Notes should be taken with a grain of salt as it's just notes I took during the livestream and since I'm no contributor to forge I cannot attest to the accuracy of facts.

1.13 General

• cpw is rewriting the mod loader and it's going to be merged into 1.13 forge
• 1.13 forge will have java 9 support. (May happen sooner rather than later)
• The mod loader carries a lot of technical debt, which is the reason the load speed is a bit slow, they're working towards improving the performance of the loader.
• Java 10 & 11 support depends on Mojang using it. Go yell at them for support.
• Forge will receive a full audit for 1.13, going over all of the classes for redundancies. Stable 1.13 Forge might take months.
• New coremod system for 1.13, coremods are necessary for forge, but people tend to overuse them right now.
• JavaScript system to modify base classes.

1.13 and 1.14 are lumped together in this doc, you're on your own if you just want to go to 1.13 and not 1.14, for some reason.

Things in Advance

• ResourceLocation now throw on non-snake-case names instead of silently lowercasing for you, so you probably should go and change all those string constants now. More precisely, domains must only contain alphanumeric lowercase, underscore (_), dash (-), or dot (.). Paths have the same restrictions, but can also contain forward slashes (/).
