+The `serializeState()` path traversal option now provides 3 arguments to the function passed in:
+
+1. `state` - the current state
+2. `event` - the event that caused traversal to this state
+3. `prevState` 🆕 - the state before the current state (may be `undefined`)

+Substantially simplified how paths and plans work in `TestModel`. Changed `getShortestPlans` and `getSimplePlans` to `getShortestPaths` and `getSimplePaths`. These functions now return an array of paths, instead of an array of plans which contain paths.
+
+Also added `getPaths`, which defaults to `getShortestPaths`. This can be passed a `pathGenerator` to customize how paths are generated.

+Added validation on `createTestModel` to ensure that you don't include invalid machine configuration in your test machine. Invalid machine configs include `invoke`, `after`, and any actions with a `delay`.
+
+Added `createTestMachine`, which provides a slimmed-down API for creating machines which removes these types from the config type signature.

+`getShortestPaths()` and `getPaths()` will now traverse all _transitions_ by default, not just all events.
+
+Take this machine:
+
+```ts
+const machine = createTestMachine({
+  initial: 'toggledOn',
+  states: {
+    toggledOn: {
+      on: {
+        TOGGLE: 'toggledOff'
+      }
+    },
+    toggledOff: {
+      on: {
+        TOGGLE: 'toggledOn'
+      }
+    }
+  }
+});
+```
+
+In `@xstate/test` version 0.x, this would run this path by default:
+
+```txt
+toggledOn -> TOGGLE -> toggledOff
+```
+
+This is because it satisfies two conditions:
+
+1. Covers all states
+2. Covers all events
+
+But this a complete test - it doesn't test if going from `toggledOff` to `toggledOn` works.
+
+Now, we seek to cover all transitions by default. So the path would be:
+
+```txt
+toggledOn -> TOGGLE -> toggledOff -> TOGGLE -> toggledOn
+```
