Saving data in format 2.0 to 2.4

The saving of data in SAMSON Valve Sizing format 2.0 to 2.4 could result in loss of data. Save anyway?

This message appears if you want to save an item file in the old file format so that it can be read by the previous versions (2.0 to 2.4) of SAMSON Valve Sizing. You should note, however, that new options and functions that were not included in these previous program versions, e.g. valve body types for self-operated regulators, cannot be saved or reloaded.
