Minecraft Snapshot 26.3w4: SDL3 Engine Switch & Technical Overhaul

Major Engine & Feature Updates

Minecraft is making a massive leap by migrating from GLFW to SDL3 for input and window management, aimed at better platform performance. Spectator mode just got a major quality-of-life boost, allowing direct portal interaction to teleport through dimensions.

Detailed Tweaks & Features

  • Input Handling: The game now uses SDL scancodes for more consistent key binding support.
  • Debug Overlay: You can now customize GUI scales independently for the debug screen via F3+F6.
  • Inventory Cleanup: The Creative menu received a cleaner organization for minerals and natural blocks.

Everything else is dozens of bug fixes and technical polish. A heavy backend update that paves the way for better stability.
