While there is a lot of speculation around this update, fans are quite certain that it will be quite special and loaded with a lot of exciting content. One has come across reports offering a glimpse of all that this update will offer.
When you see the confirmed list of content for the 1.21 update, you realize that a new biome will not be added to it. Since most updates in the game have brought in a new biome, this particular update not bringing one would seem strange to most players.
Those who are feeling about the exclusion of a biome could seek solace in the fact that there is still a good chance of the update introducing a new biome.
The Nether update was the first Minecraft update to have featured a new biome. Since then, most major updates have marked the arrival of a new biome into the game. Through update 1.20, one was introduced to a pink cherry grove biome. Mangrove swamps were brought into the game via update 1.19.
