Splash text
New "missing texture" texture
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
Splash screens
"HURNERJSGER?"
"What's up Doc?"

Support for Java 5 and PowerPC users will be dropped[6][7]
If you have a PowerPC based computer and/or Java 5 installed, a warning will be shown at the main menu.
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
Launcher
Increases performance and stability
Minecraft game icon changed to a crafting table, presumably to differentiate between game and launcher
Allows LWJGL to be updated, fixing many launcher bugs

Self updatable.[8]
New password storing system [9]
More user friendly.[10]
A major step towards the Plugin API.[10]
New authentication system - "Yggdrasil", which is more secure and has more features
