  - target is already riding a vehicle;
  - target and vehicle are the same entity;

General

Protocol

Added a network protocol feature for forcing bundle of packets to be processed within same client tick.
- Added new delimiter packet to clientbound game protocol.
- All packets between two delimiters are guaranteed to be processed within same tick.
- For security reasons this feature is not supported in serverbound direction.

Changes

Changed their textures.

Vexes

Now use a separate charging animation when empty-handed.

Non-mob entities

Armor stand

Now preserve custom names when placed and broken.

Minecart with hopper

No longer have TransferCooldown data.

Command format

Chat component

Added an optional fallback field to translate text components.
- The new field is a string that is used in place of translation if it is missing.
- If fallback is missing, the old behavior (i.e. using the key itself as the translation) is preserved.
Out-of-bound arguments in translate formats are no longer silently ignored.

/clone

Now supports specifying the source and target dimensions, new syntax:
- /clone [from <sourceDimension>] <begin> <end> [to <targetDimension>] <destination> ...
  - sourceDimension: ID of dimension to clone from.
  - targetDimension: ID of dimension to clone to.

/data

New source string available, to read a value as text and resulting in a string value, syntax:
- ... (insert <index>|prepend|append|set|merge) string (block <sourcePos>|entity <source>|storage <source>) [<sourcePath>] [<start>] [<end>]
  - start: index of first character to include at the start of the string.
  - end: index of the first character to exclude at the end of the string.

/execute

On (if|unless), new conditions available:
- ... loaded <pos>: checks if the position given is fully loaded (in regard to both blocks and entities).
  - pos: block position to check.
- ... dimension <dimension>: checks if the execution is in a matching dimension.
  - dimension: a dimension ID.
New sub-command: on, for selecting entities based on relation to the current executing entity, syntax:
- ... on (attacker|controller|leasher|owner|passengers|target|vehicle) -> execute
  - attacker: last entity that damaged the executing entity in the previous 5 seconds.
  - controller: entity that is controlling the executing entity (for example: first passenger in a boat).
  - leasher: entity leading the executing entity with a leash (might be a leash knot in case of being attached to a fence).
  - owner: owner of the executing entity, if it is a tameable animal (like cats, wolves or parrots).
  - passengers: all entities directly riding the executing entity (no sub-passengers).
  - target: attack target for the executing entity.
  - vehicle: entity that the executing entity is riding.
- If the relation is not applicable to the executing entity or there are no entities matching it, selector returns zero elements.

/title

All time arguments to /title times are now time durations and work with t, s, and d suffixes.

/weather

The duration of the weather change now matches the game's regular weather cycle if not specified.
The duration parameter is now a time duration in ticks and works with t, s, and d suffixes.
- To retain existing functionality, you need to add an s suffix to pre-existing commands.
