We're excited to announce Milvus 2.5.14! This release delivers a range of performance and stability enhancements, including a separate chunk cache pool, auto-indexing for JSON fields, and local caching for BM25 segment statistics. This version also resolves several critical bugs, such as a thread explosion in the file watcher and potential panics in QueryCoord, to ensure a more robust and reliable system. We encourage you to upgrade to 2.5.14 to benefit from these latest updates!
