relativize`
-* Deprecated `Uri::resolve` in favor of `UriResolver::resolve`
-* Deprecated `Uri::removeDotSegments` in favor of `UriResolver::removeDotSegments`
-
-## 1.3.1 - 2016-06-25
-
-* Fix `Uri::__toString` for network path references, e.g. `//example.org`.
-* Fix missing lowercase normalization for host.
-* Fix handling of URI components in case they are `'0'` in a lot of places,
-  e.g. as a user info password.
-* Fix `Uri::withAddedHeader` to correctly merge headers with different case.
-* Fix trimming of header values in `Uri::withAddedHeader`. Header values may
-  be surrounded by whitespace which should be ignored according to RFC 7230
-  Section 3.2.4. This does not apply to header names.
-* Fix `Uri::withAddedHeader` with an array of header values.
-* Fix `Uri::resolve` when base path has no slash and handling of fragment.
-* Fix handling of encoding in `Uri::with(out)QueryValue` so one can pass the
-  key/value both in encoded as well as decoded form to those methods. This is
-  consistent with withPath, withQuery etc.
-* Fix `ServerRequest::withoutAttribute` when attribute value is null.
-
-## 1.3.0 - 2016-04-13
-
-* Added remaining interfaces needed for full PSR7 compatibility
-  (ServerRequestInterface, UploadedFileInterface, etc.).
-* Added support for stream_for from scalars.
-* Can now extend Uri.
-* Fixed a bug in validating request methods by making it more permissive.
-
-## 1.2.3 - 2016-02-18
-
-* Fixed support in `GuzzleHttp\Psr7\CachingStream` for seeking forward on remote
-  streams, which can sometimes return fewer bytes than requested with `fread`.
-* Fixed handling of gzipped responses with FNAME headers.
-
-## 1.2.2 - 2016-01-22
-
-* Added support for URIs without any authority.
-* Added support for HTTP 451 'Unavailable For Legal Reasons.'
-* Added support for using '0' as a filename.
-* Added support for including non-standard ports in Host headers.
-
-## 1.2.1 - 2015-11-02
-
-* Now supporting negative offsets when seeking to SEEK_END.
-
-## 1.2.0 - 2015-08-15
-
-* Body as `"0"` is now properly added to a response.
-* Now allowing forward seeking in CachingStream.
-* Now properly parsing HTTP requests that contain proxy targets in
-  `parse_request`.
-* functions.php is now conditionally required.
-* user-info is no longer dropped when resolving URIs.
-
-## 1.1.0 - 2015-06-24
-
-* URIs can now be relative.
-* `multipart/form-data` headers are now overridden case-insensitively.
-* URI paths no longer encode the following characters because they are allowed
-  in URIs: "(", ")", "*", "!", "'"
-* A port is no longer added to a URI when the scheme is missing and no port is
-  present.

-# PSR-7 Message Implementation
-
-This repository contains a full [PSR-7](http://www.php-fig.org/psr/psr-7/)
-message implementation, several stream decorators, and some helpful
-functionality like query string parsing.
-
-
-[![Build Status](https://travis-ci.org/guzzle/psr7.svg?branch=master)](https://travis-ci.org/guzzle/psr7)
-
-
-# Stream implementation
-
-This package comes with a number of stream implementations and stream
-decorators.
-
-
-## AppendStream
-
-`GuzzleHttp\Psr7\AppendStream`
-
-Reads from multiple streams, one after the other.
-
-```php
-use GuzzleHttp\Psr7;
-
-$a = Psr7\stream_for('abc, ');
-$b = Psr7\stream_for('123.');
-$composed = new Psr7\AppendStream([$a, $b]);
-
-$composed->addStream(Psr7\stream_for(' Above all listen to me'));
-
-echo $composed; // abc, 123. Above all listen to me.
-```
-
-
-## BufferStream
-
-`GuzzleHttp\Psr7\BufferStream`
-
-Provides a buffer stream that can be written to fill a buffer, and read
-from to remove bytes from the buffer.
-
-This stream returns a "hwm" metadata value that tells upstream consumers
-what the configured high water mark of the stream is, or the maximum
-preferred size of the buffer.
-
-```php
-use GuzzleHttp\Psr7;
-
-// When more than 1024 bytes are in the buffer, it will begin returning
-// false to writes. This is an indication that writers should slow down.
-$buffer = new Psr7\BufferStream(1024);
-```
-
-
-## CachingStream
-
-The CachingStream is used to allow seeking over previously read bytes on
-non-seekable streams. This can be useful when transferring a non-seekable
-entity body fails due to needing to rewind the stream (for example, resulting
-from a redirect). Data that is read from the remote stream will be buffered in
-a PHP temp stream so that previously read bytes are cached first in memory,
-then on disk.
-
-```php
-use GuzzleHttp\Psr7;
-
-$original = Psr7\stream_for(fopen('http://www.google.com', 'r'));
-$stream = new Psr7\CachingStream($original);
-
-$stream->read(1024);
-echo $stream->tell();
-// 1024
-
-$stream->seek(0);
-echo $stream->tell();
-// 0
-```
-
-
-## DroppingStream
-
-`GuzzleHttp\Psr7\DroppingStream`
-
-Stream decorator that begins dropping data once the size of the underlying
-stream becomes too full.
-
-```php
-use GuzzleHttp\Psr7;
-
-// Create an empty stream
-$stream = Psr7\stream_for();
-
-// Start dropping data when the stream has more than 10 bytes
-$dropping = new Psr7\DroppingStream($stream, 10);
-
-$dropping->write('01234567890123456789');
-echo $stream; // 0123456789
-```
-
-
-## FnStream
-
-`GuzzleHttp\Psr7\FnStream`
-
-Compose stream implementations based on a hash of functions.
-
-Allows for easy testing and extension of a provided stream without needing
-to create a concrete class for a simple extension point.
-
-```php
-
-use GuzzleHttp\Psr7;
-
-$stream = Psr7\stream_for('hi');
-$fnStream = Psr7\FnStream::decorate($stream, [
-    'rewind' => function () use ($stream) {
-        echo 'About to rewind - ';
-        $stream->rewind();
-        echo 'rewound!';
-    }
-]);
-
-$fnStream->rewind();
-// Outputs: About to rewind - rewound!
-```
-
-
-## InflateStream
-
-`GuzzleHttp\Psr7\InflateStream`
-
-Uses PHP's zlib.inflate filter to inflate deflate or gzipped content.
-
-This stream decorator skips the first 10 bytes of the given stream to remove
-the gzip header, converts the provided stream to a PHP stream resource,
-then appends the zlib.inflate filter. The stream is then converted back
-to a Guzzle stream resource to be used as a Guzzle stream.
-
-
-## LazyOpenStream
-
-`GuzzleHttp\Psr7\LazyOpenStream`
-
-Lazily reads or writes to a file that is opened only after an IO operation
-take place on the stream.
-
-```php
-use GuzzleHttp\Psr7;
-
-$stream = new Psr7\LazyOpenStream('/path/to/file', 'r');
-// The file has not yet been opened...
-
-echo $stream->read(10);
-// The file is opened and read from only when needed.
-```
-
-
-## LimitStream
-
-`GuzzleHttp\Psr7\LimitStream`
-
-LimitStream can be used to read a subset or slice of an existing stream object.
-This can be useful for breaking a large file into smaller pieces to be sent in
-chunks (e.g. Amazon S3's multipart upload API).
-
-```php
-use GuzzleHttp\Psr7;
-
-$original = Psr7\stream_for(fopen('/tmp/test.txt', 'r+'));
-echo $original->getSize();
-// >>> 1048576
-
-// Limit the size of the body to 1024 bytes and start reading from byte 2048
-$stream = new Psr7\LimitStream($original, 1024, 2048);
-echo $stream->getSize();
-// >>> 1024
-echo $stream->tell();
-// >>> 0
-```
-
-
-## MultipartStream
-
-`GuzzleHttp\Psr7\MultipartStream`
-
-Stream that when read returns bytes for a streaming multipart or
-multipart/form-data stream.
-
-
-## NoSeekStream
-
-`GuzzleHttp\Psr7\NoSeekStream`
-
-NoSeekStream wraps a stream and does not allow seeking.
-
-```php
-use GuzzleHttp\Psr7;
-
-$original = Psr7\stream_for('foo');
-$noSeek = new Psr7\NoSeekStream($original);
-
-echo $noSeek->read(3);
-// foo
-var_export($noSeek->isSeekable());
-// false
-$noSeek->seek(0);
-var_export($noSeek->read(3));
-// NULL
-```
-
-
-## PumpStream
-
-`GuzzleHttp\Psr7\PumpStream`
-
-Provides a read only stream that pumps data from a PHP callable.
-
-When invoking the provided callable, the PumpStream will pass the amount of
-data requested to read to the callable. The callable can choose to ignore
-this value and return fewer or more bytes than requested. Any extra data
-returned by the provided callable is buffered internally until drained using
-the read() function of the PumpStream. The provided callable MUST return
-false when there is no more data to read.
-
-
-## Implementing stream decorators
-
-Creating a stream decorator is very easy thanks to the
-`GuzzleHttp\Psr7\StreamDecoratorTrait`. This trait provides methods that
-implement `Psr\Http\Message\StreamInterface` by proxying to an underlying
-stream. Just `use` the `StreamDecoratorTrait` and implement your custom
-methods.
-
-For example, let's say we wanted to call a specific function each time the last
-byte is read from a stream. This could be implemented by overriding the
-`read()` method.
-
-```php
-use Psr\Http\Message\StreamInterface;
-use GuzzleHttp\Psr7\StreamDecoratorTrait;
-
-class EofCallbackStream implements StreamInterface
-{
-    use StreamDecoratorTrait;
-
-    private $callback;
-
-    public function __construct(StreamInterface $stream, callable $cb)
-    {
-        $this->stream = $stream;
-        $this->callback = $cb;
-    }
-
-    public function read($length)
-    {
-        $result = $this->stream->read($length);
-
-        // Invoke the callback when EOF is hit.
-        if ($this->eof()) {
-            call_user_func($this->callback);
-        }
-
-        return $result;
-    }
-}
-```
-
-This decorator could be added to any existing stream and used like so:
-
-```php
-use GuzzleHttp\Psr7;
-
-$original = Psr7\stream_for('foo');
-
-$eofStream = new EofCallbackStream($original, function () {
-    echo 'EOF!';
-});
-
-$eofStream->read(2);
-$eofStream->read(1);
-// echoes "EOF!"
-$eofStream->seek(0);
-$eofStream->read(3);
-// echoes "EOF!"
-```
-
-
-## PHP StreamWrapper
-
-You can use the `GuzzleHttp\Psr7\StreamWrapper` class if you need to use a
-PSR-7 stream as a PHP stream resource.
-
-Use the `GuzzleHttp\Psr7\StreamWrapper::getResource()` method to create a PHP
-stream from a PSR-7 stream.
-
-```php
-use GuzzleHttp\Psr7\StreamWrapper;
-
-$stream = GuzzleHttp\Psr7\stream_for('hello!');
-$resource = StreamWrapper::getResource($stream);
-echo fread($resource, 6); // outputs hello!
-```
-
-
-# Function API
-
-There are various functions available under the `GuzzleHttp\Psr7` namespace.
-
-
-## `function str`
-
-`function str(MessageInterface $message)`
-
-Returns the string representation of an HTTP message.
-
-```php
-$request = new GuzzleHttp\Psr7\Request('GET', 'http://example.com');
-echo GuzzleHttp\Psr7\str($request);
-```
-
-
-## `function uri_for`
-
-`function uri_for($uri)`
-
-This function accepts a string or `Psr\Http\Message\UriInterface` and returns a
-UriInterface for the given value. If the value is already a `UriInterface`, it
-is returned as-is.
-
-```php
-$uri = GuzzleHttp\Psr7\uri_for('http://example.com');
-assert($uri === GuzzleHttp\Psr7\uri_for($uri));
-```
-
-
-## `function stream_for`
-
-`function stream_for($resource = '', array $options = [])`
-
-Create a new stream based on the input type.
-
-Options is an associative array that can contain the following keys:
-
-* - metadata: Array of custom metadata.
-* - size: Size of the stream.
-
-This method accepts the following `$resource` types:
-
-- `Psr\Http\Message\StreamInterface`: Returns the value as-is.
-- `string`: Creates a stream object that uses the given string as the contents.
-- `resource`: Creates a stream object that wraps the given PHP stream resource.
-- `Iterator`: If the provided value implements `Iterator`, then a read-only
-  stream object will be created that wraps the given iterable. Each time the
-  stream is read from, data from the iterator will fill a buffer and will be
-  continuously called until the buffer is equal to the requested read size.
-  Subsequent read calls will first read from the buffer and then call `next`
-  on the underlying iterator until it is exhausted.
-- `object` with `__toString()`: If the object has the `__toString()` method,
-  the object will be cast to a string and then a stream will be returned that
-  uses the string value.
-- `NULL`: When `null` is passed, an empty stream object is returned.
-- `callable` When a callable is passed, a read-only stream object will be
-  created that invokes the given callable. The callable is invoked with the
-  number of suggested bytes to read. The callable can return any number of
-  bytes, but MUST return `false` when there is no more data to return. The
-  stream object that wraps the callable will invoke the callable until the
-  number of requested bytes are available. Any additional bytes will be
-  buffered and used in subsequent reads.
-
-```php
-$stream = GuzzleHttp\Psr7\stream_for('foo');
-$stream = GuzzleHttp\Psr7\stream_for(fopen('/path/to/file', 'r'));
-
-$generator function ($bytes) {
-    for ($i = 0; $i < $bytes; $i++) {
-        yield ' ';
-    }
-}
-
-$stream = GuzzleHttp\Psr7\stream_for($generator(100));
-```
-
-
-## `function parse_header`
-
-`function parse_header($header)`
-
-Parse an array of header values containing ";" separated data into an array of
-associative arrays representing the header key value pair data of the header.
-When a parameter does not contain a value, but just contains a key, this
-function will inject a key with a '' string value.
-
-
-## `function normalize_header`
-
-`function normalize_header($header)`
-
-Converts an array of header values that may contain comma separated headers
-into an array of headers with no comma separated values.
-
-
-## `function modify_request`
-
-`function modify_request(RequestInterface $request, array $changes)`
-
-Clone and modify a request with the given changes. This method is useful for
-reducing the number of clones needed to mutate a message.
-
-The changes can be one of:
-
-- method: (string) Changes the HTTP method.
-- set_headers: (array) Sets the given headers.
-- remove_headers: (array) Remove the given headers.
-- body: (mixed) Sets the given body.
-- uri: (UriInterface) Set the URI.
-- query: (string) Set the query string value of the URI.
-- version: (string) Set the protocol version.
-
-
-## `function rewind_body`
-
-`function rewind_body(MessageInterface $message)`
-
-Attempts to rewind a message body and throws an exception on failure. The body
-of the message will only be rewound if a call to `tell()` returns a value other
-than `0`.
-
-
-## `function try_fopen`
-
-`function try_fopen($filename, $mode)`
-
-Safely opens a PHP stream resource using a filename.
-
-When fopen fails, PHP normally raises a warning. This function adds an error
-handler that checks for errors and throws an exception instead.
-
-
-## `function copy_to_string`
-
-`function copy_to_string(StreamInterface $stream, $maxLen = -1)`
-
-Copy the contents of a stream into a string until the given number of bytes
-have been read.
-
-
-## `function copy_to_stream`
-
-`function copy_to_stream(StreamInterface $source, StreamInterface $dest, $maxLen = -1)`
-
-Copy the contents of a stream into another stream until the given number of
-bytes have been read.
-
-
-## `function hash`
-
-`function hash(StreamInterface $stream, $algo, $rawOutput = false)`
-
-Calculate a hash of a Stream. This method reads the entire stream to calculate
-a rolling hash (based on PHP's hash_init functions).
-
-
-## `function readline`
-
-`function readline(StreamInterface $stream, $maxLength = null)`
-
-Read a line from the stream up to the maximum allowed buffer length.
-
-
-## `function parse_request`
-
-`function parse_request($message)`
-
-Parses a request message string into a request object.
-
-
-## `function parse_response`
-
-`function parse_response($message)`
-
-Parses a response message string into a response object.
-
-
-## `function parse_query`
-
-`function parse_query($str, $urlEncoding = true)`
-
-Parse a query string into an associative array.
-
-If multiple values are found for the same key, the value of that key value pair
-will become an array. This function does not parse nested PHP style arrays into
-an associative array (e.g., `foo[a]=1&foo[b]=2` will be parsed into
-`['foo[a]' => '1', 'foo[b]' => '2']`).
-
-
-## `function build_query`
-
-`function build_query(array $params, $encoding = PHP_QUERY_RFC3986)`
-
-Build a query string from an array of key value pairs.
-
-This function can use the return value of parse_query() to build a query string.
-This function does not modify the provided keys when an array is encountered
-(like http_build_query would).
-
-
-## `function mimetype_from_filename`
-
-`function mimetype_from_filename($filename)`
-
-Determines the mimetype of a file by looking at its extension.
-
-
-## `function mimetype_from_extension`
-
-`function mimetype_from_extension($extension)`
-
-Maps a file extensions to a mimetype.
-
-
-# Additional URI Methods
-
-Aside from the standard `Psr\Http\Message\UriInterface` implementation in form of the `GuzzleHttp\Psr7\Uri` class,
-this library also provides additional functionality when working with URIs as static methods.
-
-## URI Types
-
-An instance of `Psr\Http\Message\UriInterface` can either be an absolute URI or a relative reference.
-An absolute URI has a scheme. A relative reference is used to express a URI relative to another URI,
-the base URI. Relative references can be divided into several forms according to
-[RFC 3986 Section 4.2](https://tools.ietf.org/html/rfc3986#section-4.2):
-
-- network-path references, e.g. `//example.com/path`
-- absolute-path references, e.g. `/path`
-- relative-path references, e.g. `subpath`
-
-The following methods can be used to identify the type of the URI.
-
-### `GuzzleHttp\Psr7\Uri::isAbsolute`
-
-`public static function isAbsolute(UriInterface $uri): bool`
-
-Whether the URI is absolute, i.e. it has a scheme.
-
-### `GuzzleHttp\Psr7\Uri::isNetworkPathReference`
-
-`public static function isNetworkPathReference(UriInterface $uri): bool`
-
-Whether the URI is a network-path reference. A relative reference that begins with two slash characters is
-termed an network-path reference.
-
-### `GuzzleHttp\Psr7\Uri::isAbsolutePathReference`
-
-`public static function isAbsolutePathReference(UriInterface $uri): bool`
-
-Whether the URI is a absolute-path reference. A relative reference that begins with a single slash character is
-termed an absolute-path reference.
-
-### `GuzzleHttp\Psr7\Uri::isRelativePathReference`
-
-`public static function isRelativePathReference(UriInterface $uri): bool`
-
-Whether the URI is a relative-path reference. A relative reference that does not begin with a slash character is
-termed a relative-path reference.
-
-### `GuzzleHttp\Psr7\Uri::isSameDocumentReference`
-
-`public static function isSameDocumentReference(UriInterface $uri, UriInterface $base = null): bool`
-
-Whether the URI is a same-document reference. A same-document reference refers to a URI that is, aside from its
-fragment component, identical to the base URI. When no base URI is given, only an empty URI reference
-(apart from its fragment) is considered a same-document reference.
-
-## URI Components
-
-Additional methods to work with URI components.
-
-### `GuzzleHttp\Psr7\Uri::isDefaultPort`
-
-`public static function isDefaultPort(UriInterface $uri): bool`
-
-Whether the URI has the default port of the current scheme. `Psr\Http\Message\UriInterface::getPort` may return null
-or the standard port. This method can be used independently of the implementation.
-
-### `GuzzleHttp\Psr7\Uri::composeComponents`
-
-`public static function composeComponents($scheme, $authority, $path, $query, $fragment): string`
-
-Composes a URI reference string from its various components according to
-[RFC 3986 Section 5.3](https://tools.ietf.org/html/rfc3986#section-5.3). Usually this method does not need to be called
-manually but instead is used indirectly via `Psr\Http\Message\UriInterface::__toString`.
-
-### `GuzzleHttp\Psr7\Uri::fromParts`
-
-`public static function fromParts(array $parts): UriInterface`
-
-Creates a URI from a hash of [`parse_url`](http://php.net/manual/en/function.parse-url.php) components.
-
-
-### `GuzzleHttp\Psr7\Uri::withQueryValue`
-
-`public static function withQueryValue(UriInterface $uri, $key, $value): UriInterface`
-
-Creates a new URI with a specific query string value. Any existing query string values that exactly match the
-provided key are removed and replaced with the given key value pair. A value of null will set the query string
-key without a value, e.g. "key" instead of "key=value".
-
-
-### `GuzzleHttp\Psr7\Uri::withoutQueryValue`
-
-`public static function withoutQueryValue(UriInterface $uri, $key): UriInterface`
-
-Creates a new URI with a specific query string value removed. Any existing query string values that exactly match the
-provided key are removed.
-
-## Reference Resolution
-
-`GuzzleHttp\Psr7\UriResolver` provides methods to resolve a URI reference in the context of a base URI according
-to [RFC 3986 Section 5](https://tools.ietf.org/html/rfc3986#section-5). This is for example also what web browsers
-do when resolving a link in a website based on the current request URI.
-
-### `GuzzleHttp\Psr7\UriResolver::resolve`
-
-`public static function resolve(UriInterface $base, UriInterface $rel): UriInterface`
-
-Converts the relative URI into a new URI that is resolved against the base URI.
-
-### `GuzzleHttp\Psr7\UriResolver::removeDotSegments`
-
-`public static function removeDotSegments(string $path): string`
-
-Removes dot segments from a path and returns the new path according to
-[RFC 3986 Section 5.2.4](https://tools.ietf.org/html/rfc3986#section-5.2.4).
-
-### `GuzzleHttp\Psr7\UriResolver::relativize`
-
-`public static function relativize(UriInterface $base, UriInterface $target): UriInterface`
-
-Returns the target URI as a relative reference from the base URI. This method is the counterpart to resolve():
-
-```php
-(string) $target === (string) UriResolver::resolve($base, UriResolver::relativize($base, $target))
-```
-
-One use-case is to use the current request URI as base URI and then generate relative links in your documents
-to reduce the document size or offer self-contained downloadable document archives.
-
-```php
-$base = new Uri('http://example.com/a/b/');
-echo UriResolver::relativize($base, new Uri('http://example.com/a/b/c'));  // prints 'c'.
-echo UriResolver::relativize($base, new Uri('http://example.com/a/x/y'));  // prints '../x/y'.
-echo UriResolver::relativize($base, new Uri('http://example.com/a/b/?q')); // prints '?q'.
-echo UriResolver::relativize($base, new Uri('http://example.org/a/b/'));   // prints '//example.org/a/b/'.
-```
-
-## Normalization and Comparison
-
-`GuzzleHttp\Psr7\UriNormalizer` provides methods to normalize and compare URIs according to
-[RFC 3986 Section 6](https://tools.ietf.org/html/rfc3986#section-6).
-
-### `GuzzleHttp\Psr7\UriNormalizer::normalize`
-
-`public static function normalize(UriInterface $uri, $flags = self::PRESERVING_NORMALIZATIONS): UriInterface`
-
-Returns a normalized URI. The scheme and host component are already normalized to lowercase per PSR-7 UriInterface.
-This methods adds additional normalizations that can be configured with the `$flags` parameter which is a bitmask
-of normalizations to apply. The following normalizations are available:
-
-- `UriNormalizer::PRESERVING_NORMALIZATIONS`
-
-    Default normalizations which only include the ones that preserve semantics.
-
-- `UriNormalizer::CAPITALIZE_PERCENT_ENCODING`
-
-    All letters within a percent-encoding triplet (e.g., "%3A") are case-insensitive, and should be capitalized.
-
-    Example: `http://example.org/a%c2%b1b` → `http://example.org/a%C2%B1b`
-
-- `UriNormalizer::DECODE_UNRESERVED_CHARACTERS`
-
-    Decodes percent-encoded octets of unreserved characters. For consistency, percent-encoded octets in the ranges of
-    ALPHA (%41–%5A and %61–%7A), DIGIT (%30–%39), hyphen (%2D), period (%2E), underscore (%5F), or tilde (%7E) should
-    not be created by URI producers and, when found in a URI, should be decoded to their corresponding unreserved
-    characters by URI normalizers.
-
-    Example: `http://example.org/%7Eusern%61me/` → `http://example.org/~username/`
-
-- `UriNormalizer::CONVERT_EMPTY_PATH`
-
-    Converts the empty path to "/" for http and https URIs.
-
-    Example: `http://example.org` → `http://example.org/`
-
-- `UriNormalizer::REMOVE_DEFAULT_HOST`
-
-    Removes the default host of the given URI scheme from the URI. Only the "file" scheme defines the default host
-    "localhost". All of `file:/myfile`, `file:///myfile`, and `file://localhost/myfile` are equivalent according to
-    RFC 3986.
-
-    Example: `file://localhost/myfile` → `file:///myfile`
-
-- `UriNormalizer::REMOVE_DEFAULT_PORT`
-
-    Removes the default port of the given URI scheme from the URI.
-
-    Example: `http://example.org:80/` → `http://example.org/`
-
-- `UriNormalizer::REMOVE_DOT_SEGMENTS`
-
-    Removes unnecessary dot-segments. Dot-segments in relative-path references are not removed as it would
-    change the semantics of the URI reference.
-
-    Example: `http://example.org/../a/b/../c/./d.html` → `http://example.org/a/c/d.html`
-
-- `UriNormalizer::REMOVE_DUPLICATE_SLASHES`
-
-    Paths which include two or more adjacent slashes are converted to one. Webservers usually ignore duplicate slashes
-    and treat those URIs equivalent. But in theory those URIs do not need to be equivalent. So this normalization
-    may change the semantics. Encoded slashes (%2F) are not removed.
-
-    Example: `http://example.org//foo///bar.html` → `http://example.org/foo/bar.html`
-
-- `UriNormalizer::SORT_QUERY_PARAMETERS`
-
-    Sort query parameters with their values in alphabetical order. However, the order of parameters in a URI may be
-    significant (this is not defined by the standard). So this normalization is not safe and may change the semantics
-    of the URI.
-
-    Example: `?lang=en&article=fred` → `?article=fred&lang=en`
-
-### `GuzzleHttp\Psr7\UriNormalizer::isEquivalent`
-
-`public static function isEquivalent(UriInterface $uri1, UriInterface $uri2, $normalizations = self::PRESERVING_NORMALIZATIONS): bool`
-
-Whether two URIs can be considered equivalent. Both URIs are normalized automatically before comparison with the given
-`$normalizations` bitmask. The method also accepts relative URI references and returns true when they are equivalent.
-This of course assumes they will be resolved against the same base URI. If this is not the case, determination of
-equivalence or difference of relative references does not mean anything.
