Minecraft’s Nether Update has arrived

The long-awaited Nether Update has arrived for Java Minecraft

It’s finally here: Mojang Studios has released the Nether Update for Minecraft Java, meaning there’s a whole dimension’s worth of weird new stuff to find and experiment with. And possibly run away from, screaming. The Nether Update does very much what it says on the label, namely, updating the kind of stale Nether biome to make it a frightening yet fascinating area once again.

The Nether now comprises four distinct biomes: there’s the Basalt Deltas, the Crimson Forest, Soulsand Valley, and Warped Forest. These are inhabited by Hoglins, Piglins, Zoglins (!), and Striders – all new mobs that you’ll be able to find in the game.

“Fight your way through hordes of Piglins… Or don’t!” writes Java edition producer Adrian Östergård in a brief introduction to the patch notes. “They’re actually pretty cool if you bring some bling.” Of course, he means gold – you’ll want to have some of that on hand if you want to be friends with these new, tusky creatures. “And in case you find yourself in the wrong end of a bargain, make sure that you have access to a functional respawn anchor. I advise you not to use your regular bed unless you’re feeling a bit… ‘adventurous.'”

  • Explore, loot, and conquer a bastion remnant to call it your home – but beware! Piglins don’t take kindly to intruders stealing their possessions

Some blocks have been renamed. Turns out singular fungus in the Nether attempted to falsely present itself as many fungi – so sneaky!

  • As an example, if you were in Survival, then toggled to Spectator and back, you would be set back to Survival


  • Farmers can now put excess seeds in the composter to create bone meal
  • Bone meal is used by the farmers to grow crops

  • Release F3 to apply
  • Your last game mode is remembered and will be the first selected option, so you can quickly toggle between two game modes with a single press of F3 + F4!


We’ve made some changes to hoes to make them more useful in the Nether.

  • Each tier has different speed at which hoes mine blocks they are effective against
  • Hoes can now be enchanted with the following enchantments: Efficiency, Fortune, Silk Touch
  • Those enchantments can now be provided through enchanting table
  • Hoes are now the appropriate tool for mining hay, targets, dried kelp blocks, leaves, Shroomlights, Nether wart blocks, warped wart blocks, sponges, and wet sponges.


  • Hoglins are big aggressive beasts that live in crimson forests in the Nether
  • They attack players on sight. 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. 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 Piglins aren’t enemies – more like an ecosystem
  • Baby Hoglins like to pretend they are tough – but don’t worry, they’re more bark than bite
  • Want to keep Hoglins off your back? Pro tip: Hoglins hate the smell of warped fungi
  • Hoglins that somehow end up in the Overworld become Zoglins fairly quickly – but who would ever bring a Hoglin to the Overworld?


A new block that can help you get your bearings!

  • Crafted from a Netherite ingot and chiseled stone bricks
  • Use a compass on a lodestone to create a lodestone compass, which will point to that lodestone


  • Players can no longer mount another entity when the crouch key is held down
  • Added gamerule universalAnger (disabled by default), which makes angered neutral mobs attack any nearby player – not just the player that angered them. Works best if you disable forgiveDeadPlayers
  • Added gamerule forgiveDeadPlayers (enabled by default), which makes angered neutral mobs stop being angry when the targeted player dies nearby


  • If this gamerule is disabled, then angered mobs will stay angry even if the targeted player dies
  • If both forgiveDeadPlayers and universalAnger are enabled, an angered neutral mob will stop being angry when their target dies. They won’t seek any new targets after that
  • Notable exception: Angered Zombified Piglins continuously spread anger. So even if one Zombified Piglin stops being angry because its target died, other angered Zombified Piglins nearby are likely to make it angry again. The only way to stop the anger is if none of the angered Zombified Piglins see a player for a while


Updated anger management for most neutral mobs (polar bear, wolf, bee, Enderman, Piglin, Zombified Piglin).

  • When hurt by a player, the neutral mob will target that player and try to kill it
  • The mob will stay angry until the player is dead or out of sight for a while
  • Anger is persistent, so a player can’t escape by temporarily logging out or switching dimension
  • If a targeted player dies near the angered mob, it will stop being angry (unless forgiveDeadPlayers is disabled)
  • Neutral mobs also get angry at other mobs who hurt them. However, that anger is not persistent
  • Angered neutral mobs will only attack the offending player, not innocent bystanders
  • Notable exception: If a beehive or nest is broken, the bees will be angry at all nearby players
  • Some mobs spread anger (wolf, Zombified Piglin, Piglin, bee). If a player attacks one, all nearby mobs of the same type will get angry at that player


Universal anger is basically guilt by association. A neutral mob attacked by players will be angry at players in general, regardless of who attacked them. More specifically:

  • A neutral mob attacked by a player will target the nearest player, even if that player wasn’t the attacker
  • Every time the neutral mob is hit by a player it will update its attack target to the nearest player
  • Players can use this to make neutral mobs attack other players. Who would ever do something that devious?
  • Universal anger does not apply when a neutral mob is attacked by another mob – only when it is attacked by a player
  • Universal anger is persistent. The angered mob will stay angry even if the player logs out and logs in, or jumps through a portal and back
  • Mobs that spread anger will also spread universal anger. So if a player attacks a Zombified Piglin, all other Zombified Piglins within sight will be universally angry and attack their nearest player
  • An angered neutral mob will stop being angry if it can’t see any eligible target for a while


  • Zombie Pigmen are now known as Zombified Piglins, and they now have ears. Well, at least one ear
  • Zombified Piglins no longer attack innocent bystanders (unless you enable gamerule universalAnger)
  • Zombified Piglins stop being angry if the targeted player dies nearby (unless you disable gamerule forgiveDeadPlayers)
  • Zombified Piglins continuously spread to other Zombified Piglins, as long as they see their target


  • Biome fog color smoothly blends between biomes. Smooth!


  • A new high-level material found in the Nether. Use it to upgrade your diamond gear!


  1. Mine ancient debris in the lower depths of the Nether. At your own risk though. No insurance coverage for that
  2. Refine it into Netherite scrap in a furnace or blast furnace
  3. Combine four Netherite scrap with four gold ingots in a crafting table to make a Netherite ingot
  4. Use a smithing table to fuse the Netherite ingot with your diamond weapon, tool, or armor


  • Netherite items float in lava – just 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
  • Netherite blocks can be used as the base of a Minecraft beacon
  • Netherite ingots can be used as the fuel for a beacon. Weird flex but ok
  • …and it looks cool!


  • Changed ambient block lighting in the Nether for parity with Bedrock edition


  • Parrots imitate hostile mobs less often
  • Parrots do not randomly imitate hostile mobs when gamemode is on peaceful


  • Piglins are an aggressive civilization that lives in the Nether
  • They mostly hang around in Crimson Forests, 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. If they see you opening a chest or other container, they will assume that you’re stealing and will treat you accordingly
  • If Piglins hear you break a chest or a block of gold (or similar), they will also assume you are stealing
  • Piglins LOVE gold and get very distracted by gold items
  • Gold ingots are currency to Piglins. 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. 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 avoid them if possible
  • Wither skeletons and Withers are historic enemies of the Piglins and will be attacked 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
  • Added a Piglin banner pattern that can be found in bastion remnants


The blockstate, rendering, and behavior of redstone wire are more in line with each other. Redstone will provide power to blocks on all sides it shows a visual connection to, and not do so on those sides without a visual connection.

  • A dot of redstone will not power its surrounding blocks
  • A single redstone wire is now represented as a cross
  • A wire on top of a block, which is redirected from below, will now power the sides it is redirected to. E.g. a fence gate above the redirecting wire will be powered
  • Wires that redirect upwards to wires on non-conductive blocks used to only be redirected visually. Now, this redirection applies to their behavior as well
  • A wire that is redirected to go over a block will now always provide power to the block. This is most noticeable when the wire has signal strength 1
  • When right-clicking a single piece of redstone, it will toggle between a the cross and the dot


  • The target block now conducts redstone signals


Shattered remains of ancient Nether portals. Wonder who built them?

  • They can be found in any Overworld or Nether biome
  • Some are hidden underground, under the sea, or buried in sand


Never suffer again drudging through Soul Sand Valleys – Soul Speed has you covered!

  • Shine your boots of choice with this soul-sucking enchantment to speed around on soul sand and soul soil
  • However, there’s a downside: enchantments will slowly degrade your boots each soul block you walk on
  • Can only be obtained by bartering with those pesky Piglins


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


  • Ghasts sounds are now heard at shorter range

  • New ambient sounds for the Nether biomes
  • New mood detection algorithm for cave sounds
  • Added a new music disc titled “Pigstep” by Lena Raine, which can only be found in bastion remnants


A new mob living the lava lakes of the Nether.

  • Strides on top of the surface of lava
  • Can be saddled, but has a will of its own
  • Really likes the smell of warped fungi – might even be convinced to follow it


Because let’s face it, your aim could use some practice!

  • The closer you hit to the center, the larger the redstone signal
  • Test your skills with a variety of projectiles, including eggs, snowballs, tridents, and more
  • You will need one hay block and four redstone for this recipe


  • Villagers no longer try to work at the same workstation
  • The most experienced nearby villager for the profession corresponding to the workstation you add will get the workstation
  • Villagers now have to walk to and reach the workstation before they can acquire the profession and/or work there
  • Villagers can no longer claim workstations or professions during raids or night time
  • Villagers will check and make sure their workstation is valid at all times of day as long as they are within 16 blocks of their workstation


Warped Forests can now be found in the Nether!

  • Warped nylium carpets the cave floor with all kinds of strange new vegetation
  • Warped nylium can be bonemealed to get more of the strange new vegetation
  • Huge warped fungi make up the “trees” of this forest, with Shroomlights lighting up the forest floor
  • Warped wart blocks can be cleared quickly using a hoe
  • A dark blue fog covers the forest
  • Warped spores swirl through the air
  • The Warped Forests are strange, but also the least hostile place in the Nether


  • Weeping vines are now climbable!


  • The old Nether biome is now called Nether Wastes
  • Shipwrecks and ocean ruins are now a bit less common, so you get more excited when you find one!
  • Patches of blackstone and gravel now generate in all Nether biomes, and patches of soul sand now generate in Soul Sand Valleys


  • Zoglins are zombified Hoglins – the result of bringing a Hoglin into the Overworld
  • Unlike Hoglins, they can’t be bred or fed, and they don’t care about warped fungus
  • Beware – these beasts are raving mad and attack just about everything they see!


  • Added target_hit advancement trigger

Entity checks in triggers can now use loot table condition syntax. Old notation: “`json { “trigger”: “minecraft:playerkilledentity”, “conditions”: { “entity”: { “type”: “minecraft:blaze” } } } “` is now equivalent to: “`json { “trigger”: “minecraft:playerkilledentity”, “conditions”: { “entity”: [ { “condition”: “minecraft:entity_properties”, “predicate”: { “type”: “minecraft:blaze” }, “entity”: “this” } ] } } “` Note 1: Like in loot tables, all conditions in top level array must be met for whole condition to trigger. Note 2: To access new functionality, top level element must be JSON array. JSON object are interpreted as old notation.

Full list of extended triggers:

  • Soulsand with a rail on top will no longer slow down minecarts


BlockStates in Sections elements no longer contain values stretching over multiple 64-bit fields. If number of bits per block is not power of two (i.e. single 64-bit value can’t fill whole number of blockstates) some bits will not be used. For example, if single block state takes 5 bits, highest 4 bits of every 64-bit field will be unused. That also means slight increase in storage size (in case of 5 bits, from 320 to 342 64-bit fields).


  • minecraft:climbable is now a block tag that allows datapacks to determine which blocks are, well, climbable
  • minecraft:soul_speed_blocks is any block that the soul speed enchantment increases speed on



  • style.hoverEvent parameter now has parameter contents, with contents depending on type:

  • For show_entity – object with fields: id (UUID), name (chat component), and type (entity type resource location)
  • Old style value argument is now deprecated (but still supported)



Adds modifies attribute on single entity. Possible syntax: Parameters:

  • attribute base set – sets base valye
  • attribute base get [] – get base value
  • attribute modifier add add|multiply|multiply_base – adds modifier (fails if modifier is already present)
  • attribute modifier remove – removes modifier
  • attribute modifier value get [] – get value of modifier
  • target – single entity (note: only players, armor stands and mobs have attributes)
  • attribute – name of attribute (like minecraft:generic.max_health)
  • name – string (in optional quotes) describing human-readable name of modifier
  • value – floating point value (note: certain attributes have limits on final value, so your change might not be noticeable)


New command that locates a specified biome. Useful in creative mode when you’re looking for a specific biome and don’t want to fly around randomly searching for it. Syntax: locatebiome Parameters:

  • biome – The id of the biome to find


The spawnpoint command now supports being run in any dimension.


Added an optional argument to specify maximum height. New syntax: spreadplayers <center> [under ]

  • maxHeight – Specifies the maximum height for resulting positions


UUIDs stored in NBT are now represented as an array of four integers. Example: {UUID:[I;1498693494,1027158888,1898994005,860320107]} Along with that a couple of fields have been renamed:

  • OwnerUUID of tamed animals, area effect clouds, evoker fangs and projectiles is now simply Owner
  • TrustedUUIDs of foxes is now Trusted
  • target_uuid of conduits is now Target


  • Added experimental support for new custom worlds
  • Edit world screen now has an option to export world settings to a JSON file
  • During world creation you can import previously exported world settings
  • A bunch of new parameters are exposed, but marked as experimental, meaning you can play with them, but there is no guarantee that any of them will continue working (even in the next snapshot!)
  • Flat level preset string lost structure settings (they are now stored in a common format for all worlds), we will restore some form of this functionality soon
  • Buffet world can no longer be created from server.properties, flat level settings changed a bit; better support for custom world creation on the server is coming soon


  • Data packs can now be selected before world is created
  • “Re-Create” option will also copy data packs present in source world


  • If datapack reload fails, changes will not be applied and game will continue using previous data
  • If existing datapacks prevent world from loading, game will give option to load world in safe mode, which loads only vanilla datapack
  • Changes to datapack list are stored only after successful reload
  • Added –safeMode option to server to load only with vanilla datapack
  • Game will now detect critical datapack issues, like missing required tags and prevent world from being loaded


  • Increased view distance in lava slightly while having the fire resistance effect


It is now possible to control at what range the server sends data about entities to clients.

  • Added an entity-broadcast-range-percentage server property controlling how close entities need to be before being sent to clients. Higher values means entities are visible further away from players but cause more network traffic. Specifies percentage of default value, so for example 50 specifies half of the default range


  • Force Unicode option now switches between normal and alternative font (called uniform.json) – no reload needed



Region files are now opened in synchronous mode to prevent data loss and corruption after crash. For performance reasons this feature is disabled by default on non-Windows clients. Status of this feature can be manually controlled by following options:

  • For dedicated servers: sync-chunk-writes within server.properties
  • For clients: syncChunkWrites within options.txt

It is now possible to monitor the server tick times though JMX. The rationale for this is that JMX is a well known and supported monitoring technology with existing integrations and tools. This enables server admins to hook alerts and graphing tools using ordinary JMX clients and dashboards.


  • A new flag enable-jmx-monitoring has been added to the server.properties file which if set to true will expose an MBean with the Object name net.minecraft.server:type=Server and two attributes averageTickTime and tickTimes exposing the tick times in milliseconds
  • In order for enabling JMX on the Java runtime you also need to add a couple of JVM flags to the startup as documented here



  • Added fishing_hook sub-predicate


Check properties of the fishing hook
