+[3.3.1](https://github.com/opensearch-project/opensearch-build/blob/main/release-notes/opensearch-release-notes-3.3.1.md) | Fixes backward compatibility handling of date fields while maintaining performance optimizations. The `skip_list` parameter is now automatically set to `true` for new `@timestamp` fields created since 3.3.0, while preserving `skip_list=false` for existing indexes with `@timestamp` or index sort date fields. This approach ensures date histogram aggregation performance benefits for new indexes while maintaining compatibility with existing workloads. For a full list of release highlights, see the [Release Notes](https://github.com/opensearch-project/opensearch-build/blob/main/release-notes/opensearch-release-notes-3.3.1.md). | 21 October 2025
 [3.3.0](https://github.com/opensearch-project/opensearch-build/blob/main/release-notes/opensearch-release-notes-3.3.0.md) | Introduces redesigned Discover interface with log analytics and distributed tracing capabilities, and Apache Calcite as default PPL query engine with expanded functions. Makes agentic search and agentic memory APIs generally available for AI applications. Implements Seismic algorithm for neural sparse search performance improvements and processor chains for data transformation pipelines. Expands gRPC support for additional query types and adds experimental streaming with Apache Arrow Flight. Includes workload management enhancements with rule-based auto-tagging and query monitoring capabilities. For a full list of release highlights, see the [Release Notes](https://github.com/opensearch-project/opensearch-build/blob/main/release-notes/opensearch-release-notes-3.3.0.md). | 14 October 2025

Introduces derived source, updates workload management, semantic field, and star tree functionality. Adds experimental Agentic Memory APIs and Job Scheduler APIs. For a full list of release highlights, see the [Release Notes](https://github.com/opensearch-project/opensearch-build/blob/main/release-notes/opensearch-release-notes-3.2.0.md). | 19 August 2025
 [3.1.0](https://github.com/opensearch-project/opensearch-build/blob/main/release-notes/opensearch-release-notes-3.1.0.md) | Makes GPU acceleration for vector index builds generally available. Introduces memory-optimized search for Faiss indexes using Lucene HNSW, semantic field type for streamlined semantic search, and Search Relevance Workbench for search quality optimization. Makes star-tree indexes generally available with support for comprehensive query types. Enhances observability with ML Commons metrics integration, custom index support for OpenTelemetry data, and new PPL commands for JSON manipulation. Improves agent management with Update Agent API and persistent MCP tools. Includes security enhancements with immutable user objects and new resource sharing framework. For a full list of release highlights, see the [Release Notes](https://github.com/opensearch-project/opensearch-build/blob/main/release-notes/opensearch-release-notes-3.1.0.md). | 24 June 2025
