Twilio Changelog

Studio now supports SSML tags when using Amazon Polly voices in Say/Play and Gather Input On Call widgets.

To enable SSML, select a default Polly voice from the Text-to-Speech Settings in Twilio Console or select one from the Voice dropdown menu on the Studio widget.

Add the SSML tags you wish to use directly in the Text to Say field.

We have updated all Flex projects that use Automatic Updates to Flex UI 1.32.

This release of Flex UI introduces a Degraded mode for Flex UI and improvements to Status Report. Now Flex UI will initialize with limited capabilities, even if some of the components like SDK’s (TaskRouter, Conversations, Voice or Sync) are down. The Status Report is now available in GA and includes debugger logs, Twilio service status information and whether Flex UI is running in degraded mode.

For more information check our documentation. Check how to enhance and customize queues monitoring programmatically.

For more details on this release, please visit the release notes for Flex UI.

Reminder: You can pin to individual versions of the Flex UI or manage your Automatic Updates within the Flex Admin UI.

We are excited to announce that Flex UI 2.0 is now available in GA.

We are excited to announce that Flex Conversations is now Generally Available.

• Support for Conversations API, the single API to manage all asynchronous channels including SMS/MMS. WhatsApp, and Chat
• New Interactions API to set up and manage inbound and outbound communications
• An open source React based chat application to help you get started with creating and embedding webchat into your website

Flex Conversations requires Flex UI 2.0. See the Flex UI 2.0 docs for more info and how to perform a migration.

You can read more about this launch on our blog, and if you’re ready to start building, dive into our docs.

The Twilio Programmable Voice SDKs now offer the new Call Message Events: User-Defined Messages and User-Defined Message Subscription resources for application developers. This first release, available in Public Beta on the latest major versions of Voice JS and iOS SDKs, supports relaying custom events to and from your backend to a registered Voice SDK Client on established calls - all within the Twilio platform. This unlocks a host of advanced use cases, including:

• Relaying (and taking action on) call progress events
• In-line text transcriptions
• Upgrading 2-party call to multi-party via Voice Conference
• Present valuable context in your application at the right time

Check out the docs for more information on how to use the new Call Message Events: User-Defined Messages functionality in your application. We can’t wait to see what you build!

The change we announced in March 2022 to API response headers for all SMS and MMS messages sent via Twilio’s Messaging APIs has been canceled. The updates to our terms and policies, which were jointly announced with the potential pending content verification API response header change, are unaffected by this announcement and remain in effect.

Twilio continues to strive for high message deliverability and to keep consumers safe. Thank you for doing your part in promoting trusted communications by ensuring your compliance with Twilio’s Acceptable Use Policy and Messaging Policy and securing proper consent from senders and recipients before messages are sent.

The previous-generation language models that are currently available with IBM Watson Speech to Text AddOn will be deprecated and stop functioning as of March 3rd 2023. To avoid any issues with transcribing your call recordings use IBM Speech To Text AddOn, please update to use next-generation language models as soon as possible.

The following table has the mapping between previous generation language models, and the next generation language models to make it easier for you to make appropriate changes. We recommend that you make this change at your earliest convenience.

Twilio SendGrid has launched support for Domain Connect with GoDaddy to improve the Domain Authentication process. The updated Twilio SendGrid user interface eliminates the need to manually copy and paste CNAME records from Twilio SendGrid to GoDaddy, allowing you to onboard more quickly and start sending mail. Customers are now able to click a button and sign into their GoDaddy accounts from within the SendGrid platform. Twilio SendGrid will then authenticate their domains automatically by making the necessary DNS entries for them.

There are no other changes to existing capabilities. No action is required for customers at this time.

We are keeping your runtime up to date in accordance with industry standards. Based on the Node.js support schedule, Node.js v14 will no longer be in Maintenance long-term support (LTS) status after April 30, 2023. Production applications should only use releases of Node.js that are Active LTS or Maintenance LTS.

Your currently deployed functions will continue to execute on the existing Node.js v14 runtime if no changes are made.

Follow these instructions to upgrade, test, and deploy your code and ensure a safe transition to Node.js v16.

This release improves Flex UI’s resiliency by updating functionality used in conferences, outbound calling and voice transfers to remove dependencies.
