    ```ts
    setup({
      schemas: {
        events: {
          go: types<{}>()
        }
      }
    }).createMachine({
      states: {
        active: {
          on: {
            go: (_args, enq) => {
              enq.raise({ type: 'go' });
            }
          }
        }
      }
    });
    ```

-   4b5b14f: Transition functions may now return only a target when the target state's context is compatible with the current context.

    ```ts
    setup({
      schemas: {
        context: types<{ count: number }>(),
        events: {
          next: types<{}>()
        }
      }
    }).createMachine({
      context: { count: 0 },
      initial: 'idle',
      states: {
        idle: {
          on: {
            next: () => ({ target: 'done' })
          }
        },
        done: {}
      }
    });
