Additions

Blocks

[edit | edit source]

Red sand

  • Generated on the lowest surface levels of the mesa biome.
  • Behaves like normal sand.
  • Can be smelted into glass and crafted into TNT, but cannot be crafted into sandstone.

Non-mob entities

[edit | edit source]

Minecart with command block

  • Can only be obtained using /give @p 422, /give @p hopper_command_block or /summon MinecartCommandBlock.
  • Activated by activator rails.
    • Run their command every so often as long as they are powered - a command block minecart going across a single powered activator rail at full speed runs its command thrice.
  • Can be success-tested while on a detector rail with a redstone comparator next to the rail (just like how the minecart with chest and minecart with hopper can be fill-checked).

Changes

Items

[edit | edit source]

Enchanted books

  • Can now give multiple enchantments.

World generation

[edit | edit source]

Badlands

  • Orange terracotta generates in place of sandstone, but not in the same type of formation.

General

[edit | edit source]

Logging

  • Now done using Log4j 2.
    • Default logging location is now in logs/latest.log, older logs are archived in logs/year-months-day-counter.log.gz with GZIP compress. The year is 4 digits, and the month and day are both 2 digits. The counter is the number of startups on the day. The counter is 1 when the first startup of the day and increasing each startup.
    • The way logs are saved can be changed, examples: HTML page, database, errors only, no logging at all.
    • As a result, this is the first version to be affected by the Log4Shell security vulnerability, although running the game through the current launcher will automatically apply a patch to fix it.
