1.56.0

Known Bugs

Note

If you are experiencing issues with NegativeArraySizeException or JVM crashes, please update to the latest version or disable the CodeOrigin feature using the DD_CODE_ORIGIN_FOR_SPANS_ENABLED=false environment variable or the -Ddd.code.origin.for.spans.enabled=false Java properties.

If you are using the liveheap profiler functionality you may experience occasional JVM crashes. In case you see the crashes happening disable the profiling library via DD_PROFILING_DDPROF_ENABLED=false environment variable or the -Ddd.profiling.ddprof.enabled=false. The fix fix is available in release 1.56.3.
