• The JIT compiler has been significantly upgraded and is now used for the [official Windows 64-bit binaries](link to a ref in the build section)

The JIT is already included in 3.14 and off per default (--experimental-jit-off) and the same setting is used for 3.15.
So I am unsure about adding the link, especially using now as this might suggest that it was not the case earlier?

Sorry, I mixed up two unrelated things there! Let's try again:

Shall we add a new entry in the release highlights about using the tail-calling interpreter for Windows 64-bit binaries?

https://docs.python.org/3.15/whatsnew/3.15.html#summary-release-highlights

I think an entry would fit nicely there 👍

Windows 64-bit binaries now use the tail-calling interpreter

Yeah! That's cool, good job!

Thanks!
