If requested by the user, the ChartDownloader fetches charts for the Slovakian section of the Danube which were updated in 2010. Charts updated in 2013 are available, and the ChartDownloader should get these newer charts.
Here is the URL to a webpage in English

in order to download the newer charts (updated in 2013). The dates in the catalog will also need to be changed.
I have downloaded both the 2010 and 2013 charts. The newer charts have depth
contour lines and more shoreline detail.
