Java Edition 1.9.1

1.9.1 was an update for Minecraft, which was released on March 30, 2016. 1.9.1 is not compatible with 1.9 servers. Due to a catastrophic multiplayer bug it was replaced with 1.9.2 same-day.

Additions

 * Added elytra sound effects.
 * Sound event
 * Armor attribute
 * Damage formula is now, i.e. 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.

Changes

 * Attack indicator (Crosshair) is now enabled by default.
 * Session ID is now no longer printed by the game to the log files or to the launcher.
 * Entity selector  (count) now sorts on proximity using true coordinates, not coordinates snapped to the grid.
 * Loot tables now also work in dispensers and droppers.
 * Dispensers with arrows in jungle temples now use loot tables.
 * Hoppers can now push and pull items to and from blocked chests.
 * Increased limit per tick for scheduled tile ticks from 1,000 to 65,536.
 * Improved AI.
 * Shields no longer take damage when blocking weak attacks (less than damage).
 * The title of the inventory of Minecarts with Chests and Minecarts with Hoppers now match the item's name.
 * Skeletons shoot less quickly on Easy and Normal difficulty.

Fixes

 * Other fixes:
 * Fixed game engine adding non-existent entities (failed mob spawns, etc.) to its internal lists, increasing instability.
