Hello
Can you update this mod to 1.12?

Current sources are fully compatible with new versions except for a few strings.
https://github.com/Ghostlyr/TitleChanger/blob/master/releases/titlechanger-1.1.2.jar

I will work on updating this mod when I get some free time.

It shouldn't be too difficult to finish the update, I can't imagine it taking more than a few days.
