### 4.0.0

* Added ROI option during manual flight.
* Windows: Move builds to 64 bit, Qt 5.12.5
* Plan: ROI button will switch to Cancel ROI at appropriate times
* Plan: When ROI is selected the flight path lines which are affected by the ROI will change color
* ADSB: Added support for connecting to SBS server. Adds support for ADSB data from USB SDR Dongle running 'dump1090 --net' for example.
* Toolbar: Scrollable left/right on small screens like phones
* Plan View: New create plan UI for initial plan creation
* New Corridor editing tools ui. Includes ability to trace polyline by clicking.
* New Polygon editing tools ui. Includes ability to trace polygon by clicking.
* More performant flight path display algorithm. Mobile builds no longer show limited path length.
* ArduPilot: Add Motor Test vehicle setup page

* Log Replay: Support changing speed of playback
* Basic object avoidance added to vehicles.
* Added ability to set a joystick button to be single action or repeated action while the button is held down.

* Automated the ingestion of localization from Crowdin
* Automated the generation of language resources into the application
* Added all languages that come from Crowdin, even if empty.
* Allow dynamic language changes
* Check and respect camera storage status
* QGC now requires Qt 5.11 or greater. The idea is to standardize on Qt 5.12 (LTS). Just waiting for a solution for Windows as Qt dropped support for 32-bit.
* New, QtQuick MAVLink Inspector. The basics are already there but it still needs the ability to filter compID.
* Fixed application storage location on iOS. It was trying to save things where it could not.
* Basic support for secondary, thermal imaging with video streaming. If a camera provides both visual spectrum and thermal imaging, you have the option of displaying both at the same time.
* Better handling of fonts for Korean and Chinese locales. QGC now has builtin fonts for Korean (where some unusable font was being used). I still need to know if Chinese will need its own font as well.

* Making the camera API available to all firmwares, not just PX4.
* ArduPilot: Support configurable mavlink stream rates. Available from Settings/Mavlink page.
* Major rewrite and bug fix pass through Structure Scan. Previous version had such bad problems that it can no longer be supported. Plans with Structure Scan will need to be recreated. New QGC will not load old Structure Scan plans.
