Java Edition 1.2.4

1.2.4 is a minor update to Java Edition released on March 22, 2012,^[1] which adds new planks and sandstone blocks, improves chat editing, and fixes some of the bugs and crashes in 1.2.3.

Birch wood planks

Spruce wood planks

Jungle wood planks

• All planks currently have the same tooltip: "Wooden Planks".

Sandstone variants

• Use a modified version of the unused sandstone texture from 1.2.1.
• Have the same name as the normal sandstone.

Glass

• Now drops itself when broken using a tool with Silk Touch.

Sandstone

• Texture changed from .

Wool

• Slightly desaturated every color, changing from to .

Cats

• When in a standing position, cats now purposely go and sit on nearby chests, active furnaces, and beds.
  • This prevents players from using them.

Pigs

• Saddles can no longer be put on baby pigs. Saddled baby pigs from previous versions can update to this version and still be ridden.

Chat

  • Links are now clickable in chat.
    • When clicked, a warning screen appears that asks players if they want to continue.

  • The chat edit box is no longer prefixed with a greater-than sign (>).
• When typing a player's name, pressing ↹ Tab automatically fills in the rest of the username.
  • Text can now be copied and pasted.
  • Similar to how the formatting code §k displays random characters in chat, §l, §m, §n and §o creates bold, striked, underlined and italic text respectively, while §r 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 ← Left or → Right moves the insertion point (text pointer) in the respective direction, allowing text to be modified.

Out of Memory screen

• Added "Back" and "Quit" buttons

Debug screen

  • The same as the regular F3 menu, except without the graph/profiler.
