New biomes:
- Mesa, which is made entirely of clay. Also has red sand.
- Mega taiga: 2x2 birch trees with podzol, which acts vaguely like mycelium.
- Ice plains spikes: ice plains with packed ice stalagmites.
- Savannah: flat like plains but also has acacia trees.
- Roofed forest: almost completely topped with leaves, trees and giant mushrooms are up close to each other. Has mostly dark oak wood.
- Birch forest
- Sunflower plains: like plains, but can have sunflowers.
- Forest flower: a forest with the new flower types.
- Deep ocean: really deep ocean.
- Extreme hills+: like extreme hills, with birch trees.
- Snowless taigas.
- M-variants are much more mountainous.
- Hills-variants are hilly.
- Plateau-variants are hilly but with flat tops.
Oceans are smaller (thank God!)
New blocks and items:
- Acacia and dark oak wood added. Slight texture change to all.
- Lots of new flowers! Still got dandelions. Red poppies replace roses. Added blue orchids, allium, azure bluet, tulips which have many colors, oxeye daisy, double-height sunflowers, double-height lilacs, double-height rose bushes, double-height peony. They are mainly used for dyes.
- Stained glass and pane counterparts. This is particularly awesome.
- Packed ice: lacks most features of regular ice, but you can still slide on them.
- Red sand: acts like regular sand, but you can't make sandstone from it.
- Portals can be much bigger.
- In addition to regular fish there is now salmon, which always gives a tuxedo cat, clownfish which always gives a siamese cat and is a poor food source, and pufferfish which is used in a potion of water breathing, gives you a ginger cat, and will make you sick as heck.
- Fishing has been changed a bit so now you get junk and treasure sometimes.
There are other changes no doubt but I'm not terribly interested in them.
