We’re excited to announce the release of Milvus 2.6.2! This update introduces powerful new features, significant performance enhancements, and critical fixes that make the system more stable and production-ready. Highlights include partial field updates with upsert, JSON Shredding to accelerate dynamic field filtering, NGram indexing for faster LIKE queries, and more flexible schema evolution on existing collections. Built on community feedback, this release delivers a stronger foundation for real-world deployments, and we encourage all users to upgrade to take advantage of these improvements.
