Python 3.11

Python 3.11 was released in October 2022, will receive bug fixes until May 2024, and will receive security patches until October 2027.

Faster runtime

The new 3.11 is 22% faster than 3.10 when measured with the Python performance benchmark suite. The result depends a lot on your application and will usually range between 10% and 60%. A series of optimization into how code is parsed and run together with startup improvements have made this possible, as part of a project branded as Faster CPython that is focusing on making an interpreter faster.

Enhanced errors in tracebacks

Building on the success achieved with the improvement of error messages in Python 3.10, 3.11 has done substantial work to facilitate the debugging of errors in traceback through PEP 659. The interpreter will now point to the exact expression that caused the exception, allowing a developer to quickly figure out the root issue without using a debugger.
