You can now choose how long an API token lives when you create it. The create form has an Expires in control whose choices follow the token type: personal tokens can last 7, 30 or 90 days, and service tokens, which never expired before, can now be set to expire after 30, 90 or 365 days.
If you leave the control on its default, nothing changes. Quint enforces each type's ceiling on the server, so a lifetime longer than the type allows is refused instead of being quietly extended.
