Sage SDK and Sage 50 Accounts

I have a question about the Sage Developers Programme that i'm hoping someone from Sage can answer.

It mentions on the overview of the Sage Developers Programme that when you join, you get access to the Sage Data Objects dll's. However, looking in Visual studio, I can already reference Sage Data Objects 24.0. - And I have tested this by enabling 3rd party integration in Sage and quickly copied their example of Creating a Sales Record.

So my question is... Is there some other dll's that you get when you join the programme? Or is it just the case that when you join the programme, you get access to the documentation for the Sage Data Objects library and help from the developers support team?

If the latter, then surely I would be able to just join the developers programme for a month, which would give me access to the documentation, which I could then download and keep indefinitely? The only reason to keep subscribed is if you needed help from the Sage Developers?

 

Thanks
