A large number of .. versionadded, and .. versionchanged directive are from long-unmaintained version of Python, from a rough search through the codebase/docs (excluding whatsnew), of everything 3.5 and before:

   4 .. versionchanged:: 3.0
  33 .. versionchanged:: 3.1
  55 .. versionadded:: 3.1
 143 .. versionchanged:: 3.2
 152 .. versionadded:: 3.5
 159 .. versionchanged:: 3.4
 182 .. versionadded:: 3.4
 192 .. versionchanged:: 3.5
 209 .. versionchanged:: 3.3
 219 .. versionadded:: 3.2
 295 .. versionadded:: 3.3

I think that at some point it might be useful to remove those, and write the documentation as if what was changed/added has always be present.

Is there any policy as to when those can/should be removed/rephrased ?
