In December 2024, delivered a key API enhancement for the Username Override Function in the heroiclabs/hiro repository. The UsernameOverrideFn API now accepts a requested username parameter, enabling custom username generation functions to inspect and validate incoming username requests. The function returns a string, with an empty string signaling Nakama's default behavior. This change improves customization, validation, and policy enforcement during user signup while preserving a robust fallback path. The update aligns with efforts to enhance security, user experience, and auditability in identity flows. (Commit: 1bb68905e54ff4b42b2df977aa86f78c8ea39a8e, #75)
