@Eng-Abdullah-Ghazi-AlMusalami This is our 1.14 branch: https://github.com/modalai/px4-firmware/tree/voxl-dev. We have been flying with it for quite some time now but it is not complete and ready for general release. Major features still missing are Qualcomm Flight RB5 5G Platform VIO support, collision avoidance, and M0065 support. The documentation is still being prepared. If you are comfortable getting started without those things then feel free to start playing around with it. Otherwise I would recommend waiting for our official release of it. It's about 4 weeks out at this point.
