Twilio Changelog

To accommodate growth in traffic, we have expanded our Media IP address ranges in our AU1, BR1, DE1, JP1, and SG1 data centers for the following products:

• Elastic SIP Trunking
• Programmable Voice SIP Interfaces
• Programmable Voice Mobile SDKs
• Twilio Client JS SDK

If you currently allow any of our Media IP addresses in your IP communications infrastructure, you MUST add the new IP address ranges to your allow list.

For a complete list of IP address ranges to allow in your IP communications customer infrastructure, please see:

• Elastic SIP Trunking
• Programmable Voice SIP Interface
• Programmable Voice Mobile SDKs and/or Twilio Client JS SDK

Twilio Debugger in Console has been enhanced to now show more errors and warnings that may have occurred in your Twilio application. Previously, the Debugger only displayed the 50 most recent items, making it difficult to track down problems that occurred in the past. With this change, you and your development team can more easily debug older items, track historical trends, and find regressions from previous weeks.

This is available to all customers today by visiting the Debugger in the Twilio Console.

You can now enable and disable Voice Trace directly in the Voice Settings section of Console. Voice Trace allows Twilio's support team to investigate issues with call quality by capturing the RTP payload in pcaps for analysis. For more information on Voice Trace see the Glossary.

Twilio Monitor API, our API for programmatically accessing errors and warnings from the Twilio Debugger, now supports alerts from 7 more products. This makes it easier to gain more insights into how your Twilio applications are performing and how to resolve issues quickly. The additional Twilio products that now have alerts published to Monitor API include Autopilot, Fax, Flex, Functions, Programmable Video, Proxy, and Studio. These additional errors and warnings appear automatically in the Console Debugger, Monitor API, Debugger webhooks, and Alert Triggers.

The new version of Marketing Campaigns now features a Design Library, a new, top-level navigation item in the navigation on the left that houses all Email Designs for use within Marketing Campaigns. “Templates” remains as an option under the Marketing [New] navigation, and, if clicked, it will bring customers to the Design Library.

We have updated all Flex projects that use Automatic Updates to Flex UI 1.13.

This Flex UI release introduces new notifications for call transfer failures, minor fixes to how we handle custom chat tasks, and UI performance improvements.

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 supports IP Pool Selection for users who have created IP Pools. This allows senders to choose which IP Pool to send a Single Send or Automation from, providing improved control over reputation and deliverability.

You can now configure Flex Flows message handling within the Twilio Console with two new behaviors:

• Direct to TaskRouter
• External Webhook

You can use these behaviors to setup outbound messaging use cases or to handle your messages outside of Studio. Learn more about managing your messaging configuration in our Flex Messaging Developer Guides.

Strong Customer Authentication (SCA), a new rule that came into effect on September 14, 2019, as part of PSD2 regulation in Europe, requires changes to how European businesses authenticate online payments. You can read more here: https://stripe.com/docs/strong-customer-authentication

As a result of this directive, we have made a change to tag all payments captured using <Pay> with Stripe or CardConnect connector as MOTO (Mail Order/Telephone Order) payments, MOTO payments are exempt from PSD2 regulation. This change does not affect how Twilio <Pay> is used or the responses it generates upon successful payment. Moreover, this change does not apply when Twilio <Pay> is used to tokenize payment card information.

The new version of Marketing Campaigns now supports sending a test email to as many as ten email addresses. A test email can be sent for a Single Send, an email within an Automation, or an email design, and allows users to preview email content prior to sending or request review from partners outside of the UI.
