Overworld Update

An overworld update would be amazing, not caves bc we have plenty of those by now but the biomes. The last memorable, good Minecraft update I can even remember is the Nether update and it was amazing. Something similar for the overworld would be fantastic. Not necessarily new biomes but rework some of them, and add more unique structures, new rare and common ones would really bring back a large survival playerbase. Also making bigger villages would be cool.
