Patrols no longer spawn when the player is close to any village
Added Netherite!
Added Soulsand Valley biome to the Nether
Walls do not have gaps anymore when stacked vertically

Blocks
Many new block types have been added!
Two new wood-like materials - Crimson Stems and Warped Stems
Basalt blocks - you can find them as pillars but they can be placed in any direction
New ground surface blocks: Crimson Nylium and Warped Nylium
New vegetation: Nether Sprouts, Crimson Roots and Warped Roots
Two types of Fungi: Crimson and Warped - try using bone meal to grow them!
Warped Wart blocks
Weeping Vines that grow from the bottom of a block downwards!
A new natural light source: Shroomlights
Added Soul Soil! Whenever fire burns on Soul Soil, it burns with a blue flame!
Soul Soil can be used to craft Soul Torches - and those can be crafted into Soul Lanterns!
Using bone meal on Netherrack can now spread Nylium
Crimson Forest
Crimson Forests can now be found in the Nether!
Crimson nylium carpets the cave floor with all kinds of strange new vegetation
Huge Crimson Fungi make up the "trees" of this forest, with Shroomlights lighting up the forest floor
Weeping Vines grow from the cave ceilings and fungi
Hoglins wander these Forests
Crimson spores swirl through the air
Netherite
A new high level material found in the Nether. Use it to upgrade your diamond gear!
How to make Netherite
Mine Ancient Debris in the lower depths of the Nether. At own risk. No insurance coverage for that.
Refine it into Netherite Scrap in a furnace (although that's kind of slow so you might want a Blast Furnace).
Combine 4 Nether Scrap with 4 Gold Ingots in a crafting table to make a Netherite Ingot.
Netherite effects
Netherite items float in lava. So you don't lose all your gear after that unplanned lava bath.
Netherite items have higher enchantment value than diamond (but not as high as gold).
Netherite tools work faster and last longer than diamond.
Netherite weapons do more damage than diamond.
Netherite armor have higher toughness and durability than diamond.
Netherite armor gives you knockback resistance, so you barely get knocked back at all when hit by arrows and such.
And it looks cool!
Soulsand Valley
Soulsand Valleys can now be found in the Nether!
An open space made mostly of Soul Sand and Soul Soil
Basalt pillars span from floor to ceiling
Fossile remains of unknown creatures from the past litter the valley
Ash falls through the air
A light blue glow envelopes the valley
Beware of Skeletons here
Sounds
Ghasts sounds are now heard at shorter range
Updated block sounds for Bone Blocks, Netherrack, Soul Sand, Netherwart, Nether Bricks and Quartz Ore
Warped Forest
Warped Forests can now be found in the Nether!
Warped nylium carpets the cave floor with all kinds of strange new vegetation
Huge Warped Fungi make up the "trees" of this forest, with Shroomlights lighting up the forest floor
A dark blue fog covers the forest!
Warped spores swirl through the air
The Warped Forests are strange, but also the least hostile place of Nether
World Generation
The old Nether biome is now called Nether Wastes
Made shipwrecks and ocean ruins a bit less common, so you get more excited when you find one!
