This mod removes the biome clustering by temperature in 1.7 and instead distributes biomes randomly, as they were in 1.6.4 and earlier, so you can have hot and cold biomes next to each other (biome size and terrain generation is otherwise default). In addition, a new world type is added (Random Biomes, using ID 15), so you can still play default/large biomes/amplified worlds in the modded game without worrying about messing them up.
