Rails - Nov 2008 - easy before_update question (i hope)

in a before_update is there an easy way to check if a specific field
is being changed?

for example

def before_update
  unless current.email == new.email
    # do stuff
  end
end

obviously "current.email" and "new.email" are wrong. i am
guessing one
will be "self.email", what would the other be?
