In Hubspot custom code you can select between Hubspot client v3,v8,v10. I really wonder where I can find the documentation to explain the difference between the custom clients
In this documentation Workflows | Custom Code Actions | HubSpot there is also only a reference to v3.
I also wonder what the EOL of the different versions is.
Hey @mdierckx! Thanks for your post 
The differences between the v3, v8, and v10 custom clients can often relate to performance improvements, new features, and updates in the HubSpot API. I do see a reference to v8 in the article you linked here, but I want to see if any of our subject matter experts have any other resources for the finite differences between these versions!
@GRajput , @SteveHTM, @Humashankar -- are y’all able to provide some clarification on the differences between these versions of the APIs?
Best,
Kennedy
