 As with all User / Contact accounts created in v8 no login is possible by those users until the administrator allows it and assigns a password so there is no security risk of Contact users logging in that previously could not.
 
+### Purchase orders / receipts
+Purchase orders and receipts have been combined in v8 and are no longer separate objects. 
+
+The various rules around Purchase order editing have been eliminated. In v8 purchase order editing ability is no longer controlled by their Status and a PO can be edited anywhere any time.  Behind the scenes AyaNova will make the necessary adjustments to inventory to support any edit changes made to purchase orders if they have already affected inventory or work order item part requests.  This allows for easy edits when things change post order, for example if a supplier has changed a price or an item has been replaced by another one after being ordered.
+
+Status is still available and can be set to any value at any time as users need for displaying in lists and controlling the process.  AyaNova itself will not set the PO status automatically at any time.
+
+### Part serial numbers
+Serial numbers have been separated from inventory for v8.
+
+They now reside in a collection of serials for each Part and you can select from the list or enter alternatives or none at all at any time.  This supports the many cases where users requested the ability to be more free-form with their serial numbers to allow for mistakes or unique needs but still record them in the system when they are consumed on work orders for warranty purposes etc.
+
+Importing from v7 will place any existing serials into the serial number collection automatically.
