This release, 3.13.0rc1, allows only reviewed code changes considered clear bug fixes before the final release. ABI changes are halted, aiming for minimal code modifications in the 3.13 series.
Encouragement is given to third-party Python project maintainers to ensure compatibility with Python 3.13, urging the publication of 3.13 wheels on PyPI. Binary wheels from 3.13.0rc1 will be compatible with future 3.13 versions.
New features in Python 3.13 include an enhanced interactive interpreter based on PyPy's, an experimental free-threaded build mode to maximize concurrent threads, and a preliminary JIT for better performance.
Core developers are reminded to focus on documentation, ensuring all changes are properly documented, included in 'What's New,' and flagging any undocumented changes.
