Membership pro and Invoice feature

I need a clarification about bills:

A subscribed user can see and download his invoices.
What appened when the user renew his subscription and insert new values in the fields?
Have the old bills (historicized) the new values? Otherwise, are old invoices historicized without to change the old values?

Thanks

Hi

When users renew his subscription, there will be new invoice created with the new data his entered (if he updated the data with new value)
