• Update aws sdk to current revision
• Change codebuild-deploy.yaml to use amazon linux image vs nodejs10 image.
• Change codebuild-deploy.yaml and pipeline.yaml buildspec and codebuild role to invalidate cloudfront distribution after syncing s3 bucket
• Fix Lex V2 client state mapping - specific for audio
• Enhance Lex V2 support to
  • allow configuration of multiple V2 locale ids via template in comma separated list
  • provide menu based selection of configured V2 locales
• Enhance postMessage to better filter messages between iframe and parent
• Make CognitoAppUserPoolClientId and CognitoUserPoolId optional in master-pipeline.yaml

• Move from webpack V3 to webpack V4 in the lex-web-ui component.
• Move to npm version 7.10.0.
• Update component package versions.
• Resolve some dependabot alerts.
• Fix to resolve update problem where Cognito Supported Identity Providers is reset to just Cognito. An update will now preserve the existing Supported Identity Providers.
• Set AWS sdk to version 2.875.0.
• Improve Lex V2 support to handle responseCard defined as a session attribute in sessionAttributes.appContext.responseCard.
• Removed support for AWS Mobile Hub based distribution.

• New support for Lex Version 2 Bots - added template parameters for V2 Bot Id, Bot Alias Id, and Locale Id. When a V1 Bot name is provided, the template will configure resources to use the V1 bot. When the V1 Bot name is left empty and the V2 Bot parameters are specified, the template will configure resources to use the V2 Bot. V1 Bot parameters take precedence over V2 Bot parameters if both are supplied.
• The Lex Web Ui can now be configured to send an initial utterance to the bot to get an intent started. A new template parameter named WebAppConfBotInitialUtterance is available. If left empty, no initial utterance is sent to the Bot which is the default behavior.
• Changed format of the date message displayed on a message to use "n min ago" to assist with accessibility when displaying this value.
• Changed behavior of ShouldLoadIframeMinimized setting. In prior releases, the last known state of the iframe took priority over this setting. In this release, when ShouldLoadIframeMinimized is set to true and the parent page is loaded or refreshed, the Bot iframe will always appear minimized. If this parameter is set to false, the last known state of the Bot is used to either show the iframe or minimize the iframe.
• Changed loginutils.js to prevent the parent page or the full page from looping if login fails through cognito. With this change, up to 5 attempts will be performed before failing with an alert message presented to the user.
• Support mixed case web ParentOrigin URLs and WebAppPath in Cognito user pool to prevent login failures due to case mismatch.
• Support multiple values for WebAppPath. This allows the LexWebUI with login enabled to be deployed on multiple pages on the same site (origin).
• Update the Cognito Callback and Signout URLs in the Cognito UserPool when ParentPageOrigin and WebAppPath parameters are updated in CloudFormation.

• Fix for pipeline based deployments - issue 264 - template error
• Fix to full page web client (index.html) using forceLogin to require a direct to login page
• Fix to move to python 3.8 Lambda Runtime for yaml CloudFormation template embedded functions which remove use of boto3 vendored library
• Add ability for Lex Web UI to automatically retry a request if the Lex bot times out after 30 seconds using a configurable number of attempts. By default the timeout retry feature is disabled. When enabled, the default retry count is 1.

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.
