Thanks to Misty who let me have her patched file, I was able to check if a file need an update.
Here are the mods that needed to be updated for 1.66:
Mods that do not need an update:
Less roaming around town
No/Less autonomous 'Sniff out collectable'
Weatherstone Map Tag mod
Because a lot of people (including me duh) are still using patch 1.63 I will keep making my mods for this patch, but I will also keep checking if they need updating for 1.66
