Improved/More Biomes
by ThirtyFangs
Improved/More Biomes adds new biomes and reworks existing ones through a data pack, with custom skies, ground blocks and tree shapes for each.
What it does
Several biomes get a revised look. Improved Birch Forests gain taller trees, a different ground and red shrubs. Improved Forests bring wider trees, a different ground and fog that appears at times. Improved Savannas receive wider trees, stone patches and baobabs on a changed surface. Improved Taigas, Improved Snowy Taiga and Improved Swamps get custom skies, and the swamps also grow giant mushrooms and new trees. Improved Stony Shore is built from stone and cobblestone ground.
The mod also adds biomes that have no vanilla counterpart, such as enchanted forests and ice caves, plus an Autumn Forests biome with autumn trees. Most biomes carry their own light color, for example a greenish light in flower forests. Custom lighting color support is included for 26.1. The mod is distributed as a data pack, so it is applied from the world's datapacks folder, and it is server required with client optional, meaning the server must run it while players may leave it out. Files target Fabric, Forge, NeoForge and Quilt for 1.21.4 – 26.3, with 13 release versions and snapshot builds published.

How it compares
Autumn Forest is a Fabric, Forge, NeoForge and Quilt option for 1.21.5 – 1.21.8 and is not open source, with the same server-required, client-optional environment. Old Growth Forest covers 1.21.11 – 26.1.2 under the MIT License, but it is not open source either. Snow Under Trees is the only one here that is open source, under the MIT License, and it is server-side only, so clients need nothing.
