  • We have greatly optimized the profiler's tracing/instrumentation mode. Profiled applications now run 5 to 10 times faster.
  • Profiler result files are now locked when opened so that they can no longer be accidentally deleted, which caused the user interface to crash in the past.
  • Profiled applications no longer crash if the type information of a raised exception cannot be retrieved.
