ARDUINO 1.8.9 2019.03.15
[ide]
* New target! ARM64 boards are now fully supported (Nvidia Jetson and RaspberryPi3 with 64bit operating system)
* Fix UTF8 related bugs on Windows
* Fixed: can now compile again using OpenJDK (removed dependency on JavaFx)
* Fixed: only use touchBar on OSX 10.12 or higher
* PluggableDiscovery: easily add your own discoverer and make it available in Boards/Port menu (thanks @PaulStoffregen for the idea and the initial implementation)
* LibManager: reduce slowdown when searching
* Fixed: ensure a sketch line is visible when it contains an error and must be highlighted
* Linux: the installer now tries to install a symlink is /usr/local/bin (this doesn't affect usual non-systemwide installation) Thanks @2E0PGS
