The Neo4j-JDBC driver has been upgraded to work with recent Neo4j 3.3.x versions and Bolt driver 1.4.6, while work on Neo4j 3.4.x and drivers 1.6.x is in progress. The driver has been improved with the addition of support for in-memory databases, a debug feature, and TrustStrategy configuration options. It now implements the DataSource interface for JNDI lookups and has been updated to use the & separator instead of comma for URL parameters. The documentation has also been updated to explain how to use new features, including a Matlab example. Additionally, the driver can be used with various tools such as Squirrel SQL, Eclipse / BIRT, Jasper Reports, RapidMiner Studio, Pentaho Kettle, and Streamsets. The Neo4j-JDBC driver now supports Causal Clustering, allowing users to route reads and writes to the server with the correct role. It also features a routing context, bookmarks for causal consistency, and support for multiple bootstrap servers. The driver provides an Access Mode (READ, WRITE) feature, which enables transactions to be executed in either read or write mode.
