+## Binary Distribution Notes
+
+If you have just untarred a binary Go distribution, you need to set
+the environment variable $GOROOT to the full path of the go
+directory (the one containing this file).  You can omit the
+variable if you unpack it into /usr/local/go, or if you rebuild
+from sources by running all.bash (see doc/install-source.html).
+You should also add the Go binary directory $GOROOT/bin
+to your shell's path.
+
+For example, if you extracted the tar file into $HOME/go, you might
+put the following in your .profile:
+
+	export GOROOT=$HOME/go
+	export PATH=$PATH:$GOROOT/bin
+
+See https://golang.org/doc/install or doc/install.html for more details.

-
-<p><strong>
-    Go 1.9 is not yet released. These are work-in-progress
-    release notes. Go 1.9 is expected to be released in August 2017.
-</strong></p>
-
-<p>
-  The latest Go release, version 1.9, arrives six months
-  after <a href="go1.8">Go 1.8</a> and is the tenth release in
-  the <a href="https://golang.org/doc/devel/release.html">Go 1.x
-  series</a>.
-  There are two <a href="#language">changes to the language</a>:
-  adding support for type aliases and defining when implementations
-  may fuse floating point operations.
-  Most of the 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>
-
-<p>
-  The release
-  adds <a href="#monotonic-time">transparent monotonic time support</a>,
-  <a href="#parallel-compile">parallelizes compilation of functions</a> within a package,
-  better supports <a href="#test-helper">test helper functions</a>,
-  includes a new <a href="#math-bits">bit manipulation package</a>,
-  and has a new <a href="#sync-map">concurrent map type</a>.
-</p>
-
-<h2 id="language">Changes to the language</h2>
-
-<p>
-  There are two changes to the language.
-</p>
-<p>
-  Go now supports type aliases to support gradual code repair while
-  moving a type between packages.
-  The <a href="https://golang.org/design/18130-type-alias">type alias
-  design document</a>
-  and <a href="https://talks.golang.org/2016/refactor.article">an
-  article on refactoring</a> cover the problem in detail.
-  In short, a type alias declaration has the form:
-</p>
-
-<pre>
-type T1 = T2
-</pre>
-
-<p>
-  This declaration introduces an alias name <code>T1</code>—an
-  alternate spelling—for the type denoted by <code>T2</code>; that is,
-  both <code>T1</code> and <code>T2</code> denote the same type.
-</p>
-
-<p> <!-- CL 40391 -->
-  A smaller language change is that the
-  <a href="/ref/spec#Floating_point_operators">language specification
-  now states</a> when implementations are allowed to fuse floating
-  point operations together, such as by using an architecture's "fused
-  multiply and add" (FMA) instruction to compute <code>x*y</code>&nbsp;<code>+</code>&nbsp;<code>z</code>
-  without rounding the intermediate result <code>x*y</code>.
-  To force the intermediate rounding, write <code>float64(x*y)</code>&nbsp;<code>+</code>&nbsp;<code>z</code>.
-</p>
-
-<h2 id="ports">Ports</h2>
-
-<p>
-  There are no new supported operating systems or processor
-  architectures in this release.
-</p>
-
-<h3 id="power8">ppc64x requires POWER8</h3>
-
-<p> <!-- CL 36725, CL 36832 -->
-  Both <code>GOARCH=ppc64</code> and <code>GOARCH=ppc64le</code> now
-  require at least POWER8 support. In previous releases,
-  only <code>GOARCH=ppc64le</code> required POWER8 and the big
-  endian <code>ppc64</code> architecture supported older
-  hardware.
-<p>
-
-<h3 id="freebsd">FreeBSD</h3>
-
-<p>
-  Go 1.9 is the last release that will run on FreeBSD 9.3,
-  which is already
-  <a href="https://www.freebsd.org/security/unsupported.html">unsupported by FreeBSD</a>.
-  Go 1.10 will require FreeBSD 10.3+.
-</p>
-
-<h3 id="openbsd">OpenBSD 6.0</h3>
-
-<p> <!-- CL 40331 -->
-  Go 1.9 now enables PT_TLS generation for cgo binaries and thus
-  requires OpenBSD 6.0 or newer. Go 1.9 no longer supports
-  OpenBSD 5.9.
-<p>
-
-<h3 id="known_issues">Known Issues</h3>
-
-<p>
-  There are some instabilities on FreeBSD that are known but not understood.
-  These can lead to program crashes in rare cases.
-  See <a href="https://golang.org/issue/15658">issue 15658</a>.
-  Any help in solving this FreeBSD-specific issue would be appreciated.
-</p>
-
-<p>
-  Go stopped running NetBSD builders during the Go 1.9 development
-  cycle due to NetBSD kernel crashes, up to and including NetBSD 7.1.
-  As Go 1.9 is being released, NetBSD 7.1.1 is being released with a fix.
-  However, at this time we have no NetBSD builders passing our test suite.
-  Any help investigating the
-  <a href="https://github.com/golang/go/labels/OS-NetBSD">various NetBSD issues</a>
-  would be appreciated.
-</p>
-
-<h2 id="tools">Tools</h2>
-
-<h3 id="parallel-compile">Parallel Compilation</h3>
-
-<p>
-  The Go compiler now supports compiling a package's functions in parallel, taking
-  advantage of multiple cores. This is in addition to the <code>go</code> command's
-  existing support for parallel compilation of separate packages.
-  Parallel compilation is on by default, but it can be disabled by setting the
-  environment variable <code>GO19CONCURRENTCOMPILATION</code> to <code>0</code>.
-</p>
-
-<h3 id="vendor-dotdotdot">Vendor matching with ./...</h3>
-
-<p><!-- CL 38745 -->
-  By popular request, <code>./...</code> no longer matches packages
-  in <code>vendor</code> directories in tools accepting package names,
-  such as <code>go</code> <code>test</code>. To match vendor
-  directories, write <code>./vendor/...</code>.
-</p>
-
-<h3 id="compiler">Compiler Toolchain</h3>
-
-<p><!-- CL 37441 -->
-  Complex division is now C99-compatible. This has always been the
-  case in gccgo and is now fixed in the gc toolchain.
-</p>
-
-<p> <!-- CL 36983 -->
-  The linker will now generate DWARF information for cgo executables on Windows.
-</p>
-
-<p> <!-- CL 44210, CL 40095 -->
-  The compiler now includes lexical scopes in the generated DWARF if the
-  <code>-N -l</code> flags are provided, allowing
-  debuggers to hide variables that are not in scope. The <code>.debug_info</code>
-  section is now DWARF version 4.
-</p>
-
-<p> <!-- CL 43855 -->
-  The values of <code>GOARM</code> and <code>GO386</code> now affect a
-  compiled package's build ID, as used by the <code>go</code> tool's
-  dependency caching.
-</p>
-
-<h3 id="asm">Assembler</h3>
-
-<p> <!-- CL 42028 -->
-  The four-operand ARM <code>MULA</code> instruction is now assembled correctly,
-  with the addend register as the third argument and the result
-  register as the fourth and final argument.
-  In previous releases, the two meanings were reversed.
-  The three-operand form, in which the fourth argument is implicitly
-  the same as the third, is unaffected.
-  Code using four-operand <code>MULA</code> instructions
-  will need to be updated, but we believe this form is very rarely used.
-  <code>MULAWT</code> and <code>MULAWB</code> were already
-  using the correct order in all forms and are unchanged.
-</p>
-
-<p> <!-- CL 42990 -->
-  The assembler now supports <code>ADDSUBPS/PD</code>, completing the
-  two missing x86 SSE3 instructions.
-</p>
-
-<h3 id="go-doc">Doc</h3>
-
-<p><!-- CL 36031 -->
-  Long lists of arguments are now truncated. This improves the readability
-  of <code>go</code> <code>doc</code> on some generated code.
-</p>
-
-<p><!-- CL 38438 -->
-  Viewing documentation on struct fields is now supported.
-  For example, <code>go</code> <code>doc</code> <code>http.Client.Jar</code>.
-</p>
-
-<h3 id="go-env-json">Env</h3>
-
-<p> <!-- CL 38757 -->
-  The new <code>go</code> <code>env</code> <code>-json</code> flag
-  enables JSON output, instead of the default OS-specific output
-  format.
-</p>
-
-<h3 id="go-test-list">Test</h3>
-
-<p> <!-- CL 41195 -->
-  The <a href="/cmd/go/#hdr-Description_of_testing_flags"><code>go</code> <code>test</code></a>
-  command accepts a new <code>-list</code> flag, which takes a regular
-  expression as an argument and prints to stdout the name of any
-  tests, benchmarks, or examples that match it, without running them.
-</p>
-
-
-<h3 id="go-tool-pprof">Pprof</h3>
-
-<p> <!-- CL 34192 -->
-  Profiles produced by the <code>runtime/pprof</code> package now
-  include symbol information, so they can be viewed
-  in <code>go</code> <code>tool</code> <code>pprof</code>
-  without the binary that produced the profile.
-</p>
-
-<p> <!-- CL 38343 -->
-  The <code>go</code> <code>tool</code> <code>pprof</code> command now
-  uses the HTTP proxy information defined in the environment, using
-  <a href="/pkg/net/http/#ProxyFromEnvironment"><code>http.ProxyFromEnvironment</code></a>.
-</p>
-
-<h3 id="vet">Vet</h3>
-
-<!-- CL 40112 -->
-<p>
-  The <a href="/cmd/vet/"><code>vet</code> command</a>
-  has been better integrated into the
-  <a href="/cmd/go/"><code>go</code> tool</a>,
-  so <code>go</code> <code>vet</code> now supports all standard build
-  flags while <code>vet</code>'s own flags are now available
-  from <code>go</code> <code>vet</code> as well as
-  from <code>go</code> <code>tool</code> <code>vet</code>.
-</p>
-
-<h3 id="gccgo">Gccgo</h3>
-
-<p>
-Due to the alignment of Go's semiannual release schedule with GCC's
-annual release schedule,
-GCC release 7 contains the Go 1.8.3 version of gccgo.
-We expect that the next release, GCC 8, will contain the Go 1.10
-version of gccgo.

-
-<h2 id="runtime">Runtime</h2>
-
-<h3 id="callersframes">Call stacks with inlined frames</h3>
-
-<p>
-  Users of
-  <a href="/pkg/runtime#Callers"><code>runtime.Callers</code></a>
-  should avoid directly inspecting the resulting PC slice and instead use
-  <a href="/pkg/runtime#CallersFrames"><code>runtime.CallersFrames</code></a>
-  to get a complete view of the call stack, or
-  <a href="/pkg/runtime#Caller"><code>runtime.Caller</code></a>
-  to get information about a single caller.
-  This is because an individual element of the PC slice cannot account
-  for inlined frames or other nuances of the call stack.
-</p>
-
-<p>
-  Specifically, code that directly iterates over the PC slice and uses
-  functions such as
-  <a href="/pkg/runtime#FuncForPC"><code>runtime.FuncForPC</code></a>
-  to resolve each PC individually will miss inlined frames.
-  To get a complete view of the stack, such code should instead use
-  <code>CallersFrames</code>.
-  Likewise, code should not assume that the length returned by
-  <code>Callers</code> is any indication of the call depth.
-  It should instead count the number of frames returned by
-  <code>CallersFrames</code>.
-</p>
-
-<p>
-  Code that queries a single caller at a specific depth should use
-  <code>Caller</code> rather than passing a slice of length 1 to
-  <code>Callers</code>.
-</p>
-
-<p>
-  <a href="/pkg/runtime#CallersFrames"><code>runtime.CallersFrames</code></a>
-  has been available since Go 1.7, so code can be updated prior to
-  upgrading to Go 1.9.
-</p>
-
-<h2 id="performance">Performance</h2>
-
-<p>
-  As always, the changes are so general and varied that precise
-  statements about performance are difficult to make.  Most programs
-  should run a bit faster, due to speedups in the garbage collector,
-  better generated code, and optimizations in the core library.
-</p>
-
-<h3 id="gc">Garbage Collector</h3>
-
-<p> <!-- CL 37520 -->
-  Library functions that used to trigger stop-the-world garbage
-  collection now trigger concurrent garbage collection.
-
-  Specifically, <a href="/pkg/runtime/#GC"><code>runtime.GC</code></a>,
-  <a href="/pkg/runtime/debug/#SetGCPercent"><code>debug.SetGCPercent</code></a>,
-  and
-  <a href="/pkg/runtime/debug/#FreeOSMemory"><code>debug.FreeOSMemory</code></a>,
-  now trigger concurrent garbage collection, blocking only the calling
-  goroutine until the garbage collection is done.
-</p>
-
-<p> <!-- CL 34103, CL 39835 -->
-  The
-  <a href="/pkg/runtime/debug/#SetGCPercent"><code>debug.SetGCPercent</code></a>
-  function only triggers a garbage collection if one is immediately
-  necessary because of the new GOGC value.
-  This makes it possible to adjust GOGC on-the-fly.
-</p>
-
-<p> <!-- CL 38732 -->
-  Large object allocation performance is significantly improved in
-  applications using large (&gt;50GB) heaps containing many large
-  objects.
-</p>
-
-<p> <!-- CL 34937 -->
-  The <a href="/pkg/runtime/#ReadMemStats"><code>runtime.ReadMemStats</code></a>
-  function now takes less than 100µs even for very large heaps.
-</p>
-
-<h2 id="library">Core library</h2>
-
-<h3 id="monotonic-time">Transparent Monotonic Time support</h3>
-
-<p> <!-- CL 36255 -->
-  The <a href="/pkg/time/"><code>time</code></a> package now transparently
-  tracks monotonic time in each <a href="/pkg/time/#Time"><code>Time</code></a>
-  value, making computing durations between two <code>Time</code> values
-  a safe operation in the presence of wall clock adjustments.
-  See the <a href="/pkg/time/#hdr-Monotonic_Clocks">package docs</a> and
-  <a href="https://golang.org/design/12914-monotonic">design document</a>
-  for details.
-</p>
-
-<h3 id="math-bits">New bit manipulation package</h3>
-
-<p> <!-- CL 36315 -->
-  Go 1.9 includes a new package,
-  <a href="/pkg/math/bits/"><code>math/bits</code></a>, with optimized
-  implementations for manipulating bits. On most architectures,
-  functions in this package are additionally recognized by the
-  compiler and treated as intrinsics for additional performance.
-</p>
-
-<h3 id="test-helper">Test Helper Functions</h3>
-
-<p> <!-- CL 38796 -->
-  The
-  new <a href="/pkg/testing/#T.Helper"><code>(*T).Helper</code></a>
-  and <a href="/pkg/testing/#B.Helper"><code>(*B).Helper</code></a>
-  methods mark the calling function as a test helper function.  When
-  printing file and line information, that function will be skipped.
-  This permits writing test helper functions while still having useful
-  line numbers for users.
-</p>
-
-<h3 id="sync-map">Concurrent Map</h3>
-
-<p> <!-- CL 36617 -->
-  The new <a href="/pkg/sync/#Map"><code>Map</code></a> type
-  in the <a href="/pkg/sync/"><code>sync</code></a> package
-  is a concurrent map with amortized-constant-time loads, stores, and
-  deletes. It is safe for multiple goroutines to call a <code>Map</code>'s methods
-  concurrently.

-<h3 id="pprof-labels">Profiler Labels</h3>
-
-<p><!-- CL 34198 -->
-  The <a href="/pkg/runtime/pprof"><code>runtime/pprof</code> package</a>

-  Labels form a key-value map that is used to distinguish calls of the

-  with the <a href="/cmd/pprof/"><code>pprof</code> command</a>.
-  The <code>pprof</code> package's

-Does Go have a runtime?</h3>
-
-<p>
-Go does have an extensive library, called the <em>runtime</em>,
-that is part of every Go program.
-The runtime library implements garbage collection, concurrency,
-stack management, and other critical features of the Go language.
-Although it is more central to the language, Go's runtime is analogous
-to <code>libc</code>, the C library.
-</p>
-
-<p>
-It is important to understand, however, that Go's runtime does not
