New features

Axolotl

• Axolotls are amphibious creatures that spawn in underground water
• Holding a Bucket of Tropical Fish will cause nearby Axolotls to follow the player on both land and in water. Axolotls cannot be tamed but can be bred by feeding them Buckets of Tropical Fish.

• Axolotls come in a variety of colors, all with an equal chance of spawning except for blue. Blue Axolotls have a small chance of spawning as a mutation when breeding two Axolotls
• Axolotls can survive on dry land for a few minutes. After that, they will start to dry out and take continuous damage until rehydrated
• When taking damage, there is a chance that the Axolotl will play dead. While playing dead, the Axolotl will regenerate health and mobs will be unable to target the Axolotl.
• When a player kills a mob that the Axolotl was attacking, they are rewarded with the regeneration effect, and their mining fatigue is removed, if they had it
• Axolotls can be picked up with buckets, just like Fish!

Dripstone blocks

• Decorative block
• Can be crafted with four Pointed Dripstone

Pointed dripstone

• Forms a stalactite if placed on the ceiling or a stalagmite if placed on the floor
• Can be combined to form longer stalactites & stalagmites
• Stalactites and stalagmites merge if the tips are next to each other unless you press shift while placing
• Stalagmites will break if they're not attached to something below
• Landing or jumping on a stalagmite hurts! They are sharp
• Stalactites fall down if not attached to something above
• Being hit by a falling stalactite hurts! They are sharp
• Stalactites drip water (or lava if there is lava above the ceiling)
• A stalactite with a water source above the ceiling will gradually fill a cauldron below with water
• A stalactite with a lava source above the ceiling will fill a cauldron below with lava after a while
• Thrown Tridents break Pointed Dripstone

Dripstone growth

• If a stalactite is hanging from a Dripstone Block with a water source above, it will slowly grow both the stalactite from above and a stalagmite from below
• Growth speed is random but very slow, a single growth step can take several Minecraft days
• A stalactite will only grow up to seven blocks long
• A stalactite will only cause stalagmite growth if the floor or stalagmite below is within 10 blocks
• If the stalactite tip is inside water it won't drip, and therefore won't trigger any growth
• If the stalagmite tip is inside water it won't receive drops, and therefore won't be grown by a dripping stalactite. Same thing if there is any fluid between the two tips.
• A stalagmite or stalactite will never grow into a fluid

Glow lichen

• A dim light source that generates in caves
• Use Shears to pick it up
• Use Bone Meal to spread it along block surfaces

• When killed, Glow Squids drop Glow Ink Sacs
• Glow Ink Sacs can be used on Signs to make the text super visible, even at night. Works with colors!
• Craft a Glow Item Frame by combining a Glow Ink Sac with an Item Frame in a Crafting Table. Any item in a Glow Item Frame is perfectly illuminated, even at night.
• Use an Ink Sac on a Sign to remove the glow effect
• Axolotls will attack any Glow Squids they see, so… be careful
• Glow Squids spawn in underground water that is in total darkness with Stone, Granite, Diorite, Andesite, Tuff, or Deepslate below

Goat

• Goats spawn in mountains
• Goats can scale the sides of mountains with their incredible jumps
• Goats can be tempted and bred using Wheat
• Goats are another source of Milk!
• Goats will ram anything that moves… also Armor Stands

• Mobs rammed by Goats do not retaliate

Infested blocks

• Infested Blocks are no longer instantly destroyed, and instead, have half the destroy time of their non-infested counterpart

Lightning rod

• A Lightning Rod is crafted from three Copper Ingots
• Keeps your builds safe (well, as long as the closest area around the Lightning Rod is fireproof) during thunderstorms!

• Glow Berries are a natural light source as well as a food source
• Foxes eat Glow Berries
• Use Glow Berries to plant new Cave Vines
• Bonemealing a Cave Vine will create Glow Berries

Drip leaves

• Small Dripleaf needs moisture, so it grows on Clay or underwater
• The facing direction of Small Dripleaf blocks is determined by which direction the player is facing when placing it
• The Wandering Trader will sometimes sell Small Dripleaf plants
• Small Dripleaf grows into Big Dripleaf when bonemealed
• Big Dripleaf grows taller when bonemealed
• If you stand on a Big Dripleaf, it will tilt after a while, and you will fall off
• A tilted Big Dripleaf will tilt up again after a while
• A Big Dripleaf will tilt when hit by a projectile
• A Redstone powered Big Dripleaf will not tilt (except when hit by a projectile)

• There are four stages: Copper, Exposed Copper, Weathered Copper, and Oxidized Copper
• It takes 50-82 Minecraft days (in loaded chunks) for a Copper Block to oxidize one stage
• Waxed Copper Blocks will not oxidize
• You can wax any oxidation stage – how lovely, that means you can keep that pretty Weathered Copper Block in its weathered stage forever!
• A lightning strike hitting Copper will clean its oxidation
• Waxed Copper Blocks can be crafted into nine Copper Ingots
• Axes can scrape off wax and oxidation from Copper Blocks

Smeltable ore drops

• Ores that are smeltable now drop raw item forms of the ore instead of the ore block, and these can be smelted just like before
• This is to prevent cluttering the inventory, and have consistency with Fortune on all ores
• Just like other ore materials, you can craft a compact version with raw ore items in order to save inventory space

Smooth basalt

• Smelt Basalt to obtain Smooth Basalt

Spyglass

• You can use a Spyglass to see faraway things
• Pretend to be a sea captain, or catch your neighbor in the act as they dye your Sheep lime green

  • When this option is used, players will be prompted for a response and will be disconnected if they decline the required pack
  • If user has a setting to automatically decline packs, the prompt will still be shown (since the alternative would be automatic disconnection)
• A dedicated server can also configure an additional message to be shown on the resource pack prompt (resource-pack-prompt in server.properties, expects chat component syntax, can contain multiple lines)

• This type of file can contain a single function (i.e single JSON object) or an array of functions

Java 16

Light block

• Op-only (/give), air-like, waterloggable block
• Emits light at a level that is determined by block state
• Visible and targetable only when an item is held (similar to Barrier Blocks)

set_damage function

• This function now has an add parameter. If true, the change will be relative to the current damage. If false, the damage will be replaced with the current value (default behaviour)

value_check condition

• Parameters:
  • value - see "New value providers" section (currently a combination of random generators and score)
  • range - min / max range

set_banner_pattern function

• Sets tags needed for banner patterns

  • add - if true, the change will be relative to the current level. If false, the level will be replaced with the current value (default behaviour)

score value provider

• Returns scaled scoreboard value
• Parameters:
  • score - scoreboard name
  • target - see below
  • scale - scaling factor (float)
• Scoreboard provider targets:
  • <target> or {"type": "context", "target": <target>} where <target> can be one of this, killer, direct_killer, killer_player (not all may be available depending on context)
  • {"type": "fixed", "name": "<scoreboard name>"} for fixed scoreboard name (may be fake player)

Markers

• Markers are a new type of entity that is meant for custom use cases like map-making and data packs
• Only exist on the server-side, and are never sent to clients
• They do not do any updates of their own
• They have a data compound field that can contain any data

OpenGL

• Rendering is now using OpenGL 3.2 core profile. All fixed-function rendering has been replaced with shader-based rendering
• Shaders are now included for all supported render states. Any shader, except for the blit shader, can also be replaced in resource packs. For now, replacing these shaders is not officially supported, and the way it works may change in the future
• The current rendering engine uses a system similar to the post-processing shader pipeline. There are some differences between both systems that cater to the slightly different requirements

Particles

• Added new particle types called vibration and dust_color_transition

Performance metrics reporting

• These will be saved to a zip file in debug/profiling/<yyyy-MM-dd_HH.mm.ss-[levelname]-[version]>.zip and could be used for performance regression analysis if included in bug reports
• The exact metrics, output format, and names are susceptible to change between versions. Our plan is to continue iterating on which metrics to capture
• Pressing F3+L while in the game will start a recording for 10 seconds, which captures metrics such as tick durations, used heap sizes, and other more detailed stats
• Pressing F3+L before the 10-second limit will end the recording early
• This shortcut is always available to clients, even on multi-player servers where it will record client-side performance
• perf start will start a recording for 10 seconds, which captures metrics such as tick durations, used heap sizes, and other more detailed stats
• perf stop before the 10-second limit will end the recording early

Resource packs

• Changes to resource packs for version 7:
  • Drowned texture mirroring has changed
  • The slots for the Game Mode Selector are now 26 pixels instead of 25

Server properties

• Removed max-build-height

Statistics

• The statistic for play time has been renamed to play_time
• There is now a statistic for "Time with World Open" (total_world_time) that also includes time when the game was paused
