Minecraft Snapshot Update Released

Mojang has released a new Snapshot for Minecraft: Java Edition, introducing various new features, technical changes, and bug fixes. This update focuses on enhancing the visual and auditory experience of baby mobs, improving game performance, and refining core mechanics.

Key Features and Gameplay Changes

  • Craftable Name Tags: Name Tags can now be crafted using 1 Paper and 1 Metal Nugget (Copper, Iron, or Gold).
  • Baby Mob Visuals and Sounds:
    • Updated models and textures have been implemented for baby Cows, Sheep, Pigs, Cats, Ocelots, Mooshrooms, Wolves, and Chickens.
    • Baby Rabbits, both adult and baby, received new animations and bounding box adjustments.
    • New sound events have been added for baby Wolves, Cats, and Pigs.
  • Mob Behavior Adjustments:
    • Zombie Horses no longer panic when injured.
    • Armor on baby Wolves and saddles on baby Pigs will no longer render visually.

Performance Enhancements

Default JVM options have been tweaked to improve game stability and performance:

  • Increased RAM Allocation: The game now allocates 4 GB of RAM by default, an increase from the previous 2 GB.
  • Garbage Collector Change: The garbage collection system has been switched from G1GC to ZGC for compatible devices.
    • This change is intended to provide a smoother gameplay experience, reduce stutters, and offer a more stable framerate, particularly during memory-intensive tasks. Users with less than 4GB RAM or those wishing to modify the garbage collector are advised to consult relevant help articles. Third-party launchers may not support these modifications.

Technical Updates

  • Data Pack Version: Updated to 96.
    • Wolf sound variants have been restructured, moving into an adult_sounds field and adding a baby_sounds field.
    • New entity data fields (current_explosion_impact_pos and current_impulse_context_reset_grace_time) have been added to all mobs and the Armor Stand. The ignore_fall_damage_from_current_explosion field has been removed from Players.
    • A new item tag, #metal_nuggets, has been introduced, encompassing Copper, Iron, and Gold Nuggets.
  • Resource Pack Version: Updated to 77.
    • Numerous new entity textures have been added for various baby mobs, including different breeds of cats, chickens, cows, mooshrooms, pigs, rabbits, sheep, and wolves.
    • Existing entity textures have been renamed and moved to new directory structures for better organization.

Several issues identified in Snapshot 2 have been resolved, including:

  • Zombie horses burning to death due to constant movement in and out of water (MC-302734).
  • Visual gaps on zombie nautilus heads (MC-304361).
