==== NBT ====
No changes so far.
 
The NBT specification was changed so that the root tag is no longer required to be a [[NBT#Specification:compound_tag|Compound Tag]] when sent over the network.
 
Presently in the pre-release, only [[NBT#Specification:compound_tag|Compound Tag]] and [[NBT#Specification:string_tag|String Tag]] types are used as root, but the Notchian server/client implementation is able to handle [[NBT#Specification|NBT Tags]] of any type.
 
==== Chat ====
 
The [[Chat]] type is now serialized as a [[NBT#Specification|NBT Tag]] instead of a JSON String, unless explicitly stated otherwise.

| Encoded as a [[NBT|NBT Tag]], with the type of tag used depending on the case:
* As a [[NBT#Specification:string_tag|String Tag]]: For components only containing text (no styling, no events etc.).
* As a [[NBT#Specification:compound_tag|Compound Tag]]: Every other case.
