It’s not in version 1.3, but for all other versions, you can look at the changelog (Annex B) in the PDF for differences from one version to another.

For examples, what’s the difference between version 1.2 and 1.3? I created a 1.2 implementation about 10 years ago, and I’d like to know specifically what I need to add to make it 1.3 compliant. I looked at the 1.3 MPI document but it does not appear to have a section that shows the differences from the 1.2 version. Also, If I intend to update the implementation to 3.1, what is the best way to know the differences between 3.1 and 1.3?
