+
+### 🐛 Bug Fixes
+
+* updateZaak when deleting an existing gerelateerde and add new one back on the same role performs add action before delete action resulting in an error when only 1 of that roltype is allowed ([34ff319](https://github.com/wearefrank/zaakbrug/commit/34ff319fd990a824b885bcd473ff4fe8160537a6))
+
+### ✅ Tests
+
+* change delete&add roles testcase to use initiator instead so that order of operation is checked aswell ([ac0cade](https://github.com/wearefrank/zaakbrug/commit/ac0cadea0d99fcf3ab8d0c2d5fc5a1a66d5bf297))
