I have updated Wurst, WI Zoom and Mo Glass to support Minecraft 1.20.4-rc1.
In case you missed it, Minecraft 1.20.3 was just released yesterday, but it contained a critical bug causing decorated pots to sometimes delete items placed inside it. That's why Mojang is now rushing out 1.20.4 as a hotfix release.
Release candidate builds have historically been fully compatible with the final release. So if you're eager to start hacking in Minecraft 1.20.4 as soon as it comes out, you might want to download this build in preparation.
