310  `Content-Length` modified to reflect the message size after removing the
311  encoding.
312* Added a more explicit error message when trying to use `form_params` and
313  `multipart` in the same request.
314* Several fixes for HHVM support.
315* Functions are now conditionally required using an additional level of
316  indirection to help with global Composer installations.

325
326## 6.0.0 - 2015-05-26
327
328* See the UPGRADING.md document for more information.
329* Added `multipart` and `form_params` request options.
330* Added `synchronous` request option.
331* Added the `on_headers` request option.
332* Fixed `expect` handling.
333* No longer adding default middlewares in the client ctor. These need to be
334  present on the provided handler in order to work.
335* Requests are no longer initiated when sending async requests with the
336  CurlMultiHandler. This prevents unexpected recursion from requests completing
337  while ticking the cURL loop.
338* Removed the semantics of setting `default` to `true`. This is no longer
339  required now that the cURL loop is not ticked for async requests.
340* Added request and response logging middleware.
341* No longer allowing self signed certificates when using the StreamHandler.
342* Ensuring that `sink` is valid if saving to a file.
343* Request exceptions now include a "handler context" which provides handler
344  specific contextual information.
345* Added `GuzzleHttp\RequestOptions` to allow request options to be applied
346  using constants.
347* `$maxHandles` has been removed from CurlMultiHandler.
348* `MultipartPostBody` is now part of the `guzzlehttp/psr7` package.
349
350## 5.3.0 - 2015-05-19
351
352* Mock now supports `save_to`
353* Marked `AbstractRequestEvent::getTransaction()` as public.
354* Fixed a bug in which multiple headers using different casing would overwrite
355  previous headers in the associative array.
356* Added `Utils::getDefaultHandler()`
357* Marked `GuzzleHttp\Client::getDefaultUserAgent` as deprecated.
358* URL scheme is now always lowercased.
359
360## 6.0.0-beta.1
361
362* Requires PHP >= 5.5
363* Updated to use PSR-7
364  * Requires immutable messages, which basically means an event based system
365    owned by a request instance is no longer possible.
366  * Utilizing the [Guzzle PSR-7 package](https://github.com/guzzle/psr7).
367  * Removed the dependency on `guzzlehttp/streams`. These stream abstractions
368    are available in the `guzzlehttp/psr7` package under the `GuzzleHttp\Psr7`
369    namespace.
370* Added middleware and handler system
371  * Replaced the Guzzle event and subscriber system with a middleware system.
372  * No longer depends on RingPHP, but rather places the HTTP handlers directly
373    in Guzzle, operating on PSR-7 messages.
374  * Retry logic is now encapsulated in `GuzzleHttp\Middleware::retry`, which
375    means the `guzzlehttp/retry-subscriber` is now obsolete.
376  * Mocking responses is now handled using `GuzzleHttp\Handler\MockHandler`.
377* Asynchronous responses
378  * No longer supports the `future` request option to send an async request.
379    Instead, use one of the `*Async` methods of a client (e.g., `requestAsync`,
380    `getAsync`, etc.).
381  * Utilizing `GuzzleHttp\Promise` instead of React's promise library to avoid
382    recursion required by chaining and forwarding react promises. See
383    https://github.com/guzzle/promises
384  * Added `requestAsync` and `sendAsync` to send request asynchronously.
385  * Added magic methods for `getAsync()`, `postAsync()`, etc. to send requests
386    asynchronously.
387* Request options
388  * POST and form updates
389    * Added the `form_fields` and `form_files` request options.
390    * Removed the `GuzzleHttp\Post` namespace.
391    * The `body` request option no longer accepts an array for POST requests.
392  * The `exceptions` request option has been deprecated in favor of the
393    `http_errors` request options.
394  * The `save_to` request option has been deprecated in favor of `sink` request
395    option.
396* Clients no longer accept an array of URI template string and variables for
397  URI variables. You will need to expand URI templates before passing them
398  into a client constructor or request method.
399* Client methods `get()`, `post()`, `put()`, `patch()`, `options()`, etc. are
400  now magic methods that will send synchronous requests.
401* Replaced `Utils.php` with plain functions in `functions.php`.
402* Removed `GuzzleHttp\Collection`.
403* Removed `GuzzleHttp\BatchResults`. Batched pool results are now returned as
404  an array.
405* Removed `GuzzleHttp\Query`. Query string handling is now handled using an
406  associative array passed into the `query` request option. The query string
407  is serialized using PHP's `http_build_query`. If you need more control, you
408  can pass the query string in as a string.
409* `GuzzleHttp\QueryParser` has been replaced with the
410  `GuzzleHttp\Psr7\parse_query`.
411
412## 5.2.0 - 2015-01-27
413
414* Added `AppliesHeadersInterface` to make applying headers to a request based
415  on the body more generic and not specific to `PostBodyInterface`.
416* Reduced the number of stack frames needed to send requests.
417* Nested futures are now resolved in the client rather than the RequestFsm
418* Finishing state transitions is now handled in the RequestFsm rather than the
419  RingBridge.
420* Added a guard in the Pool class to not use recursion for request retries.
421
422## 5.1.0 - 2014-12-19
423
424* Pool class no longer uses recursion when a request is intercepted.
425* The size of a Pool can now be dynamically adjusted using a callback.
426  See https://github.com/guzzle/guzzle/pull/943.
427* Setting a request option to `null` when creating a request with a client will
428  ensure that the option is not set. This allows you to overwrite default
429  request options on a per-request basis.
430  See https://github.com/guzzle/guzzle/pull/937.
431* Added the ability to limit which protocols are allowed for redirects by
432  specifying a `protocols` array in the `allow_redirects` request option.
433* Nested futures due to retries are now resolved when waiting for synchronous
434  responses. See https://github.com/guzzle/guzzle/pull/947.
435* `"0"` is now an allowed URI path. See
436  https://github.com/guzzle/guzzle/pull/935.
437* `Query` no longer typehints on the `$query` argument in the constructor,
438  allowing for strings and arrays.
439* Exceptions thrown in the `end` event are now correctly wrapped with Guzzle
440  specific exceptions if necessary.
441
442## 5.0.3 - 2014-11-03
443
444This change updates query strings so that they are treated as un-encoded values
445by default where the value represents an un-encoded value to send over the
446wire. A Query object then encodes the value before sending over the wire. This
447means that even value query string values (e.g., ":") are url encoded. This
448makes the Query class match PHP's http_build_query function. However, if you
449want to send requests over the wire using valid query string characters that do
450not need to be encoded, then you can provide a string to Url::setQuery() and
451pass true as the second argument to specify that the query string is a raw
452string that should not be parsed or encoded (unless a call to getQuery() is
453subsequently made, forcing the query-string to be converted into a Query
454object).
455
456## 5.0.2 - 2014-10-30
457
458* Added a trailing `\r\n` to multipart/form-data payloads. See
459  https://github.com/guzzle/guzzle/pull/871
460* Added a `GuzzleHttp\Pool::send()` convenience method to match the docs.
461* Status codes are now returned as integers. See
462  https://github.com/guzzle/guzzle/issues/881
463* No longer overwriting an existing `application/x-www-form-urlencoded` header
464  when sending POST requests, allowing for customized headers. See
465  https://github.com/guzzle/guzzle/issues/877
466* Improved path URL serialization.
467
468  * No longer double percent-encoding characters in the path or query string if
469    they are already encoded.
470  * Now properly encoding the supplied path to a URL object, instead of only
471    encoding ' ' and '?'.
472  * Note: This has been changed in 5.0.3 to now encode query string values by
473    default unless the `rawString` argument is provided when setting the query
474    string on a URL: Now allowing many more characters to be present in the
475    query string without being percent encoded. See https://tools.ietf.org/html/rfc3986#appendix-A
476
477## 5.0.1 - 2014-10-16
478
479Bugfix release.
480
481* Fixed an issue where connection errors still returned response object in
482  error and end events event though the response is unusable. This has been
483  corrected so that a response is not returned in the `getResponse` method of
484  these events if the response did not complete. https://github.com/guzzle/guzzle/issues/867
485* Fixed an issue where transfer statistics were not being populated in the
486  RingBridge. https://github.com/guzzle/guzzle/issues/866
487
488## 5.0.0 - 2014-10-12
489
490Adding support for non-blocking responses and some minor API cleanup.
491
492### New Features
493
494* Added support for non-blocking responses based on `guzzlehttp/guzzle-ring`.
495* Added a public API for creating a default HTTP adapter.
496* Updated the redirect plugin to be non-blocking so that redirects are sent
497  concurrently. Other plugins like this can now be updated to be non-blocking.
498* Added a "progress" event so that you can get upload and download progress
499  events.
500* Added `GuzzleHttp\Pool` which implements FutureInterface and transfers
501  requests concurrently using a capped pool size as efficiently as possible.
502* Added `hasListeners()` to EmitterInterface.
503* Removed `GuzzleHttp\ClientInterface::sendAll` and marked
504  `GuzzleHttp\Client::sendAll` as deprecated (it's still there, just not the
505  recommended way).
506
507### Breaking changes
508
509The breaking changes in this release are relatively minor. The biggest thing to
510look out for is that request and response objects no longer implement fluent
511interfaces.
512
513* Removed the fluent interfaces (i.e., `return $this`) from requests,
514  responses, `GuzzleHttp\Collection`, `GuzzleHttp\Url`,
515  `GuzzleHttp\Query`, `GuzzleHttp\Post\PostBody`, and
516  `GuzzleHttp\Cookie\SetCookie`. This blog post provides a good outline of
517  why I did this: https://ocramius.github.io/blog/fluent-interfaces-are-evil/.
518  This also makes the Guzzle message interfaces compatible with the current
519  PSR-7 message proposal.
520* Removed "functions.php", so that Guzzle is truly PSR-4 compliant. Except
521  for the HTTP request functions from function.php, these functions are now
522  implemented in `GuzzleHttp\Utils` using camelCase. `GuzzleHttp\json_decode`
523  moved to `GuzzleHttp\Utils::jsonDecode`. `GuzzleHttp\get_path` moved to
524  `GuzzleHttp\Utils::getPath`. `GuzzleHttp\set_path` moved to
525  `GuzzleHttp\Utils::setPath`. `GuzzleHttp\batch` should now be
526  `GuzzleHttp\Pool::batch`, which returns an `objectStorage`. Using functions.php
527  caused problems for many users: they aren't PSR-4 compliant, require an
528  explicit include, and needed an if-guard to ensure that the functions are not
529  declared multiple times.
530* Rewrote adapter layer.
531    * Removing all classes from `GuzzleHttp\Adapter`, these are now
532      implemented as callables that are stored in `GuzzleHttp\Ring\Client`.
533    * Removed the concept of "parallel adapters". Sending requests serially or
534      concurrently is now handled using a single adapter.
535    * Moved `GuzzleHttp\Adapter\Transaction` to `GuzzleHttp\Transaction`. The
536      Transaction object now exposes the request, response, and client as public
537      properties. The getters and setters have been removed.
538* Removed the "headers" event. This event was only useful for changing the
539  body a response once the headers of the response were known. You can implement
540  a similar behavior in a number of ways. One example might be to use a
541  FnStream that has access to the transaction being sent. For example, when the
542  first byte is written, you could check if the response headers match your
543  expectations, and if so, change the actual stream body that is being
544  written to.
545* Removed the `asArray` parameter from
546  `GuzzleHttp\Message\MessageInterface::getHeader`. If you want to get a header
547  value as an array, then use the newly added `getHeaderAsArray()` method of
548  `MessageInterface`. This change makes the Guzzle interfaces compatible with
549  the PSR-7 interfaces.
550* `GuzzleHttp\Message\MessageFactory` no longer allows subclasses to add
551  custom request options using double-dispatch (this was an implementation
552  detail). Instead, you should now provide an associative array to the
553  constructor which is a mapping of the request option name mapping to a
554  function that applies the option value to a request.
555* Removed the concept of "throwImmediately" from exceptions and error events.
556  This control mechanism was used to stop a transfer of concurrent requests
557  from completing. This can now be handled by throwing the exception or by
558  cancelling a pool of requests or each outstanding future request individually.
559* Updated to "GuzzleHttp\Streams" 3.0.
560    * `GuzzleHttp\Stream\StreamInterface::getContents()` no longer accepts a
561      `maxLen` parameter. This update makes the Guzzle streams project
562      compatible with the current PSR-7 proposal.
563    * `GuzzleHttp\Stream\Stream::__construct`,
564      `GuzzleHttp\Stream\Stream::factory`, and
565      `GuzzleHttp\Stream\Utils::create` no longer accept a size in the second
566      argument. They now accept an associative array of options, including the
567      "size" key and "metadata" key which can be used to provide custom metadata.
568
569## 4.2.2 - 2014-09-08
570
571* Fixed a memory leak in the CurlAdapter when reusing cURL handles.
572* No longer using `request_fulluri` in stream adapter proxies.
573* Relative redirects are now based on the last response, not the first response.
574
575## 4.2.1 - 2014-08-19
576
577* Ensuring that the StreamAdapter does not always add a Content-Type header
578* Adding automated github releases with a phar and zip
579
580## 4.2.0 - 2014-08-17
581
582* Now merging in default options using a case-insensitive comparison.
583  Closes https://github.com/guzzle/guzzle/issues/767
584* Added the ability to automatically decode `Content-Encoding` response bodies
585  using the `decode_content` request option. This is set to `true` by default
586  to decode the response body if it comes over the wire with a
587  `Content-Encoding`. Set this value to `false` to disable decoding the
588  response content, and pass a string to provide a request `Accept-Encoding`
589  header and turn on automatic response decoding. This feature now allows you
590  to pass an `Accept-Encoding` header in the headers of a request but still
591  disable automatic response decoding.
592  Closes https://github.com/guzzle/guzzle/issues/764
593* Added the ability to throw an exception immediately when transferring
594  requests in parallel. Closes https://github.com/guzzle/guzzle/issues/760
595* Updating guzzlehttp/streams dependency to ~2.1
596* No longer utilizing the now deprecated namespaced methods from the stream
597  package.
598
599## 4.1.8 - 2014-08-14
600
601* Fixed an issue in the CurlFactory that caused setting the `stream=false`
602  request option to throw an exception.
603  See: https://github.com/guzzle/guzzle/issues/769
604* TransactionIterator now calls rewind on the inner iterator.
605  See: https://github.com/guzzle/guzzle/pull/765
606* You can now set the `Content-Type` header to `multipart/form-data`
607  when creating POST requests to force multipart bodies.
608  See https://github.com/guzzle/guzzle/issues/768
609
610## 4.1.7 - 2014-08-07
611
612* Fixed an error in the HistoryPlugin that caused the same request and response
613  to be logged multiple times when an HTTP protocol error occurs.
614* Ensuring that cURL does not add a default Content-Type when no Content-Type
615  has been supplied by the user. This prevents the adapter layer from modifying
616  the request that is sent over the wire after any listeners may have already
617  put the request in a desired state (e.g., signed the request).
618* Throwing an exception when you attempt to send requests that have the
619  "stream" set to true in parallel using the MultiAdapter.
620* Only calling curl_multi_select when there are active cURL handles. This was
621  previously changed and caused performance problems on some systems due to PHP
622  always selecting until the maximum select timeout.
623* Fixed a bug where multipart/form-data POST fields were not correctly
624  aggregated (e.g., values with "&").
625
626## 4.1.6 - 2014-08-03
627
628* Added helper methods to make it easier to represent messages as strings,
629  including getting the start line and getting headers as a string.
630
631## 4.1.5 - 2014-08-02
632
633* Automatically retrying cURL "Connection died, retrying a fresh connect"
634  errors when possible.
635* cURL implementation cleanup
636* Allowing multiple event subscriber listeners to be registered per event by
637  passing an array of arrays of listener configuration.
638
639## 4.1.4 - 2014-07-22
640
641* Fixed a bug that caused multi-part POST requests with more than one field to
642  serialize incorrectly.
643* Paths can now be set to "0"
644* `ResponseInterface::xml` now accepts a `libxml_options` option and added a
645  missing default argument that was required when parsing XML response bodies.
646* A `save_to` stream is now created lazily, which means that files are not
647  created on disk unless a request succeeds.
648
649## 4.1.3 - 2014-07-15
650
651* Various fixes to multipart/form-data POST uploads
652* Wrapping function.php in an if-statement to ensure Guzzle can be used
653  globally and in a Composer install
654* Fixed an issue with generating and merging in events to an event array
655* POST headers are only applied before sending a request to allow you to change
656  the query aggregator used before uploading
657* Added much more robust query string parsing
658* Fixed various parsing and normalization issues with URLs
659* Fixing an issue where multi-valued headers were not being utilized correctly
660  in the StreamAdapter
661
662## 4.1.2 - 2014-06-18
663
664* Added support for sending payloads with GET requests
665
666## 4.1.1 - 2014-06-08
667
668* Fixed an issue related to using custom message factory options in subclasses
669* Fixed an issue with nested form fields in a multi-part POST
670* Fixed an issue with using the `json` request option for POST requests
671* Added `ToArrayInterface` to `GuzzleHttp\Cookie\CookieJar`
672
673## 4.1.0 - 2014-05-27
674
675* Added a `json` request option to easily serialize JSON payloads.
676* Added a `GuzzleHttp\json_decode()` wrapper to safely parse JSON.
677* Added `setPort()` and `getPort()` to `GuzzleHttp\Message\RequestInterface`.
678* Added the ability to provide an emitter to a client in the client constructor.
679* Added the ability to persist a cookie session using $_SESSION.
680* Added a trait that can be used to add event listeners to an iterator.
681* Removed request method constants from RequestInterface.
682* Fixed warning when invalid request start-lines are received.
683* Updated MessageFactory to work with custom request option methods.
684* Updated cacert bundle to latest build.
685
6864.0.2 (2014-04-16)
687------------------
688

693
694* The HTTP status code of a response is now set as the exception code of
695  RequestException objects.
696* 303 redirects will now correctly switch from POST to GET requests.
697* The default parallel adapter of a client now correctly uses the MultiAdapter.
698* HasDataTrait now initializes the internal data array as an empty array so
699  that the toArray() method always returns an array.
700
701## 4.0.0 - 2014-03-29
702
703* For information on changes and upgrading, see:
704  https://github.com/guzzle/guzzle/blob/master/UPGRADING.md#3x-to-40
705* Added `GuzzleHttp\batch()` as a convenience function for sending requests in
706  parallel without needing to write asynchronous code.
707* Restructured how events are added to `GuzzleHttp\ClientInterface::sendAll()`.
708  You can now pass a callable or an array of associative arrays where each
709  associative array contains the "fn", "priority", and "once" keys.
710
711## 4.0.0.rc-2 - 2014-03-25
712
713* Removed `getConfig()` and `setConfig()` from clients to avoid confusion
714  around whether things like base_url, message_factory, etc. should be able to
715  be retrieved or modified.
716* Added `getDefaultOption()` and `setDefaultOption()` to ClientInterface
717* functions.php functions were renamed using snake_case to match PHP idioms
718* Added support for `HTTP_PROXY`, `HTTPS_PROXY`, and
719  `GUZZLE_CURL_SELECT_TIMEOUT` environment variables
720* Added the ability to specify custom `sendAll()` event priorities
721* Added the ability to specify custom stream context options to the stream
722  adapter.
723* Added a functions.php function for `get_path()` and `set_path()`
724* CurlAdapter and MultiAdapter now use a callable to generate curl resources
725* MockAdapter now properly reads a body and emits a `headers` event
726* Updated Url class to check if a scheme and host are set before adding ":"
727  and "//". This allows empty Url (e.g., "") to be serialized as "".
728* Parsing invalid XML no longer emits warnings
729* Curl classes now properly throw AdapterExceptions
730* Various performance optimizations
731* Streams are created with the faster `Stream\create()` function
732* Marked deprecation_proxy() as internal
733* Test server is now a collection of static methods on a class
734
735## 4.0.0-rc.1 - 2014-03-15
736
737* See https://github.com/guzzle/guzzle/blob/master/UPGRADING.md#3x-to-40
738
739## 3.8.1 - 2014-01-28
740
741* Bug: Always using GET requests when redirecting from a 303 response
742* Bug: CURLOPT_SSL_VERIFYHOST is now correctly set to false when setting `$certificateAuthority` to false in
743  `Guzzle\Http\ClientInterface::setSslVerification()`
744* Bug: RedirectPlugin now uses strict RFC 3986 compliance when combining a base URL with a relative URL
745* Bug: The body of a request can now be set to `"0"`
746* Sending PHP stream requests no longer forces `HTTP/1.0`
747* Adding more information to ExceptionCollection exceptions so that users have more context, including a stack trace of
748  each sub-exception
749* Updated the `$ref` attribute in service descriptions to merge over any existing parameters of a schema (rather than
750  clobbering everything).
751* Merging URLs will now use the query string object from the relative URL (thus allowing custom query aggregators)
752* Query strings are now parsed in a way that they do no convert empty keys with no value to have a dangling `=`.
753  For example `foo&bar=baz` is now correctly parsed and recognized as `foo&bar=baz` rather than `foo=&bar=baz`.
754* Now properly escaping the regular expression delimiter when matching Cookie domains.
755* Network access is now disabled when loading XML documents
756
757## 3.8.0 - 2013-12-05

778
779* Bug fix: 0 is now an allowed value in a description parameter that has a default value (#430)
780* Bug fix: SchemaFormatter now returns an integer when formatting to a Unix timestamp
781  (see https://github.com/aws/aws-sdk-php/issues/147)
782* Bug fix: Cleaned up and fixed URL dot segment removal to properly resolve internal dots
783* Minimum PHP version is now properly specified as 5.3.3 (up from 5.3.2) (#420)
784* Updated the bundled cacert.pem (#419)
785* OauthPlugin now supports adding authentication to headers or query string (#425)
786
787## 3.7.3 - 2013-09-08
788
789* Added the ability to get the exception associated with a request/command when using `MultiTransferException` and
790  `CommandTransferException`.
791* Setting `additionalParameters` of a response to false is now honored when parsing responses with a service description
792* Schemas are only injected into response models when explicitly configured.
793* No longer guessing Content-Type based on the path of a request. Content-Type is now only guessed based on the path of
794  an EntityBody.
795* Bug fix: ChunkedIterator can now properly chunk a \Traversable as well as an \Iterator.
796* Bug fix: FilterIterator now relies on `\Iterator` instead of `\Traversable`.
797* Bug fix: Gracefully handling malformed responses in RequestMediator::writeResponseBody()
798* Bug fix: Replaced call to canCache with canCacheRequest in the CallbackCanCacheStrategy of the CachePlugin
799* Bug fix: Visiting XML attributes first before visiting XML children when serializing requests
800* Bug fix: Properly parsing headers that contain commas contained in quotes
801* Bug fix: mimetype guessing based on a filename is now case-insensitive
802
803## 3.7.2 - 2013-08-02

833## 3.7.0 - 2013-06-10
834
835* See UPGRADING.md for more information on how to upgrade.
836* Requests now support the ability to specify an array of $options when creating a request to more easily modify a
837  request. You can pass a 'request.options' configuration setting to a client to apply default request options to
838  every request created by a client (e.g. default query string variables, headers, curl options, etc.).
839* Added a static facade class that allows you to use Guzzle with static methods and mount the class to `\Guzzle`.
840  See `Guzzle\Http\StaticClient::mount`.
841* Added `command.request_options` to `Guzzle\Service\Command\AbstractCommand` to pass request options to requests
842      created by a command (e.g. custom headers, query string variables, timeout settings, etc.).
843* Stream size in `Guzzle\Stream\PhpStreamRequestFactory` will now be set if Content-Length is returned in the
844  headers of a response
845* Added `Guzzle\Common\Collection::setPath($path, $value)` to set a value into an array using a nested key
846  (e.g. `$collection->setPath('foo/baz/bar', 'test'); echo $collection['foo']['bar']['bar'];`)
847* ServiceBuilders now support storing and retrieving arbitrary data
848* CachePlugin can now purge all resources for a given URI
849* CachePlugin can automatically purge matching cached items when a non-idempotent request is sent to a resource
850* CachePlugin now uses the Vary header to determine if a resource is a cache hit
851* `Guzzle\Http\Message\Response` now implements `\Serializable`
852* Added `Guzzle\Cache\CacheAdapterFactory::fromCache()` to more easily create cache adapters
853* `Guzzle\Service\ClientInterface::execute()` now accepts an array, single command, or Traversable
854* Fixed a bug in `Guzzle\Http\Message\Header\Link::addLink()`
855* Better handling of calculating the size of a stream in `Guzzle\Stream\Stream` using fstat() and caching the size
856* `Guzzle\Common\Exception\ExceptionCollection` now creates a more readable exception message
857* Fixing BC break: Added back the MonologLogAdapter implementation rather than extending from PsrLog so that older
858  Symfony users can still use the old version of Monolog.
859* Fixing BC break: Added the implementation back in for `Guzzle\Http\Message\AbstractMessage::getTokenizedHeader()`.
860  Now triggering an E_USER_DEPRECATED warning when used. Use `$message->getHeader()->parseParams()`.
861* Several performance improvements to `Guzzle\Common\Collection`
862* Added an `$options` argument to the end of the following methods of `Guzzle\Http\ClientInterface`:
863  createRequest, head, delete, put, patch, post, options, prepareRequest
864* Added an `$options` argument to the end of `Guzzle\Http\Message\Request\RequestFactoryInterface::createRequest()`
865* Added an `applyOptions()` method to `Guzzle\Http\Message\Request\RequestFactoryInterface`
866* Changed `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $body = null)` to
867  `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $options = array())`. You can still pass in a
868  resource, string, or EntityBody into the $options parameter to specify the download location of the response.
869* Changed `Guzzle\Common\Collection::__construct($data)` to no longer accepts a null value for `$data` but a
870  default `array()`
871* Added `Guzzle\Stream\StreamInterface::isRepeatable`
872* Removed `Guzzle\Http\ClientInterface::setDefaultHeaders(). Use
873  $client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`. or
874  $client->getConfig()->setPath('request.options/headers', array('header_name' => 'value'))`.
875* Removed `Guzzle\Http\ClientInterface::getDefaultHeaders(). Use $client->getConfig()->getPath('request.options/headers')`.

888  `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
889* Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use
890  `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
891* Marked `Guzzle\Http\Message\Request::setIsRedirect()` as deprecated. Use the HistoryPlugin instead.
892* Marked `Guzzle\Http\Message\Request::isRedirect()` as deprecated. Use the HistoryPlugin instead.
893* Marked `Guzzle\Cache\CacheAdapterFactory::factory()` as deprecated
894* Marked 'command.headers', 'command.response_body' and 'command.on_complete' as deprecated for AbstractCommand.
895  These will work through Guzzle 4.0
896* Marked 'request.params' for `Guzzle\Http\Client` as deprecated. Use [request.options][params].
897* Marked `Guzzle\Service\Client::enableMagicMethods()` as deprecated. Magic methods can no longer be disabled on a Guzzle\Service\Client.
898* Marked `Guzzle\Service\Client::getDefaultHeaders()` as deprecated. Use $client->getConfig()->getPath('request.options/headers')`.
899* Marked `Guzzle\Service\Client::setDefaultHeaders()` as deprecated. Use $client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`.
900* Marked `Guzzle\Parser\Url\UrlParser` as deprecated. Just use PHP's `parse_url()` and percent encode your UTF-8.
901* Marked `Guzzle\Common\Collection::inject()` as deprecated.
902* Marked `Guzzle\Plugin\CurlAuth\CurlAuthPlugin` as deprecated. Use `$client->getConfig()->setPath('request.options/auth', array('user', 'pass', 'Basic|Digest');`
903* CacheKeyProviderInterface and DefaultCacheKeyProvider are no longer used. All of this logic is handled in a
904  CacheStorageInterface. These two objects and interface will be removed in a future version.
905* Always setting X-cache headers on cached responses
906* Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin
907* `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface
908  $request, Response $response);`
909* `CacheStorageInterface::fetch($key)` has changed to `fetch(RequestInterface $request);`
910* `CacheStorageInterface::delete($key)` has changed to `delete(RequestInterface $request);`
911* Added `CacheStorageInterface::purge($url)`
912* `DefaultRevalidation::__construct(CacheKeyProviderInterface $cacheKey, CacheStorageInterface $cache, CachePlugin
913  $plugin)` has changed to `DefaultRevalidation::__construct(CacheStorageInterface $cache,
914  CanCacheStrategyInterface $canCache = null)`
915* Added `RevalidationInterface::shouldRevalidate(RequestInterface $request, Response $response)`
916
917## 3.6.0 - 2013-05-29
918
919* ServiceDescription now implements ToArrayInterface
920* Added command.hidden_params to blacklist certain headers from being treated as additionalParameters
921* Guzzle can now correctly parse incomplete URLs
922* Mixed casing of headers are now forced to be a single consistent casing across all values for that header.
923* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution
924* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader().
925* Specific header implementations can be created for complex headers. When a message creates a header, it uses a
926  HeaderFactory which can map specific headers to specific header classes. There is now a Link header and
927  CacheControl header implementation.
928* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate
929* Removed from interface: Guzzle\Http\ClientInterface::setCurlMulti()
930* Removed Guzzle\Http\Message\Request::receivedRequestHeader() and implemented this functionality in
931  Guzzle\Http\Curl\RequestMediator
932* Removed the optional $asString parameter from MessageInterface::getHeader(). Just cast the header to a string.
933* Removed the optional $tryChunkedTransfer option from Guzzle\Http\Message\EntityEnclosingRequestInterface
934* Removed the $asObjects argument from Guzzle\Http\Message\MessageInterface::getHeaders()
935* Removed Guzzle\Parser\ParserRegister::get(). Use getParser()
936* Removed Guzzle\Parser\ParserRegister::set(). Use registerParser().
937* All response header helper functions return a string rather than mixing Header objects and strings inconsistently
938* Removed cURL blacklist support. This is no longer necessary now that Expect, Accept, etc. are managed by Guzzle
939  directly via interfaces
940* Removed the injecting of a request object onto a response object. The methods to get and set a request still exist
941  but are a no-op until removed.
942* Most classes that used to require a `Guzzle\Service\Command\CommandInterface` typehint now request a
943  `Guzzle\Service\Command\ArrayCommandInterface`.
944* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response
945  on a request while the request is still being transferred
946* The ability to case-insensitively search for header values
947* Guzzle\Http\Message\Header::hasExactHeader
948* Guzzle\Http\Message\Header::raw. Use getAll()
949* Deprecated cache control specific methods on Guzzle\Http\Message\AbstractMessage. Use the CacheControl header object
950  instead.
951* `Guzzle\Service\Command\CommandInterface` now extends from ToArrayInterface and ArrayAccess
952* Added the ability to cast Model objects to a string to view debug information.
953
954## 3.5.0 - 2013-05-13
955
956* Bug: Fixed a regression so that request responses are parsed only once per oncomplete event rather than multiple times
957* Bug: Better cleanup of one-time events across the board (when an event is meant to fire once, it will now remove
958  itself from the EventDispatcher)
959* Bug: `Guzzle\Log\MessageFormatter` now properly writes "total_time" and "connect_time" values
960* Bug: Cloning an EntityEnclosingRequest now clones the EntityBody too
961* Bug: Fixed an undefined index error when parsing nested JSON responses with a sentAs parameter that reference a
962  non-existent key
963* Bug: All __call() method arguments are now required (helps with mocking frameworks)
964* Deprecating Response::getRequest() and now using a shallow clone of a request object to remove a circular reference
965  to help with refcount based garbage collection of resources created by sending a request
966* Deprecating ZF1 cache and log adapters. These will be removed in the next major version.
967* Deprecating `Response::getPreviousResponse()` (method signature still exists, but it's deprecated). Use the
968  HistoryPlugin for a history.
969* Added a `responseBody` alias for the `response_body` location
970* Refactored internals to no longer rely on Response::getRequest()
971* HistoryPlugin can now be cast to a string
972* HistoryPlugin now logs transactions rather than requests and responses to more accurately keep track of the requests
973  and responses that are sent over the wire
974* Added `getEffectiveUrl()` and `getRedirectCount()` to Response objects
975
976## 3.4.3 - 2013-04-30
977
978* Bug fix: Fixing bug introduced in 3.4.2 where redirect responses are duplicated on the final redirected response
979* Added a check to re-extract the temp cacert bundle from the phar before sending each request
980
981## 3.4.2 - 2013-04-29
982
983* Bug fix: Stream objects now work correctly with "a" and "a+" modes
984* Bug fix: Removing `Transfer-Encoding: chunked` header when a Content-Length is present
985* Bug fix: AsyncPlugin no longer forces HEAD requests
986* Bug fix: DateTime timezones are now properly handled when using the service description schema formatter
987* Bug fix: CachePlugin now properly handles stale-if-error directives when a request to the origin server fails
988* Setting a response on a request will write to the custom request body from the response body if one is specified
989* LogPlugin now writes to php://output when STDERR is undefined
990* Added the ability to set multiple POST files for the same key in a single call
991* application/x-www-form-urlencoded POSTs now use the utf-8 charset by default
992* Added the ability to queue CurlExceptions to the MockPlugin
993* Cleaned up how manual responses are queued on requests (removed "queued_response" and now using request.before_send)
994* Configuration loading now allows remote files
995
996## 3.4.1 - 2013-04-16
997
998* Large refactoring to how CurlMulti handles work. There is now a proxy that sits in front of a pool of CurlMulti
999  handles. This greatly simplifies the implementation, fixes a couple bugs, and provides a small performance boost.
1000* Exceptions are now properly grouped when sending requests in parallel
1001* Redirects are now properly aggregated when a multi transaction fails
1002* Redirects now set the response on the original object even in the event of a failure
1003* Bug fix: Model names are now properly set even when using $refs
1004* Added support for PHP 5.5's CurlFile to prevent warnings with the deprecated @ syntax
1005* Added support for oauth_callback in OAuth signatures
1006* Added support for oauth_verifier in OAuth signatures
1007* Added support to attempt to retrieve a command first literally, then ucfirst, the with inflection

1010
1011* Bug fix: URLs are now resolved correctly based on https://tools.ietf.org/html/rfc3986#section-5.2. #289
1012* Bug fix: Absolute URLs with a path in a service description will now properly override the base URL. #289
1013* Bug fix: Parsing a query string with a single PHP array value will now result in an array. #263
1014* Bug fix: Better normalization of the User-Agent header to prevent duplicate headers. #264.
1015* Bug fix: Added `number` type to service descriptions.
1016* Bug fix: empty parameters are removed from an OAuth signature
1017* Bug fix: Revalidating a cache entry prefers the Last-Modified over the Date header
1018* Bug fix: Fixed "array to string" error when validating a union of types in a service description
1019* Bug fix: Removed code that attempted to determine the size of a stream when data is written to the stream
1020* Bug fix: Not including an `oauth_token` if the value is null in the OauthPlugin.
1021* Bug fix: Now correctly aggregating successful requests and failed requests in CurlMulti when a redirect occurs.
1022* The new default CURLOPT_TIMEOUT setting has been increased to 150 seconds so that Guzzle works on poor connections.
1023* Added a feature to EntityEnclosingRequest::setBody() that will automatically set the Content-Type of the request if
1024  the Content-Type can be determined based on the entity body or the path of the request.
1025* Added the ability to overwrite configuration settings in a client when grabbing a throwaway client from a builder.
1026* Added support for a PSR-3 LogAdapter.
1027* Added a `command.after_prepare` event
1028* Added `oauth_callback` parameter to the OauthPlugin
1029* Added the ability to create a custom stream class when using a stream factory
1030* Added a CachingEntityBody decorator
1031* Added support for `additionalParameters` in service descriptions to define how custom parameters are serialized.
1032* The bundled SSL certificate is now provided in the phar file and extracted when running Guzzle from a phar.
1033* You can now send any EntityEnclosingRequest with POST fields or POST files and cURL will handle creating bodies
1034* POST requests using a custom entity body are now treated exactly like PUT requests but with a custom cURL method. This
1035  means that the redirect behavior of POST requests with custom bodies will not be the same as POST requests that use
1036  POST fields or files (the latter is only used when emulating a form POST in the browser).
1037* Lots of cleanup to CurlHandle::factory and RequestFactory::createRequest
1038
1039## 3.3.1 - 2013-03-10
1040
1041* Added the ability to create PHP streaming responses from HTTP requests
1042* Bug fix: Running any filters when parsing response headers with service descriptions
1043* Bug fix: OauthPlugin fixes to allow for multi-dimensional array signing, and sorting parameters before signing

1045  response location visitors.
1046* Bug fix: Removed the possibility of creating configuration files with circular dependencies
1047* RequestFactory::create() now uses the key of a POST file when setting the POST file name
1048* Added xmlAllowEmpty to serialize an XML body even if no XML specific parameters are set
1049

1052* A large number of performance optimizations have been made
1053* Bug fix: Added 'wb' as a valid write mode for streams
1054* Bug fix: `Guzzle\Http\Message\Response::json()` now allows scalar values to be returned
1055* Bug fix: Fixed bug in `Guzzle\Http\Message\Response` where wrapping quotes were stripped from `getEtag()`
1056* BC: Removed `Guzzle\Http\Utils` class
1057* BC: Setting a service description on a client will no longer modify the client's command factories.
1058* BC: Emitting IO events from a RequestMediator is now a parameter that must be set in a request's curl options using
1059  the 'emit_io' key. This was previously set under a request's parameters using 'curl.emit_io'
1060* BC: `Guzzle\Stream\Stream::getWrapper()` and `Guzzle\Stream\Stream::getSteamType()` are no longer converted to
1061  lowercase
1062* Operation parameter objects are now lazy loaded internally
1063* Added ErrorResponsePlugin that can throw errors for responses defined in service description operations' errorResponses
1064* Added support for instantiating responseType=class responseClass classes. Classes must implement
1065  `Guzzle\Service\Command\ResponseClassInterface`
1066* Added support for additionalProperties for top-level parameters in responseType=model responseClasses. These
1067  additional properties also support locations and can be used to parse JSON responses where the outermost part of the
1068  JSON is an array
1069* Added support for nested renaming of JSON models (rename sentAs to name)
1070* CachePlugin
1071    * Added support for stale-if-error so that the CachePlugin can now serve stale content from the cache on error
1072    * Debug headers can now added to cached response in the CachePlugin
1073
1074## 3.2.0 - 2013-02-14
1075
1076* CurlMulti is no longer reused globally. A new multi object is created per-client. This helps to isolate clients.
1077* URLs with no path no longer contain a "/" by default
1078* Guzzle\Http\QueryString does no longer manages the leading "?". This is now handled in Guzzle\Http\Url.
1079* BadResponseException no longer includes the full request and response message
1080* Adding setData() to Guzzle\Service\Description\ServiceDescriptionInterface
1081* Adding getResponseBody() to Guzzle\Http\Message\RequestInterface
1082* Various updates to classes to use ServiceDescriptionInterface type hints rather than ServiceDescription
1083* Header values can now be normalized into distinct values when multiple headers are combined with a comma separated list
1084* xmlEncoding can now be customized for the XML declaration of a XML service description operation
1085* Guzzle\Http\QueryString now uses Guzzle\Http\QueryAggregator\QueryAggregatorInterface objects to add custom value
1086  aggregation and no longer uses callbacks
1087* The URL encoding implementation of Guzzle\Http\QueryString can now be customized
1088* Bug fix: Filters were not always invoked for array service description parameters
1089* Bug fix: Redirects now use a target response body rather than a temporary response body
1090* Bug fix: The default exponential backoff BackoffPlugin was not giving when the request threshold was exceeded
1091* Bug fix: Guzzle now takes the first found value when grabbing Cache-Control directives
1092
1093## 3.1.2 - 2013-01-27
1094
1095* Refactored how operation responses are parsed. Visitors now include a before() method responsible for parsing the
1096  response body. For example, the XmlVisitor now parses the XML response into an array in the before() method.
1097* Fixed an issue where cURL would not automatically decompress responses when the Accept-Encoding header was sent
1098* CURLOPT_SSL_VERIFYHOST is never set to 1 because it is deprecated (see 5e0ff2ef20f839e19d1eeb298f90ba3598784444)
1099* Fixed a bug where redirect responses were not chained correctly using getPreviousResponse()
1100* Setting default headers on a client after setting the user-agent will not erase the user-agent setting
