+### Fixed

+- Potentially breaking fix: resolved mismatch between `RouteSelectionExpression` in deployed Architect apps vs. locally in Sandbox
+  - The `RouteSelectionExpression` is now `$request.body.action`, meaning WebSocket code running locally (but not on AWS) should be updated from `ws.send(JSON.stringify({ message: 'custom-endpoint', ... }))` to  `ws.send(JSON.stringify({ action: 'custom-endpoint', ... }))`
+  - This fixes #768; thanks @mawdesley + @MartinRamm!
