In fact, the changes are deeper. In both types of reports, the fields have been updated: in the "Client's contact" field you can see the email from which the request has been done, and the field "Client's mail" has all known email addresses of the client.
If there are several email addresses, they will be specified in the "Client's mail" field, separated by commas. Thanks to the new fields, all the clients' e-mail addresses are uploaded to the reports, and there is no data loss.
