You can now run OpenSearch version 2.11 in Amazon OpenSearch Service. With OpenSearch 2.11, we have made several improvements to search, observability, security analytics, and OpenSearch Dashboards. This version includes features that were launched as part of open source OpenSearch versions 2.10 and 2.11. Some of the key improvements include introduction of hybrid query functionality which uses the normalization processors to improve search relevance by combining the relevance scores of lexical queries with natural language-based k-NN vector search queries, multimodal search that allows users to search image and text pairs like product catalog items, a new search comparison tool that lets you compare the results of two different search queries side by side in OpenSearch Dashboards and, introduction of sparse retrieval in addition to existing dense retrieval for semantic search applications.

With this release, Security Analytics includes three enhancements: support for custom log types to onboard user defined log types, a new workflow to simplify creation of threat detectors and alerts, and introduction of custom log categories for easier filtering and sorting. Other improvements include a new visual theme and a discover tool for a more user-friendly Dashboards environment and, a new IP2Geo processor, that allows users to retrieve the geographical location of an IPv4 or IPv6 address and add that information to incoming data during ingest or at a later time, if needed.

For information on upgrading to OpenSearch 2.11, please see our documentation. OpenSearch 2.11 is now available in Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD.
