Neo4j 5.26 has been released as a Long-Term Support (LTS) version, offering critical patches and security updates until June 2028. This release marks the end of the Neo4j version 5.x series, while new features and performance enhancements will continue to be added to the 2025.x series. The 5.26 LTS release includes several key improvements, including parallel runtime for faster analytical query performance, concurrent execution of queries via independent sub-transactions, block format storage for reduced I/O operations, and improved security features such as dynamic labels, types, and properties. Additionally, Neo4j 5.26 enables vector similarity searches, bolstering recommendation engines and machine learning applications. It is recommended to plan an upgrade to either the 2025.x series or the 5.26 LTS to take advantage of cutting-edge features and prepare infrastructure for the future.
