Neo4j 2.0 Comes with a New Browser and a Schema
Neo Technology has announced the availability of Neo4j 2.0, with a new graph browser, node labels, an optional schema and an improved Cypher.

The nodes can have labels now, and it is a way to mark nodes as belonging to a certain group. A node can have multiple labels.
