v1.7.3 Beta Release

This release is based on the new CI system and configuration and addresses a number of usability issues on vehicle setup:

• Cascaded EKF2 error messages so they do not trigger when calibration is missing on the sensors
• Disabled some text / speech outputs when disarmed
• Ensured manual override is always enabled in fixed wing

v1.7.2 Stable Release

Fixes boot issues with some boards that deviate from the reference design.

v1.7.0 Stable Release

Release Notes

• First-generation experimental support for ROS2-like setups with FastRTPS
• Support for many new sensors (LIDAR, airspeed, IMU, etc)
• Significant robustness improvements and new features in default estimation system (EKF2)
• Significant improvements to VTOL flight control
• Increased smoothness of multicopter flight control
• Better performance of fixed wing flight control
• Many build system improvements (including 50% faster nuttx builds)
• New continuous integration system system (http://ci.px4.io) with significantly more build and testing capacity
• Many improvements and fixes in various subsystems, as listed below.
• Reduced CPU load and RAM usage
