v1.16.0 - Stable Release

What's Changed

PX4 v1.16 builds on the momentum of v1.15 with significant new features and expanded hardware support thanks to our community contributions. This release introduces bidirectional DShot support sponsored by ARK, a full rover rework with dedicated firmware builds and modular control modes for Ackermann, differential and mecanum rovers, and a switch to Gazebo Harmonic LTS for more reliable simulation. Developers will benefit from the new ROS 2 Message Translation Node for dynamic message versioning and integrated log encryption that embeds decryption keys directly in logs.
We also added fresh sensor drivers and board support across our partner ecosystem alongside dozens of improvements in control, estimation and safety. PX4 v1.16 raises the bar for performance and usability. Upgrade today and let us know your feedback on GitHub.

Major Changes

• Bidirectional DShot - [Sponsored by ARK] (PX4-Autopilot#23863)
• Rover support rework
  • New dedicated firmware build for rovers (airframe IDs 50000–52000)
  • Separate modules for Ackermann, differential and mecanum rovers, each with manual, acro, stabilized, position and auto modes
  • Shared pure-pursuit guidance library for all rover modules
  • Legacy rover position control module deprecated in favor of the new modules
• Gazebo Harmonic LTS release replaces Gazebo Garden as the version supported by PX4.
• ROS 2 Message Translation Node to translate PX4 messages from one definition version to another dynamically. (PX4-Autopilot#24113)
• Log Encryption now generates an encrypted log that contains the public-key-encrypted symmetric key that can be used to decrypt it, instead of putting the key into a separate file.
