Slight changes to handling saving: If there is a problem during the saving it waits a bit and then retries several times. This might help if for some reason the save file can only temporary not be written to (for example because of some other application, like Dropbox, currently locking the file). It also checks for some other possible causes of issues, like if the parent directory is missing (if it is, it attempts to create it). It also checks if it currently can write to the save file, before removing the old save file. These changes hopefully prevent that certain issues cause the save data to go completely lost. Also it prints some more information to the log if it detects some issue.
Fixed: A bug in minecraft's trading allowed players to exploit certain trade setups (only very few trade setups are affected though). Shopkeepers is now detecting and preventing those affected trades.
Added (API): The ShopkeeperTradeEvent now holds information about the used trading recipe, and the ShopkeeperTradeCompletedEvent holds a reference to the original ShopkeeperTradeEvent.
Added (API): A bunch of javadoc was added or updated for the available events.
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.
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.
In the latest MC 1.8.x versions default minecraft trading logic has slightly changed (and by that those of shopkeepers as well): if a trade requires an item with special data (like a custom name, etc.) minecraft is now only allowing this trade, if the offered item is perfectly matching, including all special item data and attributes.
