Twilio Changelog

We have updated all Flex projects that use Automatic Updates to Flex UI 1.12.

This Flex UI release introduced the AudioPlayerManager API, a dialpad for sending DTMF tones during an active call, and performance improvements to the Teams View. For a full changelog, visit the Flex UI release notes.

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

The new version of Marketing Campaigns now provides a sample of 50 contacts within the UI for any given segment. To view all contacts included in a segment at any given time, users can use the export option.

Every account with subaccounts will now have the option to get notified about subaccount level errors/warnings through a single webhook endpoint. It means that if you choose the option to Include errors and warnings from my subaccounts, Twilio will post new errors and warnings from your subaccounts to the debugger webhook endpoint you configure on the debugger Settings page.

Note: This will only work for accounts with subaccounts. Create a subaccount to test this feature.

The Differentiated Services Code Point (DSCP) Tagging API allows you to mark the audio packets with Expedited Forwarding (EF) and video packets with Assured Forwarding (AF) for the purposes of prioritised packet routing. When enabled, supporting networks will prioritize audio and video packet delivery for improved audio and video quality. Note, only Chrome supports DSCP tagging.

For more information, refer to the [docs].

The TwiML Redirect Studio widget allows you to redirect control of a voice or messaging execution away from Studio to execute custom TWiML and then return back to the flow. This allows you to extend Studio further with your own custom code.

To learn more, visit the documentation on the TwiML redirect widget, or try it out in Studio.

The new version of Marketing Campaigns now supports contact storage for up to 10M contacts per user, with additional scale possible on a per-user request.
