1.9.3 is a minor update to Minecraft (Java Edition) released on May 10, 2016,[1] which adds the /stopsound command, limits the y-value of /tp, and improves Minecraft 's networking libraries. It is not compatible with 1.9.2 servers. However, due to an incorrect snapshot warning when loading a world saved in an older version, 1.9.3 was replaced by 1.9.4 the same day.

Additions[]

Commands[]

/stopsound
  • Permits the player to choose which specific sounds should be stopped from playing.
    • Syntax: /stopsound <targets> [<source>] <sound>.

Changes[]

Commands[]

/tp
  • No longer teleports the player to a y-coordinate outside the range −512 to 512.

General[]

Networking
  • As of the release of this version, the Netty networking library that Minecraft uses, now checks sessionserver.mojang.com/blockedservers when connecting to a multiplayer server, and if the server is on the blocked server list, it reports to the user that the server is unavailable.
    • The blocklist consists of servers in violation of the Minecraft EULA (End User License Agreement).
    • This affects all versions that depend on the Netty library, back to version 1.7.2 snapshot 13w41a.
  • Better memory use of pathfinding and biome caching.
    • This prevents memory leaking.
