I see that a unified Arduino IDE was recently released:
It is claimed that it works with every Arduino boards but there is no specific reference to the DUE.
Arduino IDE 1.8.0 works out of the box with AVR boards, like the Uno, Mega, Yun, and Micro, among the most popular. Additionally, it supports the Leonardo Ethernet, Yun Mini, Industrial 101, and Uno WiFi.
The updated SAMD core will provide support for the M0 and M0 PRO, completing the product line that includes the Zero, MKR1000, and the newly-launched Primo and MKRZero.
Does the new IDE support the DUE? If yes has anybody tested it with the DUE?
