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.
< / strong >
< / p >
< p >
The latest Go release, version 1.11, arrives six months after < a href = "go1.10" > Go 1.10< / a > .
Most of its changes are in the implementation of the toolchain, runtime, and libraries.
As always, the release maintains the Go 1 < a href = "/doc/go1compat.html" > promise of compatibility< / a > .
We expect almost all Go programs to continue to compile and run as before.
< / p >
< h2 id = "language" > Changes to the language< / h2 >
< p >
There are no changes to the language specification.
< / p >
< h2 id = "ports" > Ports< / h2 >
< p >
As < a href = "go1.10#ports" > announced in the Go 1.10 release notes< / a > , 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.
< / p >
< p >
There are < a href = "https://golang.org/issue/25206" > known issues< / a > with NetBSD on i386 hardware.

< p >
All of the changes to the standard library are minor.
< / p >
< h3 id = "minor_library_changes" > Minor changes to the library< / h3 >
< p >
As always, there are various minor changes and updates to the library,
made with the Go 1 < a href = "/doc/go1compat" > promise of compatibility< / a >
in mind.
