== Trivia ==<br />
* This version has the same protocol version number as [[Minecraft:25w41a]]. The two versions are not actually compatible; 1.21.9-rc1 throws a "Network Protocol Error" message when attempting to join a 25w41a world, and 25w41a crashes when attempting to join a 1.21.9-rc1 world.<br />
