Arduino

The open-source Arduino environment makes it easy to write code and upload it to the I/O board. It runs on Windows, OS X, and Linux. The environment is written in Java and based on Processing, avr-gcc, and other open-source software.

[ide]:

• IDE Toolbar can now go full width on 4K display.
• Environment variable LIBRARY_INDEX_URL is now correctly parsed (LIBRARY_INDEX_URL_GZ can also be optinally specified). Thanks @xardael
• Added per-board generic option in config file boards.txt for disabling control of dtr+rts. Thanks @d-a-v
• CLI: fixed missing "runtime.platform.path" when running without the `--board` option
• Linux: fixed desktop icon not launching the IDE in certain Window Managers (thanks @herrold)
• Allow setting low values for console size (correctly applies console.lines=x in preferences.txt)
• Make Preference window fit 600px height displays
• Fix error when renaming an unsaved, newly added file. Thanks @matthijskooijman
• Added the ability to increase/decrease font size via keyboard + mouse shortcuts (Ctrl + MouseWheel)
• Sketch names starting with a digit are now allowed
• Serial monitor is opened on a default position if the multi-monitor setup change (this should fix cases
• when the serial monitor is opened outside of the visibile space)

[libraries]:

• Fixed wrong folder name for "Adafruit Circuit Playground" library, now it can be updated cleanly.
• Fixed wrong include for "RobotIRRemote", now it should not interfere anymore with the real IRRemote
