zend-serializer 2.9.0

Added
-----

- [#37](#37) adds support to the `PhpSerialize` adapter to allow it to support the
  PHP 7 `$options` parameter of `unserialize`, and, specifically, the `allowed_classes` parameter.
  A new options class, `PhpSerializeOptions`, now allows setting the `unserialize_class_whitelist`
  option, which may be one of `true` (any class may be unserialized; current behavior), `false`
  (no class may be unserialized), or an `array` of class names that are explicitly allowed to
  be unserialized. An instance of this class may now be passed to the `PhpSerialize` constructor
  in order to set the intended/expected behavior.
