Twilio Changelog

Twilio Messaging MaxPrice API parameter will be deprecated starting June 3, 2024. 

Effective April 11, 2024, new certificates will be deployed for all our REST API endpoints (e.g., api.twilio.com), including all regional edge locations. Only the end-user certificate will be renewed, as well as the certificate serial number. The root and intermediate certificates will remain the same. Such updates are common practice and do not impact customers that are using Twilio's services unless you are pinning certificates or are managing them manually.

The certificate will be available on the testing domain ( https://tls-test.twilio.com ) on March 11, 2024.

We highly discourage customers from pinning certificates as it exposes them to potential security risks and can cause downtimes for their services. Twilio customers using pinned certificates have a high probability of failed API Requests. These customers are advised to add the new certificates by Apr 8, 2024. You can follow the information mentioned on the official documentation.

We are excited to announce an enhancement in the A2P 10DLC Brand registration process. In our ongoing efforts to streamline and improve the user experience, we now have standardized error codes for any failures or issues encountered during Brand registration. These error codes will be directly available through the errors attribute on the Brand. 

With this release, it’s important to note that brand_feedback and failure_reason will be deprecated in an upcoming release.  If you have used these attributes in your integrations, we strongly advise transitioning to the new errors attribute due to its pending deprecation and limited information. 

Check out the updated Brand registration Twilio docs for more information. or a detailed list of all error codes please visit Twilio Error and Warning Dictionary.  

SendGrid and Segment are rolling out an updated signup experience that will route new customers to a shared Twilio signup page. This will provision a new SendGrid or Segment account in which a user will share a single identity and user settings will be managed on Twilio. No action is required for customers at this time. 

This change allows all new signups across Twilio products to easily sign up for another product and have a seamless cross-product navigation experience.

Starting March 11, 2024 Twilio Console and services.twilio.com will no longer support TLS version 1.1 and older, and outdated cipher suites. This is part of an important security upgrade to our systems. Customers running older operating systems or legacy network software may need to upgrade their systems to be compatible with these changes.

The following cipher suites that will no longer be supported in Twilio Console:

• ECDHE-ECDSA-AES256-SHA
• ECDHE-RSA-AES128-SHA
• ECDHE-RSA-AES256-SHA
• AES256-SHA
• AES128-SHA

Cipher suites in services.twilio.com will not be changed

We are thrilled to announce the ability to edit and retry A2P 10DLC Campaign registrations in Twilio Console. With this update, failed campaign registrations can be edited and resubmitted directly from Console. Additionally, this release introduces new fields for campaign registrations to provide more comprehensive campaign details ensuring the registrations meet compliance standards.

For more information on how to edit and retry Campaign submissions and understand the new fields in campaign registrations, please visit our detailed guide at: Troubleshooting and Rectifying A2P Campaigns.

The status-callback event for Programmable Voice calls has been renamed in Event Streams to com.twilio.voice.status-callback. Customers will need to update their Event Streams subscriptions to continue receiving the events. 

Twilio Voice media IP migration for Interconnect customers has been completed.

We are extending an invitation to Twilio Messaging customers to experience advanced capabilities for monitoring their messaging traffic. Our new Intelligent Alerts product monitors for anomalies in outbound messaging traffic in real-time using predictive artificial intelligence. Alerts are categorized to help prioritize events based on their impact on your business. Customers can configure notifications and review prior alerts on the Twilio Console.
