v1.3.0 Release RC3

This fixes a wrong lowpass filter constant for battery charge level estimation. This version is also currently available on the beta branch and can be flashed by selecting the advanced options in the flash dialog and then beta.

Correct QGC version: https://github.com/mavlink/qgroundcontrol/releases/tag/v2.9.5

v1.3.0 Release RC2

v1.3.0rc2

Fix battery charge level filter

1.3.0 Release RC1

v1.3.0rc1

First release candidate for 1.3.0 release

v1.2.0 Release

This release introduces substantial improvements of the VTOL control and autonomy code, the estimation & control library, an initial version of EKF2 and dozens of general fixes and improvements.

v1.1.3 Release

This release does add some new functionality for Pixracer, but mostly addresses issues found by users:

• RTL: If the copter was facing away from home it would first drift off until it yawed towards home before flying back to home properly
• Yaw handling on multicopter: The multicopter used a code path shared with VTOL and was in a suboptimal yaw control mode
• Fixed wing: Large mixer configs were not loading correctly and aborted boot. Although not safety critical, it was locking out some fixed wing users from the last release
• Pixracer: Enable FrSky telemetry and MAVLink OSD telemetry by default on the TELEM2 (OSD) and FrSky ports
• Pixracer: Remove a glitch during system boot on the PWM lines
• Lots of other smaller fixes and improvements

v1.1.2 Release

This release includes minor fixes:

• FMUv2: Start baro on correct bus. This is a regression of the Pixracer integration and could lead to aborted boots
• All board: Ensure that UAVCAN_ENABLE param is always loaded.

v1.1.1 Release

This release defaults MAVLink to on via USB and only offers the NSH shell via USB when the microSD card is not plugged into the autopilot.

A second huge addition is the support for log downloads through the specialised log protocol and QGroundControl (USB on any flight controller and Wifi on Pixracer are supported).

It also includes various smaller improvements and bugfixes for all airframes and boards.

v1.1.0 Release

• Switch to CMake build system
• Significant improvements in the user model / interaction (requires QGroundControl v2.8.0 or newer, using a daily build is recommended)
• Full VTOL support for all three major VTOL design types enabled (Tailsitters, tiltrotors, plane + quad combination, all flight modes, still under heavy development)
• Rattitude mode for FPV racers: Combination of attitude and rate control
• Better altitude hold (significant improvements, but more improvements pending)
• Support for coaxial helicopters
• Full native SITL on Mac OS and Linux: http://dev.px4.io/simulation-sitl.html
• Snapdragon Flight support (there is a next-generation version currently being worked on)
• Autonomous takeoff and landing on runways for planes
• Full support for UAVCAN, including UAVCAN-enabled motor controllers and automatic Firmware upgrades via UAVCAN (if you connect an ESC to the system, it will always be auto-upgraded)
• New board architecture: FMUv4, with the Pixracer being the first board of the new generation: http://dev.px4.io/hardware-pixracer.html

v1.1.0 Release RC3

This is the third v1.1.0 beta release with zero open issues for the release. This is purely for validation and will become the release unless major issues are discovered.

v1.1.0 Release RC2

This RC2 fixes a boot issue with VTOL configurations and contains a number of other fixes and improvements
