@ZiyunShang @AndyDu1985 @mjkkirschner I installed latest Revit Preview Release and sln built with this change. Merging. This should not impact the CI/CD but if it happens, let me know

[ZiyunShang]

Hi @QilongTang , is there a changelist in DynamoCore 2.1.0-beta6967? I found a new folder called IronPython.StdLib.2.7.8 was added. Is this a required component in Dynamo runtime?

[QilongTang]

@ZiyunShang That is a result of update to the newer version of IronPython. @alfarok This is expected new dlls added correct?

[ZiyunShang]

@QilongTang This folder contains a lot of Python files, I wonder if they all need to be added to the installation package? Or just components that are needed at compile time?

[mjkkirschner]

These are the core libraries of python - they need to be distributed with dynamo to support user code that relies on them. python nodes and packages containing python nodes.
