Minor Changes

• #4220 c67a3d3b0 Thanks @davidkpiano! - Partial event descriptors are now type-safe:

  createMachine({
    types: {} as {
      events:
        | { type: 'mouse.click.up'; direction: 'up' }
        | { type: 'mouse.click.down'; direction: 'down' }
        | { type: 'mouse.move' }
        | { type: 'keypress' };
    },
    on: {
      'mouse.click.*': {
        actions: ({ event }) => {
          event.type;
          // 'mouse.click.up' | 'mouse.click.down'
          event.direction;
          // 'up' | 'down'
        }
      },
      'mouse.*': {
        actions: ({ event }) => {
          event.type;
          // 'mouse.click.up' | 'mouse.click.down' | 'mouse.move'
        }
      }
    }
  });
