Maintenance releases during this time included critical security patches (such as libexpat upgrades) and hundreds of bug fixes to ensure the 3.13 series remained a reliable choice for production environments. Python 3.13 Release Timeline Summary PEP 719 – Python 3.13 Release Schedule
If you are currently running Python 3.13.0, upgrading to 3.13.1 is highly recommended. It resolves several medium-priority issues that could affect production code, particularly in edge cases involving asynchronous programming and the new REPL history persistence. @dataclass(immutability=True) class Point: x: int y: int To
Based on PyPy, the new REPL introduced multi-line editing, colorized tracebacks, and a more intuitive help system.
