End of Life (EOL) for Outdated Sync and Chat SDK Versions

Twilio is announcing the end of life (EOL) for outdated versions of the Sync and Chat SDKs. Starting on March 31, 2025, the following SDK versions will no longer be supported, and critical features such as live updates and chat functionality will stop working:

Sync SDK:

  • Javaccript: Versions below 0.8.1

  • iOS: Versions below 0.8.1

  • Android: Versions below 0.8.0

Chat SDK:

  • Javascript: Versions below 3.0.0

  • iOS: Versions below 2.4.2

  • Android: Versions below 4.0.0

SDKs that are not updated by the EOL date may fail to connect to Twilio services and could return errors such as 404 “HOST_NOT_FOUND.”

This change allows Twilio to focus on delivering faster troubleshooting, better guidance when issues arise, enhanced security, and improved performance for applications using supported SDK versions. Upgrading ensures your applications benefit from these improvements and remain operational.
