  105:     migrate:
  106: 
  107:       # Before
  108:       md = Digest::MD5.new("string")
  109:       # After (works with any version)
  110:       md = Digest::MD5.new.update("string")
  111:         
  112:       # Before
  113:       hd = Digest::MD5.new("string").hexdigest
  114:       # After (works with any version)
  115:       hd = Digest::MD5.hexdigest("string")
