The text discusses the evolution of Neo4j, a popular graph database management system. In April 2016, Neo4j introduced its binary protocol named Bolt, which provided improved performance and efficiency for developers. The Bolt protocol was supported by various programming languages, including Java, Python, JavaScript, and .Net. Several contributors developed drivers for Bolt, including those in the Go, Elixir, and Haskell communities. In October 2016, Neo4j released its third beta version of Neo4j 3.1, which introduced new APIs to support Causal Clustering and Smart Client Routing. These features improved concurrent operations and session reuse, making it easier for developers to work with the graph database. The text also highlights the growing community of contributors who have developed Neo4j drivers, including those in the Ruby and PHP communities.
