Minecraft Snapshot 23w40a

We are now releasing Snapshot 23w40a, the first snapshot for 1.20.3! This snapshot contains improvements for shields, changes to chat component serialization and bug fixes.

Changes

When a player is blocking with a shield, the arm with the shield now follows the direction the player is looking at, when viewed from third person perspective

Technical Changes

The Data Pack version is now 19
A few minor changes to chat component serialization

Serialization

Plain-text chat components are now always serialized as string instead of {"text': "blah"}
Chat components now serialize to NBT when sent over network
Chat components now have an optional type value to speed up parsing and improve error checking
id field in show_entity hoverEvent style now also accepts UUID as an array of 4 ints
Numeric and boolean arguments for translate component are no longer converted to string
Errors in the following style fields are no longer silently ignored: color, clickEvent, hoverEvent, and more
