Is there’s a way to run a report in Pega to find out new data types that were created as well as a report on new data fields added to data types?

I knew the data types are essentially added to Application Stack and each data type is mapped to a table via class mapping, but I'm trying tofind a consolidated list of all data types exist in the Environment. 

Finally, are there are OOTB Audit avaiable where I can see the list of changes to the rule/fields or changes to the data in the data type.
