Go 1.11 is not yet released. These are work-in-progress release notes. Go 1.11 is expected to be released in August 2018.
The latest Go release, version 1.11, arrives six months after Go 1.10. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before.
There are no changes to the language specification.
As announced in the Go 1.10 release notes, Go 1.11 now requires OpenBSD 6.2 or later, macOS 10.10 Yosemite or later, or Windows 7 or later; Support for previous versions of these operating systems has been removed.
There are known issues with NetBSD on i386 hardware.
TODO: PPC64LE race detector support
Go 1.11 adds an experimental port to WebAssembly (js/wasm).
NOTE: This is not present in go1.11beta1 but will be available in future betas and subsequent releases. Go 1.11 adds experimental support for a new concept called “modules,” an alternative to GOPATH with integrated support for versioning and package distribution. Using modules, developers are no longer confined to working inside GOPATH, version dependency information is explicit yet lightweight, and builds are more reliable and reproducible.
Module support is considered experimental. Details are likely to change in response to feedback from Go 1.11 users, and we have more tools planned. Although the details of module support may change, projects that convert to modules using Go 1.11 will continue to work with Go 1.12 and later. If you encounter bugs using modules, please file issues so we can fix them.
TODO: Link to intro doc.
TODO: Note about go/build versus golang.org/x/tools/go/packages.
Go 1.11 will be the last release to support setting the environment
variable GOCACHE=off to disable the
build cache,
introduced in Go 1.10.
Starting in Go 1.12, the build cache will be required,
as a step toward eliminating $GOPATH/pkg.
The module and package loading support described above
already require that the build cache be enabled.
If you have disabled the build cache to avoid problems you encountered,
please file an issue to let us know about them.
All of the changes to the standard library are minor.
As always, there are various minor changes and updates to the library, made with the Go 1 promise of compatibility in mind.
