Ready to get your Go on. Google Programming Language, or Go for short, just added a number 1 to its moniker, representing the first official release. Go 1 includes some bug fixes, but it's not a major redesign, though added support for the Windows opens the language up to a broader group of programmers - you'll also find distributions for Linux, FreeBSD and OS X. Google gives you its word that Go 1 programs "will continue to compile and run without change. on a time scale of years," so you can rest assured that your efforts will not be in vain. There's also a new version of the Google App Engine SDK, which utilizes none other than Go.
