Product changelog and announcements

We’ve added the Preflight API to the Twilio Programmable Voice React Native SDK, bringing the same pre-call diagnostics available in the native iOS and Android SDKs to React Native apps. Preflight provides a pre-call assessment of network stability, bandwidth, latency, jitter, MOS scores, and packet loss. Use it to surface network warnings, prioritize mobile data, or block calls on unreliable networks, improving connection success and call quality.

Check out the docs for integrating Preflight into your Voice application. We can’t wait to see what you build!

Segment is changing how we process incoming data for profiles that exceed their configured identifier cardinality limits.

Previously, profiles that surpassed an identifier limit (for example, more than 5 emails per profile) were marked as frozen and all subsequent data for those profiles—including events and traits—was dropped.

Starting in October 2025, Segment will continue to drop identifiers for types that have already exceeded their configured limit, but will resume accepting event and trait data, as well as new identifiers that remain within their limit. This change helps ensure that profiles that were previously paused due to limit violations continue to stay up-to-date with new behavioral and trait data.

Impact:

• Audience sizes may increase or decrease depending on event or computed-trait membership criteria.

• Some profiles may enter or exit active journey steps following this update.
  

No action is required on your part. If you have questions about how this change may affect your audiences or data flows, please contact friends@segment.com for assistance.

WhatsApp typing indicators are now supported on Twilio. Create typing indicators to signal to WhatsApp users that a response is being prepared. This improves user experience by reducing perceived wait times. Use typing indicators for responses that might take longer than a few seconds to generate.

To learn more about typing indicators on WhatsApp and how to send them, see our docs here.

Twilio SendGrid now requires HTTPS for all new Event Webhook configurations. Existing HTTP webhooks must be updated to HTTPS by February 11, 2026 to continue receiving event data.

We have added support for automatically detecting the language spoken by the user or sent via a text token for ConversationRelay.

We have added support for SSML tags to ConversationRelay to provide the pronunciation of a word or an acronym, specify where pauses should be, or increase or decrease the speed of spoken text.

Compliance Toolkit now suppports U.S. state-specific quiet hours, automatically rescheduling non-essential messages sent during select time windows to help you stay compliant with specific state regulations.

This release covers select quiet hour restrictions in the following states: Alabama, Connecticut, Florida, Louisiana, Maryland, Mississippi, Oklahoma, Tennessee, Texas, and Washington.

Learn more and see how to enable it in our docs here.

We have added support of adding a TwiML App directly to a Conference via the Conferences Participants subresource.
