November 2025 delivered performance, robustness, and governance enhancements across ConductionNL/openregister and ConductionNL/openconnector. Key features delivered include parallel rendering of objects, organization management and multi-tenancy adjustments with improved dependency injection, and config-driven controls for safer operation. Migration safety checks ensure extend-column migrations run only when safe and when the relevant table exists, reducing risk in schema changes. In openconnector, governance improvements were complemented by log retention policy work. The combined work improved system throughput, tenant isolation, migration safety, and observability while delivering clearer configuration and security guarantees.
