2.32.0

⚠️ 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

• Trimmed apps support: You can now instrument trimmed apps by including the Datadog.Trace.Trimming nuget package to your project. This is a pre-release, do not hesitate to share feedback through Github issues.

• AWS SDK SNS is now supported by the tracer. Edit: We discovered an issue with the current implementation of AWS SDK SNS support. A fix for this will be included in the next tracer release. For more details see link to issue and link to PR.

Profiler

• Reduce CPU consumption on Linux
