 # @xstate/graph
 
+## 2.0.0-alpha.0
+
+### Major Changes
+
+- [#3036](https://github.com/statelyai/xstate/pull/3036) Thanks [@davidkpiano](https://github.com/davidkpiano)! - @author: @davidkpiano
+
+  Renamed `getAdjacencyMap` to `getValueAdjacencyMap`.
+
+* [#3036](https://github.com/statelyai/xstate/pull/3036) Thanks [@davidkpiano](https://github.com/davidkpiano)! - @author: @davidkpiano
+
+  Changed `getSimplePaths` to `getSimplePlans`, and `getShortestPaths` to `getShortestPlans`. Both of these functions can be passed a machine, and return `StatePlan[]`.
+
+  Added functions `traverseSimplePlans`, `traverseShortestPlans`,`traverseShortestPlansFromTo`, `traverseSimplePlansTo` and `traverseSimplePlansFromTo`, which can be passed a `Behavior` and return `StatePlan[]`.

 # @xstate/test
 
+## 1.0.0-alpha.0
+
+### Major Changes
+
+- [#3036](https://github.com/statelyai/xstate/pull/3036) Thanks [@davidkpiano](https://github.com/davidkpiano)! - @author: @mattpocock
+  @author: @davidkpiano
+
+  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.
+
+* [#3036](https://github.com/statelyai/xstate/pull/3036) Thanks [@davidkpiano](https://github.com/davidkpiano)! - @author: @mattpocock
+
+  Moved event cases out of `events`, and into their own attribute called `eventCases`:
+
+  ```ts
+  const model = createTestModel(machine, {
+    eventCases: {
+      CHOOSE_CURRENCY: [
+        {
+          currency: 'GBP'
+        },
+        {
+          currency: 'USD'
+        }
+      ]
+    }
+  });
+
+  model.getPaths().forEach((path) => {
+    it(path.description, async () => {
+      await path.test({
+        events: {
+          CHOOSE_CURRENCY: ({ event }) => {
+            console.log(event.currency);
+          }
+        }
+      });
+    });
+  });
+  ```
+
+  `eventCases` will also now always produce a new path, instead of only creating a path for the first case which matches.
+
+- [#3036](https://github.com/statelyai/xstate/pull/3036) Thanks [@davidkpiano](https://github.com/davidkpiano)! - @author: @davidkpiano
+
+  Removed `.testCoverage()`, and instead made `getPlans`, `getShortestPlans` and `getSimplePlans` cover all states and transitions enabled by event cases by default.
+
+* [#3036](https://github.com/statelyai/xstate/pull/3036) Thanks [@davidkpiano](https://github.com/davidkpiano)! - @author: @davidkpiano
+
+  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.
+
+- [#3036](https://github.com/statelyai/xstate/pull/3036) Thanks [@davidkpiano](https://github.com/davidkpiano)! - @author: @davidkpiano
+
+  `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
+  ```
+
+* [#3036](https://github.com/statelyai/xstate/pull/3036) Thanks [@davidkpiano](https://github.com/davidkpiano)! - @author: @mattpocock @davidkpiano
+
+  Moved `events` from `createTestModel` to `path.test`.
+
+  Old:
+
+  ```ts
+  const model = createTestModel(machine, {
+    events: {}
+  });
+  ```
+
+  New:
+
+  ```ts
+  const paths = model.getPaths().forEach((path) => {
+    path.test({
+      events: {}
+    });
+  });
+  ```
+
+  This allows for easier usage of per-test mocks and per-test context.
+
+- [#3036](https://github.com/statelyai/xstate/pull/3036) Thanks [@davidkpiano](https://github.com/davidkpiano)! - @author: @mattpocock @davidkpiano
+
+  Added `states` to `path.test()`:
+
+  ```ts
+  const paths = model.getPaths().forEach((path) => {
+    path.test({
+      states: {
+        myState: () => {},
+        'myState.deep': () => {}
+      }
+    });
+  });
+  ```
+
+  This allows you to define your tests outside of your machine, keeping the machine itself easy to read.

+### Minor Changes

+- [#3036](https://github.com/statelyai/xstate/pull/3036) Thanks [@davidkpiano](https://github.com/davidkpiano)! - @author: @mattpocock @davidkpiano
+
+  Added `path.testSync(...)` to allow for testing paths in sync-only environments, such as Cypress.
