Minor Changes

• 4f2f626d #2143 Thanks @davidkpiano! - Tags can now be added to state node configs under the .tags property:

  const machine = createMachine({
    initial: 'green',
    states: {
      green: {
        tags: 'go' // single tag
      },
      yellow: {
        tags: 'go'
      },
      red: {
        tags: ['stop', 'other'] // multiple tags
      }
    }
  });

  You can query whether a state has a tag via state.hasTag(tag):

  const canGo = state.hasTag('go');
  // => `true` if in 'green' or 'yellow' state
