  • Significantly improved performance on racing drones (users need to reconfigure, link)
    • Improved filtering and reduced control latency
    • Added Airmode
  • Improved flight performance on VTOL (Tiltrotors, Tailsitters)
  • Support for building natively on Windows (link)
  • Significant EKF2 improvements
    • Hardening of the estimator for situations where GPS accuracy is limited

PX4 v1.7.3 Release January 2018

This is a maintenance release for v1.7

  • Fixed board support for boards electrically departing from FMUv2 schematic from several manufacturers
  • 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
  • Help developers to use the correct config for their board if there are multiple compatibles ones
  • Reduce CPU load of VTOL controller

  • 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 ( with significantly more build and testing capacity
  • Many improvements and fixes in various subsystems, as listed below.
  • Reduced CPU load and RAM usage

PX4 v1.6.5 Release July 2017
