All changes to the magic number in Lib/importlib/_bootstrap_external.py are attributed with 3.7a0. But they were made at different stages. There is also inconsistency in specifying Python version for older changes. Some authors specify the first Python version after bumping the magic number (i.e. the version that was released with this magic number). Others specify the Python version after which the bumping was made. I think the former is correct. The proposed PR fixes Python versions and adds issue numbers if known. I have tracked only changes in Python 3.x.

Maybe we should simply delete this comment? I'm not sure how useful it is.

I think it is useful to have such table somewhere. It give the impression about the history of bytecode and pyc format. There are third-party projects that try to support Python bytecode of different versions, they need such table. There is a simplified version of this table in PC/launcher.c, it is needed for suggesting the Python version by the magic number. And this table is just interesting for Python developers, especially if they made the change in the bytecode.
