Bukkit

• Updated for Minecraft 1.5 (should still work with 1.4.7 as well).
• Several config options have been added, changed, or deleted. See Configuration Options for more information.
• Added support for all items with meta information (fireworks, enchanted books, custom potions, etc). Renamed items and items with lore are also supported.
• Added tooltips for the editor window action buttons.
• Removed the "Save" action button (just close the editor window to save).
• Added the "Set Shop Name" action button, which allows you to set a shop's name. This sets the nameplate for the villager as well as the trade window text.
• Added the witch as a shopkeeper type.
• Shopkeeper creating has been unified. Right-click in air while holding the creation item (villager egg by default) to select the type of shop (normal, buy, trade). Hold sneak while you right-click in air to choose the shopkeeper type (villager, sign, witch). Then right-click on a chest then on a block as usual to place the shop.

I highly recommend you back up your save.yml file in the Shopkeepers folder. I've made some changes to the save file format, and in the event that I made an error, it will be nice to have a backup.
