Developer notes

General

Added a new field mIsClientBiomeUpdate in LevelChunkPacketPayload

Pre-existing vanilla chorus plant blocks modified to include the minecraft:connection_north, minecraft:connection_east, minecraft:connection_south, minecraft:connection_west, minecraft:connection_up, and minecraft:connection_down block states, changing their permutations and hashed runtime IDs
Pre-existing vanilla fire blocks modified to include the minecraft:connection_north, minecraft:connection_east, minecraft:connection_south, minecraft:connection_west, and minecraft:connection_up block states, changing their permutations and hashed runtime IDs

Added new ActorType Frostbite.

Added IceBall ActorType

Added WhatGoesAroundComesAround to the MinecraftEventing::AchievementIds enum

Added HandSlot member Hand to ItemUseOnActorInventoryTransaction

Client-to-server login, skin, modal form response, NPC action, and identity assertion JSON payloads with more than 64 nested objects or arrays are now rejected; wire formats are unchanged

Pre-existing vanilla redstone dust blocks modified to include the redstone_north, redstone_east, redstone_south, and redstone_west block states (none, side, up), changing their permutations and hashed runtime IDs

Added HandSlot member Hand to ItemReleaseInventoryTransaction

Added Hand id to AnimatePacket used by Player hand swing actions to determine which hand is animating.

Update serialization of some packets and JSON to accurately reflect optionality of specific fields

Added an optional serverHandle parameter to LevelEventGenericPacket when the event id is 1900 or 1901
- Is sent as an int64

StartGamePacket updated

Added the 'Editor Achievements Migrated' field to the serialized 'LevelSettings' payload

ClientboundPlayAudioContentPacket

Added ClientboundPlayAudioContentPacket to send signed audio playback content with server authored sound options.

PlayerListPacket

Added PlayFab Id to PlayerListEntry, alongside XBL XUID and Platform Chat Id

The connection request now carries a signed PrimaryPlayFabId claim naming the primary player the sub-client is joining under, and a sub-client login that does not match the primary on the connection it arrives on is rejected with the new SubClientLoginNotBound disconnect reason; the packet layout is unchanged

PieceType enum

Added a new PieceType

PlayerListPacketPayload

The generated schema for Entries now documents its default value of []

Increased CurrentBlendVersion

Sounds

Added new Sound Event for the Brittle Ice Block's cracking

ChatPacket

The signing fields on SignedChat (Key Id, Sender Id, Room Id, Message Id and Signature) no longer reject an empty value, so an unsigned message is a message a receiver drops on policy rather than a malformed packet that disconnects the connection it arrived on.
A client that cannot reach the Chat Service now sends the message unsigned, carrying only Sender Id and Scan Text, so a signing outage cannot silence chat. The receiver decides whether to show or discard it.

ChatPacket

Added ChatPacket (id 361), carrying player chat along with a signature from a Mojang service
The Signed Chat block (Key Id, Sender Id, Room Id, Message Id, Scan Text, Redacted Text, Signature) is covered by that signature and must be relayed unmodified, or receiving clients cannot validate it
The optional Formatting block (Name Prefix, Name Postfix, Message Prefix, Message Postfix) is not covered by the signature and may be set freely by the server to decorate the name and the message

Added StringAttributeData as an attribute value type for EnvironmentAttributeData

CommandOutputMessage Raw Message support

Added an optional Raw Message field to CommandOutputMessage (carried by CommandOutputPacket). This holds a rawtext JSON payload for Scripting Custom Command results that return a RawMessage so the receiving client can localize it.

Developer notes

General

Added an optional serverHandle parameter to LevelEventGenericPacket when the event id is 1900 or 1901
- Is sent as an int64

StartGamePacket updated

Added the 'Editor Achievements Migrated' field to the serialized 'LevelSettings' payload

ClientboundMatchmakingStatePacket

Added the Canceled, PlayerLeftParty, PlayerLeftServer, ServerShutdown, TimedOut, and RequeueAsParty matchmaking states
Added optional matchmaking state details with the triggering player name and a flag that identifies a local player trigger

SubClientLoginPacket

The connection request now carries a signed PrimaryPlayFabId claim naming the primary player the sub-client is joining under, and a sub-client login that does not match the primary on the connection it arrives on is rejected with the new SubClientLoginNotBound disconnect reason; the packet layout is unchanged

SetPassengerOfBlockPacket

Added the SetPassengerOfBlockPacket to tell the client to start or stop riding a block AB#1688663

Developer notes

StartGamePacket

Fixed an issue where LevelSetting's areEducationFeaturesEnabled value was not being serialized using the old serialization system.

ClientboundUpdateSoundDataPacket

Fixed the event payload binding. The sound event variant was bound once per alternative, which wrote the whole variant seven times per packet and produced eight top-level fields in the docs. It is now a single tagged variant field Event, discriminated by a new SoundDataEventType (uint8) Type tag, matching the pattern used by other variant packets.
