Just found this: https://github.com/MinecraftForge/MinecraftForge/pull/6467
So it looks when it gets merged, it will work automagically with the new Config API.
I added a notice about that in my mod.
Hi all,
I was trying to make a configuration GUI using the Config annotations (described here https://mcforge.readthedocs.io/en/latest/config/annotations/#config-use ) but they're not available in 1.15.2. I checked github for historical versions and the Config package disappeared in 1.13.x version.
Is there any reason for that?
Thanks
