I’m trying to upgrade our massive production codebase to v12, so please expect several new topics 
I just got this in the compiler terminal output:
The field ‘js-post-build’ found in the package config of ‘pace’ is not supported by ReScript 12’s new build system.
Yet, the docs still have it.
I really hope it’s not gone away because if it has, we will be stuck on v11 probably for ever
