Java Edition 1.9

 will be the first non-development version of the Combat Update, which 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

 * World selection screen
 * Worlds now display the version they were last played in, or "< 1.9" if the last version was before 1.9.

Gameplay

 * Dominant hand option
 * An option for players to change their dominant hand on their player model.
 * Also changes the orientation of the offhand slot in the hotbar.
 * Dual wielding
 * Players can now use both hands at the same time to do different actions, with the left and right 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 left 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 off-hand slot is displayed next to the hotbar when it's not empty (left for right-hand players and vice versa) and it's also available in the inventory screen.
 * Only the main hand can be used for attacking.
 * Bows can be used even when something is in the other hand.
 * The other hand is invisible in first person view while it's empty.
 * Some attributes and enchantments will apply to the off-hand 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 except for the last two:
 * Effect level 255 results in neither floating up nor down.
 * Effect level 254 results in slow fall (similar to lunar gravity).
 * Received when players or mobs are hit by spectral arrows.
 * Makes player's outline glow, seen even through non-transparent blocks.
 * Listed as a negative effect because it prevents you from hiding from players once you are hit.
 * It becomes colored differently, if the player is part of a team to match the team color.
 * This makes it useful in a variety of multiplayer maps.
 * It becomes colored differently, if the player is part of a team to match the team color.
 * This makes it useful in a variety of multiplayer maps.

World generation

 * End City
 * Generates on separate end islands, arranged around the main island in a toroidal configuration (donut-like).
 * Dungeon-type structure fashioned like a branching tower made of endstone and many of the new blocks.
 * Resemble a tree house.
 * End ships
 * Spawns right next to the end city dungeon.
 * Composed of the same materials.
 * Spawns with shulkers in it.

 * Chorus trees
 * Tree-like arrangements of the new chorus plant and chorus flower blocks.
 * The whole structure is destroyed when the bottom-most block is destroyed, like cacti.
 * Can be farmed by planting the chorus fruit flowers that come from the top of the plants.
 * Unlike cacti, chorus plants do not require the supporting block to be below it, but rather adjacent.
 * This allows the structure to grow around obstacles, like other plants.
 * End Gateway Portal
 * A small structure consisting of an end gateway block and two little bulbs of bedrock, at both the bottom and the top.
 * It is an alternative way of traveling to the outer end islands, without having to build or fly all the way over there.
 * Since the bulbs of bedrock only leave a one block slit on the horizontal plane, it is only accessible by using ender pearls, or by riding pigs, boats or minecarts.
 * The player will get teleported to somewhere on the outer end islands
 * The final location of the player depends on what angle he/she entered or at what angle the enderpearl was thrown at.
 * One of them is created for each dragon kill and up to 20 are possible.
 * Placed in a radius around the end portal.
 * Another one is also created everytime the player teleports to a new location, so both gateways are linked, and the player has a way back.

 * When attacking, it opens its shell on a spinning animation, revealing the creature inhabiting.
 * The creature looks a like a little white cube with big eyes
 * Its attack consists in shooting projectiles
 * The projectiles chase the player until it's out of range, but they can only move along one of the three grid axes at a time.
 * This means they can only move through taxicab geometry.
 * Projectiles can be knocked away by attacking them.
 * Getting hit by a projectile causes 2 hearts of damage and inflicts the levitation status effect.
