🎉 Elastic Stack 8.9 released

:tada: What’s new in Elastic 8.9

This release provides faster search performance and increased SIEM capabilities along with a tech preview of Reciprocal Rank Fusion for hybrid search. Importantly, the beta release of the Elastic AI Assistant for Security is also included to increase the productivity of security teams using the power of generative AI.

Elastic Security includes the beta release of Elastic AI Assistant for Security, powered by ESRE™ to help accelerate analyst investigations. The 8.9 release also boasts the general availability of several new features, including enhanced rule management and tuning, advanced analytics for Lateral Movement Detection, an upload command for faster remediation response, and augmented onboarding via support for AWS CloudFormation.

Elastic Search (also known as Elastic Enterprise Search) showcases the tech preview of Reciprocal Rank Fusion (part of ESRE) for hybrid search for even more performant search experiences, new ServiceNow and Dropbox connectors, and more.

Elastic Observability contains the tech preview of Elastic AI Assistant for Observability, powered by ESRE, and the potential to achieve up to a 70% reduction in storage through the general availability of integrations leveraging Elastic TSDS.

As you know, all of Elastic’s out-of-the box solutions are built on one platform — the Elasticsearch platform. As a result, all users, regardless of use case, benefit from the following core enhancements:

  • The general availability of performance improvements to cross cluster search, faster search aggregations, and high cardinality aggregations

  • The general availability of semantic search using dense vector embeddings in a single API call or dense vector search acceleration

  • The general availability of ResponseOps (Kibana Alerting) and GAI-enhanced log rate spike explanations

  • Combining different search strategies with new components of ESRE like Elastic’s Learned Sparse Encoder with BM25 text ranking and applying additional relevance using Reciprocal Rank Fusion (RRF), now in Tech Preview
