     * 
     * Breaking changes includes:
     * - DECIMAL types returned as strings.
     * Proper solution is to use a BigNumber library of some sort to
     * handle large numbers safely.
     * - JSON types are parsed and returned as actual objects as strings.
     * 
     * When this setting is false, DECIMAL types are returned as JS numbers
     * and JSON types are returned as strings, requiring the application to JSON parse the data.
