Go 1 is the first release supporting binary distributions, which are available in Linux, FreeBSD, Mac OS X, and Windows. The language also integrates with Google's App Engine cloud platform.
"The driving motivation for Go 1 is stability for its users. People who write Go 1 programs can be confident that those programs will continue to compile and run without change, in many environments, on a time scale of years. Similarly, authors who write books about Go 1 can be sure that their examples and explanations will be helpful to readers today and into the future," according to a post from Go team member Andrew Gerrand on the Go language blog.
