           diff: use the array-diff feature. This will reduce the amount of
           traffic for large arrays in which only a few elements change.
           Note that in multidemensional arrays, the individual sub-arrays
           only get diff'd if the higher levels have constant length.
           add-cap: only transfer this field if the given capability is
           available at runtime. If you have a capability named
