The long-awaited release brought small, but important changes in the “cleansing” of the IDE and language, and also added many additional features. Updates for IDE include new file extensions, toolbar icons and color scheme, as well as an indicator on compilation and download. Changes in language affected the Serial class, the addition of DHCP and DNS, Ethernet support, the new SoftwareSerial library, support for multiple files in the SD library, changes to the 1-Wire library and UDP class, etc. For details, please see the release notes . In the coming days, we will try to update the directory on Arduino 1.0.
This release is a product of many people (listed in the release). Thanks to everyone who helped us get to it!
