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

v1.1.0 Release RC1

This release adds:

• CMake / Ninja build system
• Full UAVCAN support, including Firmware upgrades on the CAN nodes
• SITL for copters and VTOL
• Integration on the sensor level
• Separates the controller input state estimates from the true state estimates (which is important for the use of state estimates in areas where too much low passing / dampening of the output can lead to inaccuracies)
• Adds VTOL support for all flight modes
• Rattitude mode for FPV racing
• Assorted bug fixes and improvements

v1.0.1 Release

The v1.0.1 release adds an additional re-initialization routine to the fixed wing altitude controller ensuring it does not climb or loose altitude on the first switch to altitude control mode.

v1.0.0 Release

Initial release of the PX4 Flight Stack.

v1.0.0 Release RC3

This release includes the last missing changes:

• Full UAVCAN support for the current release
• Fixed an issue in TECS where a missing reset could lead to an initial increase or decrease in altitude before the current / desired altitude was held
• Fixed low memory issues on FMUv1. Now not only normal operation but also HIL are back operational

Second v1.0.0 beta release

The 2nd beta release addresses a few things addressed during testing:

• Fixed wing ALT / POS CTL: Fixed climb-out mode so that full pitch down doesn't resolve in a dive and full pitch up pulls up with max. throttle
