Feedback Welcome

latest release shaved ~13MB off of minimal and full install :smile:! what was removed or further compressed?

Which platform?

If one of the distributions that’s cross compiled, like Windows or Mac for Apple Silicon, then some of the difference may be removing a “compile-xpatch” file (that was never intended to be included).

on windows

Yes, that’s the biggest difference between CS and BC.
