Attention

If you are updateing from 2.8.1 or earlier, be aware that the new face engine is not compatible with old custom charpacks. The charpacks installed on the robot will automatically be removed in order for the new face enginge to run without problems. By updating, your custom charpacks will be removed and cannot be restored.

2.8.4 (Released 2025-07-23)

• Gaze Tracking Improvements: Enhanced vertical gaze tracking accuracy by removing redundant angle corrections that were causing over-calculation.
• Research Robot Support: All robots now function as research robots with expanded capabilities for External Feeds.
• Web Interface Enhancements:
  • AI Creator is now accessible to all users.
  • Added loading indicators for skills with separate GUIs (like AI Creator) for better user experience and naivgation.
  • Added network connection disclaimer warning users about IP changes when switching networks on the Robot.
• Network Management Improvements: Significantly enhanced WiFi connectivity with robust handling of special characters and spaces in SSIDs and passwords.
• SDK Launcher Updates:
  • Fixed user API key storage location to prevent repeated entry requirements.
  • Improved credential retrieval logic for ElevenLabs and other services.
• Character Pack Cleanup: Upgrade script now automatically removes conflicting legacy character pack folders to ensure compatibility with FaceCore.

2.8.3 (Released 2025-05-16)

• Camera Stream Enhancement: Exposed camera stream for Research Robots to all devices on the same network, allowing any user to access the camera stream from research robots.
• Local Camera Stream Access: Camera stream is now available locally for Skills to access on all robot types. Note that camera stream must be enabled for external access from the web interface Settings.
• Visual Improvements: Oral cavity textures now appear smoother with no artifacts or pixelation.
• Facial Expression Fix: All characters now display a neutral face with properly positioned eyebrows, resolving the issue where characters appeared sad.
• IMPORTANT: Users must backup their previously installed character packs before updating to this version. Character pack imports are now deprecated—you will not be able to import character packs after updating. If you're currently working with character packs, do not upgrade until you're ready to recreate all characters using our new Face Editor.
• SDK Launcher Fix: Resolved an issue preventing users from launching Furhat AI Creator from the launcher.

2.8.2 (Released 2025-04-29)

• Improved Wi-Fi connectivity, making it more robust and reliable in varying environments.
• Skills can now access the camera on non-research robots.

Known Issues

• Custom Charpacks Preventing Face Loading: Uploading custom charpacks to the robot currently causes face assets to fail loading. Removing the charpacks resolves the issue. This will be addressed in the next release by disabling the use of custom charpacks. Custom faces should instead be created and managed via the Face Editor.
• Missing Tongue Texture: In some cases, the tongue texture fails to load correctly, resulting in the inside of the mouth appearing with only two shades of red. This visual issue will be fixed in the next release.
• SDK Launcher: Skill Launch Buttons Failure: The new buttons for launching skills in the SDK Launcher may not work reliably in the current version. We are fixing this in the next version.
• SDK Launcher Update Fails on Windows (Certification Error): Updating the SDK Launcher on Windows systems currently fails due to a certificate validation error. This issue will be resolved in an upcoming release once the certificate has been updated.
