Their docs-only deprecation notice appeared 2.0: https://docs.python.org/release/2.0/api/memoryInterface.html but not 1.6: https://docs.python.org/release/2.0/api/memoryInterface.html Nowadays we call this soft deprecation. Since PEP 445, they are now direct aliases; there are no (additional) binary compatibility concerns over the preferred names.

I think it would be nice to have a table, similar to what I did here.

These had a docs-only deprecation notice since the first version of the docs in this repo. Nowadays we call things “soft deprecated” if there's just a note in the docs. The deprecated directive needs a version, I went with the first one that had the notice (2.0; it's not in 1.6): - https://docs.python.org/release/2.0/api/memoryInterface.html - https://docs.python.org/release/1.6/api/memoryInterface.html Since PEP 445, they are now direct aliases; there are no (additional) binary compatibility concerns over the preferred names. (cherry picked from commit a009e78) Co-authored-by: Petr Viktorin <[email protected]>
