Minecraft Snapshot 20w30a

Today we're releasing Snapshot 20w30a for Minecraft Java Edition in which we've tweaked Bastion Remnants, and given you the ability to have lanterns under water.

Changes in 20w30a

• Modified how respawn positions are chosen for beds and respawn anchors
• Lanterns can now be waterlogged
• Soul Lanterns can now be waterlogged
• Tweaked the Bastion Remnant chest loot
• Chests in Bastion Remnants are now more likely to be located on top of gilded blackstone

Respawn Block Positions

• Respawn anchors will prioritize cardinal directions over corners
• Beds will prioritize the side of the bed the player entered from and then spaces circling around the foot of the bed up to the head of the bed
• Respawning players will now face the block that they respawned at
• Placing players onto dangerous blocks is now avoided when possible

Technical Changes in 20w30a

• The sign edit screen will now intialize from existing sign text (should have no noticeable impact on vanilla)
• Tags can now have optional entries

Optional Tag Entries

Entries in tags can now be marked as optional. Failure to resolve optional entries does not prevent the whole tag from loading.

Example:

{
  "replace": false,
  "values": [
    "#minecraft:beds", // existing syntax
    { "id":"#missing:tag", "required": false }, // optional sub-tag entry
"minecraft:anvil", // existing syntax
{ "id":"minecraft:stone_button", "required": true }, // new syntax for required tags
{ "id":"missing:block", "required": false } // optional single-element entry

]
}
