Apart from graphics, attack animation, environmental changes and various effects. Dota2 is no different from Dota 1 per se.

All the changes that you see right now in dota2 are now map updates for dota1 ( yes the crazy 6.80 update which essentially changes a lot of gameplay was a (map) update in dota 1 too )

For example, The orb effect had always been that way. 'Orb effect does not stack' Do you remember that on items in dota1? It used to explicitly say that in the item description in dota1. In dota2 they explain it a bit better.

Sorry, I wasn't clear: I know that orb effects are identical in dota 1. I am saying that many of the quirks of dota 1 have been carried over to dota 2 - Skadi's orb interactions is one example of that.

One difference, for example, is the interaction between naga siren's net and manta style - in dota 1 it dispells the net, but not dota 2. There are subtle differences like that but they are the exception.
