Sheep can't be dyed or sheared without permission.

Note: The client will still update the sheep color even when the event
is cancelled.  Reconnecting to the server or shearing the sheep (with
/ignoreclaims) will prove the sheep was not actually dyed.
Improved underwater claim management.

Better visualizations while the player is underwater, and both the stick
and shovel now point "through" water.
