Version 8.3.7 introduces a permission check on the users.CreateToken API and enforces consistent room permission logic during channel‑to‑team conversions.

Why it matters: The new token generation permission check (severity 90) prevents unauthorized token creation; enforcing consistent room permissions during conversion safeguards access control for all affected flows.
