Thanks. I get it.
But I still have 2 question.
First, Is the change permanent? When the Minecraft 1.17 comes, I think lots of modders need adapt it. And then I have got to do as well.
Second, Will the old mappings be still supported in the future? If not, for the portability, I need learn new mappings instantly.
Well, by the way,there're two difficulties for me -- where can I learn the new mappings because the website doesn't provide; new-version forge provides a lot of hardcore premeters such as p_11111_11(is it a point?).
Edited:
Thank you. I've searched for Minecraft Forge Mappings on Google and now I know what it's and how to work.
