Changes since 2.22.0

2.22.0

Summary

⚠️ If you're updating the MSI from version 2.13.0 or earlier and you are missing traces, you should restart the machine after updating. This issue has been fixed in 2.23.0.

Tracer

• Adds beta support for configuration DD_TRACE_OTEL_ENABLED. When set to true and automatic instrumentation is enabled for the application, you can use the OpenTelemetry API to generate Datadog spans. This setting will also allow you to get traces for libraries that we do not instrument yet if they do use System.Diagnostics to report their activity. This feature is currently in beta and we welcome feedback to improve it.

Continuous Profiler

• Fix deadlock found in 2.21 (Linux)
• Live heap profiling beta with DD_PROFILING_HEAP_ENABLED set to 1
