PEP 594 – Removing dead batteries from Python's standard library
Hmm, should perhaps this be worthy of a major version number bump? Yes, it's not as large or as breaking of a change as the 2.7->3.0 transition, but by removing modules from the standard library, backwards compatibility is being broken. Now, perhaps most people don't use those features anymore, but for those people who do use and rely on these modules, a major version number change would be a welcome signal that their code will no longer work with the new version.But, after the initial pain of the 2.7->3.0 transition, I doubt we'll ever see another major version number jump, even if a logical use of version numbers would merit it.
