Dynamo update, will discontinue previous .dyn files

I just noticed that new Dynamo update is available.
Here is a screenshot of my current Dynamo version (

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.
