• [$] Python's experimental JIT to be removed

    From LWN.net@86:200/23 to All on Tue Oct 27 06:40:09 2026

    Python's experimental
    just-in-time (JIT) compiler, which was added to CPython in 2024 for the 3.13˙release,
    is on its way out. In June, the Python steering council announced
    that it was pausing work on the JIT in CPython's main branch until there was an accepted Python Enhancement
    Proposal (PEP) that addressed concerns about maintenance, compatibility, and set clear success metrics as well as a timeline for completion. After creating PEP˙836 ("JIT Go Brrr: The
    Path to a Supported JIT Compiler for CPython")
    to try to meet the council's request, and after months of discussion, the
    JIT maintainers have withdrawn the PEP. For now, it appears that development on the once-promising project has come to an end.
