CPython

Python's fifth 3.14 maintenance release, shipped May 10, restores the generational garbage collector from 3.13 after operators saw memory regressions up to 5x; the revert also reaches into Python 3.15.

The Rust for CPython project has achieved cross-platform builds in CI and shifted its target from Python 3.15 to 3.16, setting a July deadline to submit a formal Python Enhancement Proposal that would make Rust a build-time dependency of the reference interpreter.
