Python 3.11 Released With Big Performance Improvements, Task Groups For Async I/O
Python 3.11 is quite exciting for its multitude of performance improvements. Python 3.11 is looking much better in the performance department thanks to the Faster CPython Project. In general Python 3.11 can be 10~60% faster than Python 3.10. Pyston and PyPy still hold some advantages in some areas but CPython is at least doing much better than prior releases.
Python 3.11 also adds support for task groups with async I/O, Exception Groups and except*, fine-grained error locations in tracebacks, support for parsing TOML in the standard library, various typing changes, and a variety of other work.
