Twilio Changelog

We are excited to announce the JavaScript SDK release of Adaptive Simulcast, a new feature that improves client performance by dynamically switching off unused simulcast spatial layers.

When using adaptive simulcast, a publisher will only encode video layers up to the highest spatial layer being used by subscribers.

For example, a common presentation layout in video chat will have the active speaker’s video in a large format and the remaining participants as thumbnails. In this situation, adaptive simulcast will encode all spatial layers for the active speaker and only the smallest spatial layer for the thumbnail participants. As speakers change, the respective publishing participants will automatically have their spatial layers turned on / off based on what is being used by subscribers in the room.

Compared to standard simulcast, adaptive simulcast will provide significant CPU and bandwidth improvements for your publishing clients, and we recommend all users switch from standard simulcast to adaptive simulcast.

This feature is currently only available in the JavaScript SDK. Please read our simulcast documentation to learn how to use this new feature.

Usage Insights provides a convenient way to view your Super SIM usage over time as graphs and tables. This lets you monitor upward/downward trends in usage as well as anomalous spikes or dips in your Super SIM activity. You can specify different ways to slice-and-dice your data, You can filter by:

The Flex Plugins CLI now automatically deletes the package of a plugin when it is being archived. When a plugin is archived, it deletes the built packages of all the versions of the plugins stored in Twilio Assets and when a particular plugin version is archived, it will only remove the plugin package of that particular version. This feature is automatically available with the archive command of the Flex Plugins CLI. This feature also enables you to cleanup your plugins when you hit the plugin limits on your Flex application.

Upgrade your plugins to the latest version of the Flex Plugins CLI to leverage this feature.

We are excited to announce that Message Scheduling is in public beta!

You can now schedule a message over SMS, MMS and Whatsapp using the Programmable Messaging API. Today, when you make an API request to Twilio’s Programmable Messaging API, a message is sent out instantaneously. With this new feature, you can intentionally delay or schedule the time a message is sent out up to 7 days in the future. This means you no longer have to rely on internal cron jobs or scheduling services.

Check out our documentation and blog post to learn more and try scheduling a message.

When you submit brand details for A2P registration, you will be shown feedback if the information could not be verified by the registration vendor, TCR. Based on this feedback, you can now edit the brand information, as explained here with an example of TrustHub UI in the Twilio console. If you are using the ISV APIs, you also have the capability to edit such a brand using APIs as explained here.

For the majority of brands facing verification failures, Twilio will allow you to update your brand up to three times via self-service, after which you would be redirected to customer support for further help. For a minority of brands facing failures, you will be redirected to customer support right away, since the problem can not be resolved via self-service.

Twilio will bear the costs of updating your brand. You can read more about updating your brand details and brand registration best practices here.

You can now manipulate the To and From numbers within SIP INVITE messages through creating Manipulation Policies in the Console.

The expected format of phone numbers in SIP INVITE requests can sometimes differ between on-premise equipment providers and carriers. For example, some PBXs might send numbers in a format other than E.164, the format that Twilio requires. Using Manipulation Policies, you can edit the contents of To and From numbers within SIP INVITEs to comply with formatting requirements, change the callerId of a call, or meet other needs of your public infrastructure.

To learn more, check out our documentation or try it out in the Console now!

A new Calls resource property, CallToken, has been added to the Programmable Voice API. CallToken is an optional parameter that customers can use to forward their calls. A CallToken is generated when an incoming call is received on Twilio. The CallToken is only generated when customers' voice URLs use POST. Customers can now populate the CallToken parameter with the CallToken from the incoming call to forward their calls and maintain the same caller-id from the inbound call on the outbound call.

In the future in the United States, when SHAKEN/STIR DIV PASSporT is supported by carriers, end to end call authentication will be possible by using the CallToken.

The feature External Storage for Video Recordings is now available for all video customers. Customers can configure the Video Recordings service to push Recordings or Compositions directly to their AWS S3 Bucket without additional charges.

This Video Recordings feature allows builders to create a recording workflow that matches their specific use case and regulatory needs. For example, a customer in the Education space may decide to store the composed recordings of a virtual classroom into a custom S3 for data sovereignty preferences.

This feature was previously a part of Twilio Editions.

To learn more check out the blog post or visit the documentation on Storing Recordings or Compositions to AWS S3.
