- Issues with the Widevine plugin for playing secured premium content (DRM) have been resolved.
- A problem that caused video playback issues from Twitter or during WebRTC calls on Intel systems with Gen6 GPUs has been fixed.
- A bug that made menu items unreadable in the settings section when High Contrast Mode was enabled has been resolved.
