I was curious why my VS installer still shows only 3.9 (Out of support), and following the threads via profiling I end here. Presumably more work to do before full support for 3.12, but since then there's 3.13 on the horizon, with advanced notice of what's changed in the beta here: https://docs.python.org/3.13/whatsnew/3.13.html

Hi @tyeth, thanks for your suggestions! You're right, debugging and profiling will require a significant amount of work to support. Please check out this link for the related profiling task: https://github.com/microsoft/PTVS/issues/7904

Bruh why not just release support without profiling so they can at least not get a message about using 3.12 or even 3.13 or even 3.14.0a0 (cpython main).

At least for the Preview version of PTVS for VS Preview 17.11.
