I've got a full FAQ on this that I'll be posting tomorrow morning, but the short version is this:
- All script mods will break because of the Python update. Script mods include a .ts4script file. If it has a .ts4script file, pull it out and wait for an update.
- The usual breakage of other mods and CC will happen as a result of things other than the Python update. As is typically with EPs, that's mostly going to be mods, not CC, but sometimes whole categories of furniture break.
Someone else can comment on the process of updating script mods, but the short version is they will all need to be recompiled in Python 3.7.0.
