2.26.0

⛔ If you use the Continuous Profiler, please upgrade to v2.28.0 or greater. Release 2.26.0 introduced a native memory leak when using the Continuous Profiler.

⚠️ This release contains a known issue with DD_DBM_PROPAGATION_MODE. The issue is resolved in version 2.35.0.
Enabling DD_DBM_PROPAGATION_MODE may cause runtime errors in your application if you set the CommandType property on DbCommand to CommandType.StoredProcedure. If you suspect your application or a dependent library is using stored procedures, and you are currently using this release, don't enable DD_DBM_PROPAGATION_MODE until upgrading to 2.35.0+.

Summary

Adjustments on some previous tracer features, improve CI test skipping scenarios.
Profiler side, handle anonymous and inner named methods.
ASM side, suspicious request blocking is implemented through a consequent waf update.

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 feature is currently in beta and we welcome feedback to improve it.

Changes since 2.21.0

2.21.0

Summary

Warning We identified a bug in the .NET Runtime in .NET 5+ that can cause crashes in rare cases. You can mitigate the issue by setting DD_INTERNAL_WORKAROUND_77973_ENABLED=1. However, this disables tiered JIT in affected runtimes (.NET 5, .NET 6, .NET 7), which may have a significant impact on application throughput.

Note that setting this flag will have no effect or impact when set for unaffected runtimes. The root issue in the .NET runtime has been resolved and will be released in versions 6.0.13 and 7.0.2 of the runtime. No fix is available for .NET 5. Other .NET versions are not affected.

⛔ The Linux .NET profiler in this version can deadlock managed threads due to stackwalking while allocating memory. This is fixed in #3661. In the meantime, we recommend to either use the 2.20, either disable the profiler by setting the environment variable DD_PROFILING_ENABLED=0. The fix will be shipped in 2.22

⚠️ 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.
