About this project

What does Brecher's Backport add?

Brecher's Backport does just what it says on the tin - backports all of the latest/finalized features in the Vanilla/main branch of Minecraft back to 1.21.1, so you can get the latest mobs, blocks, and features in your modpacks. Aside from a few specific options/toggles, this is a 1:1, true recreation of these vanilla features.

The configs allow you to selectively enable/disable features. I've also included a few additional options to tweak certain generation settings, like how big dappled forests or pale forests can generate as.
