Autumn Forest (Oak/birch with autumn colored leaves or a maple tree

Note: This is not an original idea, just updated with elaboration based on the current version and state of Minecraft. Also making sure this idea doesn't get buried because it's a good one!

The Autumn Forest could be a variant of the normal forest or be an entirely new forest. If it were a variant of the normal forest, it could come with a variant of oak - autumn oak and a variant of birch - autumn birch. Both of these trees would use the same logs and same leaf texture - the only difference is leaf color. Perhaps autumn oak trees would have orange and or red leaves and autumn birch trees would have yellow and or orange leaves. Another way to do the autumn forest is perhaps introduce a new tree - the maple tree. The tree would have a new shape, wood, and leaves.

For other characteristics of the forest, the atmosphere should be foggy - similar to the pale garden. The ground would be covered in leaf litter and perhaps a new type of leaf litter too - which has red, orange, and yellow leaves. The biome should also have occasional groups of mushrooms and also pumpkins. Also, the bush would be replaced with the dead bush, and the grass wouldn't be as lush green as a normal forest.
