• Fixed MCStats support.
• Added WDL Packet #2, which isn't used by the currently released versions of WDL but will be in the next release (1.8c). This packet contains the server's entity track ranges, which are needed by WDL to determine when an entity is despawned (only available on spigot servers, of course). (If this isn't sent, vanilla minecraft's ranges are used, although the player can configure the proper ones; you can disable this packet with the config key wdl.sendEntityRanges).
• Warnings when configuration keys are missing
• Per-world configuration: see the example config. If a value isn't set per-world, the default value is used.

• If running a non-spigot server, error messages about "Ex in entityranges" will be displayed. These can safely be ignored; it'll be disabled in the next version. If you want to disable them now, you can simply create spigot.yml in the server's base directory, with the following as contents:

  world-settings:
    default:
      entity-activation-range:
        players: 48
        animals: 48
        monsters: 48
        misc: 32
        other: 64
