Java Edition 22w19a

22w19a is the tenth and final snapshot for Java Edition 1.19, released on May 12, 2022,^[1] which introduces chat preview, merges /locate and /locatebiome into the new /locate, adds the ability to locate a POI (Point of Interest), the ability to place a template, and fixes bugs.

/locate

• Added /locate poi, can locate a POI (Point of Interest), with following syntax:
  • /locate poi <poi>
    • poi: The namespaced ID of a POI, or a POI tag.

/place

• Added /place template, can place templates at a given location, with following syntax:
  • /place template <template> [<pos>] [<rotation>] [<mirror>] [<integrity>] [<seed>]
    • Works like using the load button in the UI for a structure block.
    • template: The namespaced ID of a template ("structure block file") to load and place.
    • pos: The position to use as the origin for the generation. (if omitted, ~ ~ ~ is used)
    • 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.

Chat

• Servers can now enable chat preview, which displays a server-controlled preview above the chat edit box, showing how the message appears when sent.
  • 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 toast message 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.

Options

• Added "Chat Preview" chat option, for enabling chat preview. Toggled on by default.
• Added "Only Show Signed Chat" chat option, for clients who prefers to always show the original, signed message. Toggled off by default.

options.txt

• Added chatPreview and onlyShowSignedChat.

Protocol

• Servers 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.

server.properties

• Added server property previews-chat to enable chat preview.
  • Defaults to false.
• Added temporary server property test-rainbow-chat, for this snapshot only.

Tags

• Added following point_of_interest_type tags (new type):
  • #acquirable_job_site: armorer, butcher, cartographer, cleric, farmer, fisherman, fletcher, leatherworker, librarian, mason, shepherd, toolsmith, and weaponsmith.
    • This tag defines job sites sought by villagers with none profession.
  • #bee_home: beehive and bee_nest.
    • This tag defines POIs that bees target.
  • #village: #acquirable_job_site, home, and meeting.
    • This tag defines POIs that belongs to villages.

Iron golem

• Now make sure to spawn above something solid, so they can now spawn on top of glass and leaves and are no longer blocked by things like string.

Tadpole

• Hitbox is now reduced from 0.5×0.4 to 0.4×0.3.

Warden

• Now make sure to spawn above something solid, so they can now spawn on top of glass and leaves and are no longer blocked by things like string.
• Ranged attack damage is now affected by difficulty.

Mineshafts

• No longer intersect with ancient cities.

/locate and /locatebiome

• Merged into the new /locate command:
