Minecraft 1.9.3 And 1.9.4

Minecraft versions 1.9.3 and 1.9.4 have been released yesterday.

Minecraft 1.9.3 Changelog

Additions

• New command: /stopsound
  • usage: /stopsound <player> [source] [sound]

Changes

Commands

• /tp will no longer teleport the player to a y-coordinate outside the range -512 to 512.

Networking

• As of the release of this version, the Netty networking library that Minecraft uses now checks https://sessionserver.mojang.com/blockedservers when connecting to a multiplayer server, and if the server is on the blocked server list, 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.
• Realms and AI tweaks.
• Better memory use of pathfinding and biome caching.
