November 2025: Delivered two strategic enhancements for smartcontractkit/chainlink that strengthen compatibility, correctness, and deployment reliability. Upgraded the Chain-Selectors dependency from v1.0.77 to v1.0.78 across multiple modules to align with the latest features and fixes and to maintain cross-module compatibility. Improved contract ownership validation by enabling ValidateOwnershipOfChain to accept a map of owned contracts and by improving error messages, ensuring all contracts are validated against their expected owners. These changes reduce ownership misconfig risk, improve maintainability, and accelerate downstream deployments by providing clearer diagnostics and faster issue identification.
