  • Agent API now supports providing a callback to determine what error group an exception should be grouped under. See our SetErrorGroupCallback API documentation for more details. #1434
  • Adds the Supportability/Logging/Forwarding/Dropped metric to track the number of log messages that were dropped due to capacity constraints. #1470


  • Reduce redundant collector request data payload logging in the agent log at DEBUG level. #1449
  • Fixes #1459, a regression in NLog local decoration when logging messages with object parameters. #1480


  • Renamed NewRelic.Providers.Wrapper.Asp35 to NewRelic.Providers.Wrapper.AspNet since this wrapper instruments multiple versions of ASP.NET. Updated installers to remove old Asp35 artifacts. #1448
