Minecraft 1.21.6 Pre-Release 1 – Vibration Upgrades and UI Dialog Overhaul

Minecraft 1.21.6 Pre-Release 1 introduces targeted bug fixes and technical enhancements in preparation for the summer “Chase the Skies” release. Highlights include a refined vibration system for equipment interactions, adjusted ambient audio settings, and a massive overhaul to in-game dialog mechanics. Players and mapmakers alike will benefit from these UI-focused improvements, while survival users gain more immersive mob behavior corrections and sound refinements.

Features:

• Dried Ghast & Vibration Tuning
  • The Dried Ghast now emits vibration frequency 11 when its block state changes (e.g. being broken or triggered).
  • Removing saddles, horse armor, or llama carpets triggers:
    • Frequency 6 if removed with shears.
    • Frequency 4 if removed without shears.
  • Ambient sound for Dried Ghast is now managed under the “Blocks” audio category, no longer “Environment.”
• Happy Ghast Collision Fix
  • Players riding a Happy Ghast can no longer pass through another player’s Happy Ghast resolving key multiplayer desync issues.

Technical Improvements:

• Data Pack Version 79
  • Dialog behavior has been restructured for more precise control and compatibility.
  • Developers can now:
    • Control whether dialog pauses the game or auto-closes.
    • Accept player input (text, boolean, numerical).
    • Use the new after_action field to define what happens after player input.
    • Use better-defined output formats (plain text or NBT).
    • Display a response-waiting screen on slow connections.
• Quick Actions (G key)
  • New shortcut system for servers/custom maps.
  • Pressing G triggers pre-defined dialogs via the minecraft:quick_actions tag:
    • If empty, nothing happens.
    • If one dialog is defined, it opens directly.
    • If multiple dialogs exist, a menu is shown.
  • Extremely useful for custom servers, minigames, or command-based interactions.
• Resource Pack Version 63
  • oversized_in_gui: Boolean flag for letting items overflow GUI slots (useful for exaggerated visuals).
  • minecraft:player_head: Allows proper rendering of custom player heads from skins improves profile compatibility.

Fixes:

• Mob & Equipment Bugs:
  • MC-297275: Fixed desync when jumping while mounted on Happy Ghast.
  • MC-297550: Happy Ghasts now stay in place when players dismount correctly.
  • MC-297868, MC-297893, MC-297894: Items in saddle/armor.body slots now behave correctly on death, with enchantments, and when using /clear.
• Dialog & UI Issues:
  • MC-297807, MC-297848: Exiting dialogs now properly transitions screens.
  • MC-297915: Empty custom nameplates render correctly.
  • MC-298071: Zombie villagers now correctly spawn with professions again.
  • MC-298116, MC-298117: Improved button states and visibility in Realms and link confirmation dialogs.
• Performance & Graphics:
  • MC-297899: Fixed cloud-related FPS drops.
  • MC-298139, MC-298146: GUI overflow and disappearing item visuals fixed at high resolutions.
• Command & Technical Bugs:
  • MC-296420: /datapack create no longer creates folders with illegal names.
  • MC-297906: Large command output no longer causes silent disconnects on servers.
  • MC-296458: Player heads now render with the correct appearance.
