Python 3.15.0 candidate 2 has been released as the final RC before the October launch, with only clear bug fixes permitted from this point onward. Release manager Hugo van Kemenade encourages third-party maintainers to test against the RC and publish wheels on PyPI early to ensure readiness.
Background
Python 3.15 follows the typical six-month release cycle, with the final version planned for October 2026. The RC phase is a critical window for third-party library maintainers to catch compatibility issues before the stable release ships.
