Twilio Changelog

Network and Audio Warnings

Network degradation warnings were previously only logged to Insights. With this release, a new Call.Listener callback method onCallQualityWarningsChanged(Call call, Set<CallQualityWarnings> currentWarnings, Set<CallQualityWarnings> previousWarnings) is invoked when the SDK detects those degradations. Use these to relay network conditions to the user in order to provide better user experience or for debugging purposes. See the callback method and CallQualityWarnings for more information.

Mean Opinion Score (MOS)

This release also adds the Mean Opinion Score (MOS) measurement to StatsReport. Use Call.getStats() during a call to retrieve the score. Since the MOS is calculated from network performance measurements, it can be used to indicate the current network condition to the user to provide better usability.

Edge Locations

This release includes support for the expansion of Twilio’s Global Infrastructure via Edge Locations which allows customers to control their connectivity into and out of Twilio’s platform. The Voice Android SDK uses these Edges to connect to Twilio’s infrastructure via the new property Voice.edge. This new property supersedes the now deprecated Voice.region. See the new Edge names and how they map to the old region names.

Network and Audio Warnings

Network degradation warnings were previously only logged to Insights. With this release, a new TVOCallDelegate method call:didReceiveQualityWarnings:previousWarnings: is also invoked when the SDK detects those degradations. Use these to relay network conditions to the user in order to provide better user experience or for debugging purposes. See the delegate method: and callQualityWarnings for more information.

Mean Opinion Score (MOS)

This release also adds the Mean Opinion Score (MOS) measurement to TVOStatsReport. Use [TVOCall getStatsWithBlock:] during a call to retrieve the score. Since the MOS is calculated from network performance measurements, it can be used to indicate the current network condition to the user to provide better usability.

Edge Locations

This release includes support for the expansion of Twilio’s Global Infrastructure via Edge Locations which allows customers to control their connectivity into and out of Twilio’s platform. The Voice iOS SDK uses these Edges to connect to Twilio’s infrastructure via the new property TwilioVoice.edge. This new property supersedes the now deprecated TwilioVoice.region. See the new Edge names and how they map to the old region names.

We have enhanced how Programmable Video client SDKs connect to the Video Signaling servers. All SDKs now perform a back-off and retry if they receive a busy signal from the server. Additional error codes have been added to help developers troubleshoot client connection issues. The time for the JavaScript client SDK to connect has been reduced by over 250 milliseconds for connections originating outside of the us1 Twilio Region.

These changes will reduce the connection failure rate and help developers to manage the end user experience if connection failures do occur. The SDK versions are as follows:

• Twilio Video Javascript 2.5.0
• Twilio Video iOS 3.3.0
• Twilio Video Android 5.7.0

To learn more, visit the SDK specific changelogs for the Javascript SDK, iOS SDK, and Android SDK.

Twilio Conference resource now includes two additional fields that describe the reason why the conference has ended. A Voice Conference can end for several reasons. It can end when all participants have left, when the moderator has left, or it may also end programmatically via an API request. It can sometimes be difficult to determine the reason why the Conference ended. The new fields reason_conference_ended and call_sid_ending_conference on the Conference resource will make it easier to troubleshoot why the conference ended either via API or console.

Click here to learn more about the different reasons a conference can end in our Conference Resource documentation.

Twilio Edge Locations

This release includes support for the expansion of Twilio’s Global Infrastructure via Edge Locations which allows connectivity control into and out of Twilio’s platform. The Voice Client JS SDK uses these Edges to connect to Twilio’s infrastructure via the new parameter Twilio.Device.Options.edge. This new parameter supersedes the now deprecated Twilio.Device.Options.region. See Twilio.Device.Options.edge API documentation for more information.

Example

const device = new Device(token, { edge: 'ashburn' });

Support for Edge Fallback (Beta)

Deployments designed to connect to multiple Twilio Edge locations can take advantage of the new fallback mechanism. To enable the edge fallback, specify an array of edge names via Twilio.Device.Options.edge. When enabled and a connection failure is encountered, the SDK will reattempt the connection to the next Edge location in the array. For more details about how the fallback works, see the Edge fallback documentation.

Example

const device = new Device(token, { edge: ['ashburn-ix', 'san-jose-ix', 'roaming' ] });

Twilio SendGrid now provides two security features that allow you to verify that email event data is being posted by Twilio SendGrid: a Signed Event Webhook and OAuth 2.0. These security features are independent of one another and can be used together.

Twilio SendGrid’s Signed Event Webhook uses the Elliptic Curve Digital Signature Algorithm to sign requests. The signature allows customers to verify that event data is being posted by Twilio SendGrid.

OAuth 2.0 for the Twilio SendGrid Event Webhook allows customers to verify that Twilio SendGrid is properly authorized by them to post to their URLs using the Client Credentials grant type.

To learn more about these new features in Beta, visit our documentation.

The email editors within Marketing Campaigns now support more options for formatting your images. You can crop, flip and rotate your images, add filters, or make adjustments like contrast or opacity all from within your email editing workflow. These editing options are also available within the Design Library under Your Images. Learn more.

Starting August 15, 2020 you will be able to view call and conference logs in Console--and retrieve the resources via GET to the /Calls, /Conferences, and /Participants endpoints--for thirteen months after the resource is created. This represents a significant change as these logs are currently stored indefinitely by Twilio and retrievable via Console and API.

Before this change goes into effect, we will provide a Bulk Export utility in Console. Bulk Export will generate S3 files containing one day of data per file and deliver the download link via webhook, email, or Console. Records older than thirteen months will only be able to be retrieved via Bulk Export.

If you view logs in Console there is no follow up action, but just be aware that calls and conferences will now only display logs for the previous 13 months.

If you perform log extraction via API on a rolling basis, it is important to verify that you are pulling the logs at a frequency that will remain unaffected by this change.

Starting October 14, 2020 you will be able to view message logs in Console--and retrieve the resources via GET to the /Messages endpoint--for thirteen months after the resource is created.
