0.17.4

• Improved upgrade support.
  • The CloudFormation upgrade stack operation from the AWS Console should now be used to
    change configuration using the available parameters. After the upgrade is complete, the
    lex-web-ui-loader-config.json file deployed to the web app S3 bucket will be updated
    with the values specified in the template. Prior versions of the config file are archived
    using a date timestamp in the S3 bucket should you need to refer to prior configuration values.
  • Users can now upgrade to new versions of Lex-Web-Ui using the AWS CloudFormation console
    by replacing the template and specifying the S3 template location from the original regional
    S3 bucket. As new releases of Lex-Web-Ui are published to the distribution repositories, you
    can now upgrade to this version using the CloudFormation Upgrade/replace template process.
  • After an upgrade, the CloudFront distribution cache will need to be invalidated for the changes to be seen
    immediately.
  • Regional upgrade distribution locations

• Chat history can now be preserved and redisplayed when the user comes back to the original parent page
  hosting the Lex-Web-Ui. This features is controlled using the SaveHistory template parameter. When
  this feature is enabled, a new menu is visible in the user interface that allows the user to
  clear chat history. The following are the methods you can enable this feature. Note that you can
  toggle this feature on and off using the upgrade process.
  • During a new deployment, specify true for the Save History parameter
  • Using the new upgrade feature, specify true for Save History parameter in the CloudFormation
    console.
