config-schema: 1.1.0

1.1.0 (2026-06-03)

Features

• Add .NET 8+ support for System.Data.Odbc (#2948) (7ee9825)
• Add a new Distributed Tracing sampler, the TraceId Ratio-Based Sampler, which is based on the OpenTelemetry implementation. This sampler makes its sampling decision using the TraceId (a random GUID) and a configured sampling ratio (a target percentage of traces to be sampled). For more information, see the OpenTelemetry specification. (#3211) (63ca603)
• Allow incoming W3C traceparent sampled flag to influence .NET agent sampling decision. (#3100) (6047bda)
• Allow users to configure process names that should not be instrumented (#3387) (8dedf32)
• The .NET Hybrid Agent provides a future-proof observability solution with integrated support for OpenTelemetry Tracing and Metrics APIs. OpenTelemetry Logs will continue to be supported through the existing Microsoft.Extensions.Logging integration. This release delivers critical OpenTelemetry features including Span Links, Events on Spans, and unified sampling algorithms. It is designed to bridge the gap for .NET teams looking to adopt OpenTelemetry standards while maintaining backwards compatibility with their existing New Relic dashboards. (72a0414)
