          New features and enhancements

          OneAgent OS module

          Host CPU is now measured properly when there are multiple processor groups on a Windows host.

          OpenTelemetry Java agent auto-instrumentation

          Dynatrace is now compatible with the OpenTelemetry Java auto-instrumentation agent.
