Changes

 * Commands

 * 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.
