Minecraft: 1.11

Great... I apparently tested everything with 2188 (edit: which I'm pretty dang confident was the "recommended" build when I looked), and then what does 2189 (the currently recommended build) go and change?

Enable Enforcement of modid formatting. Must be lowercase and <= 64 characters

MinecraftForge/MinecraftForge@7fe8c48

Apparently even "Recommended" builds aren't safe from intentional breaking changes.
