Bukkit

Compatibility

You need the CraftBukkit build for MC 1.5.1 R0.2 (or maybe later?) for this to work, otherwise be careful and make a server backup beforehand. There is no guarantee that it will work on older or newer versions of CraftBukkit. You also need at least BKCommonLib v1.51.

Changelog

• Performance fixes for chunk persistence, item crafting, transferring and others
• Physics fixes for vertical rails, switcher signs
• Addition of per-cart exit offsets and exit offset properties
• Ejector sign bugfixes and logic changes so it uses the cart offset property
• Minecart/train item drops property added to disable drops per minecart/train
• General compatibility update for MC 1.5.1 (new minecart types, controllers, network sync fixes)
• Fixes related to redstone powering and station signs
• Support for mob spawner minecart added with ability to alter spawned entity type and interval
• Fixed permission problem when placing signs/destroying
• Added: rail directions can now be altered by right-clicking rails with the same rail type item
• Added: TrainCart placement permission (allows both regular and TrainCart minecarts on the server)
• Bugfixes related to minecart restoring on startup (part of it caused by CB changes)
• Fixed: server freezing when using the train name property sign
• Added: Transfer sign width and height radius, with in/outward sorting
• General rewrite of most of the TrainCarts code to support the new Entity Controller system

Reported but failed to replicate (could be a plugin conflict):
- Train keep chunks loaded not always working
If you have this problem, please post the list of plugins you use. In the meantime, you can use other 'minecart persistence' plugins to do this. They use a larger radius to fix the synch gap, so they load a lot more chunks than needed, but if it helps, use it.
