The second beta is now available for testing of the upcoming Python 3.13 release that is bringing an experimental JIT, a new interactive interpreter, and other big features for this annual Python feature release.

Python 3.13 has been baking a new and interactive interpreter based on PyPy, an experimental just-in-time (JIT) compiler that is working towards big performance improvements, an experimental free-threaded build mode that disables the Global Interpreter Lock (GIL), the cyclic garbage collector is now more incremental, new typing features, and other significant features and other changes.
