Minecraft Snapshot 22w19a

Thursday snapshot! Apart from some bugfixes and some changes to fancy tags and commands, we're introducing "chat preview" as a way to cryptographically sign chat messages that have been dynamically styled by servers. And for this snapshot only, we've left in our testing option test-rainbow-chat in server.properties, which can be set to true together with the new previews-chat option for testing. If this is something that interests you, and especially if you run a server, we would love your feedback on it.

Enjoy!

Changes in 22w19a#

• Warden and Iron Golems now make sure to spawn above something solid

Technical Changes in 22w19a#

• Servers can now enable Chat Preview, which displays a server-controlled preview above the chat edit box
• Changes to the locate and place commands
• Point of Interest tags

Chat Preview#

• Servers can enable Chat Preview by setting previews-chat=true in server.properties
• When enabled, a server-controlled preview appears above the chat edit box, showing how the message will look when sent
• This can be used by servers to preview messages with styling applied, such as emojis or chat coloring
• Chat Preview sends chat messages to the server as they are typed, even before they're sent
  • The server then sends back the styled preview in real time
  • This allows servers to apply dynamic message stylings while still allowing chat to be securely signed
• A warning screen is shown on the client when joining a server with Chat Preview, and it can be globally disabled in Chat Settings
• Dynamic chat styling can also be controlled by the server, although this is only signed when Chat Preview is enabled
  • Clients can prefer to always show the original, signed message by enabling "Only Show Signed Chat" in Chat Settings

Commands#

• Added template sub-command to place-command
• locate command moved to locate structure, locatebiome moved to locate biome
• Added locate poi <type: point_of_interest_type>
• Servers will now also send an additional icon and MOTD packet after a player has connected
  • This allows servers with enable-status=false to set an icon and MOTD for players that successfully connect

Place template#

The place-command can now also place templates at a given location. Syntax: place template <template> [pos] [rotation] [mirror] [integrity] [seed]

• place template works like using the load button in the UI for a structure block

Parameters:

• template: The namespaced id of a template ("structure block file") to load and place
• rotation: The rotation to apply (if omitted, none is used)
• mirror: The mirroring to apply (if omitted, none is used)
• integrity: The structure integrity value between 0 and 1
• seed: The seed to use for the randomized degradation when integrity is less than 1

Point of Interest types#

• Removed unemployed and nitwit point_of_interest_types
• Added tag point_of_interest_type/acquirable_job_site for all job sites seeked by Villagers with none profession
• Added tag point_of_interest_type/village for PoI that are part of Village
