+'xstate': patch
+---
+
+When using a model type in `createMachine<typeof someModel>(...)`, TypeScript will no longer compile machines that are missing the `context` property in the machine configuration:
+
+```ts
+const machine = createMachine<typeof someModel>({
+  // missing context - will give a TS error!
+  // context: someModel.initialContext,
+  initial: 'somewhere',
+  states: {
+    somewhere: {}
+  }
+});
+```
