Improvements
- Distributed tracing: With distributed tracing spans and/or Infinite Tracing, the Java agent will now incorporate additional information from the transaction event on to the root span event of the transaction. 
- New TracedMethod.addCustomAttribute(...) APIs have been added for adding attributes directly to spans. - Note: Any attribute include or exclude settings specific to transaction events should be applied to your span attributes configuration or your global attributes configuration. 
- The Java agent now uses AWS's IMDS v2 to gather instance information. 
Fixes
- Jetty JMX metrics would not report when running embedded in Spring Boot.
- Local configuration settings could revert to the default following an agent reconnect.
