Twilio Changelog

The new version of Marketing Campaigns now supports sending a Single Send to a segment based on engagement data for more personalized sending. This includes whether they have or haven’t opened or clicked within a given timeframe as well as how they’ve engaged with a particular Single Send.

The new version of Marketing Campaigns now offers a Segmentation API to create and send to a segment that is based on engagement (opens/clicks) with any Single Send or a specific Single Send.

With this release, you are able to set the bitrate your Voice Client JS application should use. This allows you to better plan and estimate your bandwidth requirements.

Effective September 10, for new phone numbers provisioned through the existing Phone Number Provisioning API, address requirements will be enforced via the API, provided through an AddressSid. This means you will be required to provide addresses for newly provisioned regulated phone numbers. API calls to provisioned phone numbers that do not submit a valid address will fail with error code 21631. Only API calls provisioning numbers outside the US and Canada that fail to send an address are affected.

Voice iOS SDK 2.1 adds support for the new VoIP push notification requirements introduced in iOS 13 & Xcode 11. If you build your App with Xcode 11, you must upgrade to this version to avoid service disruption to your iOS 13 users.

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.
