Problem: Sphinx EPUB builder used it until Sphinx 6.2.\r\n\r\nSphinx 6.2 got fixed: it no longer uses this deprecated module:\r\n\r\n* https://github.com/sphinx-doc/sphinx/issues/10440#issuecomment-1556180835\r\n* https://github.com/sphinx-doc/sphinx/commit/a502e7523376e0344c1c9cc8a9d128143cd98b2d\r\n* https://github.com/sphinx-doc/sphinx/releases/tag/v6.2.0\r\n\r\nThis change is [ok for Fedora and RHEL will follow Fedora](https://github.com/python/cpython/pull/104777#issuecomment-1558943517), and it's [ok for OpenSuSE](https://github.com/python/cpython/pull/104777#issuecomment-1559386924).\r\n\r\nIn May 2022, [Debian Stable used Sphinx 3.4 and Ubuntu LTS used Sphinx 3.5](https://github.com/python/cpython/issues/86986#issuecomment-1140493331).\r\n\r\nIn May 2022, Python was modified to require Sphinx 3.2 or newer: see issue #86986.\r\n\r\nSee also details in the [imghdr module removal PR](https://github.com/python/cpython/pull/104777#issuecomment-1558943517).\r\n\r\n---\r\n\r\nAlternatives:\r\n\r\n* Run Sphinx with Python older than 3.13 (ex: Python 3.12) which still had the imghdr module\r\n* Don't remove the imghdr module in Python 3.13\r\n* Provide the imghdr module on PyPI, as it was done with [nntplib (on PyPI)](https://pypi.org/project/nntplib/) -- old Sphinx versions would still be supported in this case\r\n* For Linux distributions: backport the Sphinx 6.2 change to older Sphinx version to support Python 3.13 without imghdr.\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-104819\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/vstinner","@type":"Person","name":"vstinner"},"datePublished":"2023-05-23T20:40:45.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":10},"url":"https://github.com/104818/cpython/issues/104818"}
