During July 2025, Khiem Doan modernized the random number generation infrastructure in the projectdiscovery/utils repository by upgrading legacy code to use Go’s math/rand/v2 API. He systematically replaced outdated RNG calls across multiple files, ensuring that existing behavior was preserved while aligning the codebase with current Go standard library practices. This refactor focused on maintainability and future extensibility, reducing technical debt without introducing regressions. Khiem’s work leveraged his expertise in Go and the standard library, delivering a targeted feature that improved code ergonomics and set the stage for future enhancements, though it did not involve direct bug fixes within this period.
