During July 2025, the team delivered customer-value features and cleaned up configuration reliability across two repositories. In generiekzaakafhandelcomponent/Plugins, we fixed a critical configuration form issue in the Rotterdam Oracle ESB plugin, eliminating duplicate fields and incorrect control names, and updated the plugin version to reflect the fix. We also added a new invoice reference property (factuurKenmerk) to the sales invoice plugin, updating backend Kotlin, frontend HTML, TS config, and multilingual plugin properties/specifications to support an additional invoice reference. In valtimo-platform/valtimo-documentation, we consolidated Zaken API plugin documentation, added Patch Zaak action details, standardized field naming and capitalization across configure-zaken-api-plugin.md, and corrected the field name casing for 'Communication channel name'. These changes collectively improve data integrity, developer experience, and cross-language consistency.
