+### Rock and Fluid Samples (RAFS) DDMS - Generally Available
+The Rock and Fluid Samples (RAFS) DDMS is now generally available in Azure Data Manager for Energy. RAFS provides a standardized, scalable foundation for storing, querying, and analyzing geological and engineering sample data from subsurface and surface locations. These insights are essential for key energy workflows, including reservoir modeling, drilling planning, and facility design.
+
+To learn more about RAFS DDMS, see the official documentation: [Rock and Fluid Samples (RAFS) DDMS APIs](tutorial-rock-and-fluid-samples-ddms.md).
+
+### Dangerous Query Rate Limit Enforcement
+To strengthen service resiliency, Azure Data Manager for Energy now applies targeted ratelimiting to a narrow class of highrisk wildcard queries that can negatively impact cluster performance. This guardrail affects only queries using the fully unbounded pattern \*\:\*\:\*\:\* in the kind field of requests sent to /api/search/v2/query and /api/search/v2/query_with_cursor. Typical ingestion, search, and operational workloads are not impacted. 
+
+When a query is ratelimited, clients receive an HTTP 429 – Too Many Requests responses. The response body provides a clear explanation and guidance. The enforcement logic uses a conservative default configuration of 2 burst tokens, a refill rate of 1 token every 5 seconds, and an effective allowance of approximately 12 such wildcard queries per minute. 
+
+Users can avoid ratelimit conditions by issuing bounded queries with explicit kind values rather than relying on fully open wildcard patterns.
