Hi there. Version 1.01 has conditional dependence on Text::CSV_PP, so if it cannot find Text::CSV_XS it will use that instead. You shouldn't need a C compiler like in 1.00. As for what the later versions bring you: stability and updated handlers for the various sites that provide this information. One of the more visible consequences of this is that you can now have open-ended dates. Specifying no dates at all will get the entire known history of a ticker. Cheers, Matt
