Java Edition

Release date

Client (.json)



A version of Minecraft Infdev was released on March 25, 2010.[1][2]


  • Re-implemented caves.
  • Ores now generate in blobs.
  • Re-added many particles.
  • Re-implemented block ticks, allowing for crops to grow, fire to spread, grass to spread to dirt, and more.
    • You can no longer place fire on the sides of non-flammable blocks
    • Flowers pop off when not exposed to sunlight
    • Slabs will now make double slabs when possible.
  • Furnaces now work like they did before Infdev.


  • The game progressively degrades in performance, becoming unbearably slow within minutes of loading a world. (This is caused by flowers that are generated in places where they break as soon as they appear, resulting in an increase in the number of entities.)
  • Above-ground cave entrances cut into trees and brick pyramids, resulting in half-destroyed trees and brick pyramids containing caves. The entrances also do not turn dirt into grass, which results in patches of dirt strewn across the terrain near cave entrances.


  • Due to the removal of the duplicate login detection, the game no longer randomly crashes with the "session conflict" screen.
