Bukkit

2.3 Updates!

• More witches.

• Creepers now have a small chance to drop primed TNT when slain (that's your cue to run like hell).

• Torches will no longer attach to common soft blocks like dirt, grass, and sand. Players can "stick to" trees and stone in caves, but will need to place a block to illuminate open wilderness areas.

• Updated TNT explosions to be way cooler (roughly the same power).

• Players will no longer lose 100% of their inventories when a charged creeper sneaks up on them (that was a bug).
