Java Edition 1.2.4

1.2.4 added new wood planks and sandstone blocks. It also improved chat editing.

Blocks

 * Wood planks
 * Now have the color of the type of wood used in crafting
 * Comes in all 4 types:
 * Oak wood planks
 * Birch wood planks
 * Spruce wood planks
 * Jungle wood planks
 * New sandstone block
 * Uses unused sandstone texture; however the texture is changed
 * Same name as the normal sandstone

Blocks

 * Wool
 * Slightly removed saturation out of every color

Mobs

 * Cats
 * When in standing position, cats will now purposely go and sit on nearby chests, active furnaces, and beds
 * This prevents players from using them

Gameplay

 * and keys can also be used
 * Up/down keys for recently sent messages
 * If you start typing a player's name, and press, it'll automatically type the rest of the username for you.
 * Copy & paste in chat
 * Similarly how in chat displays random characters,, ,  and  creates bold, striked, underlined and italic text respectively, whilst  resets any set states
 * These cannot be typed using vanilla clients
 * Pressing acts as a command key: it opens the chat with a “/” in place
 * Pressing or  will move the insertion point (text pointer) in the respective direction, allowing you to edit text instead of using  to go back
