Java Edition mentioned features

Since the beginning of Minecraft's development, there have been a number of features that were mentioned by Mojang AB developers. These features are either currently planned for the next update, but have not yet appeared in a development version, or have simply been dropped or forgotten about.

Note that this page only documents features that were mentioned, but are not yet in the game. Features in development versions are described on the parent version page.

Planned
These features are planned to come to Minecraft sometime in the future, in an update that has not yet been determined.

Combat changes
A new combat system is currently in development which will only allow the player to attack when their weapon is fully charged among other changes.

Fletching and smithing table functionality
Fletching tables and smithing tables were set to gain functionality in "the next major themed update". However, they may not get their functionality in Java Edition 1.16. The exact usage of these blocks has not been announced.

Biome updates
Desert and savanna were the biomes that did not win the MINECON Earth 2018 "biome chooser" vote. Their features are promised to be added in a yet-unknown future update:
 * Deserts will be given palm trees, oases, and meerkats.
 * Savannas will be given baobab trees, termites, and ostriches.

As a result of the biome vote at MINECON LIVE 2019, the mountains biome will receive new features sometime in 2020 – sooner than the badlands and swamp, but later than Java Edition 1.16.
 * Mountains will be given goats, a new type of snow, and better terrain generation.
 * Badlands will be given vultures, tumbleweed, and a new type of cacti.
 * Swamps will be given frogs, mangrove trees, and a new type of boat.

Super Fancy graphics
Docm77 confirmed in a tweet that sometime in the future, a new graphics setting will be added to Minecraft called "super fancy." This could be in reference to the upcoming ray tracing functionality being added to Minecraft.

Blaze3D


A new Java Edition render engine called Blaze3D has been confirmed many times by Searge. There are also many references to this system in the game files, although it has not been functionally implemented.

Phasing out of NBT-based crafting recipes
In Java Edition 1.14, numerous new blocks were implemented as replacements for certain "complex" crafting recipes, with the replaced crafting recipes relying on NBT data. This included moving inventory tool repair to the grindstone, banner modification to the loom, and map modification to the cartography table. However, several more NBT based crafting recipes still exist, and these are planned to be phased out. Certain blocks that may be added in the future to further this goal include a dedicated fireworks customization block.

In Java Edition 1.14.3, tool repair crafting recipes were reimplemented.

Full split of liquids from blocks
Java Edition 1.13 added waterlogging, marking the start of this separation. An in-development screenshot showing water occupying leaves and flowers, referred to as having "no water blocks", was released in 2018. However, water and lava still exist as blocks, and so far only water sources can occupy other blocks through the waterlogged block state; flowing water and bubble columns cannot occupy other blocks and still and flowing lava cannot occupy other blocks at all.

Having water only occupy one side of a block like a glass pane, but not the other, is also something that has been considered.

Partially implemented
These features had been shown by a Mojang staff member, but either had no further development or were canceled shortly after.

Colored wood planks
Dinnerbone briefly thought about implementing colored wood planks, releasing a test image on his Twitter page. This however never got implemented, as can be seen from the following quotes. The idea was eventually replaced with stained clay.

Dirt slab


Before stone slabs were added to 0.26, Notch ran a test of dirt slabs. In the test, they replaced dirt blocks, so that dirt surface without grass was half a block lower than grass. However, dirt slabs failed to dress cliff edges, caves, and ravines nicely. Because of this, they were never added to the actual game and were only mentioned once. They replaced all dirt blocks and did not grow grass on top.

Sky Dimension


The Sky Dimension was a planned dimension, intended to be the opposite of the Nether. It could be accessed using hacks, but portals to the Sky Dimension were never implemented. The idea was ultimately scrapped    and its code was reused to make the End. The End has a purple sky, no clouds, and the floating island are made entirely of end stone.

With the addition of the Buffet functionality in 1.13 snapshot 18w15a, this can be distantly recreated by using the "Floating Islands" option.

Mentioned
These features were mentioned at one point, but later abandoned or their current status is unknown. Note that some of these features were mentioned by developers who either no longer work at Mojang, or no longer work on Minecraft.

Audio loops
Loops were unused sounds, found in the game files, and were possibly meant for when the player is in a specific type of location (i.e., in caves, forests, the ocean and beside a waterfall).

They were found in, and could be converted to reveal four loops, of birds chirping, cave chimes, ocean and waterfall noises.

Branches
Notch mentioned both of these in a blog post during Indev. The addition of sideways logs seems to be an alternative for branches. Implemented on chorus trees, but not on ordinary trees.

Cave and underground features
Many features relating to the underground and caves have been mentioned historically, but are yet to be seen in-game. An extremely early example of this was crystal blocks, a type of material which could be found in large underground deposits. Later suggestions which were approved by Mojang include rainbow crystalline caves and cave maps, considered "an interesting idea" by Notch.

Friends list
Notch mentioned on his blog, The Word of Notch, that friends lists would be added after Beta 1.8. The Minecraft documentary team of 2 Player Productions filmed a Keynote roadmap, containing these lines. Kristoffer mentioned on Twitter that he is currently working on friends lists for Scrolls, then for other Mojang games. These will be available for players with Mojang accounts. At MineCon 2012 Jeb stated that it would be a large implementation on the server side and will be used for all Mojang games, and that is a big project.

Inventory changes
An inventory rewrite was originally added in the snapshot 14w17a for Java Edition 1.8, but a roadblock was hit and they had to shelve it before the release of 1.8. Other changes to the inventory have been mentioned, including spectators can now look at people's inventory, visible health/armor bar on all players, seeing players' GUI when spectating from their POV and the return of shift-double-clicking.

Lua scripting
Lua Scripting was a feature mentioned by Notch as a way to create server side modifications. The server would be able to create custom commands, assign certain server functions to blocks, and create user groups. Players would not have to download scripts within or outside of the client, and therefore no client-side modifications will be necessary. Notch said that he wanted Lua to be an extension for Minecraft, but did not want Lua to turn Minecraft into a game engine.

Lua scripting has been further hinted at by Searge.

Nether features
Multiple features relating to the Nether have been proposed and acknowledged, such as utilizing the space above the Nether ceiling for something else, non-rectangular nether portals, nether portals placing players in front if possible and a Nether variant of gold ore.

During the development of the Nether Update, other ideas were discussed, such as dyeable nether portals, which were dismissed as not being priority by Jeb, as well as in-game hints on how to access the Nether.

Rare tools/weapons
Dinnerbone said on Twitter he would like to add weapons/tools that cannot be crafted, and only obtained by treasure chests/trading, etc. For example, bows with faster drawback (somewhat implemented with the addition of Quick Charge), boots that increase health, or night vision helmets. However, the attribute system has to be finished first.

Treasure enchantments have been implemented in 1.9 and 1.11, and tridents have been implemented in 1.13, somewhat implementing this feature.

Red dragon
Notch revealed during the 8th Seecret Friday Update that he would add dragons, one being the ender dragon, the other being red dragons. Jeb informed participants of his AMA on Reddit that he would add red dragons, but was unsure exactly how. The red dragon has not subsequently been added.

On October 22, 2013, Dinnerbone tweeted that the red dragon is "shelved" and not in development.

Later, on December 15, 2013, a Dinnerbone post on Reddit indicated his belief that red dragons likely will be implemented at some point:

Resource packs
Erik Broes mentioned that there may be easier customization of chat and sheep colors.

Ryan Holtz stated that he wanted to improve the rendering system to allow for customizable models and animations. Dinnerbone later stated that player models would not be able to be changed.

Seasons
Dinnerbone mentioned on Twitter that he was experimenting with adding seasons, and varying the length of day and night according to season. He also mentioned it during MineCon 2013. Seasons may include changes in color of tree leaves and may also be tied to real time.

Spike block
Spikes received a mention in mid-2009 by Notch in a blog post. These were originally planned for, working by extending and retracting spikes (and making them more "spike pistons" than anything), but were replaced by sticky pistons. On May 28, 2012, Dinnerbone stated that he'd like to add spike blocks, but is unsure of how to implement them.

Steel
Multiple references to steel were made early on in the game's development. Notch had stated that it could be made using coal and iron ore, and that it could be used for armor and weapons more powerful than iron. In-game, the flint and steel is crafted using raw iron.

Workbench (Plugin API)
The Plugin API, dubbed "Workbench", is a feature that allows mod developers to easily add more content to the game. In contrast to mods, plugins will not require any alteration of the minecraft.jar file itself, although they will also be slightly limited in their feature set. The Bukkit team will help make the official Plugin API.

Off-hand changes
Changes with the off-hand slot added in Java Edition 1.9 were planned on being added to Minecraft sometime in the future. Specifically, the player would no longer be able to or place blocks with any item in their off-hand slot. However, players would still be able to hold items in the off-hand slot, which still made the off-hand useful for maps and such. Also, blocking would still be able to be activated if the player is holding a shield in their off-hand. However, this regression was later retracted due to massive community backlash.

Brief mentions
These features were briefly mentioned, but no further information was given after that.

General features

 * More animals such as birds, and tree animals, to make the game seem more alive. Partially added in Java Edition 1.12 with parrots.
 * More structures in biomes Since this was mentioned, woodland mansions, End cities, shipwrecks, underwater ruins, and Pillager outposts have been implemented.
 * More dimensions
 * More rare structures and terrain changes Partially added with Ice Spikes.
 * More ores and cave types Since this post, flooded underwater caves have been implemented. In 1.16, ancient debris will be added to the Nether as a new ore.
 * All exclusive Bedrock Edition features ported to Java Edition. See Official pages/Parity issue list for more info.

More specific features

 * Mentioned in 2009
 * In early development, Notch mentioned two more gamemodes, Team Survival Mode and Fortress Mode, which would include the ability to play Capture the Flag


 * Mentioned in 2010

 * Smoke block: would be generated by fire, be passable, cast shadows, float upwards and disappear after a short time.
 * Gravity: all blocks except possibly obsidian would be affected by gravity. Floating islands would need obsidian veins to stay afloat. Notch later stated that he disliked the idea.
 * More crafting templates: arrows, food, armor, etc. (Possibly added in Java Edition 1.14.)
 * In-game anti-cheat: make the server check for flying, no clip and increased speed. Add those options to the client, but only enable if the server says it's okay.

 * Crystal Horse Armor
 * Dinnerbone's original demonstration of the  format for resource packs contained a sample properties file for fonts to determine character size and spacing.

 * Another rabbit skin
 * Changes to the world format - modularizing and storing in 16 block high sections, ids per chunk Such a feature would likely allow for infinite building height.

 * Using the killer rabbit killing mobs for something.
 * Mesa temple
 * A marker entity.
 * OAuth
 * Reindeer - initially suggested for Christmas 2015.
 * Being able to make the world border's center slowly move


 * Mentioned in 2015
 * Corn
 * In game lore
 * Entities possibly being able to switch between weapons - "There are no plans right now for entities to use that [offhand] slot, but it might be a potential change in the future. It's just cleaner to have generic support for the off-hand slot than adding a special-case the player class only."
 * Making it so shields are used to block attacks from the side the shield is held on.
 * A mob which camouflages with its environment - when developing the Shulker mob, Jeb initially had it so that the mob would camouflage with the surroundings, but due to difficulties with the code and rendering, he decided to abandon this element of the mob, but stated that it may happen in the future.

Joke features


Notch and other Mojang AB employees have frequently joked about adding various features to the game.


 * Searge jokingly stated that due to the fact that people didn't dislike the changes in the 15w42a snapshot, he would add a fuel requirement to crafting tables.
 * Koalas in tanks riding on planes with laser rifles was jokingly added to the "maybe later" list by Searge.
 * Hot dogs.
 * Herobrine. In every new major Minecraft update like Halloween Update, Adventure Update, Pretty Scary Update, Redstone Update, Horse Update, The Update That Changed The World, The Bountiful Update, The Combat Update, The Frostburn Update, The Exploration Update, The World of Color Update, Update Aquatic and Village&Pillage, it says "removed Herobrine", but Herobrine was never implemented. This has also appeared in the changelog for Scrolls version 0.103.0.
 * When Hardcore mode was announced, a joke screenshot of "Ultra Hardcore Mode" was shown, where death would revoke an account's premium status.
 * Jeb joked about adding chips if 100% of the community agreed on what type the chips would be.
 * Jeb joked about adding more types dragons. In response, MissMarzenia joked "DRAGONS CONFIRMED."
 * Marc joked about adding Top Hats for 1.4.
 * A snapshot named 12marc40awesome containing various joke features such as volcanoes, more dragons, coral, fish, and fish blocks. Partially added in Java Edition 1.13 with fish and corals.
 * Pine cones.
 * Dinnerbone joked about adding dwarves when asked about it.
 * A texture known in the game files as "skis.png", was added in the Christmas/New Year update. Its textures were added by Dinnerbone as a red herring.
 * SethBling mentioned a downside of command blocks on one of his livestreams, and Dinnerbone joked about removing command blocks to accommodate him.
 * Dinnerbone joked that Minecraft pizza would be a good idea to add, and as a joke KrisJelbring stated that pizza is confirmed to be added.
 * After the announcement of pillagers, Dinnerbone and Jeb joked about several more villager portmanteaus:
 * Drillager: he comes and pokes holes in things.
 * Fillager: he fixes the previous guys stuff.
 * Thrillager: really likes heights and scary things.
 * Killager: but we kinda already have that.
 * Spillager: prevents you from drinking potions.
 * Stillager: just stands around blocking important doorways.
 * Millager: the only hard working one of the bunch.
 * Krillager: Swims around and gets eaten by whales
 * Mojang has made several April Fools jokes:
 * In 2011, the locked chest or "Steve Co. Supply Crate" was temporarily added which "allowed" various micro-transactions in the game.
 * In 2013, Mojang released Minecraft 2.0 which contained features such as pink withers and redstone bugs.
 * In 2014, the default sounds were replaced with a voice (specifically, that of ElementAnimation, a famous YouTuber group known for making several popular videos about Minecraft) saying the name of the sound's source, the music was replaced with a rendition of the title theme of the TV series Game of Thrones (consisting of the word "door" repeated to the tune of the music), and everyone's skins were replaced with modified versions of the villager textures, edited to fit the player model. This was all blamed on the villagers.
 * In 2015, Mojang released 15w14a, which made all the mobs in the game friendly and loving.
 * In 2016, Mojang released 1.RV-Pre1, which added trendy items of 2016.
 * In 2017, the Mine & Craft Digital Leisure Device was announced on the Minecraft website.
 * In 2018, Mojang released an 8-bit resource pack to 1.12.x and versions from 17w43a to 18w11a clients.
 * In 2019, Mojang released 3D Shareware v1.34, which changed the game's visual style to resemble 1990s video games.
