Java Edition 1.9

, known as The Combat Update, is an upcoming 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.

Gameplay

 * Dominant hand option
 * An option for players to change their dominant hand on their player model
 * Dual wielding
 * 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 when not holding something
 * Key to swap items between hands, which is by default
 * For example, if you have a pickaxe in your main hand and a torch in your other hand, right click places the torch
 * The off-hand slot is displayed next to the hotbar, on the off-hand side (left for right-hand players and vice versa)
 * Some attributes and enchantments will apply to the off-hand item, while others will not
 * Status effects
 * Levitation status effect
 * Received when 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
 * For example, effect level 255 results in neither floating up nor down
 * Effect level 254 results in slow fall (similar to moon gravity)
 * Hitting the ground still results in the player receiving regular fall damage, if the player had fallen from a high enough elevation.
 * Glowing status effect
 * 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
 * Supports different colors for different teams to allow usage in competitive maps, team co-op maps, etc.
