Release Java Edition Bug-fix update Patch of 1.9 Combat Update

Minecraft 1.9.1

Released on 30 March 2016, Minecraft Java Edition 1.9.1 is the first bug-fix update for 1.9, the Combat Update. It adds Elytra sounds, makes the attack cooldown less confusing and fixes a piston bug that duplicated blocks. Connection errors on Realms led Mojang to replace it with 1.9.2 the same day.

Key takeaways

  • Fixes: block duplication with Pistons (MC-96219), a world border damage bug (MC-56162) and transparency issues on the Elytra texture (MC-98327).
  • Tweaks: Elytra sound effects, improved mob AI and entity selectors, and attack cooldown mechanics that are less confusing.
  • Short-lived: 1.9.2 replaced it the same day because 1.9.1 caused connection errors on Realms (MC-100283).
