Twilio Changelog

Twilio SendGrid now supports the “Multiple Reply-To” feature. This allows senders to include more than one recipient email address to receive replies and/or bounce messages from the recipient of the email.

This feature is available in the SMTP and V3 email APIs. For more information about this feature, please visit the documentation.

Developers can now retrieve the Service SID and Environment SID more easily within their Function code. These SIDs are automatically included in the context object of the invocation and can be accessed with the keys context.SERVICE_SID or context.ENVIRONMENT_SID. This change does not apply to Functions(Classic). For a small number of customers already using a large number of environment variables within their code this functionality may be disabled, and these variables will return undefined. For more information, visit the documentation for this feature.

To go along with this change, Runtime Handler version 1.1.2 is now available, and logs an error to your console if you access context.SERVICE_SID or context.ENVIRONMENT_SID during local development. This version is backward compatible and is available on the Serverless API and the New UI Editor. This handler version is not compatible with Functions(Classic).

To use the new handler version, go to the Dependencies tab, update @twilio/runtime-handler to 1.1.2, and create a new deployment. This handler version requires the Twilio SDK version 3.50.0 or later.

You can find documentation for Runtime Handler and detailed instructions on how to use the Runtime Handler with the Serverless Toolkit in our docs.

Twilio Event Streams 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.

Learn more about how to build on Twilio for HIPAA compliance.

All eligible Twilio customers can now start registration for US A2P 10DLC, in the Twilio console or via API. Registering protects and can improve SMS and MMS traffic deliverability and throughput.

To see who should currently register for A2P 10DLC, please refer to this article. In general, customers who send more than 3,000 SMS to the US using Long Code numbers can immediately begin taking action. To start registration, click here or go to Twilio Trust Hub, and select "Go to A2P Messaging".

Today we are kicking off the private beta program for Twilio Live. This new channel gives developers the tools to build immersive experiences that can be directly embedded into their applications. With Twilio Live, developers have access to a low-latency, secure live streaming platform that allows speakers to reach millions while providing an intuitive end-to-end developer experience, including flexible server-side API primitives, and client SDKs for iOS, Android, and JavaScript.

With Twilio Live, developers have the building blocks to create all types of interactive live event applications such as marketing conferences, next-generation social podcasts, shopping experiences, concerts, fitness classes, education sessions, and more.

For additional information on this release, see our blog posthere.

We have introduced a solution that enables Microsoft Teams Direct Routing to gain PSTN access using the Oracle Communications SBC and Twilio Elastic SIP Trunking. This combination enables any organization using Microsoft Teams Direct Routing to connect to the PSTN via Twilio Elastic SIP Trunking. You can learn more about this solution in our blog and by referencing Twilio Elastic SIP Trunking Solution Blueprints.

We have updated the experience when searching for and buying numbers in Console. In addition to refreshing the overall look at feel, we've streamlined the filters available when searching and made updates to provide more helpful guidance when numbers are not available.

Twilio Voice 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 Voice Javascript SDK 2.0 represents a much-needed spring cleaning of legacy APIs, including:

• Removing deprecated methods
• Renaming classes and methods to be less ambiguous
• Implementing new features introduced in 1.x as defaults
• Completely moving to the new TwilioError class which is standardized between Voice SDKs and contains much more detailed information about errors
• Full changelog available here

Additionally, new features will only be added to the 2.0 project going forward (e.g. not backported to 1.x) so you’ll want to migrate to this new major version to take advantage.

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

We are excited to announce that the support for using version 16.13.1 of React and ReactDOM on Flex is now generally available.

This allows you to use more of React’s APIs, including React Hooks, when developing your Flex plugins. You can set the React version of your Flex application on the Developer Setup Page. You are no longer required to set the UNBUNDLED_REACT argument for all your Flex Plugins CLI commands.

Review our React documentation for more details and upgrade to the latest version of the Flex Plugins CLI to get started.
