1.9.1 is an update for Minecraft () released on March 30, 2016. 1.9.1 is not compatible with 1.9 servers. Due to a major multiplayer bug, 1.9.1 was replaced with 1.9.2 on the same day.
==Additions==
===Items===
; Armor
* New armor attribute: generic.armorToughness, which includes a new formula for calculating damage:
*: totalDamage=damage\times(1-\frac{max(\frac{defensePoints}{5},defensePoints-\frac{damage}{2+\frac{toughness}{4}})}{25})
** Increased toughness means less armor defense point reduction from strong attacks.
** Diamond armor has toughness 2, all other armor has toughness 0. A full set of diamond armor, therefore gives a toughness attribute of 8.
; Elytra
* Added sound effects while gliding with elytra.
** Sound event item.elytra.flying.
==Changes==
===Blocks===
;Dispensers
* Dispensers with arrows in jungle temples now use loot tables.
* Increased limit per tick for scheduled tile ticks from 1,000 to 65,536.
; Hoppers
*Can now push and pull items to and from chests that are blocked from opening.
===Items===
; Shields
* No longer take damage when blocking weak attacks (less than damage).
===Mobs===
; General
*AI has been improved.
; Skeletons
*Now shoot less quickly on Easy and Normal difficulties.
===Non-mob entities===
; Minecarts with chest & minecarts with hopper
* The GUI name is now the same as the item's display name.
===Command format===
; Selectors
* Entity selector c (count) now sorts on proximity using true coordinates, not coordinates snapped to the grid. – Selector c= targeting inaccurate entity position
===Gameplay===
; Combat
* Attack cooldown indicator is now enabled by default.Players who already played previous 1.9 versions may still need to manually enable the crosshair option (or delete options.txt to reset the default values).
=== General ===
; Loot tables
