Legacy Twilio Programmable Voice and Video SDKs impacted by SSL certificate deprecation

Legacy versions of some Twilio Programmable Voice and Video SDKs that you may be using in your applications may be impacted by an upcoming change to Twilio's SSL certificates. Please read on to determine whether your application is impacted and recommended steps to ensure your users are not affected.

What is Happening?

As part of an industry-wide effort, Twilio and many other vendors including Google have made plans to gradually distrust and remove dependencies on Thawte certificates. Twilio is in the process of replacing its Thawte SSL certificates with new certificates from a different provider.

Some older versions of Twilio's SDKs only trust certificates from Thawte. When we replace the current certificates, these older SDK releases will refuse to accept the new certificate, and will refuse to connect to Twilio. Newer versions of our SDKs are able to accept certificates from multiple providers and will continue to work without interruption.

When is this happening?

The affected versions of Programmable Voice and Video SDKs for iOS and Android will cease functioning on September 13, 2018 at 4 pm Pacific Time. For continuity of service, it is imperative that you update your apps to use the latest Twilio SDKs and release them to the App/Play store before that time. We encourage you to do so as soon as possible.
