These are work-in-progress 22 release notes. Go 1.9 is expected to be released in August 2017. 23 </strong></p> 24 25 <p> 26 The latest Go release, version 1.9, arrives six months after <a href="go1.8">Go 1.8</a> 27 and is the tenth release in the <a href="https://golang.org/doc/devel/release.html">Go 1.x series</a>. 28 Most of its changes are in the implementation of the toolchain, runtime, and libraries. 29 There are no changes to the language specification. 30 As always, the release maintains the Go 1 <a href="/doc/go1compat.html">promise of compatibility</a>. 31 We expect almost all Go programs to continue to compile and run as before. 32 </p> 33 34 <p> 35 The release 36 adds <a href="#monotonic-time">transparent monotonic time support</a>, 37 <a href="#parallel-compile">parallelizes compilation of functions</a> within a package, 38 better supports <a href="#test-helper">test helper functions</a>, 39 and includes a new <a href="#math-bits">bit manipulation package</a>. 40 </p> 41 42 <h2 id="ports">Ports</h2> 43 44 <p> 45 There are no new supported operating systems or processor 46 architectures in this release. 47 </p> 48 49 <h3 id="power8">ppc64x requires Power8</h3> 50 51 <p> <!-- CL 36725, CL 36832 --> 52 Both <code>GOARCH=ppc64</code> and <code>GOARCH=ppc64le</code> now 53 require at least Power8 support. In previous releases, 54 only <code>GOARCH=ppc64le</code> required Power8 and the big 55 endian <code>ppc64</code> architecture supported older 56 hardware. 57 <p> 58 59 <h3 id="known_issues">Known Issues</h3> 60 61 <p> 62 There are some instabilities on FreeBSD that are known but not understood. 63 These can lead to program crashes in rare cases. 64 See <a href="https://golang.org/issue/15658">issue 15658</a>. 65 Any help in solving this FreeBSD-specific issue would be appreciated. 66 </p> 67 68 <h2 id="tools">Tools</h2> 69 70 <h3 id="parallel-compile">Parallel Compilation</h3> 71 72 <p> 73 The Go compiler now supports compiling a package's functions in parallel, taking 74 advantage of multiple cores. This is in addition to the <code>go</code> command's 75 existing support for parallel compilation of separate packages. 76 Parallel compilation is on by default, but can be disabled by setting the 77 environment variable <code>GO19CONCURRENTCOMPILATION</code> to <code>0</code>. 78 </p> 79 80 <!-- CL 42028: https://golang.org/cl/42028: cmd/asm: fix operand order of ARM's MULA instruction --> 81 <!-- CL 36031: https://golang.org/cl/36031: cmd/doc: truncate long lists of arguments --> 82 <!-- CL 38438: https://golang.org/cl/38438: cmd/doc: implement "go doc struct.field" --> 83 <!-- CL 38745: https://golang.org/cl/38745: cmd/go: exclude vendored packages from ... matches --> 84 <!-- CL 38757: https://golang.org/cl/38757: cmd/go: add -json flag to go env --> 85 <!-- CL 40112: https://golang.org/cl/40112: cmd/go: allow full flag processing in go vet --> 86 <!-- CL 43855: https://golang.org/cl/43855: cmd/go: include GOARM and GO386 in computed build ID --> 87 <!-- CL 44210: https://golang.org/cl/44210: cmd/internal/dwarf: update to DWARF4, emit frame_base --> 88 <!-- CL 42990: https://golang.org/cl/42990: cmd/internal/obj/x86: add ADDSUBPS/PD --> 89 <!-- CL 36983: https://golang.org/cl/36983: cmd/link: write dwarf sections --> 90 <!-- CL 40331: https://golang.org/cl/40331: cmd/link,runtime/cgo: enable PT_TLS generation on OpenBSD --> 91 <!-- CL 38343: https://golang.org/cl/38343: cmd/pprof: use proxy from environment --> 92 <!-- CL 36015: https://golang.org/cl/36015: cmd/trace: Record mark assists in execution traces --> 93 94 95 <h2 id="performance">Performance</h2> 96 97 <p> 98 As always, the changes are so general and varied that precise 99 statements about performance are difficult to make.
