Python's steering council paused JIT compiler development on the main branch in June 2024, requiring a standards-track PEP for continued work. The experimental JIT was added to Python 3.13 in 2024, but proceeded without formal community consensus via a standards-track proposal. PEP 836 is now under discussion to establish the JIT as an officially supported CPython feature.
CPython is experiencing a significant surge in security reports, with CVEs, GitHub Security Advisories, and email submissions all increasing substantially since 2024. The Python Security Response Team, guided by Security Developer-in-Residence Seth Larson, manages this influx through improved reporting processes and formalized team responsibilities outlined in PEP 811.
