Twilio Changelog

Voice Insights Events and Metrics are now available via API allowing near-real time access to call quality data for all call types.

Voice Insights Events include call progress events like ringing and completed for carrier and SIP calls, and quality events like network quality warnings and audio level alerts for Voice SDK calls.

Voice Insights Metrics provide a time series view of key performance indicators like jitter and packet loss to help identify the precise timing and severity of quality issues on calls.

Voice Insights Events and Metrics API access is included as part of Voice Insights Advanced Features which can be enabled in Voice Insights Settings.

Voice Insights has updated the jitter and packet loss thresholds for Voice SDK calls to reduce the number of false positives and improve the diagnostic capability of Voice Insights data.

Previously tags were applied to Voice SDK calls in response to network and audio warning events fired by the SDK. We have updated the tagging scheme for these calls to use the same thresholds as our gateway metrics for jitter and packet loss, and to use the cumulative metrics for the entire call instead of samples.

As a result of these changes consumers of the Voice Insights Call Summary API should expect to see a significant reduction in the number of calls tagged with SDK edge tags.

Note: the SDK events will continue to fire at the previously defined thresholds, and the events will continue to be sent to Voice Insights Event stream. This allows application developers to continue to provide the same level of proactive notification and prescriptive instruction in their applications to ensure optimal call quality.

Twilio Video Javascript SDK 2.0 is now GA! Thank you to all our beta users and for all the feedback you sent us during the beta period.

Twilio Video Javascript SDK 2.0 introduces the Track Priority API, Network Bandwidth Profile API, Reconnection States and Events, and the Region Selection API.

Track Priority and Network Bandwidth Profile API gives developers the ability to specify how bandwidth should be allocated between video tracks. Furthermore, the three profiles, (“grid”, “collaboration”, and “presentation”), specify when tracks should be switched off (or not) to conserve bandwidth for the highest priority tracks.

The Reconnection States and Events will automatically attempt to reconnect when a transient network error is encountered.

With Region Selection API, the SDK will automatically connect to the lowest latency data center. This API can also be configured to connect to a specific data center for cases where compliance might be required.

If migrating from a 1.x version, please refer to our migration guide.

The most common way to access Twilio REST API is by using your primary Account SID and token. However, you may want to implement a separate access policy for different developers or subparts of your application by utilizing API Keys instead. This allows you to revoke access easily and at the right granularity.

Now, you are able to use the very same API Keys method for authenticating with Media Content Service (mcs.us1.twilio.com) to upload any attachments you would like to be sent over Programmable Chat.

Read more about API Keys support in the documentation.

The path of the executing Function is now available in the context object at runtime, allowing you to reconstruct the full Function URL for use in your application.

We’ve added a brand new Designs API, allowing you to easily create, edit, download, or delete Email Designs without relying on the SendGrid app UI. You can use the Designs you’ve created across all of your Twilio SendGrid Email—from Automations, to Single Sends, and Dynamic Templates. For more about working with the API, see our API Reference.

Collect's Confirm feature simplifies programming your bot to confirm the answers it receives from the user during a question answer sequence. Confirm can be enabled separately on each question using the confirm attribute. Learn more about using Collect Confirm in the docs.

Inbound Context lets you add data to the Autopilot Memory before starting a dialogue with the bot. It can help you make the bot experience more personalized and contextual by making information like names, purchase histories, account numbers etc. stored in third-party systems available directly in the bot conversation.

Inbound Context is available on all channels supported by Autopilot:

• SMS
• Voice
• Studio
• Chat
• WhatsApp
• Facebook Messenger
• Alexa
• Google Assistant
• Custom Channel

Test your email content against spam filters, validate hyperlinks, and preview HTML rendering across browsers and devices with Email Testing for Dynamic Templates. Monthly testing credits included for Trial, Pro and Premier plans, with additional credits available for purchase. See our Email Testing documentation for more details.

We've made some improvements to Transactional Templates. We've renamed them to Dynamic Templates since they can be used to build the content for any type of email message sent over our Email API. They can be found in the app’s sidebar navigation under both the new “Email API” navigation item or the “Templates” navigation item. We've also eased ongoing template management by adding thumbnail images and allowing duplication of entire templates as well as the individual versions within a template.

For more, see our blog post about working with Dynamic Templates.
