Prestashop 1.7.6.0 and higher have a new table: ps_currency_lang.
Until version 0.36 Copy_shopdata doesn't list this table in the config file. As a consequence copying tables may result in missing currency translations. That causes a "Missing Locale" error.
In version 0.37 ps_image_type has been removed from the list of copied tables. At closer look its presence wasn't a good idea.
In version 0.38 localhost and 127.0.0.1 are considered the same so copying happens now direct instead of via the file system. Also a bug was fixed that made copying over the file system go wrong when tables didn't have the same fields.
Version 0.39 added some fields that are copied.
