Python 3.13.1 Release Notes 2025 [upd] ●
The diagnostic capabilities introduced in 3.13 are refined in 3.13.1. Tracebacks are more accurate, and the interpreter is better at identifying the exact cause of an error (e.g., incorrect keyword arguments are now explicitly suggested).
The defining characteristic of the 3.13 branch is the introduction of several "experimental" builds that pave the way for massive performance scaling in the coming years.
The Python 3.13 series represents a transformative moment for the language, shifting focus from purely incremental updates to foundational architectural changes. Python 3.13.1, the first major maintenance release, continues this momentum into 2025 by refining the experimental features that define this generation: a free-threaded mode and a Just-In-Time (JIT) compiler. python 3.13.1 release notes 2025
The 3.13.1 maintenance release contains roughly 400 bug fixes, documentation updates, and build-script improvements. Below are the highlights of the specific fixes in this version.

Python 3.13.1 is a significant update that includes a range of improvements and enhancements. Users are encouraged to upgrade to this version to take advantage of the new features, performance optimizations, and bug fixes. The Python development team is committed to delivering high-quality releases, and this update reflects that commitment.
Python 3.13.1 is a robust, secure, and stable release. It solidifies the ambitious changes introduced in 3.13.0. While the experimental JIT and free-threading features continue to be opt-in work-in-progress features, the core interpreter is now faster, more user-friendly, and more reliable than ever before.
Perhaps the most anticipated change in Python's history, introduces an experimental build that allows Python to run without the Global Interpreter Lock.
