1.20 Pre-release 1 (known as 1.20-pre1 in the launcher) is the first pre-release for Java Edition 1.20, released on May 10, 2023,[1] which brings more parity from Bedrock Edition and fixes bugs.

Changes[]

Blocks[]

Beds, Carpets, and Wool
  • Colored variants can now be dyed any other color.

Command format[]

/data
  • string data sources now accept negative boundaries, which are interpreted as index counted from the end of the string.

General[]

Damage type
  • Added outside_border, and generic_kill.
    • Players outside the world border are now hurt by the damage type outside_border instead of in_wall.
    • Forcibly removing an entity using i.e. the /kill command now uses damage type generic_kill instead of out_of_world.
Death messages
  • Changed death message used for the /kill command.
    • Changed from "<player> fell out of the world" to "<player> was killed".
  • Changed death message used for deaths caused by the world border.
    • Changed from "<player> suffocated in a wall" to "<player> left the confines of this world".
Loot table
  • Random sequences for loot tables are now deterministic.
    • The game now uses named random sequences to deterministically produce loot for loot tables.
    • Each random sequence produces a unique sequence based on the world seed and sequence identifier, which means a loot table will produce the same results when ran with the same parameters in the same world.
    • The identifier of the random sequence to use for a loot table is specified as a resource location in a new field called random_sequence.
server.properties
  • Changes in encoding.
    • The file is now read in UTF-8 initially, with previous encoding (ISO 8859-1/Latin 1) as a fallback.
    • File is now written with UTF-8 encoding.
Tags
  • Removed pumpkin, and melon from #maintains_farmland block tag.
  • Added generic_kill, and outside_border to #bypasses_armor damage type tag.
  • Added generic_kill to #bypasses_invulnerability, and #bypasses_resistance damage type tags.
