1.9.1-pre1 is the first pre-release for 1.9.1.[1][2]

Additions[edit | edit source]

Elytra
  • Added sound effects, while gliding in the Elytra.
    • Sound event item.elytra.flying
Armor
  • New armor attribute: generic.armorToughness
    • Damage formula is now damage = damage * ( 1 - max( defensePoints / 5, defensePoints - damage / ( 2 + toughness / 4 ) ) / 25 ), 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.
  • New option enableWeakAttacks in options.txt
    • Defaults to false. When false, the client will ignore attempts to attack when weapon cooldown is less than 75% recharged.
    • The effect was removed in the final release, however the option itself remains.

Changes[edit | edit source]

  • Session ID is now no longer printed by the game to the log files or to the launcher.[3]
  • Entity selector c (count) now sorts on proximity using true coordinates, not coordinates snapped to the grid.[4]
  • Missing an attack no longer triggers the weapon cooldown (later reverted in final release.)
  • Loot tables now also work in dispensers and droppers
  • Hoppers can now push and pull items to and from chests, that are blocked from opening.
  • Increased limit per tick for scheduled tile ticks from 1,000 to 65,536.
  • Improved AI.[Verify]

Fixes[edit | edit source]

7 issues fixed
From released versions before 1.9.1
  • MC-7961 – Hopper can't fill or empty a chest if the chest is blocked from opening.
  • MC-56162 – Setting /worldborder damage amount 0 doesn't work.
  • MC-95352 – Spatial target arguments c, dx, dy, dz behave unexpectedly and inconsistently.
From version 1.9
  • MC-90257 – A chain of command blocks may takes more than 1 tick to traverse.
  • MC-96219 – Block duplication bug with pistons (ghost blocks).
  • MC-96927 – Selector c Targeting Inaccurate Entity Position
  • MC-98327 – Elytra texture transparency issues.
Other fixes
  • Fixed game engine adding non-existent entities (failed mob spawns, etc.) to its internal lists, increasing instability.[5]
