rd-132211 is the first labeled pre-Classic version of Minecraft, created on May 13, 2009, at 20:11 UTC.^[1] It is the earliest version available through the Minecraft Launcher and the oldest archived version of Minecraft.

The copy in the launcher was last modified on August 6, 2013, making it technically not original.

Controls

• Placing and destroying blocks.
  • Left-click places a block. Right-click destroys a block.
  • Blocks cannot be placed beyond the world border.
  • The build limit is Y=64.
  • Players can place blocks within the space they occupy.
  • Added a flashing white overlay highlighting the face of the targeted block when hovering with the mouse.
• The level is saved when ⏎ Return is pressed or when the game is exited.

General

• Level generation was redesigned from the irregular terrain shown in Cave game tech test to produce a completely flat world, similar to a modern superflat world.
• Terrain generates from Y=0 to Y=43.
• Space below Y=0 is empty.
• The top layer at Y=43 consists of grass blocks, while all lower terrain consists of stone.

Caves

• No longer generate.

3 bugs reported

• Blocks can be placed directly within the space occupied by the player.^[2] This bug remained in the game until Classic 0.0.9a.
• On some systems, commonly those using Intel GPUs, severe lag may occur when approaching the ground after starting the game, reducing performance to approximately 1 FPS. Building upward by at least three blocks may alleviate the issue on some systems.^{[note 1]}
• The camera pivot bug causes the view to rotate around a fixed point in the world instead of rotating on the player's axis. This causes the player's perspective to shift as the camera rotates.

• The "rd" prefix in the version title stands for RubyDung, a game Notch was developing in early 2009 whose codebase was repurposed for Minecraft.
• Level data is saved in a single level.dat file inside the game's root directory, unlike future versions that have dedicated folders.
• Although the intended world size is 256×64×256, worlds of any dimensions can be loaded. Worlds smaller than the intended size have terrain generated over them, while larger worlds are truncated.
• Grass blocks are stored using the same block ID as stone; the difference between them is purely visual.
• Despite normally only using 2 block IDs (0 and 1), 0–255 are all possible IDs. Invalid IDs appear as air, but do not get converted into it upon saving the world.
• Because of these behaviors, nearly any gzipped file named level.dat can theoretically be loaded as a world, including a modern level.dat file. Saving such a world is likely to corrupt it because of terrain generation or truncation.
