It seems that the compiled help CHM file is not distributed with Python on Windows since 3.11, but the content is now distributed as standalone html files.
But I couldn’t find any formal note about that, and it’s not listed on What’s New for 3.11.
So I can be clear I’m not missing something, is there a change request where this was altered?
(I’m not suggesting that we should keep CHM files. It appears that Microsoft are deprecating it: https://learn.microsoft.com/en-us/dynamicsax-2012/appuser-itpro/deprecated-chm-help-files)
I don’t think a formal note was made, but I found this: Include HTML docs with Windows installer instead of CHM · Issue #91242 · python/cpython · GitHub.
Oh well found! That’s helpful to me. Thanks!
