DesktopAndroid APKDevicesWeb14/10/2026 : Browser and videoIn development

All Platforms

  • Change Search : DuckDuckGo becomes the default search engine. Explicit engine choices are preserved.

Desktop

  • Test Browser : DuckDuckGo navigation and return to Home checked in the test profile.

Android / APK

  • Note Installation : Shared resources updated; no new APK distributed for these fixes.

Sargo / Pixel 3a
