1.20.3 Pre-Release 1 (known as 1.20.3-pre1 in the launcher) is the first pre-release for Java Edition 1.20.3, released on November 20, 2023,[1] which makes changes to world resource packs and fixes bugs.

Changes

Blocks

Grass

  • Renamed "Grass" to "Short Grass".
  • The ID has been changed from grass to short_grass.

General

Data pack

  • The data pack version is now 26.

Resource pack

  • The resource pack version is now 22.
  • Changes to downloaded/world resource pack handling.
    • Changes apply to world resource packs (resources.zip), Realms resource packs and resource packs controlled by dedicated servers.
  • UI download screen has been replaced with a toast.
  • World resource pack application starts together with chunk loading.
  • Downloaded packs are now stored in downloads directory (with different file organization than old server-resource-packs)
    • Files in this directory are no longer automatically cleaned (previously only up to 10 packs were kept).
    • Additionally, inside this directory there is also log file log.json that stores information about downloaded files for debug purposes.
  • Downloaded packs now have unique id (GUID/UUID) that can be used to differentiate them.
    • This value for dedicated server pack can be configured with the resource-pack-id option in server.properties.
    • If the value is missing, it is generated based on URL.
    • If hash of a pack is not set, this pack is redownloaded before every application.
    • Previously, if hash was missing, the latest downloaded version of a pack was applied.

General

  • Some additional options are added for 3rd-party servers software:
    • Client can now accept multiple server resource packs.
    • New packet was added to un-apply server resource packs.
    • Resource packs are no longer cleaned when entering configuration phase.

Experimental

These additions only take effect when the Update 1.21 experimental data pack is enabled.
