Google Cast SDK preview available - October 3, 2025

[cast-sdk-announcements]

Hello Google Cast developers!

We're providing a preview of the next Cast Web Receiver SDK to allow developers to test their apps in advance of the production release.

Major changes:

• Default useShakaForHls to true, making Shaka the default for all playbacks. Apps can still opt out. See https://developers.google.com/cast/docs/web_receiver/shaka_migration
• Bump default Shaka Player version to v4.15.12
• Added metadata API getDeviceInformation() to CastReceiverContext

Developers can test the new Web Receiver SDK prior to release using the preview URL: https://www.gstatic.com/cast/sdk/libs/caf_receiver/preview/cast_receiver_framework.js. This preview will be available for at least 3 weeks.  See more on this in the guide: https://developers.google.com/cast/preview-url.

Thanks,

Joey, on behalf of the Google Cast SDK Team
