Bukkit

v1.41 for MC 1.6.2, 1.7.x, 1.8.x

• No longer storing owner uuids of player shops if running on a bukkit version which does not support mojang uuids yet. This helps if you have already stored those 'invalid'/non-mojang player uuids by running v1.40, however it has the disadvantage that you loose all stored owner uuids if you switch back to an older bukkit version after you have already run a newer bukkit version which supports mojang uuids!
• Ignoring the owner uuid now when finding inactive shops if not running on a bukkit versions which supports mojang uuids yet.

Also please take a look at the changelogs of the versions since v1.20 for all not yet fully documented changes!

• 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.
• 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.

Also please take a look at the changelogs of the versions since v1.20 for all not yet fully documented changes!
