Version 1.37.0

This release targets the OpenTelemetry SDK 1.40.0.

AWS resources

• Add ECS cluster detection (#1354)

Baggage processor

• Add config support (#1330)

Inferred spans - New 🌟

An OpenTelemetry extension for generating spans via profiling instead of instrumentation. This extension enhances traces by running async-profiler in wall-clock profiling mode whenever there is an active sampled OpenTelemetry span.

The resulting profiling data is analyzed afterward and spans are "inferred". This means there is a delay between the regular and the inferred spans being visible in your OpenTelemetry backend/UI.

JFR connection

• Fix for using diagnostic command to start a recording (#1352)

JMX metrics

• Support both a script and target systems (#1339)
