Java Edition 1.9

, the first release of the Combat Update, is an upcoming major update to Minecraft with no set release date. Dinnerbone has stated that many of the features he has shown for 1.9 are not “100% final”, so things may change later.

General

 * Splash text
 * "More Digital!"
 * World selection screen
 * Worlds now display the version they were last played in or "unknown" if the version was older than snapshot 15w32a.
 * The version number will display in red if it has been played in a newer version before.
 * Now displays a thumbnail per world, showing a glimpse of the world (it takes a screenshot when you have just created or opened it for the first time in the 15w32b snapshot or higher).
 * When the world hasn't been opened in snapshot 15w32b or before, or if the game couldn't make a screenshot thumbnail, there will be a gray-scale image.
 * The thumbnail will be saved in the world folder under  with the name "icon.png".
 * This allows the player to modify it easily and safely.
 * An exclamation mark will appear on top of the thumbnail, indicating that the world has not been played in the current snapshot yet.
 * It displays a message when hovered over: "Don't forget to backup this world before you load it in this snapshot."
 * It will also warn if a world was played in a newer version of minecraft, telling the player that the world may corrupt if they open it in an older version.
 * The player can now click the play arrow on the thumbnail to open the world, just like the server list.
 * When edit world is clicked, you have two new options
 * Reset icon: This allows you to reset the thumbnail without going into the folder
 * Open folder: It will open the folder for the world, under.
 * Dominant hand option
 * An option for players to change their dominant hand on their player model.
 * A toggle under "Skin Customization".
 * Also changes the orientation of the offhand slot in the hotbar (left for right-hand players and vice versa).
 * Statistics
 * : Tracks the amount of ticks the player has held the key, regardless if the player was moving.
 * : Tracks the amount of items that are picked up into the inventory from the ground.
 * : Tracks the amount of items that are dropped from the inventory to the ground.
 * Pick block
 * In survival, pick block now works on items outside the hotbar as well.
 * In creative, picking a block will give you a new one instead of existing ones with NBT data.
 * + no longer replaces items.
 * Existing items are put into the inventory instead of being deleted.
 * Keyboard shortcuts
 * + to toggle between creative and spectator mode, if the player is in either of them.
 * The player needs to be OP in the case of servers for this to work.
 * + to show a statistic of FPS.
 * Particles
 * Used for the defensive sword attack.
 * dragonBreath
 * endRod
 * wake
 * wake

Gameplay

 * Dual wielding
 * Players can now use both hands at the same time to do different actions with the left and right mouse buttons.
 * For example, if a player has a pickaxe in his/her main hand and a torch in their other hand, right clicking will place the torch.
 * This happens because because a pickaxe lacks a right click use, and therefore the game tries to then treat the other item as if it's being right clicked.
 * The player cannot click both buttons at the same time.
 * This is achieved through an extra inventory slot called the "offhand" slot.
 * Pressing (by default) will switch whatever item is selected in the hotbar with the item in the offhand (including no item).
 * The offhand slot is displayed next to the hotbar when it's not empty (left for right-hand players and vice versa).
 * It's available on the main inventory screen.
 * It is distinguished by an outline of a shield like symbol.
 * Only the main hand can be used for attacking.
 * Even bows can't be used while in the offhand.
 * Bows can be used when something else is in the offhand.
 * Arrows in the offhand take priority over arrows in any other slot.
 * If there are multiple arrow types and none in the off-hand, the arrow closest to inventory slot 0 will shoot first
 * The offhand model is invisible in first person view while it's empty.
 * Some attributes and enchantments will apply to the offhand item, while others will not.
 * Status effects
 * Received when the player is hit by shulker projectiles.
 * Makes player involuntarily float high into the air.
 * Can be used to get to higher places.
 * Listed as a negative effect due to the potential to kill from fall damage.
 * Higher levels of levitation result in faster floating.
 * Effect levels 128-254 result in floating downwards at a constant speed, with level 128 being the fastest and level 254 the slowest (one block per second).
 * Effect level 255 disables falling and jumping altogether, to an effect not entirely unlike flying in creative mode. Gaining or losing elevation is impossible without using pistons.
 * Received when players or mobs are hit by spectral arrows.
 * Makes player's outline glow, even through non-transparent blocks.
 * Listed as a negative effect because it prevents players from hiding from other players.
 * It becomes colored differently if the player is part of a team to match its team color.
 * Listed as a negative effect because it prevents players from hiding from other players.
 * It becomes colored differently if the player is part of a team to match its team color.

Command format

 * Scoreboard
 * Added
 * The player can add and remove tags for any entity based on NBT tags of that entity/player.
 * For example  will add the tag "test" to all players that are in the air.
 * Tags can be accessed by using the parameters after the selector;  will give 1 stone to all players that have the tag "test".
 * The player can use  to see what tags are on an entity.
 * Tags are stored in the  file as strings, not in the scoreboard files.
 * This means that any tag the player binds has to be bound to an existing online player or an existing entity.
 * Unlike objectives, tags cannot be displayed anywhere on the HUD or inventory.
 * Only via the list subcommand can the player see which tags an entity has on the chat.
 * Through  it is possible to obtain the number of scoreboard tags an entity has via.
 * Added five new objective types: XP, hunger, oxygen, armor and level.
 * "xp" can be used to track the players exact amount of XP points.
 * "food" can be used to track the hunger level of the player (ranges from 0 to 20).
 * "air" can be used to see how long the player has been underwater.
 * Starts at 300 (out of water) and then decreases 1 per tick as long as the player´s head is underwater (resets when the player gets out of the water).
 * The water breathing status effect freezes the timer and the respiration enchantment slows down the countdown from 300, each time more with each level.
 * "armor" can be used to track the armor bar, which in turn tracks the total amount of protection of all currently worn armor pieces.
 * "level" can be used to track the player's level directly, which is the number displayed above the experience bar.
 * It is not directly correlated to the experience, since increasing levels each time takes more xp than before.
 * This could be done before, but it required some intermediate steps.
 * Added
 * Subcommands:,  ,  ,
 * NBT tags
 * All entities
 * (byte): Controls whether or not an entity is affected by the new glowing status effect.
 * (list): Contains a list of string values that can be used with the "tag" selector parameter. The command can assign tags itself.
 * All mobs
 * (lists): Defines what item is within the mainhand and offhand. Contains two records, the first record is mainhand while second is offhand.
 * (lists): Used to specify the armor worn by the mob. Contains four records, the order is: feet, legs, chest, head.
 * (byte): Boolean tag that controls the dominant hand of mobs. When set to 1, states the mob's mainhand is the left hand rather than right hand.
 * &  (lists): Used to specify the dropping chances of worn armor and held items of specific mobs respectively.
 * All items
 * string tag within  (string): Determines which slot the modifier is applied to.
 * Available slots are: "mainhand", "offhand", "feet", "legs", "torso", "head".
 * End gateway portal block
 * (compound): Holds a set of X/Y/Z coordinates to determine the general location the player will be "safely" teleported to when entering.
 * (byte): When set to 1 teleports entities to the specified coordinates exactly instead of at a safer location around those coordinates.
 * (long): Determines how long the gateway has existed. When lower than 200, the block will emit a purple beam.
 * Command blocks
 * (byte): All command blocks now have the "powered" tag associated with them, stating whether or not the block is currently receiving a redstone signal. While it can be detected for all command blocks, only the "chain_command_block" can functionally have theirs changed to 1.
 * (byte): When set to 1, the command block will no longer require a redstone signal in order to activate. When applied to an Impulse block, its command will activate once. When applied to a Repeat block, it will activate every tick as expected. When applied to Chain blocks, they will not require a redstone signal to activate their command.
 * (byte): States whether or not the command block behind the conditional command block was successful in output. Will be 1 if that block is successful and 0 if unsuccessful. Non-conditional command blocks will always be 1.
 * Zombies
 * (integer): Specifies the profession the zombie villager will be presented as, as well as become when cured.
 * Shulker

 * (byte): Determines the direction the shulker has attached to a block. Summoning shulkers by default will make it attach accordingly, but you can change it manually.
 * (int): Set of exact coordinates that the Shulker should be located at. Shulkers mimic blocks, so this is used to keep them within an exact block space. Summoning with this will override the coordinates in /summon.
 * ShulkerBullet entity
 * Used to control the target location of shulker projectiles.
 * Relevant NBT structure:
 * Potions
 * (string): Used to differentiate a regular potion from both splash and lingering potions and determine the type of potion it is using new name IDs.
 * ThrownPotion entity
 * (byte): When  is set to 1, the potion will create the   entity when it lands.

 * (compound): Holds the item data for the specific tipped arrow.
 * SpectralArrow entity
 * (integer): Specifies how long the effect will last when the arrow strikes the target.
 * Ender crystals
 * (compound): Used to assign a custom target to the location of the beam.
 * Ender dragon
