Twilio Changelog

Twilio Flex can now be used to develop compliant healthcare applications that contain protected health information (PHI) for organizations that are subject to the Health Insurance Portability and Accountability Act (HIPAA). Twilio will sign Business Associate Addendums (BAA) with covered entities and business associates for HIPAA Eligible Products and Services.

Lookup has introduced new mobile intelligence packages in its v2 API to help you power trusted interactions and build seamless onboarding experiences for your users. This includes:

• Line Type Intelligence, which returns the line type of a phone number, identifying everything from fixed VoIP and non-fixed VoIP numbers to landlines, toll-free and more. This is in Public Beta, supported worldwide and available self-service.
  
• SIM Swap, which detects recent changes between a mobile phone number and its associated SIM. This is in Private Beta, supported in key markets across Europe and North America.
• Call Forwarding, which returns the unconditional call forwarding status of a mobile phone number. This is in Private Beta and only supported in the UK.
• Lastly, the Lookup v2 API will also be supported by Twilio’s Ireland Region, which means you can call Lookup and ensure you remain data resident within the EU.

Read more about these features in our blog or check out our docs if you’re ready to start building.

When Twilio receives termination traffic to an inactive account, either due to the account being suspended or closed, Twilio will reply with a ‘603 Decline’ SIP Response. This will help trigger your infrastructure to failover to alternate trunks if your Twilio account is not active.

Included in the ‘603 Decline’ SIP response will be a X-Twilio-Error header referencing Error 10001: Account is not active. This will help your team to understand why your calls to Twilio are being declined so you can resolve the issue through adding funds if necessary or contacting Twilio Customer Support at help@twilio.com to inquire further.

See the docs for more information.

We are excited to release two new features to help you improve the resiliency of your Twilio Video workflows.

First, we have updated the congestion control used to measure available bandwidth for publisher and subscriber clients. The new congestion control will provide higher available bandwidth in extremely low bandwidth scenarios as well as faster bitrate recovery times in oscillating network conditions. This feature has been rolled out across all Twilio Video workflows and is automatically enabled on your Rooms.

Second, we released a new Media Warnings API. This API, which is only available for Javascript SDK users, will trigger a warning if you are recording a Participant but no media is being received by the media server. This alert enables you to know in advance if a recording track is going to be incomplete and empowers you to improve the situation by, for example, reconnecting the Participant. You can read more about the alert in our SDK changelog documentation.

The Segmentation v1 API will be deprecated on December 31, 2022. Following deprecation, all segments created in the Marketing Campaigns user interface will use the Segmentation v2 API.

Existing segments created with the Segmentation v1 API will remain editable through December 31, 2022 using either the Marketing Campaigns user interface or Segmentation v1 API.

After December 31, 2022, the following changes will be made:

• Twilio SendGrid will attempt to migrate all segments created with the Segmentation v1 API that are not used in an Automation or a scheduled Single Send to the Segmentation v2 API for you.
  • We may be unable to migrate some of the segments created using the v1 API, which will require you to manually migrate segments. See Upgrade a v1 Segment to v2 for instructions.
  • Twilio SendGrid will stop processing segments created using the v1 API that haven’t been migrated or cannot be migrated automatically, meaning no contacts will join or leave the segments. We will not delete segments created using the v1 API, and you should not anticipate any data loss during this deprecation.
  • Unmigrated segments will count against your segment limit. For this reason, we recommend you migrate all your segments from v1 to v2 manually as soon as possible.
• POST and PATCH Segmentation v1 API endpoints used to create and update segments will no longer be accessible.
• GET and DELETE Segmentation v1 API endpoints will remain available so that customers can retrieve their data and manually migrate segments to the v2 API.

We are very excited to announce that Twilio's WhatsApp Sandbox number now works with the Conversations API! You can try it out yourself by following the new tutorial in our docs. We can't wait to see what you build!

We are excited to announce that Super SIM now has VPN support, enabling you to set up secure private networks between Twilio and your application data centers and have your Super SIM connected devices use these private networks.

With a VPN, you get the following benefits:

• Secure channel between Twilio and your application cloud with the traffic going through a VPN tunnel instead of the open Internet.
• Static Private IP address per SIM allowing you to initiate connections from your application cloud to your devices
• No NAT or Firewall timers for UDP and TCP sessions.

If your IoT application needs a Super SIM VPN, please reach out to your Twilio sales representative or Twilio Support to get access to the documentation and to set up a VPN connection for your IoT devices.

Effective July 1st, 2022, all Twilio SendGrid Essentials 40k and 100k packages have changed. The Essentials 40k package is now the Essentials 50k package with a new price, and the Essentials 100k package price has changed.

The new Essentials 50k package comes with 50,000 emails/month for $19.95/month, and $0.00133/email overage. The Essentials 100k package price has increased to $34.95/month, and $0.0009/email overage.

We are committed to continued investment in our infrastructure and innovation to provide the best-in-class features you need to build exceptional experiences with email. The features included in the Essentials plan and prices of add-ons are not changing at this time. You can review past invoices and update your Plan and Billing Details in the SendGrid application. If you have any questions please reach out to our knowledgeable support team.

We are excited to announce that we will be making some changes to the release stages of our Twilio Helper Libraries.

We are adding new Release Candidates (RC), which are a pre-release of a new major version of our helper libraries. RCs will follow the version pattern “X.0.0-rc.Y” where “X” is the current major version + 1 and “Y” is the Yth release of the RC. For example, the current version of the Twilio Java Helper Library is 8.30.0 and the first release of an RC for the next major version will be 9.0.0-rc.1.

Following the Release Candidate (RC), we will release a General Availability (GA) helper library version. This will be a new major version of a helper library, which will remove the pre-release identifier (e.g., 9.0.0). There are to be no expected breaking changes as part of the GA work, though there may be exceptions.

The Video Diagnostics App tests an end user’s ability to have a quality video call with Twilio Programmable Video. It runs through a series of tests to identify issues related to device and software setup, connectivity to the Twilio cloud, and network performance. Upon failed tests, it provides recommendations to help your users help themselves.

With this release, the Video Diagnostics app is now available for your use as
a Twilio-hosted web app. It can be used as part of your onboarding or support processes to assist in diagnosing end-user issues. This hosted version of the Video Diagnostics app supersedes the legacy network test tool (https://networktest.twilio.com/).

If you would rather customize the app and embed it into your application, the code is freely available as an open source ReactJS app and provides a reference for how to utilize Twilio’s RTC Diagnostics SDK and the Javascript Preflight API.
