Arduino has officially released their long awaited "Unifying" IDE that brings both the .cc and .org variants of the company together into perfect harmony.  Version 1.8.0 of the Arduino IDE works out of the box with AVR boards, like the Uno, Mega, Yun, and Micro, among the most popular. Additionally, it supports the Arduino Leonardo Ethernet, Arduino Yun Mini,Arduino Industrial 101, and Uno WiFi. Furthermore, Arduino says that the "SAMD core and NRF52 core (coming out in the next few days) will provide support for the M0, M0 PRO,"  this will complete the product line that includes the Arduino Zero, Arduino MKR1000, and the newly-launched  Arduino Primo and Arduino MKRZero. Additionally, version 1.8.0 of the IDE will now be able to run on Linux from the command line without the use of the X11 display, making life much easier for those who like to run headless, and still program their Arduino boards.  We have not had a chance yet to try out the new IDE, but Charles says to expect a review video on it when he returns to the office from his holiday travels. Download the version 1.8.0 of the Arduino IDE from Arduino.org.

New IDE for all Arduino boards!

Following the announcement at this year’s World Maker Faire, we’re excited to announce the release of Arduino IDE 1.8.0—the new official desktop editor for all Arduino boards, both .org and .cc alike.
This should come as great news to the entire Arduino community, representing a key milestone in our journey moving forward. You will now be able to use the desktop IDE 1.8.0 when working with any Arduino board from .org or .cc family. 

You will be able to download the latest and greatest unified Arduino Software from here.

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 Arduino Leonardo Ethernet, Arduino Yun Mini,Arduino Industrial 101, and Uno WiFi.

The updated SAMD core and NRF52 core (coming out in the next few days) will provide support for the M0, M0 PRO, completing the product line that includes the Arduino Zero, Arduino MKR1000, and the newly-launched  Arduino Primo and Arduino MKRZero.

More tech notes: You can now run the IDE on Linux directly in command line, no longer requiring the X11 display. Also on the Arduino Builder paths with strange UTF8 chars are now correctly handled.

Release after release, the community continues to play an integral role in our development. Be sure to check the entire revision log for a complete list of changes and credits. 

As always, don’t forget to report any issues you may find, either on the Arduino Forum or by writing to [email protected] or [email protected]. Your help is very much appreciated. 
And while in the holiday giving spirit, please consider supporting the Arduino Software by contributing to its progress! 

A special thanks to all developers and management team for their efforts in making this big step forward.
