We have some new pages for deprecations, see:

• https://github.com/python/cpython/tree/main/Doc/deprecations

These RSTs are .. include::d on https://docs.python.org/3.14/deprecations/index.html and in the What's New pages such as https://docs.python.org/3.14/whatsnew/3.14.html#pending-removal-in-python-3-15 and https://docs.python.org/3.14/whatsnew/3.13.html#pending-removal-in-python-3-15 (and so on) to avoid duplication.

Please could you list these deprecations in one of those files? I guess we're not setting a version in which to remove? In which case, "Pending Removal in Future Versions":

• https://github.com/python/cpython/blob/main/Doc/deprecations/pending-removal-in-future.rst

[AA-Turner]

I do wonder if we should be more explicit in documentation, or improve the warning some other way? This is a very long-standing deprecation warning, so clearly users are not seeing it.

A crude search (using [^es] to exclude warnings.warn and console.warn) gives ~180k files with .warn( and 1M+ files with .warning(.

There's a lot of false positives in there.

That's something like 0.6% of projects.

A few of these are also changelogs ("replace logging.warn with warnings.warn"), there's also the pylint and Ruff linters in there.
