1.15 Pre-release 1 (known as 1.15-pre1 in the launcher) is the first pre-release for Java Edition 1.15, released on November 21, 2019,[1] which optimized some aspects of the game, upgrades the resource pack version and fixes bugs.



Honey blocks



Dark prismarine
  • Increased scaffolding burn time when used as fuel in a furnace to be able to smelt 2 items, rather than 0.25.


Spawn eggs
  • Zombie pigmen spawn eggs can now be used on adult zombie pigmen to spawn baby variants.


Resource packs
  • The resource pack version is now 5 (due to texture mechanic changes in earlier snapshots).
  • The game now tries to make out of date resource packs work as much as possible.[more information needed]
    • The game can convert some of version 4 resource packs' outdated texture mechanics to the new mechanics.
  • Changed appearance of highlighted buttons used in menu screen and similar UIs.
    • Highlighted buttons now have a white outline.
    • Highlighted buttons no longer have a blue tint on them. Instead, they are now only slightly brighter than unhighlighted buttons.
