It was :ref:`removed in Python 3.13 <whatsnew313-pep594>` after
being deprecated in Python 3.11.  The removal was decided in :pep:`594`.

Possible replacements are third-party libraries from PyPI:
:pypi:`filetype`, :pypi:`puremagic`, or :pypi:`python-magic`.
These are not supported or maintained by the Python core team.

The last version of Python that provided the :mod:`!imghdr` module was
