Python 3.13 is a "bridge release"—laying the groundwork for the no-GIL future and JIT-enabled 3.14. Upgrade today for the REPL, but watch the space for the real speed gains coming next year.

Some key features of Python 3.12 include:

Exception tracebacks and prompts are now color-highlighted by default , making it significantly easier to parse errors at a glance.

Note: This is an early preview. Do not expect miraculous speedups for small scripts or I/O-bound tasks yet.
