Twilio Changelog

Flex’s Messaging Channel Janitor is now on by default for any new Flex messaging configurations (Flex Flows) created within the Twilio Console, as well as the default Flex Flows created for new Flex accounts.

Channel Janitor cleans up the chat channel and Proxy sessions for completed tasks, keeping them in sync with TaskRouter and making sure that when an existing customer contacts again, a new conversation is started.

Flex Flows are the configuration entities mapping phone numbers to Flex (one Flex Flow per phone number). Channel Janitor is enabled/disabled per Flex Flow. To enable Channel Janitor for existing Flex Flows, you can use the Flex Flow API or the Flex Messaging page in the Twilio Console.

You can learn more about the Channel Janitor and long-lived channels in Flex messaging documentation.

.Admins and developers managing self-hosted Flex applications can now use the “Login with Twilio” option to access Flex without Single Sign-On. These users can login to Flex with admin privileges if they have been added to the account within the Twilio Console.

Review our SSO guide for more details and for help configuring Flex Single Sign-On.

This release of Flex UI introduces new filter options for the Teams View. With Hidden Filters, your developers can control which users each supervisor is able to view and manage. This is useful if you want a supervisor to only manage their team, instead of being able to view all agents by default.

You can now update your Flex application to use the latest version of React and ReactDOM. This allows you to use React’s newest APIs, including React Hooks, when developing your Flex plugins.

This feature is available in Flex UI v1.19 and above. You can update your application to use the latest React version on the Pre-Release Features Page. For more details, visit our React documentation.

We have updated all Flex projects that use Automatic Updates to Flex UI 1.20.

This release of Flex UI introduces image and file sharing for chat channels in Flex. Agents and webchat users can now share images, documents, and other files during a chat conversation. This is currently available as a Pilot feature. You can learn more about this feature and how to enable it within our documentation.

Other notable features include:

• Notification to signal connectivity issues: Users will now be notified if Flex UI has lost network connectivity and is trying to reconnect.
• Initialization error page: If Flex UI encounters an error during initialization, users will now see details of the error and they can download a report which will provide technical details for troubleshooting.
