1.42.0

Known Issues

This release contains a critical bug that may cause intermittent crashes when using profiler.

To avoid this bug you can either upgrade to v1.42.1, revert to v1.41.2, or:

• To greatly reduce the chance of crash, disable native stack collection via -Ddd.profilng.ddprof.cstack=no
• To completely eliminate the chance of crash, turn off Datadog Java profiler via -Ddd.profiling.ddprof.enabled=false and use only JFR, when available
