+Agent 1.9.0 introduced `bank.settlement`: removal, rebuild, migration and creation
 cancellation finish pending TWS bank decisions before deleting the old runtime.
 An unavailable controller or corrupt journal leaves the operation unresolved
 and preserves storage. Update all agents before enabling the
 [player bank](bank.md). EC generates and injects bank credentials per instance;
 no token map or manual server-secret provisioning is required.

+Agent **1.9.1+** recognizes both the fixed public game-bank endpoint
+`https://ec.thewrightserver.net/api/bank` and its own legacy controller-derived
+bank endpoint in journals. It stops generating `tws_bank_url` in the private
+game configuration. Agent transport still uses the enrolled controller URL and
+host credential; journal URLs never determine request destinations. Upgrade
+agents first, then [rebuild servers changing bank endpoints](bank.md#upgrading-from-a-controller-derived-game-endpoint)
+to drain pending decisions before the new scripts start. See the
+[agent changelog](../../agent/CHANGELOG.md) for release and validation details.
