+CHANGELOG
+=========
+
+2.7.0
+------
+
+ * `UnexpectedTypeException` now expects three constructor arguments: The invalid property value,
+   the `PropertyPathInterface` object and the current index of the property path.
+
+2.5.0
+------
+
+ * allowed non alpha numeric characters in second level and deeper object properties names
+ * [BC BREAK] when accessing an index on an object that does not implement
+   ArrayAccess, a NoSuchIndexException is now thrown instead of the
+   semantically wrong NoSuchPropertyException
+ * [BC BREAK] added isReadable() and isWritable() to PropertyAccessorInterface
+
+2.3.0
+------
+
+ * added PropertyAccessorBuilder, to enable or disable the support of "__call"
+ * added support for "__call" in the PropertyAccessor (disabled by default)
+ * [BC BREAK] changed PropertyAccessor to continue its search for a property or
+   method even if a non-public match was found. Before, a PropertyAccessDeniedException
+   was thrown in this case. Class PropertyAccessDeniedException was removed
+   now.
+ * deprecated PropertyAccess::getPropertyAccessor
+ * added PropertyAccess::createPropertyAccessor and PropertyAccess::createPropertyAccessorBuilder
