+CHANGELOG
+=========
+
+2.7.0
+-----
+
+ * added support for serialization and deserialization groups including
+   annotations, XML and YAML mapping.
+ * added `AbstractNormalizer` to factorise code and ease normalizers development
+ * added circular references handling for `PropertyNormalizer`
+ * added support for a context key called `object_to_populate` in `AbstractNormalizer`
+   to reuse existing objects in the deserialization process
+ * added `NameConverterInterface` and `CamelCaseToSnakeCaseNameConverter`
+ * [DEPRECATION] `GetSetMethodNormalizer::setCamelizedAttributes()` and
+   `PropertyNormalizer::setCamelizedAttributes()` are replaced by
+   `CamelCaseToSnakeCaseNameConverter`
+ * [DEPRECATION] the `Exception` interface has been renamed to `ExceptionInterface`
+ * added `ObjectNormalizer` leveraging the `PropertyAccess` component to normalize
+   objects containing both properties and getters / setters / issers / hassers methods.
+
+2.6.0
+-----
+
+ * added a new serializer: `PropertyNormalizer`. Like `GetSetMethodNormalizer`,
+   this normalizer will map an object's properties to an array.
+ * added circular references handling for `GetSetMethodNormalizer`
+
+2.5.0
+-----
+
+ * added support for `is.*` getters in `GetSetMethodNormalizer`
+
+2.4.0
+-----
+
+ * added `$context` support for XMLEncoder.
+ * [DEPRECATION] JsonEncode and JsonDecode where modified to throw
+   an exception if error found. No need for get*Error() functions
+
+2.3.0
+-----
+
+ * added `GetSetMethodNormalizer::setCamelizedAttributes` to allow calling
+   camel cased methods for underscored properties
+
+2.2.0
+-----
+
+ * [BC BREAK] All Serializer, Normalizer and Encoder interfaces have been
+   modified to include an optional `$context` array parameter.
+ * The XML Root name can now be configured with the `xml_root_name`
+   parameter in the context option to the `XmlEncoder`.
+ * Options to `json_encode` and `json_decode` can be passed through
+   the context options of `JsonEncode` and `JsonDecode` encoder/decoders.
+
+2.1.0
+-----
+
+ * added DecoderInterface::supportsDecoding(),
+   EncoderInterface::supportsEncoding()
+ * removed NormalizableInterface::denormalize(),
+   NormalizerInterface::denormalize(),
+   NormalizerInterface::supportsDenormalization()
+ * removed normalize() denormalize() encode() decode() supportsSerialization()
+   supportsDeserialization() supportsEncoding() supportsDecoding()
+   getEncoder() from SerializerInterface
+ * Serializer now implements NormalizerInterface, DenormalizerInterface,
+   EncoderInterface, DecoderInterface in addition to SerializerInterface
+ * added DenormalizableInterface and DenormalizerInterface
+ * [BC BREAK] changed `GetSetMethodNormalizer`'s key names from all lowercased
+   to camelCased (e.g. `mypropertyvalue` to `myPropertyValue`)
+ * [BC BREAK] convert the `item` XML tag to an array
+
+    ``` xml
+    <?xml version="1.0"?>
+    <response>
+        <item><title><![CDATA[title1]]></title></item><item><title><![CDATA[title2]]></title></item>
+    </response>
+    ```
+
+    Before:
+
+        Array()
+
+    After:
+
+        Array(
+            [item] => Array(
+                [0] => Array(
+                    [title] => title1
+                )
+                [1] => Array(
+                    [title] => title2
+                )
+            )
+        )
