With 26.4 Snapshot 4, we're breaking out a cool new block, introducing Brittle Ice! And Jukeboxes can now keep the music going with playlists by putting your music discs in a chest above them, making dance parties much easier. Just be careful not to dance on the Brittle Ice, as it'll start cracking under your feet...

Happy Dance Break!

New Features

• Added Jukebox Playlists
• Added Brittle Ice

Jukebox Playlists

• Place a single Chest, Trapped Chest, or any Copper Chest variant directly above a Jukebox to use its Music Discs as a playlist
• Discs play in slot order, skipping empty slots and other non-music-disc items and looping back to the start
• When a disc finishes, the Jukebox swaps it with the next disc in the chest
• If the chest has no Music Discs, the disc in the Jukebox plays again
• Ejecting the current disc skips to the next available disc

Brittle Ice

• Brittle Ice is a new block that can be found in Ice Caves
• Once a player or mob steps on it, it will start to crack and eventually break
• The Frostbite mob can walk on Brittle Ice without breaking it
• Brittle Ice only generates naturally in Ice Caves as part of the crevasse feature
• It is obtainable with Silk Touch
• It can also be created by water flowing onto a Blue Ice block
  • Any water block that borders the Blue Ice block horizontally will turn into Brittle Ice
