Java Edition 1.2.4

1.2.4 was a minor update to Minecraft (Java Edition) released on March 22, 2012, which added new 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

 * New sandstone block
 * Uses unused sandstone texture; however the texture is changed
 * Same name as the normal sandstone

Blocks

 * Slightly removed saturation out of every color


 * Sandstone

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


 * Pigs
 * Baby pigs can no longer be ridden
 * Despite that, players are still able to place a saddle on them

Gameplay

 * Chat
 * Added chat history and much better chat editing
 * Links are now clickable in chat
 * When clicked, a warning screen appears that asks players if they want to continue
 * Players can copy and paste links in chat
 * Mouse wheel can be used to scroll up/down for history
 * 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


 * Out of Memory Screen
 * Added “Back” and “Quit” buttons


 * F3 debug screen

 * The same as the regular menu, except without the graph/profiler
 * Accessible by +
