The latest version of Spring Data Aerospike, version 5.0.0, introduces several new features and enhancements, including updated parameters in application.properties, a custom queries mechanism, applying filter expression as secondary index fallback, and limiting the minimal supported Aerospike Server version to 6.1.0.0. The new custom queries API allows for more flexibility and readability in creating complex queries, while the filter expression fallback mechanism provides an alternative query method when secondary indexes are incompatible. Additionally, users are encouraged to upgrade their Aerospike Server version to ensure compatibility with the latest features and improvements. A migration guide is available to help users transition from Spring Data Aerospike 4.8.0 to 5.0.0.
