I just noticed that new Dynamo update is available. Here is a screenshot of my current Dynamo version (2.0.2.0): ![dynamo](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/0/8/08e116deeecc9f6fe36822c380ea6ae852100dd4.png) If I update, will it somehow affect the previous .dyn files? Or was this an issue only with the switch from Dynamo 1.x to 2.x? Thank you for the reply. ---

As with Eric, I have seen some issues associated to .dyf files. Technically the dyns are ok, but if the wheels fall off the car doesn’t run so well. ---

Thank you, both @erfajo and @jacob.small I never created any .dyf files, and seems like the upper linked topic is related with updates from Dynamo 1.x to 2.x? Or did I misunderstand that? ---

It’s 2.0.x to 2.0.z updates as well. It’s specific to people who make the custom nodes which increase the efficiency and effectiveness of Dynamo, so while it may not impact you from a ‘we don’t make our own custom nodes’ it would impact you if you use Orchid and a few other key packages. ---

Thank you again @jacob.small, @erfajo. These .dyf files can contain both design script and python custom nodes? ---

I’m not sure I understand your question, but .dyf file can contain anything a .dyn file can… ---

I see. So it is essentially a .dyn file saved in a single node, so to say? ---

That’s one way to think of it, yes. Review the primer as there are good examples there. ---
