[2016-08-29] Version 5.1.1
--------------------------
Changes the way that `uri`s are constructed to make sure that they are always
`rawurlencode()`d by the `twilio-php` library

Updates the output of the unit tests on failure introducing a new method,
`assertRequest()`, that will output a friendlier error message when a request is
missing in the `Holodeck` network mock.

[2016-08-19] Version 5.1.0
--------------------------
Optional arguments are handled in the `twilio-php` by accepting an associative
array of optional keys and values to pass to the API.  This makes it easy to
support all the optional parameters, but lessens developer ergonomics, since it
doesn't provide any inline documentation or autocomplete for optional arguments.

This change introduces new Options builders that support 2 new ways for
specifying optional arguments that provide better usability.

```php
<?php

use Twilio\Values;
use Twilio\Rest\Client;
use Twilio\Rest\Api\V2010\Account\CallOptions;

$client = new Client();

// Original Way (5.0.x)
$client->calls->create(
    '+14155551234',
    '+14155557890',
    array(
        'applicationSid' => 'AP123',
        'method' => 'POST',
    )
);

// Options Factory
$client->calls->create(
    '+14155551234',
    '+14155557890',
    CallOptions::create(
        Values::NONE,
        'AP123',
        'POST'
    )
);

// Options Builder
$client->calls->create(
    '+14155551234',
    '+14155557890',
    CallOptions::create()->setApplicationSid('AP123')
                         ->setMethod('POST')
);
```

The `Options Factory` provides fully documented optional arguments for every
optional argument supported by the Resource's Action.  This is a fast way to
handle endpoints that have a few optional arguments.

The `Options Builder` provides fully documented setters for every optional
arguments, this is great for actions that support a large number of optional
arguments, so that you don't need to provided tons of default values.

-------------

  new functionality.

Version 3.5.1
-------------

Released on July 2, 2012

- Fix an issue introduced in the 3.5.0 release that would cause a second HTTP
request for an instance resource [to request an incorrect URI][issue-71].

[issue-71]: https://github.com/twilio/twilio-php/pull/71

Version 3.5.0
-------------

Released on June 30, 2012

- Support paging through resources using the `next_page_uri` parameter instead
of manually constructing parameters using the `Page` and `PageSize` parameters.
Specifically, this allows the library to use the `AfterSid` parameter, which
leads to improved performance when paging deep into your resource list.

This involved a major refactor of the library. The documented interface to
twilio-php will not change. However, some undocumented public methods are no
longer supported. Specifically, the following classes are no longer available:

- `Services/Twilio/ArrayDataProxy.php`
- `Services/Twilio/CachingDataProxy.php`
- `Services/Twilio/DataProxy.php`

In addition, the following public methods have been removed:

- `setProxy`, in `Services/Twilio/InstanceResource.php`
- `getSchema`, in `Services/Twilio/ListResource.php`,
    `Services/Twilio/Rest/AvailablePhoneNumbers.php`,
    `Services/Twilio/Rest/SMSMessages.php`

- `retrieveData`, in `Services/Twilio/Resource.php`
- `deleteData`, in `Services/Twilio/Resource.php`
- `addSubresource`, in `Services/Twilio/Resource.php`

Please check your own code for compatibility before upgrading.

Version 3.3.2
-------------

Released on May 3, 2012

- If you pass booleans in as TwiML (ex transcribe="true"), convert them to
  the strings "true" and "false" instead of outputting the incorrect values
  1 and "".

Version 3.3.1
-------------

Released on May 1, 2012

- Use the 'Accept-Charset' header to specify we want to receive UTF-8 encoded
data from the Twilio API. Remove unused XML parsing logic, as the library never
requests XML data.

Version 3.2.4
-------------

Released on March 14, 2012

- If no version is passed to the Services_Twilio constructor, the library will
  default to the most recent API version.
