rd-20090515 is a pre-Classic version made on May 14, 2009, at 22:00 UTC.[1][note 1] Although there is a version titled "rd-20090515" in the launcher, attempting to play it downloads rd-161348 instead.


  • Level generation is now more natural.


  • Unlike other pre-classic versions, this does not use a "ddhhmm" (day-hour-minute) format, but instead a "yyyymmdd" (year-month-day) format.
  • The game is renamed from "Cave Game" to "Minecraft: Order of the Stone" in this version.[2]
  • This version was once removed from the launcher due to being identical to rd-161348, but later re-added, although it remained a duplicate of rd-161348.
  • The “rd” prefix in the update’s name stands for RubyDung, a previous game Notch worked on and abandoned, and was used as some of Minecraft’s inspiration.


  1. While the version name implies that it was released on May 15, it was actually released at 22:00 UTC on May 14 (which is midnight on May 15, Sweden time).
