General

 * Attribute system
 * Started to move over various things to a new attribute system:
 * Item attributes using NBT tags:
 * Attributes can be additive, subtractive and multiplicative using a set value.
 * Some items have default modifiers in place of previously hard-coded attributes.
 * Examples of possible changes players could make: A bow that slows the holder, a helm that buffs health, etc.
 * Entity attributes:
 * These properties can now be changed as easily as any other NBT attribute.
 * Entity speed, base health, base attack.
 * Other properties like weapon damage/bow draw speed/sword swing speed are yet to follow.


 * Internal chat system
 * Lots of messages should be translated now that were not previously.
 * Messages are now better modularized.
 * Server messages can be sent by their code-defined name, allowing the client to utilize the correct translation according to their language settings.
 * Color can be specifically designated, preventing leakage into further messages.

Items

 * Horse armor
 * No longer stackable.

General

 * Resource packs
 * Lots of work towards a new Resource Pack system, but not finished yet.
