 == Changes to BIS document
 
+
+== Changes to code lists and validation artefacts
+
+* Invoice Type codes 326 (Partial invoice) and 384 (Corrected invoice) added to the codelist and listed as synonyms with type code 380 (Commercial Invoice)
+* German country specific validation rules added.
+* The rule (PEPPOL-EN16931-R002), which ensures that the Invoice Note (BT-22) appears no more than once, will not apply if both the buyer and seller are German organizations.
+* Update for rule NL-R-008 (mandatory payment means), the check should not fire if the document is a credit note with a positive amount.
 * sample files and snippits have been updated to reflect the new rule PEPPOL-EN16931-R131
