The Neo4j team has announced several significant updates in the latest release, including improvements to high availability (HA) support, allowing for large datasets and easier cluster management. The new release also enhances remote server performance, introduces automatic indexing, and refines the Traversal API. Additionally, the Neo4j shell has been improved with better exception messages and an "eval" app for evaluating arbitrary JavaScript code. Furthermore, the team has moved their product source repositories from Subversion to GitHub, aiming to foster community involvement and feedback. The release also requires Java 6, which is expected to be a non-issue for most users.
