Do methods created in one version work in another?

Hi Guys !!

I have this question...

Do methods created in one version work in another?
I downgraded from version 4.17 to 3.95 and kept the Methods folder, which I then moved to the installation folder.
Some methods work and open correctly, but others don't. Why is this happening?


Thanks !

Version 4 stores methods in a different format. AND it has different features and arguably fewer bugs.

So, it's surprising that *any* methods saved under version 4 work with version 3. I wonder if really they were old V3 methods still? (Not overwritten by V4).
