+
+      "Object" form shall mean any form resulting from mechanical

+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including

+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+
+## 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.
+* Added `setPort()` and `getPort()` to `GuzzleHttp\Message\RequestInterface`.
+* Added the ability to provide an emitter to a client in the client constructor.
+* Added the ability to persist a cookie session using $_SESSION.
+* Added a trait that can be used to add event listeners to an iterator.
+* Removed request method constants from RequestInterface.
+* Fixed warning when invalid request start-lines are received.
+* Updated MessageFactory to work with custom request option methods.
+* Updated cacert bundle to latest build.
+
+4.0.2 (2014-04-16)
+------------------
+
+* Proxy requests using the StreamAdapter now properly use request_fulluri (#632)
+* Added the ability to set scalars as POST fields (#628)
+
+## 4.0.1 - 2014-04-04
+
+* The HTTP status code of a response is now set as the exception code of
+  RequestException objects.
+* 303 redirects will now correctly switch from POST to GET requests.
+* The default parallel adapter of a client now correctly uses the MultiAdapter.

+  that the toArray() method always returns an array.
+
+## 4.0.0 - 2014-03-29
+
+* For more information on the 4.0 transition, see:
+  http://mtdowling.com/blog/2014/03/15/guzzle-4-rc/

+* Added `GuzzleHttp\batch()` as a convenience function for sending requests in
+  parallel without needing to write asynchronous code.
+* Restructured how events are added to `GuzzleHttp\ClientInterface::sendAll()`.

+  associative array contains the "fn", "priority", and "once" keys.
+
+## 4.0.0.rc-2 - 2014-03-25
+
+* Removed `getConfig()` and `setConfig()` from clients to avoid confusion
+  around whether things like base_url, message_factory, etc. should be able to
+  be retrieved or modified.
+* Added `getDefaultOption()` and `setDefaultOption()` to ClientInterface
+* functions.php functions were renamed using snake_case to match PHP idioms
+* Added support for `HTTP_PROXY`, `HTTPS_PROXY`, and
+  `GUZZLE_CURL_SELECT_TIMEOUT` environment variables
+* Added the ability to specify custom `sendAll()` event priorities

+  clobbering everything).
+* Merging URLs will now use the query string object from the relative URL (thus allowing custom query aggregators)
+* Query strings are now parsed in a way that they do no convert empty keys with no value to have a dangling `=`.
+  For example `foo&bar=baz` is now correctly parsed and recognized as `foo&bar=baz` rather than `foo=&bar=baz`.
+* Now properly escaping the regular expression delimiter when matching Cookie domains.
+* Network access is now disabled when loading XML documents

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

+* Removed `Guzzle\Http\Message\RequestInterface::isRedirect`
+* Made `Guzzle\Http\Client::expandTemplate` and `getUriTemplate` protected methods.
+* You can now enable E_USER_DEPRECATED warnings to see if you are using a deprecated method by setting
+  `Guzzle\Common\Version::$emitWarnings` to true.
+* Marked `Guzzle\Http\Message\Request::isResponseBodyRepeatable()` as deprecated. Use
+      `$request->getResponseBody()->isRepeatable()` instead.

+  `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 'command.headers', 'command.response_body' and 'command.on_complete' as deprecated for AbstractCommand.
+  These will work through Guzzle 4.0
+* Marked 'request.params' for `Guzzle\Http\Client` as deprecated. Use [request.options][params].
+* Marked `Guzzle\Service\Client::enableMagicMethods()` as deprecated. Magic methods can no longer be disabled on a Guzzle\Service\Client.
+* Marked `Guzzle\Service\Client::getDefaultHeaders()` as deprecated. Use $client->getConfig()->getPath('request.options/headers')`.
+* Marked `Guzzle\Service\Client::setDefaultHeaders()` as deprecated. Use $client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`.
+* Marked `Guzzle\Parser\Url\UrlParser` as deprecated. Just use PHP's `parse_url()` and percent encode your UTF-8.
+* Marked `Guzzle\Common\Collection::inject()` as deprecated.
+* Marked `Guzzle\Plugin\CurlAuth\CurlAuthPlugin` as deprecated. Use `$client->getConfig()->setPath('request.options/auth', array('user', 'pass', 'Basic|Digest');`
+* CacheKeyProviderInterface and DefaultCacheKeyProvider are no longer used. All of this logic is handled in a
+  CacheStorageInterface. These two objects and interface will be removed in a future version.
+* Always setting X-cache headers on cached responses
+* Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin
+* `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface
+  $request, Response $response);`
+* `CacheStorageInterface::fetch($key)` has changed to `fetch(RequestInterface $request);`
+* `CacheStorageInterface::delete($key)` has changed to `delete(RequestInterface $request);`

+  $plugin)` has changed to `DefaultRevalidation::__construct(CacheStorageInterface $cache,
+  CanCacheStrategyInterface $canCache = null)`
+* Added `RevalidationInterface::shouldRevalidate(RequestInterface $request, Response $response)`
+
+## 3.6.0 - 2013-05-29
+
+* ServiceDescription now implements ToArrayInterface
+* Added command.hidden_params to blacklist certain headers from being treated as additionalParameters
+* Guzzle can now correctly parse incomplete URLs
+* Mixed casing of headers are now forced to be a single consistent casing across all values for that header.
+* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution
+* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader().
+* Specific header implementations can be created for complex headers. When a message creates a header, it uses a
+  HeaderFactory which can map specific headers to specific header classes. There is now a Link header and
+  CacheControl header implementation.
+* 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 Guzzle\Parser\ParserRegister::set(). Use registerParser().
+* 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
+* 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.
+* `Guzzle\Service\Command\CommandInterface` now extends from ToArrayInterface and ArrayAccess
+* Added the ability to cast Model objects to a string to view debug information.
+

+
+* Bug: Fixed a regression so that request responses are parsed only once per oncomplete event rather than multiple times
+* Bug: Better cleanup of one-time events across the board (when an event is meant to fire once, it will now remove
+  itself from the EventDispatcher)
+* Bug: `Guzzle\Log\MessageFormatter` now properly writes "total_time" and "connect_time" values
+* Bug: Cloning an EntityEnclosingRequest now clones the EntityBody too
+* Bug: Fixed an undefined index error when parsing nested JSON responses with a sentAs parameter that reference a
+  non-existent key
+* Bug: All __call() method arguments are now required (helps with mocking frameworks)
+* 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
+  and responses that are sent over the wire

+* Configuration loading now allows remote files
+
+## 3.4.1 - 2013-04-16
+
+* Large refactoring to how CurlMulti handles work. There is now a proxy that sits in front of a pool of CurlMulti
+  handles. This greatly simplifies the implementation, fixes a couple bugs, and provides a small performance boost.
+* Exceptions are now properly grouped when sending requests in parallel
+* Redirects are now properly aggregated when a multi transaction fails
+* Redirects now set the response on the original object even in the event of a failure
+* Bug fix: Model names are now properly set even when using $refs

+* The new default CURLOPT_TIMEOUT setting has been increased to 150 seconds so that Guzzle works on poor connections.
+* Added a feature to EntityEnclosingRequest::setBody() that will automatically set the Content-Type of the request if
+  the Content-Type can be determined based on the entity body or the path of the request.
+* Added the ability to overwrite configuration settings in a client when grabbing a throwaway client from a builder.
+* Added support for a PSR-3 LogAdapter.
+* Added a `command.after_prepare` event

+* 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
+  POST fields or files (the latter is only used when emulating a form POST in the browser).
+* 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
+* Added ErrorResponsePlugin that can throw errors for responses defined in service description operations' errorResponses
+* Added support for instantiating responseType=class responseClass classes. Classes must implement
+  `Guzzle\Service\Command\ResponseClassInterface`

+* CachePlugin
+    * Added support for stale-if-error so that the CachePlugin can now serve stale content from the cache on error
+    * 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/repos/guzzle/guzzle');
+echo $res->getStatusCode();
+// 200
+echo $res->getHeaderLine('content-type');
+// 'application/json; charset=utf8'
+echo $res->getBody();
+// '{"id": 1420053, "name": "guzzle", ...}'
+
+// Send an asynchronous request.
+$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;
+    }
+```
+
+### Convert XML Service Descriptions to JSON
+
+**Before**
+
+```xml
+<?xml version="1.0" encoding="UTF-8"?>
+<client>
+    <commands>
+        <!-- Groups -->
+        <command name="list_groups" method="GET" uri="groups.json">

+Namespace is now `Guzzle\Plugin`. Many other changes occur within this namespace and are detailed in their own sections below.
+
+### Guzzle\Http\Plugin\LogPlugin and Guzzle\Common\Log
+
+Now `Guzzle\Plugin\Log\LogPlugin` and `Guzzle\Log` respectively.
+
+**Before**

+```
+
+### Guzzle\Http\Plugin\CurlAuthPlugin
+
+Now `Guzzle\Plugin\CurlAuth\CurlAuthPlugin`.
+
+### Guzzle\Http\Plugin\ExponentialBackoffPlugin
+
+Now `Guzzle\Plugin\Backoff\BackoffPlugin`, and other changes.
+
+**Before**
+
+```php
+use Guzzle\Http\Plugin\ExponentialBackoffPlugin;
+
+$backoffPlugin = new ExponentialBackoffPlugin($maxRetries, array_merge(
+        ExponentialBackoffPlugin::getDefaultFailureCodes(), array(429)

+
+**After**

+```php
+use Guzzle\Plugin\Backoff\BackoffPlugin;
+use Guzzle\Plugin\Backoff\HttpBackoffStrategy;
+
+// Use convenient factory method instead -- see implementation for ideas of what
+// you can do with chaining backoff strategies

+        HttpBackoffStrategy::getDefaultFailureCodes(), array(429)
+    ));

+```
+
+### Known Issues
+
+#### [BUG] Accept-Encoding header behavior changed unintentionally.
+
+(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.
