I also added the @Fidget-Spinner, because I remember his early design involvation while he worked at Quansight.

I think the main thing I did that is coming in 3.14 is the stackrefs. But we needed that for the intepreter anyways so it probably counts? Either way I can be left out if the others feel inclined to.

Anyway, feel free to propose change as same as what we did for 3.13. |

| Free-threaded mode (:pep:`703`), initially added in 3.13, has been significantly improved. The implementation described in PEP 703 was finished, including C API changes, and temporary workarounds in the interpreter were replaced with more permanent solutions. The specializing adaptive interpreter (:pep:`659`) is now enabled in free-threaded mode, which along with many other optimizations greatly improves its performance. The performance penalty on single-threaded code in free-threaded mode is now roughly 5-10%, depending on platform and C compiler used. | ||
