+This module is compatible with OpenERP 6.0.
+
+The IBAN module in OpenERP 6.1 registers the IBAN
+on the same field as the domestic account number, 
+instead of keeping both on separate fields as is the
+case in 6.0. That means that an upgrade to OpenERP 6.1
+makes you lose this information. If you want to keep
+the domestic account number in addition to the IBAN,
+install this module prior to the upgrade to OpenERP 6.1. 
+
+Do *not* install this version of the module on OpenERP 6.1.
+A dedicated module for OpenERP 6.1 will be available that
+allows you to access the domestic account number.
