New features and improvements:
Java instrumentation by XML new properties:
- traceLambda - to trace lambdas inside a method
- traceByReturnType - to trace all methods in a class that return a given type
These are compatible with Java and Scala. For more information, see Java instrumentation by XML.
Scala APIs
New artifacts allow Scala code to be instrumented using a fluent Scala API instead of the Java annotations. There are specific artifacts for versions 2.10, 2.11, 2.12, 2.13 of Scala. Scala 3.0 users can use the 2.13 artifact.
For more information, see Scala instrumentation.
