Update to format of Catalog Reports.
Starting April 26, 2016, the format of Catalog Reports for apps and In-App Purchases will change. Instead of displaying each language as a column, reports will contain one column labeled "Locale."
Languages will be concatenated in this column using a pipe-delimited format. If you have an automated system that interacts with these reports, update it by April 26 to properly import the data in this new format.
