+Version 0.9.1-dev
+-----------------
+
+* Add ability to add attributes to nodes:
+
+  It is now possible to add attributes to a node using `$node->setAttribute('name', 'value')` and to retrieve them using
+  `$node->getAttribute('name' [, 'default'])`. Additionally the existance of an attribute can be checked with
+  `$node->hasAttribute('name')` and all attributes can be returned using `$node->getAttributes()`.
+
+* Add code generation features: Builders and templates.
+
+  For more infos, see the [code generation documentation][1].
+
+* [BC] Don't traverse nodes merged by another visitor:
+
+  If a NodeVisitor returns an array of nodes to merge, these will no longer be traversed by all other visitors. This
+  behavior only caused problems.
+
+* Fix line numbers for some list structures
+* Fix XML unserialization of empty nodes
+* Fix parsing of integers that overflow into floats
+* Fix emulation of NOWDOC and binary floats
+
+Version 0.9.0 (05.01.2012)
