Bukkit

ChangeLog:

• No longer registers for all packets in ProtocolLib - reduces lag as it was not supported that well
• Added a lot of new utility classes to safely deal with internal logic such as NBT, data watchers and base classes
• Added a full conversion system to convert between all possible types of objects, to make life easier
• General reflectionization (is this a good thing?) in an attempt to make updating faster
• Added a lot more packet related routines, such as new constructors and fields
• Added proper detection mechanisms for incompatibility
• Metrics rewritten and improved to make it easier, and allow more control to the end-user
• Added InterpolatedMap to deal with linear interpolation in a dataset (fuzzy logic, sort of)
• Fixed countless of errors and issues related to reflection going hostile
• Added helper methods to get nearby entities and block states near a block
• Added more MaterialUtil 'IS<something>' constants, plus toString mechanism for conversion to ItemParsers
• Added BlockInfo helper class to deal with common (non-Bukkit supported) block operations and properties
• Fixed NPE occurring with certain entity types being requested the name of
• Added several new world utilities, such as to disk saving and chunk availability
• Fixed permissiondefaults.yml always using a '*' by default
• Fixed stackoverflow when crafting self-craftables (sandstone for example)
• A lot new reflection helper classes added for various purposes, including proper type conversions
• Added stack trace filters to make errors contain less and more useful information
• Fixed silent packet being detected anyhow in some plugins (Orebfuscator)
• Added classpath to plugin conversion, to find out the cause of errors or the owners of classes
• Fixed entity teleportation, now properly teleports vehicles and passengers again
• Generally erased all exposure of NMS and CB types, to push for forwards and backwards support in plugins

WARNING: This version may break some of your plugins using BKCommonLib (They will/must all be updated)

Known to conflict with SpoutPlugin and possibly other plugins that replace packet listeners. To remain compatible, install ProtocolLib.
