The redesigned pause menu

Minecraft:Pause menu

• The pause menu has been updated with a new layout and design.

Technical

AI Goals

• Made the schemas for the Template:Cd, Template:Cd, Template:Cd, and Template:Cd stricter when parsing and will fail to load an entity JSON that has invalid data in versions 1.21.120 and newer.

Minecraft:Blocks

• Custom blocks with textures in the Template:Cd array no longer require the Upcoming Creator Features Minecraft:experiment toggle to work properly.
• The parameter Template:Cd was removed from the Minecraft:water configuration JSON file, and consequently the file has a new format and was upgraded to version 1.21.120.

GDK

• Minecraft Preview for Windows now runs on the latest GDK (Game Development Kit).
  • This update aligns the game with the standard distribution model on Windows platforms.
• File paths have been updated and upon first install load of this version of Minecraft Preview, existing Minecraft worlds and content will shift to: Template:Cd.
• Some players will still receive the UWP version of Minecraft Preview as this slowly rolls out for testing.
