Basically what I asked above, I’m trying to find an up to date esk. list of plugins that are supported on 1.13. I can’t find any such list here on spongeforge, though I would have assumed there’d be a list like area for plugins by versions of minecraft.
Sponge itself isn’t updated to 1.13. Forge itself isn’t updated to 1.13. There will be more information about the upgrade to 1.13 soon in the announcements area of the forums.
