Go 语言是谷歌 2009 发布的第二款开源编程语言。Go 语言专门针对多处理器系统应用程序的编程进行了优化，使用 Go 编译的程序可以媲美C或 C++ 代码的速度，而且更加安全、支持并行进程。而今天 ，Go 1 发布里程碑式的 release 版本！

Go 1 现在已经是 Google App Engine 上的标准的 Go 运行环境了。
Go version 1 is released
Today marks a major milestone in the development of the Go programming language. We're announcing Go version 1, or Go 1 for short, which defines a language and a set of core libraries to provide a stable foundation for creating reliable products, projects, and publications.Go 1 is the first release of Go that is available in supported binary distributions. They are available for Linux， FreeBSD, Mac OS X and, we are thrilled to announce, Windows.
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, _disibledevent=>Go 1 compatibility document explains the compatibility guidelines in more detail.
Go 1 is a representation of Go as it is used today， not a major redesign. In its planning, we focused _disibledevent=>go fix tool can automate much of the work needed to bring programs up to the Go 1 standard.
Go 1 introduces changes to the language (such as new types for Unicode characters anderrors) and the standard library (such as the new time package and renamings in the strconv package). Also, the package hierarchy has been rearranged to group related items together, such as moving the networking facilities, for instance the rpc package, into subdirectories of net. A complete list of changes is documented in the Go 1 release notes. That document is an essential reference for programmers migrating code from earlier versions of Go.
We also restructured the Go tool suite around the new go command, a program for fetching, building, installing and maintaining Go code. The go command eliminates the need for Makefiles to write Go code because it uses the Go program source itself to derive the build instructions. No more build scripts!
Finally， the release of Go 1 triggers a new release of the Google App Engine SDK. A similar process of revision and stabilization has been applied to the App Engine libraries, providing a base for developers to build programs for App Engine that will run for years.
Go 1 is the result of a major effort by the core Go team and our many contributors from the open source community. We thank everyone who helped make this happen.
There has never been a better time to be a Go programmer. Everything you need to get started is at golang.org.
