* Upgraded parameters of Unreal/CarlaUE4/Config/DefaultInput.ini to prevent mouse freeze
* Add build variant with AD RSS library integration with RSS sensor and result visualisation
* Support for OpenGL and Vulkan in docker + headless mode
* Added new sensor: Inertial measurement unit (IMU)
* Added new sensor: Radar
* Exposed rgb camera attributes: exposure, depth of field, tonemapper, color correction, and chromatic aberration
* Now all the camera-based sensors are provided with an additional parametrized lens distortion shader
* Added TrafficManager to replace autopilot in managing the NPC vehicles
* Improved pedestrians navigation
* API changes:
- Lidar: `range` is now set in meters, not in centimeters
- Lidar: `horizontal_angle` is now received in radians, not in degrees
- GNSS: `carla.GnssEvent` renamed to `carla.GnssMeasurement`
* API extensions:
- Added `carla.IMUMeasurement`
- Added `carla.RadarMeasurement` and `carla.RadarDetection`
- GNSS data can now be obtained with noise
- IMU data can now be obtained with noise
* Moved GNSS sensor from client to server side
* Added exporter plugin for UE4 to allow export meshes ready for Recast calculation
* The 'make import' process now rename the assets accordingly and set complex collision as simple
* New Python API function added (map.get_crosswalks()) that returns a list with all points that define the crosswalk zones from OpenDRIVE file
* Updated `manual_control.py` with a lens disortion effect example
* Updated `manual_control.py` with IMU and Radar realtime visualization
* Fixed pylint for python3 in travis
* Fixed PointCloudIO `cout` that interfiered with other python modules
* Better steering in manual control
* Added Doxygen documentation online with automatic updates through Jenkins pipeline
* Fixed an error in `automatic_control.py` failing because the `Num Lock` key
* Fixed client_bounding_boxes.py example script
* Fixed materials and semantic segmentation issues regarding importing assets
* Fixed ObstacleSensor to return HitDistance instead of HitRadius
