rd-20090515 is a version of Pre-classic released on May 14, 2009.[1][note 1] This version is not available in the launcher; attempting to play it downloads rd-161348 instead.
Unlike other pre-classic versions, this does not use a "ddhhmm" (day-hour-minute) format, but instead a "yyyymmdd" (year-month-day) format.
Renamed "Cave Game" to "Minecraft: Order of the Stone".[2]
This version was once removed due to being identical to rd-161348, but later re-added to the launcher. Instead, the launcher now has two identical versions of Pre-classic.[3]
This is the only version in pre-classic with natural generation.
Changes
Level generation is now more natural.
Notes
↑While the version name implies that it was released on May 15, it was actually released at 10 pm UTC on May 14 (which is midnight on May 15, Sweden time).
↑Quote from PisuCat»
I'm saying it's identical to rd-161348. From searching around this version was added on the launcher on the 6th of August 2013, then removed (possibly renamed to rd-161348), and it has now been recently re-added under the old name rd-20090515.
Edit : It has been renamed you will find this version as rd-161348.
