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 He systematically replaced outdated RNG calls across multiple files, ensuring that existing behavior was preserved while aligning the codebase with current Go standard library practices.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 reduced technical debt and improved maintainability, setting the stage for future extensibility. The work focused on code modernization rather than bug fixes, with no regressions observed. Khiem utilized his expertise in Go and the standard library to deliver a focused, well-scoped feature that enhances the project’s technical foundation.
