Ahh, a freshly baked snapshot! It undoubtedly smells better than the piglins that we just added...

Features in 20w07a

Endermen can now pick up some of the new Nether blocks
Endermen will no longer pick up Netherrack
Gave Hoglins some actual functionality
Added Piglins
Netherite blocks can be used as the base of a beacon and Netherite ingots can be used as the fuel for a beacon. Weird flex but ok.

Advancements

Piglins and hoglins are now required for Monster Hunter and Monsters Hunted

Hoglins

Hoglins are big aggressive beasts that live in crimson forests in the nether
They attack players on sight, so be careful, they can easily knock you off a ledge!
Hoglins drop pork and sometimes leather, but not willingly
You can breed hoglins by feeding them crimson fungi, but do so at your own risk
Hoglins get hunted by piglins sometimes, but they don't go down without a fight!
Despite this, hoglins and piglin aren't enemies - they are more like an ecosystem
Baby hoglins like to pretend they are tough - but don't worry, they are more like angry puppies with no teeth
Want to keep hoglins off your back? Pro tip: Hoglins hate the smell of warped fungi!

Piglins

Piglins are an aggressive civilization that live in the nether
They mostly hang around in the crimson forest, but you might find some in the nether wastes too
They think of players as target practice and will attack on sight
However if you dress appropriately they will see you as a respectable figure, or tolerable at least
Piglins are suspicious of strangers and if they see you opening a chest, or mining a block of gold, they will assume that you're stealing and will treat you accordingly
Piglins LOVE gold and get very distracted by gold items
Gold ingots are currency to piglins and you can throw ingots at them or right-click them with an ingot to barter for various goods
Piglins sometimes get hungry and hunt hoglins for food. Or they try at least. They results... vary.
Piglins prefer to hunt and fight in groups, and when a fight is happening everyone wants in
Piglins that somehow end up in the overworld become zombified fairly quickly
Piglins are creeped out by soul fire and zombified piglins, and will stay clear whenever possible
Wither skeletons are a historic enemy and piglins will attack on sight
Baby piglins are not as dangerous, but they can be mischievous so watch your back
... and they like to play with baby hoglins
