Record.get_info did not change in Isabelle2016. What do you mean precisely?

The old datatype package has been superseded by BNF datatypes about 2
years ago. The BNF guys can say how to access the datatype info,
although that has changed significantly.

I somehow suspect that you are trying to move from a very old Isabelle
version to Isabelle2016, but this is a bad idea. You should always
follow each Isabelle release step by step.

I don't understand that paragraph. How is this related?

How is this related at all?
