I'm waiting on #4698 to merge. That will upgrade the nether pathfinder version to 1.6.

Changed shadow to new URL because of GradleUp/shadow#908.

@leijurv Instead of working on 1.19.4 forever, I feel like Baritone should be developed on the latest Minecraft version. I know that matching the current 2b2t version might be a reason to keep it at 1.19.4, but people can just use ViaFabricPlus and also 2b2t updated to 1.21.4 anyway.

[Murat65536]

Also Dependabot or something would be good

[leijurv]

My position is that baritone should just follow the version of 2b2t. So yes we could update the development version accordingly

wtf why is copilot here
