[MC News] Minecraft 26.3 Snapshot 4

[xSicKxBot]

Happy Snapshot Tues... Thursday? Yes, you read that right! As we've entered peak vacation season here in Sweden, snapshots might not come out on their usual schedule.

In today's snapshot we have switched the library used for window management, input and platform integration from GLFW to SDL3.

We have also added new item components for custom furnace fuels, as well as several technical changes for signs, world generation and loot tables.

Happy mining!

Known Issues

• Exclusive fullscreen mode on Windows may cause the game to crash in certain situations, especially when using multiple monitors
  
• Entering Exclusive fullscreen mode crashes the game on Wayland
  

New Features

• Players in spectator mode can now interact with portals to teleport
  

Changes

Minor Tweaks to Blocks, Items and Entities

• Armadillos no longer try to roll up when submerged in liquids
  

UI

• Removed the Raw Input mouse settingMouse input now always uses relative mouse mode while playing in-game
  
• Key bindings now use physical keys instead of keyboard-layout-specific key codes
  
• Borderless Fullscreen is now the default fullscreen mode
  
• Switching between Borderless and Exclusive Fullscreen no longer requires restarting the game

Debug Overlay

• The debug overlay now supports a separate GUI scale than the rest of the gameThis is customizable through the Debug Options screen, F3 + F6The default scale is "Auto", which tries to stay at a higher resolution than normalAnother option is "Unchanged", which matches your regular GUI scaleThe rest of the options work the same as in the normal "GUI Scale", controlling the scale directly
  
• Added a "player_speed" debug entry that displays the speed of the player in blocks per tick.
  
• The debug overlay now shows the display refresh rate
  

Creative Inventory

• Reordered mineral item and block ordering to have non-tiered ingredients up first, then tiered ingredients that craft into equipment lastIngredientsNon-tiered mineralsUnrefined tiered mineralsRefined tiered mineralsNuggetsIngotsBuilding BlocksNon-tiered mineral blocks and variantsRefined tiered mineral blocks and variantsCopper block familyCopper Blocks continue to be pushed to the end of the order in Building Blocks since they have a large list of content
  
• Improved ordering of Natural Blocks tab so that all inner ordering of group content sequentially progresses from Overworld -> Nether -> End to stay consistent with other tabs
  

Technical Changes

• The Data Pack version is now 111.0
  
• The Resource Pack version is now 92.0
