According to PEP 387, they can now be removed in Python 3.12.\r\n\r\nI'm not sure that we should actively remove all of these deprecated features, it should be decided on a case by case basis. Backward compatibility is even more complex when it's about security and old security protocols like SSL and old TLS versions.\n\n\u003c!-- gh-pr-number: gh-99023 --\u003e\n* PR: gh-99023\n\u003c!-- /gh-pr-number --\u003e\n","author":{"url":"https://github.com/vstinner","@type":"Person","name":"vstinner"},"datePublished":"2022-06-24T08:14:21.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":8},"url":"https://github.com/94199/cpython/issues/94199"}
