[note] This update only requires updating the drone. The controller does not need to be updated. Release notes were updated for clarity. [/note]

This update addresses critical bugs affecting flight reliability, hardware compatibility, and system stability for the Cayley release. Key improvements include fixes for in-flight failures, hardware integration, and enhanced error handling to ensure safer and more robust operations.

SECURITY

Hardware-Based Media Encryption Update (YubiKey)

The system now supports YubiKey 5 devices for hardware-based media encryption, including units running older firmware. This allows you to use newer YubiKey models without additional configuration. 

• YubiKey 4 devices continue to be supported without changes

FIXES AND IMPROVEMENTS

• Flight Safety and Reliability Updates — Adds several improvements aimed at reducing the likelihood of inflight disruptions and emergency landings.
• Improved handling of transient planning issues — The drone no longer initiates an emergency landing due to brief invalid data during path planning. Instead, it continues operating and only lands if the issue persists.
• Improved sensor redundancy for flight stability — The system can now switch between onboard motion sensors (IMU) during flight if an issue is detected, improving overall stability and resilience.
