Relevant highlights (some C\u0026P verbatim) from the release announcement:\r\n\r\n- Pre-C89 compilers are no longer supported. This should not be a problem for us, as [we're using C11](https://peps.python.org/pep-0007/#c-dialect).\r\n- `AC_USE_SYSTEM_EXTENSIONS` now enables C23 Annex F extensions\r\n  by defining `__STDC_WANT_IEC_60559_EXT__` (is this a problem?)\r\n- ~~Autoconf now quotes ```'like this'``` instead of ``` `like this'```; perhaps we should clean up our quoting in a separate first, so the 2.72 change is easier to review.~~ \u003c= not worth the churn\r\n- Improved compatibility with a wide variety of systems and tools\r\n  including CheriBSD, Darwin (macOS), GNU Guix, OS/2, z/OS, Bash 5.2,\r\n  the BusyBox shell and utilities, Clang/LLVM version 16, the upcoming\r\n  GCC version 14, etc.\r\n\r\nThe other version requirements (Perl, M4, etc.) should not affect us.\r\n\r\nPreliminary actions:\r\n- [x] #116016\r\n- [x] #115792\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-128411\n* gh-128502\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/erlend-aasland","@type":"Person","name":"erlend-aasland"},"datePublished":"2024-02-21T12:18:59.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":20},"url":"https://github.com/115765/cpython/issues/115765"}
