Java Edition 16w38a

This page covers a development version that has a major issue under certain conditions.

 

The dedicated server for this version has a security vulnerability in the Log4j library that could be used to perform a remote code execution exploit. It can be addressed by appending a certain JVM argument to the server startup command line.^[1]

Gamerules

• doWeatherCycle
  • Determines whether the weather changes.
  • Defaults to true.

• maxEntityCramming
  • Defaults to 24.
  • If one entity tries to push more than 24 other entities, it starts to suffocate. (Note that pushing entities like minecarts also count towards this, although minecarts don't suffocate, mobs or players who push one, do suffocate)
    • The death message is (playername) suffocated in a wall.
  • Setting to 0 disables the rule.
  • Affects mobs and players only.

Cobblestone Walls and Mossy Cobblestone Walls

• Are now in the "Decoration Blocks" tab in the Creative inventory rather than the "Building Blocks" tab.

Farmland

• Using pick block gives the player farmland itself instead of dirt.

Target selectors

• Invalid selectors (such as @e[Type=creeper] instead of @e[type=creeper], @e[asdf] or @e[foo=nonexistent]) now generate an error instead of being silently ignored.
• Removed implicit target selectors (such as @e[167,28,454]).

Chat

• Messages can now be 256 characters long instead of 100.

Fishing

• Ink sacs are now caught in stacks of 10 with a weight of 1, rather than in stacks of 1 with a weight of 10.

Sounds

• Walking underwater no longer produces a step sound for the block the player is walking on.^{[note 1]}

Potions

• Potions that have missing or invalid potion-effect tags now default to the uncraftable potion, which now has no glint, and is now magenta in color.
  • This also applies to lingering potions, splash potions and tipped arrows.
  • Due to the water bottle without tags being changed to uncraftable potion, the brewing icon is also changed to uncraftable potion in the Creative inventory.

Elytra

• Visible when equipped on skeletons, zombies and armor stands.

Guardians and Elder Guardians

• Their common drop of raw fish will now be cooked fish if they die while on fire.
  • Their rare drops from player kills, which match fishing loot and are sometimes fish, are unaffected.

Rabbits

• Their raw rabbit drop is now affected by the Looting enchantment.

Skeleton Horses and Zombie Horses

• Their bone and rotten flesh drops (respectively) now yield 0–2, and are now affected by Looting.
