Java Edition pre-Classic rd-20090515

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

Changes

 * Level generation is now more natural.

Trivia

 * 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.
 * 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.
