+| NRC       | Improved Hangfire retry handling for webhook delivery failures.               | Webhook processing recovers automatically after transient failures, improving reliability of callback delivery. | Notificaties bereiken eindgebruikers betrouwbaarder, met minder verstoringen na tijdelijke storingen.        | Achtergrondtaken herstellen zichzelf, minder handmatige interventie nodig. |
+| ZRC       | Removed legacy BSN column `inpbsn` from database.                             | Deprecated internal field inpBSN removed.                                                                       | Minder risico op datalekken.                                                                                 |                                                                            |
+| ZRC/BRC   | Enforced uniqueness: `identificatie+owner` combination now guaranteed unique. |                                                                                                                 | Geen dubbele zaak-/besluitnummers meer, ook niet als externe applicaties foutieve bronorganisaties invoeren. |                                                                            |
+| ZSDMS/DRC | Added retries for token renewal Hangfire jobs.                                |                                                                                                                 | Document- en berichtverwerking stabieler na onderhoud of storingen. Hierdoor betere data consistentie.       |                                                                            |
