+Tags: release
+Summary: Go 1.1 is faster, less picky about return statements, and adds method expressions.

+##
+
+It is our great pleasure to announce the release of Go 1.1.
+
+.image go1.1/gopherbiplane5.jpg
+
+In March last year we released Go 1.0, and since then we have released three
+minor "point releases".
+The point releases were made to fix only critical issues,
+so the Go 1.0.3 you use today is still, in essence,
+the Go 1.0 we released in March 2012.
+
+Go 1.1 includes many improvements over 1.0.
+
+The most significant improvements are performance-related.
+We have made optimizations in the compiler and linker,
+garbage collector, goroutine scheduler, map implementation,
+and parts of the standard library.
+It is likely that your Go code will run noticeably faster when built with Go 1.1.
+
+There are some minor changes to the language itself,
+two of which are worth singling out here:
+the [changes to return requirements](https://golang.org/doc/go1.1#return) will
+lead to more succinct and correct programs,
+and the introduction of [method values](https://golang.org/doc/go1.1#method_values) provides
+an expressive way to bind a method to its receiver as a function value.
+
+Concurrent programming is safer in Go 1.1 with the addition of a race
+detector for finding memory synchronization errors in your programs.
+We will discuss the race detector more in an upcoming article,
+but for now [the manual](https://golang.org/doc/articles/race_detector.html) is
+a great place to get started.
+
+The tools and standard library have been improved and expanded.
+You can read the full story in the [release notes](https://golang.org/doc/go1.1).
+
+As per our [compatibility guidelines](https://golang.org/doc/go1compat.html),
+Go 1.1 remains compatible with Go 1.0 and we recommend all Go users upgrade to the new release.
+
+All this would not have been possible without the help of our contributors from
+the open source community.
+Since Go 1.0, the core received more than 2600 commits from 161 people outside Google.
+Thank you everyone for your time and effort.
+In particular, we would like to thank Shenghou Ma,
+Rémy Oudompheng, Dave Cheney, Mikio Hara,
+Alex Brainman, Jan Ziak, and Daniel Morsing for their outstanding contributions.
+
+To grab the new release, follow the usual [installation instructions](https://golang.org/doc/install). Happy hacking!
