PX4 v1.16 reimagines rover support with dedicated firmware for Ackermann, differential, and mecanum drive types, all built on the same pure-pursuit guidance library for smooth, reliable path following. Simulation gets a major stability boost with the move to Gazebo Harmonic LTS, and flight controllers can now take advantage of bidirectional DShot for real-time motor feedback. Developers will benefit from the new ROS 2 Message Translation Node for handling message versioning on the fly, as well as built-in log encryption that stores keys alongside the log file for better security. Add in new sensor drivers, expanded hardware support, and improvements across control, estimation, and safety systems, and you have a release that delivers both big features and solid polish. Thanks to every contributor, tester, and community member who made v1.16 possible.
