+== 0.0.5 / 2009-11-17
+* Supports keeping lucene index in memory instead of on disk
+* Added support for lucene full text search
+* Fixed so neo4j runs on JRuby 1.1.5
+* Implemented support for reindex all instances of a node class. This is needed if the lucene index is kept in memory or if the index is changed.
+* Added ReferenceNode. All nodes now have a relationship from this reference node.
+* Lots of refactoring
+* Added the IMDB example. It shows how to create a neo database, lucene queries and node traversals.
+
+== 0.0.4 / 2009-10-23
+* First release to rubyforge

+=== Indexing and Property Types
+
+In order to use range querie on numbers the property types must be converted.
+This is done by using the :type optional parameter:
+
+  class Person
+    include Neo4j::NodeMixin
+    properties :name, :age
+    index :age, :type => Fixnum
+  end
+
+By using :type => Fixnum the age will be padded with '0's (lucene only support string comparsion).
+
+Example, if the :type => Fixnum was not specified then
+
+  p = Person.new {|n| n.age = 100 }
+  Person.find(:age => 0..8) # => [p]
+
 === Indexing and Quering Relationships
 
 The Neo4j::NodeMixin#index method can be used to index relationships to other classes.
