Running Latest Dynamo Version in Dynamo Studio 2016?

Is it possible to run Dynamo version 1.2.1 in Dynamo Studio 2016? I installed Dynamo Studio 2016, then ran the latest version 1.2.1 installer but About said it was 1.1.0.

Is there somthing inherently better in Dynamo Studio 2017 than Dynamo Studio 2016, or is it the ability to run the latest Dynamo version?
