A small complaint and a request from a Grasshopper newb

Hi, I'm new and just learning everything I can about Grasshopper. It's an incredible way to work and really seductive with its intuitive workflow.

But there is one problem for me that's really annoying; 95% of all the available tutorial material seems to be from an earlier build, like .7 or something.

Hexagonal Grid is a lot different with it's inputs and outputs changed a lot, and yeah I know Vector multiplication is now assumed by the ordinary one use serves all multiplication function but still generally  this issue is the only confusing thing in the entire program which is otherwise quite clear. And it's not just these functions...there's quite a few I'm bumping up against and it's really eating into my study time to have to search and search for the substitute which is often the exact same function with a new name. I know there has to be change to have progress but...

I've tried to think my way around this and after a lot of work on various tutorials I've eventually forced things to work but I really wish things hadn't been thrown out with such brutal haste.

Thus I was wondering; is there an earlier build available that would allow me to go back to say, the Grasshopper Generative Modeling For Rhino tutorials?  Link?

Sorry to bother you with this but it would really hasten the learning process..
