Jukebox Playlists

A jukebox in playlist mode saves the chest slot it last took a disc from. Even if the discs are moved around, or the chest is broken and placed again, the jukebox will play the next disc starting from the saved slot.

Brittle Ice

Brittle Ice has 0.5 hardness, 0.5 blast resistance, and 0.98 friction (same as Packed Ice and Frosted Ice).

The best tool for Brittle Ice is a pickaxe. It breaks when pushed by a piston and cannot be pulled.

Brittle Ice shows up as #A0A0FF “Ice” on a map. When placed under a note block, they make the “Chime” instrument sound.

Players, mobs, armor stands, and mannequins crack Brittle Ice when stepping on it directly. Riding a vehicle such as a boat will not crack the ice.

Brittle Ice generates fully intact, cracks in three stages, then breaks completely. After each stage, the block schedules a tick 24 ticks in the future and will not crack until 24 ticks pass.

Once a Brittle Ice block breaks completely, neighboring Brittle Ice blocks crack by one stage. If a neighboring block breaks completely, it does not cause a chain reaction.

Brittle Ice formed by water horizontally bordering Blue Ice will not crack for 24 ticks.

Ice Caves

Ice Caves can now generate mineshafts.

Misc

Players can no longer click on portals in the Debug mode world to teleport to another dimension.
