Purpose
Overhauled Overworld reimagines the vanilla overworld biomes, using custom sky, water, grass and vegetation colors, along with extensive custom features, to create a more immersive, atmospheric, cohesive and picturesque world. This is all done entirely without modding, and also with a focus on compatibility with other worldgen packs and mods, such as Tectonic and Reterraforged.
What to expect
Overhauled Overworld adds many sub-variants to biomes, as well as unique and rare transition regions where various biomes meet. Trees of all shapes and sizes fill the world. Stony cliffs and scree escarpments are common in the highlands. Ore blobs (diorite, andesite and granite) no longer pollute the clean grey of stone cliffs. Instead, these ores are found in abundance in their own allocated places. Diorite is readily available in the Flower Forest, granite in the Sunflower Plains and Birch Forest, and andesite in the Meadow and Cherry Grove. Lava lakes and springs are no longer to be found in the surface of overworld biomes, except for the volcanic Stony Peaks and Windswept Hills biomes.
History
William Wythers' Overhauled Overworld was originally released on Planet Minecraft on October 9th, 2020. It gradually rose to the top of the list as the most popular worldgen datapack. It maintained that position for a while, before being outclassed by the creations of a certain silent celestial object. While it no longer holds the top spot on that list, it currently remains in third position. From its inception, Overhauled Overworld was designed with the intention of creating a beautiful, immersive and more realistic experience without making use of modding. The pack was later repacked in mod format by Cristelknight, which has been very useful to the majority of players who prefer mods over datapacks. However the pack remains at heart a datapack.

All Versions
+ Add Version(This is the first release version. A couple of biomes have yet to be fully updated, and there may be small bugs or other issues that will need fixing.)
Note: due to the position of the new Dappled Forest biome, in WWOO this biome is overhauled as a temperate Asian landscape, only home to the giant panda. For the autumnal poplar forests, visit the Windswept Forest biome.
Updated Mushroom Fields to be pleasant biome of giant mushroom forests, grassy fields and sandy beaches.
(For those who prefer the dark alien fungal biome used previously, that variant will be made available as a separate add-on, as many do not care for it. Alternatively keep using 2.5.1)
Huge rewrite of many features for 1.21.5-1.21.6, including entirely reworked system for sub-biomes and border biomes, reworked ocean biomes, new vegetation types, and countless other changes.
