Desderpool posted this about the Python upgrade
Many have started reading about EA's upcoming Python upgrade. Just like EA said, this will break all script mods. That definitely includes MCCC. When it happens, all I can do is get everything recompiled in 3.7.0.
I'm not sure what kind of language differences there are between the current version and 3.7.0, so I don't know if anything else really major will happen. I know that the "decompiler" script-modders use each time EA does a release to get the latest version of Sims 4 script-code to mod will no longer work in 3.7.0 and that could cause problems if someone doesn't come-up with an alternative (like EA actually providing the script each time...)
Just a heads-up. This is coming. Not much we can do about it but deal with it when it gets here.
Thanks! :)
