In May 2025, delivered a focused documentation update for the Firely Auth client registration lifecycle. The update clarifies that client registration is processed only at the initial startup, and directs admins to use the User Interface or API for subsequent client management to ensure proper configuration and operational procedures. This reduces misconfiguration risk and aligns operational practice with startup behavior.
