Twilio Changelog

As of September 11, 2025, Twilio Voice, Video, and Conversations will no longer support TLS v1.0 and v1.1 for the following endpoint:

sdk.twilio.com (used to host assets and SDK documentation related to Voice, Video, and Conversations)

Any connection attempts made after this date will fail. Due to TLS security vulnerabilities, we will stop offering TLS 1.0 or 1.1 protocols on this date; only the TLS 1.2 protocol will be supported.

Between Monday, November 24, 2025 and Monday, January 5, 2026, Twilio will enter a Heightened Awareness Period (HAP) to help ensure reliable message delivery during peak traffic times, such as Black Friday and Cyber Monday. 

During this period, message sending rates to U.S. destinations will be monitored and may be limited at the account level for toll-free, short code, and 10DLC numbers.

Accounts that send high volumes of messages from short codes or toll-free numbers may be temporarily migrated to Market Throughput during the HAP; customers will be notified via email if their account is affected. Market Throughput does not affect 10DLC numbers, which will continue to live on Account Based Throughput.

As of September 10, 2025, Twilio Flex no longer supports TLS v1.0 or v1.1 for the assets.flex.twilio.com endpoint, which hosts assets and SDK documentation related to Flex UI. If you try to connect to this endpoint using TLS v1.0 or v1.1, your request will fail. To make sure your request uses a supported protocol, use TLS v1.2 or later.

We’re excited to announce that Flex UI 2.14.0 is now available. This release includes:

• Email support for text alignment and right-to-left languages.

• On the Teams View page, new custom columns in the filter panel.

Throughout Flex UI, you'll find feature and UI enhancements, bug fixes, and more. 

For complete details, see the Flex UI release notes for 2.14.0.

We're excited to announce that we will be gradually rolling out a new version of the Messaging Insights UI starting today. New UI is designed for improved performance. 

Important action required after the roll out is complete for your users: Any previously saved filters and bookmarks will not carry over to the new interface. Please reapply your filters and update your bookmarks. To prevent confusion, consider deleting any old Insights bookmarks that no longer function with the updated UI.

As of September 5, 2025 the Legacy Boku Identity APIs Infrastructure in Indonesia will be migrated.

We would like to inform you about upcoming changes to Legacy Boku Identity API’s production infrastructure in Indonesia. These changes will not impact your current service. Our goal is to minimize impact to your current integration to our services. These updates are part of our ongoing commitment to improving performance, scalability, and reliability for all our customers.

If you have whitelisted or hardcorded our IP addresses instead of URLs, please make a note of our new IP addresses. These new IP addresses will take effect once we perform the switchover to AWS cloud services.

Our support team is available to assist you with any questions or concerns at accsec-onboarding@twilio.com.

Thank you for choosing Twilio. We appreciate your partnership and look forward to continuing to provide you with exceptional service.

Meta has changed what is allowed in button text within WhatsApp authentication templates. Only hardcoded, localized language translations of "Copy code" are now allowed and capitalization rules are now enforced.

No changes are needed from Twilio customers to creating or sending authentication templates.
