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

First v1.0.0 beta release

UPGRADE TO LATEST QGROUNDCONTROL STABLE FOR CALIBRATING SENSORS

• Fixed wing improvements in altitude control and takeoff
• Improved magnetometer calibration
• General usability improvements

This release candidate is the first version suitable for wider beta testing.

Twelfth release candidate for v1.0.0 release

• System does not set a home position any more when already armed and gaining GPS lock
• Missions containing relative altitude waypoints are verboten when no home is set (the system will complain and loiter)
• Fixes for the manual trim capability in manual override mode
• Improvements in the FX79 mixer
• Yaw control retained in high trottle situations for multicopters (@Tumbili)
• HIL usability improvements (Mark Whitehorn)

Release candidate eleven for v1.0.0 release

• Fix multicopter full throttle yaw control issue
• Make L1 controller distance dependent on current velocity and L1 distance
• HIL fixes for fixed wing, improving HIL reliability greatly
• Improved default config for TBS Caipirinha
• New ALTCTL and POSCTL flight modes for fixed wing
• New STAB flight mode for multicopters
• ACRO switch used now to switch between MAN and STAB for planes and ACRO and STAB (man) for multicopters

Release candidate nine for v1.0.0 release

Release candidate with a number of improvements and bug fixes:

• Optional attitude_estimator_q from Anton Babushkin (@DrTon, lightweight, elegant, estimates gyro offsets)
• New mixer: Modifies collective throttle to keep system stable when motors saturate (by @Tumbili)
• Preflight checks: Prevent takeoff with unhealthy system configurations (by @Zefz)
• Logging: Default to 100 Hz on Pixhawk (user-configurable via parameter)
• MAVLink FTP: 30x speedup and bugfixes (by @DonLakeFlyer)
• Improvements for gyro, mag and accel calibration (more rigour but also more user assistance)
• MPU6K, LSM303D and L3GD20(H): Reject duplicate measurements (by @tridge Andrew Tridgell)
• Better boot error reporting (by @sjwilks)
• Fix airspeed handling in ECL fixed wing controller (by @thomasgubler)
• Firefly Y6 support (by @Tumbili)
• Only transmit used parameters feature + fixes, speeds up param transfers (by @davids5)
• Fixes for state-level HIL
• Fixes for offboard control with velocity commands
• Param meta data by @DonLakeFlyer
• STM32F4Discovery support (by @nopeppermint)
• Various mavlink fixes (by @NaterGator)

Release candidate ten for v1.0.0 release

• Fix a param indexing issue which made param retransmission over radio links unstable.
