Bukkit

v1.50 for MC 1.6.2, 1.7.x, 1.8.x

• Added support for craftbukkit/spigot 1.8.3.
• Experimental: Unlocked a bunch of remaining living entity types for use as shopkeeper objects: bat, blaze, cave_spider, spider, ender_dragon, wither, enderman, ghast, giant, horse, magma_cube, slime, pig_zombie, silverfish, squid (no MC 1.8 entities yet) Those are highly experimental! They are disabled by default in the configuration: you might need to remove the 'disabled-living-shops' section in your config in order to let it regenerate with the new default values.
  Some of those entities (currently: bat, ender_dragon, wither, enderman, silverfish) get the new NoAI entity tag set in order to prevent the biggest issues with them: As this new tag is only available on MC 1.8 you should only enabled those if you are running on MC 1.8.x.

Currently known issues with those new entity types (there might be more issues.. usage on own risk):

• chicken: Still lays eggs.
• bat: Without the NoAI tag it flies around. If NoAI tag is available (MC 1.8) the bat is sleeping, but starts the flying animation if being hit by something.
• blaze: Without the NoAI tag it randomly starts flying upwards.
• enderdragon: Without NoAI tag, it flies around, towards players, and pushes entities around. Shows boss bar.
• wither: Without NoAI tag, it makes noise. Shows boss bar.
• enderman: Teleports away / goes invisible when being hit by a projectile. Starts starring animation.
• silverfish: Without NoAI tag it is rotating wierdly depending on where the player is standing (possibly because it tries to rotate towards the player). Is constantly showing the movement animation.

• If the trade for a written book fails players can sometimes still open and read the book if they close the shop and click the temporary fake book in their inventory fast enough. There is not much I can do about this..
• Server crashes and improper shutdowns might cause living non-citizens shopkeeper entities to duplicate sometimes.
• The 'always-show-nameplates' setting is no longer working on MC 1.8.
• Compatibility with older bukkit versions is untested. If you encounter any problems let me know and I will look into it.
• When switching from a bukkit version which support mojang uuids to a bukkit version which does not support mojang uuids yet all stored owner uuids of player shops are lost.
• A bunch of entity types are only meant for experimental usage. They might cause all kinds of issues if used. See changelog of v1.50.
