December 2025: Delivered a foundational time-range capability across UDM search, security event search, and CSV export in google/mcp-security, enabling precise historical queries with start_time and end_time support. Implemented a centralized time parsing utility, added robust validation and timezone-aware handling, and expanded test coverage to improve reliability and maintainability. This work enhances data operability, reduces query guesswork, and improves developer experience through better tooling and testing.

June 2025 monthly summary for firebase/firebase-js-sdk: Delivered modular typings generation for google3 environments. Implemented Rollup configuration and rollup-plugin-dts in analytics and remote-config to generate global_index.d.ts, enabling internal google3 builds to use modular typings. This work reduces cross-package typing friction, standardizes internal typings distribution, and lays groundwork for broader modular typings adoption across the SDK. Commit 13e6cce882d687e06c8d9bfb56895f8a77fc57b5: Feat/google3 typings support (#9085).
