Perfect Parity: Spring To Life Edition
by montmaj
Perfect Parity: Spring To Life Edition brings the Spring to Life update into Minecraft 1.21.1 and 1.21.4 as a near 1:1 backport, with cold and warm animal variants, fallen trees and new plants.
What it does
Cold and warm variants of pigs, cows, chickens and sheep spawn according to their biome, and sheep wool follows the biome as well. Wolves gain new sound variants, and the spawn egg visuals are overhauled. Desert and Badlands biomes get new ambient block sounds, and falling leaf particles are added for leaves blocks.
The mod adds vegetation content: fallen tree generation, a Firefly Bush block, Leaf Litter, Wildflowers, Bush, Short Dry Grass, Tall Dry Grass blocks, and a Cactus Flower that can grow from a cactus. Unlike many backport mods that cross major versions, this one targets the minor versions 1.21.1 and 1.21.4, so players on either can keep current mod compatibility.
The mod requires Continuity for emissive Firefly Bush textures and Fabric API. It runs on the client and the server, so both need it. Files are published for Fabric only, for 1.21.1 and 1.21.4, under the MIT License, and the source code is open source.

What the author says
I was sick of Mojang changing and breaking so many mods every update. I wanted to play with my modpack but didn't want to wait for the new features. So this mod asks: "Why not both?" Unlike many backport mods, this does not aim to backport between major versions (e.g., 1.21 → 1.20). Instead, it's a minor version…
