azalea/CHANGELOG.md

Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog. Due to the complexity of Azalea and the fact that almost every Minecraft version is breaking anyways, semantic versioning is not followed.

[Unreleased]

Added

• HitResult now contains the entity that's being looked at.
• A QueuedServerBlockUpdates component that keeps track of block updates per Update.
• Local clients now have a TicksConnected component. (@Kumpelinus)

Changed

• Update to Minecraft 1.21.8.
• Renamed azalea_entity::EntityKind to EntityKindComponent to disambiguate with azalea_registry::EntityKind.
• Moved functions and types related to hit results from azalea::interact to azalea::interact::pick.
• Client::attack now takes Entity instead of MinecraftEntityId.

Fixed

• Fix packet order for loading (PlayerLoaded/MovePlayerPos) and sprinting (PlayerInput/PlayerCommand).
• Clients no longer send invalid look directions if the server teleports us with one.
• Movement code was updated with the changes from 1.21.5, so it no longer flags Grim.
• azalea-chat now correctly handles arrays of integers in the with field. (@qwqawawow)

[0.13.0+mc1.21.5] - 2025-06-15

Added

• This changelog. To see changes before this update, look at the git commits.
• azalea and azalea-client now have a packet-event feature, which can be disabled for efficiency if you're not using Event::Packet.
• StartJoinServerEvent can now be used to join servers exclusively from the ECS without a Tokio runtime.
• Add FormattedText::to_html and FormattedText::to_custom_format. (@Kumpelinus)
• Non-standard legacy hex colors like §#ff0000 are now supported in azalea-chat.
• Chat signing.
• Add auto-reconnecting which is enabled by default.
• ClientBuilder and SwarmBuilder are now Send.
• Add Client::start_use_item.
• The pathfinder no longer avoids slabs, stairs, and dirt path blocks.
• The pathfinder now immediately recalculates if blocks are placed in its path.
• Bots that use custom pathfinder moves can now keep arbitrary persistent state by using the CustomPathfinderState component and PathfinderCtx::custom_state.
• The reach distance for the pathfinder ReachBlockPosGoal is now configurable. (@x-osc)
• There is now a retry_on_no_path option in GotoEvent that can be set to false to make the pathfinder give up if no path could be found.
• azalea-brigadier now supports suggestions, command contexts, result consumers, and returning errors with ArgumentBuilder::executes_result.
• Proper support for getting biomes at coordinates.
• Add a new Client::entities_by which sorts entities that match a criteria by their distance to the client.
• New client event Event::ReceiveChunk.
• Several new functions for interacting with inventories (Client::get_inventory, get_held_item, ContainerHandleRef::left_click, shift_click, right_click, slots).
• Add Client::mine_with_auto_tool.
• Add Client::set_selected_hotbar_slot and Client::selected_hotbar_slot.
• Add Client::attack_cooldown_remaining_ticks to complement has_attack_cooldown.
• Add BlockPos::length, distance_to, and center_bottom.

Changed

• Client::goto is now async and completes when the client reaches its destination. Client::start_goto should be used if the old behavior is desired.
• The BlockState::id field is now private, use .id() instead.
• Update to Bevy 0.16.
• Rename InstanceContainer::insert to get_or_insert.
• Replace BlockInteractEvent with the more general-purpose StartUseItemEvent.
• Replace wait_one_tick and wait_one_update with wait_ticks and wait_updates.
• Functions that took &Vec3 or &BlockPos as arguments now only take them as owned types.
• Rename azalea_block::Block to BlockTrait to disambiguate with azalea_registry::Block.
• GotoEvent is now non-enhaustive and should instead be constructed by calling its methods.

Fixed

• Clients now validate incoming packets using the correct MAXIMUM_UNCOMPRESSED_LENGTH value.
• Several protocol fixes, including for ClientboundSetPlayerTeam and a few data components.
• No more chunk errors when the client joins another world with the same name but different height.
• Update the InstanceName component correctly when we receive a respawn or second login packet.
• azalea-chat now handles legacy color codes correctly when parsing from NBT.
• Send the correct UUID to servers in ClientboundHello when we're joining in offline-mode.
• Block shapes and some properties were using data from 1.20.3-pre4 due to using an old data generator (Pixlyzer), which has now been replaced with the data generator from Pumpkin.
• When patching the path, don't replace the move we're currently executing.
• The correct sequence number is now sent when interacting with blocks.
• Mining is now generally more reliable and doesn't flag Grim.
• Ghost blocks are now handled correctly due to implementing ClientboundBlockChangedAck.
• Player eye height was wrong due to being calculated from height instead of being a special case (was 1.53, should've been 1.62).
• The player inventory is now correctly updated when we close a container.
• Inventory interactions are now predicted on the client-side again, and the remaining click operations were implemented.
• Client::open_container_at now waits up to 10 ticks for the block to exist if you try to click air.
• Wrong physics collision code resulted in HitResult sometimes containing the wrong coordinates and inside value.
• Fix the client being unresponsive for a few seconds after joining due to not sending ServerboundPlayerLoaded.
• Fix panic when a client received ClientboundAddEntity and ClientboundStartConfiguration at the same time.
• Fix panic due to ClientInformation being inserted too late.
• ClientboundTeleportEntity did not handle relative teleports correctly.
• Pathfinder now gets stuck in water less by automatically trying to jump if it's in water.
