Announcing Couchbase Server 4.5.1

Couchbase Server version 4.5.1 has been released as the first maintenance update in the 4.5.x series, addressing over 145 stability, performance, and security issues across various services including the data service, query service, GSI, XDCR, and ForestDB. This release introduces several N1QL enhancements aimed at improving performance and easing the transition from RDBMS to NoSQL, such as the SUFFIXES function for faster string pattern matching, ARRAY_INTERSECTION for finding common items between arrays, and new capabilities for constructing objects and updating nested array elements. Additionally, the non-blocking streaming DISTINCT operator has been implemented to enhance query performance by emitting distinct values while minimizing memory consumption. Users are encouraged to provide feedback via Jira Issues, blog posts, and social media.
