About this Mod

About

A quick, dirty and otherwise unfinished NeoForge 1.21.1 mod that backports player-visible content from later Minecraft
versions (blocks, items, mobs, worldgen, biome / sound / look variants).
Vanilla namespaces (minecraft:) are preserved wherever the
upstream content does in the hopes when updating items and blocks shouldn't disappear.

I originally created this mod for a friend's server because nearly every backport mod was either bad, or used MCreator.
This most is pure distilled Mojang code, mixed and adapted to 1.21.1 whenever possible.

I'm deciding to publish this mod now before it rots forever in my HDD.
Won't be publishing it as open source because its code lives in an odd state of being heavily derived from Minecraft's code,
but Modified enough where it is its own thing.

If there's any other feature that should be backported shoot me a message whichever place you find that can be used
to direct a message to me.
