Bukkit

New features

• Added smoke particle effect to the double jump. (configurable)

New permission

• jumpplus.bypass.gravity: allows user to double jump without receiving fall damage. Defaults to OP.

New configuration

• fallModifier: Set the fall distance modifier. Positive means less fall damage, negative means more fall damage. Accepts integer.
• particleEffect: Set whether to show visual particles on double jump or not. Accepts boolean.

Bug fixes

• Solved bug if using Shift while on the edge of a block.

Jumping on the same place (either normal jump or double jump faced down) won't reset the jump count. This is because double jumping is enabled everytime the player is airborne. If the player either changes his view (i.e. move mouse) or jump with even an slight difference in position, the jump count will reset normally. Still looking for a proper solution.

Particle effect config and fall damage were overlooked. Will fix in next version.
