Today’s Google Home release notes (October 29, 2026) detail what’s new in firmware updates for Chromecast with Google TV and Nest Wifi Pro.
The first update of 2026 for Chromecast with Google TV (4K) rolled out earlier this month. At the time, Google’s changelog only mentioned the August 2026 Android security patch level and “Other bug fixes and performance improvements.”
This changelog adds “Improvements to connectivity, media streaming, and display performance.”
- Android security patch level upgrade until August 2026
- Improvements to connectivity, media streaming, and display performance
- General bug fixes and system stability improvements
Google also noted today that the Chromecast with Google TV (HD) is receiving this update, but the new firmware version has not yet been released.
Meanwhile, the Nest Wifi Pro sees three updates:
- Networking: Enabled automatic failover to ISP DNS when public DNS is blocked. Improved reliability of node configuration.
- Platform and wireless: Optimization of the performance of the RSSI mesh and client management, and improvement of the stability of wpa_supplicant and DHCP clients.
- Ecosystem and security: Updated Google Home Platform and applied comprehensive security improvements.
The updated firmware does not appear to have been rolled out yet, as the version listed and on the device remains 3.78.518349 from February/March 2026.
Google also details what’s new in this month’s Nest Wifi (2019) update that we spotted previously:
