## **Security and Reliability Improvements**

* Fixed an issue in some boot cycles where redundant voltage readings used for ground station backup battery management could trigger a “Ground Station Battery Voltage is High” error during preflight checks when launching.
* Fixed a rare issue where the gimbal would stream video but not stabilize or receive commands from the tablet during takeoff and flight.
