| <h2 id="introduction">DRAFT RELEASE NOTES - Introduction to Go 1.11</h2> |
| |
| <p> |
| <strong> |
| 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> <!-- CL 94255, CL 115038, etc --> |
| 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> |
| |
| <p><!-- CL 107935 --> |
| The race detector is now supported on <code>linux/ppc64le</code> |
| and, to a lesser extent, on <code>netbsd/amd64</code>. The NetBSD race detector support |
| has <a href="https://golang.org/issue/26403">known issues</a>. |
| </p> |
| |
| <p><!-- CL 93875 --> |
| The build modes <code>c-shared</code> and <code>c-archive</code> are now supported on |
| <code>freebsd/amd64</code>. |
| </p> |
| |
| <p id="mips"><!-- CL 108475 --> |
| On 64-bit MIPS systems, the new environment variable settings |
| <code>GOMIPS64=hardfloat</code> (the default) and |
| <code>GOMIPS64=softfloat</code> select whether to use |
| hardware instructions or software emulation for floating-point computations. |
| For 32-bit systems, the environment variable is still <code>GOMIPS</code>, |
| as <a href="go1.10#mips">added in Go 1.10</a>. |
| </p> |
| |
| <h3 id="wasm">WebAssembly</h3> |
| <p> |
| Go 1.11 adds an experimental port to WebAssembly (<code>js/wasm</code>). |
| </p> |
| <p> |
| Go programs currently compile to one WebAssembly module that |
| includes the Go runtime for goroutine scheduling, garbage |
| collection, maps, etc. |
| As a result, the resulting size is at minimum around |
| 2 MB, or 500 KB compressed. Go programs can call into JavaScript |
| using the new experimental |
| <a href="/pkg/syscall/js/"><code>syscall/js</code></a> package. |
| Binary size and interop with other languages has not yet been a |
| priority but may be addressed in future releases. |
| </p> |
| <p> |
| As a result of the addition of the new <code>GOOS</code> value |
| "<code>js</code>" and <code>GOARCH</code> value "<code>wasm</code>", |
| Go files named <code>*_js.go</code> or <code>*_wasm.go</code> will |
| now be <a href="/pkg/go/build/#hdr-Build_Constraints">ignored by Go |
| tools</a> except when those GOOS/GOARCH values are being used. |
| If you have existing filenames matching those patterns, you will need to rename them. |
| </p> |
| |
| <h2 id="tools">Tools</h2> |
| |
| <h3 id="modules">Modules, package versioning, and dependency management</h3> |
| <p> |
| <strong> |
| NOTE: This is not present in go1.11beta1 but will be available in future |
| betas and subsequent releases. |
| </strong> |
| 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. |
| </p> |
| |
| <p> |
| 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 <a href="https://golang.org/issue/new">file issues</a> |
| so we can fix them. |
| </p> |
| |
| <p> |
| TODO: Link to intro doc. |
| </p> |
| |
| <h3 id="importpath">Import path restriction</h3> |
| |
| <p> |
| Because Go module support assigns special meaning to the |
| <code>@</code> symbol in command line operations, |
| the <code>go</code> command now disallows the use of |
| import paths containing <code>@</code> symbols. |
| Such import paths were never allowed by <code>go</code> <code>get</code>, |
| so this restriction can only affect users building |
| custom GOPATH trees by other means. |
| </p> |
| |
| <h3 id="gopackages">Package loading</h2> |
| |
| <p> |
| TODO: Note about go/build versus golang.org/x/tools/go/packages. |
| </p> |
| |
| <h3 id="gocache">Build cache requirement</h2> |
| |
| <p> |
| Go 1.11 will be the last release to support setting the environment |
| variable <code>GOCACHE=off</code> to disable the |
| <a href="/cmd/go/#hdr-Build_and_test_caching">build cache</a>, |
| introduced in Go 1.10. |
| Starting in Go 1.12, the build cache will be required, |
| as a step toward eliminating <code>$GOPATH/pkg</code>. |
| 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 <a href="https://golang.org/issue/new">file an issue</a> to let us know about them. |
| </p> |
| |
| <h2 id="tools">Tools</h2> |
| |
| <h3 id="test">Test</h3> |
| |
| <p> |
| Since Go1.10, the <code>go</code> <code>test</code> command runs |
| <code>go</code> <code>vet</code> on the package being tested, |
| to identify problems before running the test. Since <code>vet</code> |
| typechecks the code with <a href="/pkg/go/types/">go/types</a> |
| before running, tests that do not typecheck will now fail. |
| |
| In particular, tests that contain an unused variable inside a |
| closure compiled with Go1.10, because the Go compiler incorrectly |
| accepted them (<a href="https://golang.org/issues/3059">Issue #3059</a>), |
| but will now fail, since <code>go/types</code> correctly reports an |
| "unused variable" error in this case. |
| </p> |
| |
| |
| <h3 id="vet">Vet</h3> |
| |
| <p><!-- CL 108555 --> |
| The <a href="/cmd/vet/"><code>go</code> <code>vet</code></a> |
| command now reports a fatal error when the package under analysis |
| does not typecheck. Previously, a type checking error simply caused |
| a warning to be printed, and <code>vet</code> to exit with status 1. |
| </p> |
| |
| |
| <h2 id="library">Core library</h2> |
| |
| <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. |

| On Windows, several fields were changed from <code>uintptr</code> to a new |
| <a href="/pkg/syscall/?GOOS=windows&GOARCH=amd64#Pointer"><code>Pointer</code></a> |
| type to avoid problems with Go's garbage collector. The same change was made |
| to the <a href="https://godoc.org/golang.org/x/sys/windows"><code>golang.org/x/sys/windows</code></a> |
| package. For any code affected, users should first migrate away from the <code>syscall</code> |
| package to the <code>golang.org/x/sys/windows</code> package, and then change |
| to using the <code>Pointer</code>, while obeying the |
| <a href="/pkg/unsafe/#Pointer"><code>unsafe.Pointer</code> conversion rules</a>. |
