Bukkit

v2.2.0

• Config system now uses Materials instead of item and block IDs. Please see https://github.com/Bukkit/Bukkit/blob/master/src/main/java/org/bukkit/Material.java for a list of all Materials
• Improved reflection to vanilla classes and methods

• Blocks will be placed on any other block. For example, saplings will grow on sand, grass, and everything else
