This release changes the estimator to EKF2 for all vehicles as it is the most tested in typical outdoor scenarios. Indoor scenarios and general R&D applications continue to benefit greatly from the LPE estimator.

To switch back to the previous default, set SYS_MC_EST_GROUP to 1. To use EKF2, set SYS_MC_EST_GROUP to 2.

Most notable changes / improvements:

  • EKF2 default estimator
  • STM32F7 support added
  • Crazyflie support added
  • Parrot Bebop 2 support added
  • Log streaming via Wifi to the ground and straight to the cloud
  • New log analysis tool with real-time zoomable plots (logs.px4.io)
