Jan 1, 2025Monthly summary for 2025-01 (google/nearby): Implemented a refactor to clarify pending connection state by renaming the BasePcpHandler parameter from connection_info to pending_connection_info across related functions. This change enhances API clarity, reduces ambiguity in the NearbyConnection workflow, and lays groundwork for safer future changes. No major bugs were reported this month. Key impact includes improved maintainability, easier onboarding for engineers, and stronger alignment with the module's pending-state semantics. Tech notes: code refactor, naming consistency, and commit traceability (see ed79ce5f03b94ea96466ce799c065106f8c5b5e1).
