As I was playing MC's newest Snapshot I noticed that when I was searching for a new biome. I found that when I did find New ones they were extremely large compared to the other biomes from previous versions. I do not know if this was intentional from the devs, but it was certainly a weird sight.
working as intended. Biome sizes are much larger that they were previously (on defualt).
Although it is working as intended, I agree they are a little large making it harder to find diverse biomes
