• Fixes to IIS event handling.
• You can now customize collection settings using the collect dialog and then copy the command line to the clipboard using the “Copy Command Line” button.
• Fixes to rundown to avoid collecting ClrStack/Walk events unintentionally.
• Expose PerHeapHistory data for the pinned object heap in .NET 5+ in the GC Stats raw XML.
• Read the maximum number of ETW sessions from the registry instead of assuming a hardcoded value of 64.
• Performance improvements to RCW handling in GC heap snapshots.
• OOM recovery improvements to GC heap snapshots.
• Expose the ability for sessions to set the EVENT_TRACE_NO_PER_PROCESSOR_BUFFERING flag.
• Miscellaneous documentation improvements.

• Disable collection of TPL events by default due to their verbosity. This is configurable via /TPLEvents.
• TraceParserGen fixes.
• Fix when parsing fixed-length arrays in TraceLogging events.

  • Removal of Silverlight support for heap dumps.
  • Removal of HeapDump /dumpSerializedException option for .NET Native heap dumps.
• Add handling for copying and consuming time ranges with cultures that use spaces as their number grouping delimiter.
• Fix broken storage and lookup of RelatedActivityID in the ETLX file format.

• Add support for advanced memory investigations of the JIT.
• Include TraceEvent.props in the buildTransitive directory of the TraceEvent NuGet package.
• Symbol / source file improvements.
• Remove dotnet.myget.org from the default symbol path, since it has been decommissioned.

Roll-up through 11/8/2020.

• Fix PDB discovery for .diagsession files.
• Enable consumption of merged ETL files when they don’t match TraceEvent’s naming scheme.
• Parser and GCStats support for the pinned object heap.
• Numerous spelling fixes.

Roll-up through 09/21/2020.

• Support for capturing traces of Windows Process-Isolation containers from the host rather than from inside the containers:
  • Adds /EnableEventsInContainers flag to enable user-mode provides inside containers to send their events to host sessions.
  • Adds /EnableSourceContainerTracking flag to tell ETW to tag each user-mode events that originates from a container with the container ID.
  • Exposes TraceEvent.ContainerID for user-mode events that have a container ID (enabled with /EnableSourceContainerTracking).
  • Enables on-host symbol resolution of containerized DLLs by reaching into the container as long as it is still live, and extracting the PDB information.
  • Adds /ImageIDsOnly flag to the merge command to enable merging on the host and inside one-or more containers to enable symbol resolution off-box.
    • Merge once without this flag on the host, and then merge with this flag inside of each container.
• Package vcruntime140_1.dll with amd64 native dependencies to fix loading of amd64 msdia140.dll
• Fix a possible memory leak in GLAD APIs.

Roll-up through 09/14/2020.

Most visible changes:

• Fix TraceEvent NuGet package to include msvcp140.dll and vcruntime140.dll.

Roll-up through 9/4/2020.

Most visible changes:

• Package msvcp140.dll and vcruntime140.dll alongside msdia140.dll, since the new version of msdia140.dll is dependent on them, and not collection machines.
• Updated KernelTraceControl.dll to the a newer version to work around reported merge failures.
• Fixes for Linux trace parsing failures.
