Minecraft Beta - 1.18.20.21 (Xbox / Windows / Android)

  • A world with "StorageVersion" 8 or lower will be increased to 9 and have its "RandomSeed" upgraded from using only the lower 32 bits of a 64-bit number to using the full 64-bit range while still representing the same number. This is only relevant for negative 32-bit seeds, which need a sign bit extension

**Additional Modding Capabilities Experiment/JavaScript APIs​

**

Important! In this release and starting with this beta, we are removing the Additional Modding Capabilities experiment.  This experiment contained experimental JavaScript APIs launched in 2018 – and with this removal, JavaScript within worlds associated with this API will no longer function.  GameTest Framework – a separate JavaScript API – should not be impacted, nor should behavior pack/resource pack type add-ons more broadly. You can read more about this via this article.​

 Commands​

  • Added '/tickingarea' command preload overload
  • Entities must now be loaded for an area to be considered fully loaded and ticking

Molang​

  • Molang expressions inside animation scripts for actor resource definition (pre_animation and initialize) that contain capital letters are properly evaluated now with format_version 1.18.20 or higher

User Interface​

  • The loading progress screen now shows when loading ticking areas marked for preload

Experimental Features

Commands​

  • Added a new '/volumearea ' command to create, remove, and list volumes in the world
