This release of Neo4j features refinements to the Bolt driver API, as well as a range of fixes, improvements and small additions. A new example, known as the Reindeer Graph, is introduced, which models a team of reindeer arranged in pairs except for the lead, all pulling a sleigh. The graph can be created using Java code with Bolt to connect to Neo4j running on localhost. The code exercises the graph by querying for the strongest pair of reindeer and adds a new reindeer named "Bolt" to the team. Notable changes include an upgrade to Lucene 5, support for upgrading databases with older Lucene versions, and improvements to Bolt TCP, TLS, WebSocket, and Secure WebSocket. The release is part of Neo4j's Early Access Program and invites users to provide feedback through various channels.
