+
+<ul>
+	<li>Go programmers typically keep all their Go code in a single <i>workspace</i>.</li>
+	<li>A workspace contains many version control <i>repositories</i>
+	    (managed by Git, for example).</li>
+	<li>Each repository contains one or more <i>packages</i>.</li>
+	<li>Each package consists of one or more Go source files in a single directory.</li>
+	<li>The path to a package's directory determines its <i>import path</i>.</li>
+</ul>
+
+<p>
+Note that this differs from other programming environments in which every
+project has a separate workspace and workspaces are closely tied to version
+control repositories.
+</p>
+
+<h3 id="Workspaces">Workspaces</h3>
+
+<p>
+A workspace is a directory hierarchy with three directories at its root:
+</p>
+
+<ul>
+<li><code>src</code> contains Go source files,
+<li><code>pkg</code> contains package objects, and
+<li><code>bin</code> contains executable commands.
+</ul>
+
+<p>
+The <code>go</code> tool builds source packages and installs the resulting
+binaries to the <code>pkg</code> and <code>bin</code> directories.
+</p>
+
+<p>
+The <code>src</code> subdirectory typically contains multiple version control
+repositories (such as for Git or Mercurial) that track the development of one
+or more source packages.
+</p>
+
+<p>
+To give you an idea of how a workspace looks in practice, here's an example:
+</p>
+
+<pre>
+bin/
+    hello                          # command executable
+    outyet                         # command executable
+pkg/
+    linux_amd64/
+        github.com/golang/example/
+            stringutil.a           # package object
+src/
+    <a href="https://github.com/golang/example/">github.com/golang/example/</a>
+        .git/                      # Git repository metadata
+	hello/
+	    hello.go               # command source
+	outyet/
+	    main.go                # command source
+	    main_test.go           # test source
+	stringutil/
+	    reverse.go             # package source
+	    reverse_test.go        # test source
+    <a href="https://golang.org/x/image/">golang.org/x/image/</a>
+        .git/                      # Git repository metadata
+	bmp/
+	    reader.go              # package source
+	    writer.go              # package source
+    ... (many more repositories and packages omitted) ...
+</pre>
+
+<p>
+The tree above shows a workspace containing two repositories
+(<code>example</code> and <code>image</code>).
+The <code>example</code> repository contains two commands (<code>hello</code>
+and <code>outyet</code>) and one library (<code>stringutil</code>).
+The <code>image</code> repository contains the <code>bmp</code> package
+and <a href="https://godoc.org/golang.org/x/image">several others</a>.
+</p>
+
+<p>
+A typical workspace contains many source repositories containing many
+packages and commands. Most Go programmers keep <i>all</i> their Go source code
+and dependencies in a single workspace.
+</p>
+
+<p>
+Commands and libraries are built from different kinds of source packages.
+We will discuss the distinction <a href="#PackageNames">later</a>.
+</p>
+
+
+<h3 id="GOPATH">The <code>GOPATH</code> environment variable</h3>
+
+<p>
+The <code>GOPATH</code> environment variable specifies the location of your
+workspace. It defaults to a directory named <code>go</code> inside your home directory,
+so <code>$HOME/go</code> on Unix,
+<code>$home/go</code> on Plan 9,
+and <code>%USERPROFILE%\go</code> (usually <code>C:\Users\YourName\go</code>) on Windows.
+If you would like to work in a different location, you will need to set
+<code>GOPATH</code> to the path to that directory.
+(Another common setup is to set <code>GOPATH=$HOME</code>.)
+Note that <code>GOPATH</code> must <b>not</b> be the
+same path as your Go installation.
+</p>
+
+<p>
+The command <code>go</code> <code>env</code> <code>GOPATH</code>
+prints the effective current <code>GOPATH</code>;
+it prints the default location if the environment variable is unset.
+</p>
+
+<p>
+For convenience, add the workspace's <code>bin</code> subdirectory
+to your <code>PATH</code>:
+</p>
+
+<pre>
+$ <b>export PATH=$PATH:$(go env GOPATH)/bin</b>
+</pre>
+
+<p>
+The scripts in the rest of this document use <code>$GOPATH</code>
+instead of <code>$(go env GOPATH)</code> for brevity.
+To make the scripts run as written
+if you have not set GOPATH,
+you can substitute $HOME/go in those commands
+or else run:
+</p>
+
+<pre>
+$ <b>export GOPATH=$(go env GOPATH)</b>
+</pre>
+
+<p>
+To learn more about the <code>GOPATH</code> environment variable, see
+<a href="/cmd/go/#hdr-GOPATH_environment_variable"><code>'go help gopath'</code></a>.
+</p>
+
+<p>
+To use a custom workspace location,
+<a href="https://golang.org/wiki/SettingGOPATH">set the <code>GOPATH</code> environment variable</a>.
+</p>
+
+<h3 id="ImportPaths">Import paths</h3>
+
+<p>
+An <i>import path</i> is a string that uniquely identifies a package.
+A package's import path corresponds to its location inside a workspace
+or in a remote repository (explained below).
+</p>
+
+<p>
+The packages from the standard library are given short import paths such as
+<code>"fmt"</code> and <code>"net/http"</code>.
+For your own packages, you must choose a base path that is unlikely to
+collide with future additions to the standard library or other external
+libraries.
+</p>
+
+<p>
+If you keep your code in a source repository somewhere, then you should use the
+root of that source repository as your base path.
+For instance, if you have a <a href="https://github.com/">GitHub</a> account at
+<code>github.com/user</code>, that should be your base path.
+</p>
+
+<p>
+Note that you don't need to publish your code to a remote repository before you
+can build it. It's just a good habit to organize your code as if you will
+publish it someday. In practice you can choose any arbitrary path name,
+as long as it is unique to the standard library and greater Go ecosystem.
+</p>
+
+<p>
+We'll use <code>github.com/user</code> as our base path. Create a directory
+inside your workspace in which to keep source code:
+</p>
+
+<pre>
+$ <b>mkdir -p $GOPATH/src/github.com/user</b>
+</pre>
+
+
+<h3 id="Command">Your first program</h3>
+
+<p>
+To compile and run a simple program, first choose a package path (we'll use
+<code>github.com/user/hello</code>) and create a corresponding package directory
+inside your workspace:
+</p>
+
+<pre>
+$ <b>mkdir $GOPATH/src/github.com/user/hello</b>
+</pre>
+
+<p>
+Next, create a file named <code>hello.go</code> inside that directory,
+containing the following Go code.
+</p>
+
+<pre>
+package main
+
+import "fmt"
+
+func main() {
+	fmt.Printf("Hello, world.\n")
+}
+</pre>
+
+<p>
+Now you can build and install that program with the <code>go</code> tool:
+</p>
+
+<pre>
+$ <b>go install github.com/user/hello</b>
+</pre>
+
+<p>
+Note that you can run this command from anywhere on your system. The
+<code>go</code> tool finds the source code by looking for the
+<code>github.com/user/hello</code> package inside the workspace specified by
+<code>GOPATH</code>.
+</p>
+
+<p>
+You can also omit the package path if you run <code>go install</code> from the
+package directory:
+</p>
+
+<pre>
+$ <b>cd $GOPATH/src/github.com/user/hello</b>
+$ <b>go install</b>
+</pre>
+
+<p>
+This command builds the <code>hello</code> command, producing an executable
+binary. It then installs that binary to the workspace's <code>bin</code>
+directory as <code>hello</code> (or, under Windows, <code>hello.exe</code>).
+In our example, that will be <code>$GOPATH/bin/hello</code>, which is
+<code>$HOME/work/bin/hello</code>.
+</p>
+
+<p>
+The <code>go</code> tool will only print output when an error occurs, so if
+these commands produce no output they have executed successfully.
+</p>
+
+<p>
+You can now run the program by typing its full path at the command line:
+</p>
+
+<pre>
+$ <b>$GOPATH/bin/hello</b>
+Hello, world.
+</pre>
+
+<p>
+Or, as you have added <code>$GOPATH/bin</code> to your <code>PATH</code>,
+just type the binary name:
+</p>
+
+<pre>
+$ <b>hello</b>
+Hello, world.
+</pre>
+
+<p>
+If you're using a source control system, now would be a good time to initialize
+a repository, add the files, and commit your first change. Again, this step is
+optional: you do not need to use source control to write Go code.
+</p>
+
+<pre>
+$ <b>cd $GOPATH/src/github.com/user/hello</b>
+$ <b>git init</b>
+Initialized empty Git repository in /home/user/work/src/github.com/user/hello/.git/
+$ <b>git add hello.go</b>
+$ <b>git commit -m "initial commit"</b>
+[master (root-commit) 0b4507d] initial commit
+ 1 file changed, 1 insertion(+)
+  create mode 100644 hello.go
+</pre>
+
+<p>
+Pushing the code to a remote repository is left as an exercise for the reader.
+</p>
+
+
+<h3 id="Library">Your first library</h3>
+
+<p>
+Let's write a library and use it from the <code>hello</code> program.
+</p>
+
+<p>
+Again, the first step is to choose a package path (we'll use
+<code>github.com/user/stringutil</code>) and create the package directory:
+</p>
+
+<pre>
+$ <b>mkdir $GOPATH/src/github.com/user/stringutil</b>
+</pre>
+
+<p>
+Next, create a file named <code>reverse.go</code> in that directory with the
+following contents.
+</p>
+
+<pre>
+// Package stringutil contains utility functions for working with strings.
+package stringutil
+
+// Reverse returns its argument string reversed rune-wise left to right.
+func Reverse(s string) string {
+	r := []rune(s)
+	for i, j := 0, len(r)-1; i &lt; len(r)/2; i, j = i+1, j-1 {
+		r[i], r[j] = r[j], r[i]
+	}
+	return string(r)
+}
+</pre>
+
+<p>
+Now, test that the package compiles with <code>go build</code>:
+</p>
+
+<pre>
+$ <b>go build github.com/user/stringutil</b>
+</pre>
+
+<p>
+Or, if you are working in the package's source directory, just:
+</p>
+
+<pre>
+$ <b>go build</b>
+</pre>
+
+<p>
+This won't produce an output file. To do that, you must use <code>go
+install</code>, which places the package object inside the <code>pkg</code>
+directory of the workspace.
+</p>
+
+<p>
+After confirming that the <code>stringutil</code> package builds,
+modify your original <code>hello.go</code> (which is in
+<code>$GOPATH/src/github.com/user/hello</code>) to use it:
+</p>
+
+<pre>
+package main
+
+import (
+	"fmt"
+
+	<b>"github.com/user/stringutil"</b>
+)
+
+func main() {
+	fmt.Printf(stringutil.Reverse("!oG ,olleH"))
+}
+</pre>
+
+<p>
+Whenever the <code>go</code> tool installs a package or binary, it also
+installs whatever dependencies it has.
+So when you install the <code>hello</code> program
+</p>
+
+<pre>
+$ <b>go install github.com/user/hello</b>
+</pre>
+
+<p>
+the <code>stringutil</code> package will be installed as well, automatically.
+</p>
+
+<p>
+Running the new version of the program, you should see a new, reversed message:
+</p>
+
+<pre>
+$ <b>hello</b>
+Hello, Go!
+</pre>
+
+<p>
+After the steps above, your workspace should look like this:
+</p>
+
+<pre>
+bin/
+    hello                 # command executable
+pkg/
+    linux_amd64/          # this will reflect your OS and architecture
+        github.com/user/
+            stringutil.a  # package object
+src/
+    github.com/user/
+        hello/
+            hello.go      # command source
+        stringutil/
+            reverse.go    # package source
+</pre>
+
+<p>
+Note that <code>go install</code> placed the <code>stringutil.a</code> object
+in a directory inside <code>pkg/linux_amd64</code> that mirrors its source
+directory.
+This is so that future invocations of the <code>go</code> tool can find the
+package object and avoid recompiling the package unnecessarily.
+The <code>linux_amd64</code> part is there to aid in cross-compilation,
+and will reflect the operating system and architecture of your system.
+</p>
+
+<p>
+Go command executables are statically linked; the package objects need not
+be present to run Go programs.
+</p>
+
+
+<h3 id="PackageNames">Package names</h3>
+
+<p>
+The first statement in a Go source file must be
+</p>
+
+<pre>
+package <i>name</i>
+</pre>
+
+<p>
+where <code><i>name</i></code> is the package's default name for imports.
+(All files in a package must use the same <code><i>name</i></code>.)
+</p>
+
+<p>
+Go's convention is that the package name is the last element of the
+import path: the package imported as "<code>crypto/rot13</code>"
+should be named <code>rot13</code>.
+</p>
+
+<p>
+Executable commands must always use <code>package main</code>.
+</p>
+
+<p>
+There is no requirement that package names be unique
+across all packages linked into a single binary,
+only that the import paths (their full file names) be unique.
+</p>
+
+<p>
+See <a href="/doc/effective_go.html#names">Effective Go</a> to learn more about
+Go's naming conventions.
+</p>
+
+
+<h2 id="Testing">Testing</h2>
+
+<p>
+Go has a lightweight test framework composed of the <code>go test</code>
+command and the <code>testing</code> package.
+</p>
+
+<p>
+You write a test by creating a file with a name ending in <code>_test.go</code>
+that contains functions named <code>TestXXX</code> with signature
+<code>func (t *testing.T)</code>.
+The test framework runs each such function;
+if the function calls a failure function such as <code>t.Error</code> or
+<code>t.Fail</code>, the test is considered to have failed.
+</p>
+
+<p>
+Add a test to the <code>stringutil</code> package by creating the file
+<code>$GOPATH/src/github.com/user/stringutil/reverse_test.go</code> containing
+the following Go code.
+</p>
+
+<pre>
+package stringutil
+
+import "testing"
+
+func TestReverse(t *testing.T) {

+}
+</pre>
+
+<p>
+Then run the test with <code>go test</code>:
+</p>
+
+<pre>
+$ <b>go test github.com/user/stringutil</b>
+ok  	github.com/user/stringutil 0.165s
+</pre>
+
+<p>
+As always, if you are running the <code>go</code> tool from the package
+directory, you can omit the package path:
+</p>
+
+<pre>
+$ <b>go test</b>
+ok  	github.com/user/stringutil 0.165s
+</pre>
+
+<p>
+Run <code><a href="/cmd/go/#hdr-Test_packages">go help test</a></code> and see the
+<a href="/pkg/testing/">testing package documentation</a> for more detail.
+</p>
+
+
+<h2 id="remote">Remote packages</h2>
+
+<p>
+An import path can describe how to obtain the package source code using a
+revision control system such as Git or Mercurial. The <code>go</code> tool uses
+this property to automatically fetch packages from remote repositories.
+For instance, the examples described in this document are also kept in a
+Git repository hosted at GitHub
+<code><a href="https://github.com/golang/example">github.com/golang/example</a></code>.
+If you include the repository URL in the package's import path,
+<code>go get</code> will fetch, build, and install it automatically:
+</p>
+
+<pre>
+$ <b>go get github.com/golang/example/hello</b>
+$ <b>$GOPATH/bin/hello</b>
+Hello, Go examples!
+</pre>
+
+<p>
+If the specified package is not present in a workspace, <code>go get</code>
+will place it inside the first workspace specified by <code>GOPATH</code>.
+(If the package does already exist, <code>go get</code> skips the remote
+fetch and behaves the same as <code>go install</code>.)
+</p>
+
+<p>
+After issuing the above <code>go get</code> command, the workspace directory
+tree should now look like this:
+</p>
+
+<pre>
+bin/
+    hello                           # command executable
+pkg/
+    linux_amd64/
+        github.com/golang/example/
+            stringutil.a            # package object
+        github.com/user/
+            stringutil.a            # package object
+src/
+    github.com/golang/example/
+	.git/                       # Git repository metadata
+        hello/
+            hello.go                # command source
+        stringutil/
+            reverse.go              # package source
+            reverse_test.go         # test source
+    github.com/user/
+        hello/
+            hello.go                # command source
+        stringutil/
+            reverse.go              # package source
+            reverse_test.go         # test source
+</pre>
+
+<p>
+The <code>hello</code> command hosted at GitHub depends on the
+<code>stringutil</code> package within the same repository. The imports in
+<code>hello.go</code> file use the same import path convention, so the
+<code>go get</code> command is able to locate and install the dependent
+package, too.
+</p>
+
+<pre>
+import "github.com/golang/example/stringutil"
+</pre>
+
+<p>
+This convention is the easiest way to make your Go packages available for
+others to use.
+The <a href="//golang.org/wiki/Projects">Go Wiki</a>
+and <a href="//godoc.org/">godoc.org</a>
+provide lists of external Go projects.

+<h2 id="about">About the Code of Conduct</h2>
+
+<h3 id="why">Why have a Code of Conduct?</h3>
+
+<p>
+Online communities include people from many different backgrounds.
+The Go contributors are committed to providing a friendly, safe and welcoming
+environment for all, regardless of age, disability, gender, nationality,
+ethnicity, religion, sexuality, or similar personal characteristic.
+</p>
+
+<p>
+The first goal of the Code of Conduct is to specify a baseline standard
+of behavior so that people with different social values and communication
+styles can talk about Go effectively, productively, and respectfully.
+</p>
+
+<p>
+The second goal is to provide a mechanism for resolving conflicts in the
+community when they arise.
+</p>
+
+<p>
+The third goal of the Code of Conduct is to make our community welcoming to
+people from different backgrounds.
+Diversity is critical to the project; for Go to be successful, it needs
+contributors and users from all backgrounds.
+(See <a href="https://blog.golang.org/open-source">Go, Open Source, Community</a>.)
+</p>
+
+<p>
+With that said, a healthy community must allow for disagreement and debate.
+The Code of Conduct is not a mechanism for people to silence others with whom
+they disagree.
+</p>
+
+<h3 id="spaces">Where does the Code of Conduct apply?</h3>
+
+<p>
+If you participate in or contribute to the Go ecosystem in any way,
+you are encouraged to follow the Code of Conduct while doing so.
+</p>
+
+<p>
+Explicit enforcement of the Code of Conduct applies to the
+official forums operated by the Go project (“Go spaces”):
+</p>
+
+<ul>
+    <li>The official <a href="https://github.com/golang/">GitHub projects</a>
+        and <a href="https://go-review.googlesource.com/">code reviews</a>.
+    <li>The <a href="https://groups.google.com/group/golang-nuts">golang-nuts</a> and
+        <a href="https://groups.google.com/group/golang-dev">golang-dev</a> mailing lists.
+<li>The #go-nuts IRC channel on Freenode.
+</ul>
+
+<p>
+Other Go groups (such as conferences, meetups, and other unofficial forums) are
+encouraged to adopt this Code of Conduct. Those groups must provide their own
+moderators and/or working group (see below).
+</p>
+
+<h2 id="values">Gopher values</h2>
+
+<p>
+These are the values to which people in the Go community (“Gophers”) should aspire.
+</p>
+
+<ul>
+<li>Be friendly and welcoming
+<li>Be patient
+    <ul>
+    <li>Remember that people have varying communication styles and that not
+        everyone is using their native language.
+        (Meaning and tone can be lost in translation.)
+    </ul>
+<li>Be thoughtful
+    <ul>
+    <li>Productive communication requires effort.
+        Think about how your words will be interpreted.
+    <li>Remember that sometimes it is best to refrain entirely from commenting.
+    </ul>
+<li>Be respectful
+    <ul>
+    <li>In particular, respect differences of opinion.
+    </ul>
+<li>Be charitable
+    <ul>
+    <li>Interpret the arguments of others in good faith, do not seek to disagree.
+    <li>When we do disagree, try to understand why.
+    </ul>
+<li>Avoid destructive behavior:
+    <ul>
+    <li>Derailing: stay on topic; if you want to talk about something else,
+        start a new conversation.
+    <li>Unconstructive criticism: don't merely decry the current state of affairs;
+        offer—or at least solicit—suggestions as to how things may be improved.
+    <li>Snarking (pithy, unproductive, sniping comments)
+    <li>Discussing potentially offensive or sensitive issues;
+        this all too often leads to unnecessary conflict.
+    <li>Microaggressions: brief and commonplace verbal, behavioral and
+        environmental indignities that communicate hostile, derogatory or negative
+        slights and insults to a person or group.
+    </ul>
+</ul>
+
+<p>
+People are complicated.
+You should expect to be misunderstood and to misunderstand others;
+when this inevitably occurs, resist the urge to be defensive or assign blame.
+Try not to take offense where no offense was intended.
+Give people the benefit of the doubt.
+Even if the intent was to provoke, do not rise to it.
+It is the responsibility of <i>all parties</i> to de-escalate conflict when it arises.
+</p>
+
+<h2 id="unwelcome_behavior">Unwelcome behavior</h2>
+
+<p>
+These actions are explicitly forbidden in Go spaces:
+</p>
+
+<ul>
+<li>Insulting, demeaning, hateful, or threatening remarks.
+<li>Discrimination based on age, disability, gender, nationality, race,
+    religion, sexuality, or similar personal characteristic.
+<li>Bullying or systematic harassment.
+<li>Unwelcome sexual advances.
+<li>Incitement to any of these.
+</ul>
+
+<h2 id="moderation">Moderation</h2>
+
+<p>
+The Go spaces are not free speech venues; they are for discussion about Go.
+Each of these spaces have their own moderators.
+</p>
+
+<p>
+When using the official Go spaces you should act in the spirit of the “Gopher
+values”.
+If a reported conflict cannot be resolved amicably, the CoC Working Group
+may make a recommendation to the relevant forum moderators.
+</p>
+
+<p>
+CoC Working Group members and forum moderators are held to a higher standard than other community members.
+If a working group member or moderator creates an inappropriate situation, they
+should expect less leeway than others, and should expect to be removed from
+their position if they cannot adhere to the CoC.
+</p>
+
+<p>
+Complaints about working group member or moderator actions must be handled 
+using the reporting process below.
+</p>
+
+<h2 id="reporting">Reporting issues</h2>
+
+<p>
+The Code of Conduct Working Group is a group of people that represent the Go
+community. They are responsible for handling conduct-related issues.
+Their purpose is to de-escalate conflicts and try to resolve issues to the
+satisfaction of all parties. They are:
+</p>
+
+<ul>
+	<li>Aditya Mukerjee &lt;dev@chimeracoder.net&gt;
+	<li>Andrew Gerrand &lt;adg@golang.org&gt;
+	<li>Peggy Li &lt;peggyli.224@gmail.com&gt;

+	<li>Steve Francia &lt;steve.francia@gmail.com&gt;
+	<li>Verónica López &lt;gveronicalg@gmail.com&gt;
+</ul>
+
+<p>
+If you encounter a conduct-related issue, you should report it to the
+Working Group using the process described below.
+<b>Do not</b> post about the issue publicly or try to rally sentiment against a
+particular individual or group.
+</p>
+
+<ul>
+<li>Mail <a href="mailto:conduct@golang.org">conduct@golang.org</a>.
+    <ul>
+    <li>Your message will reach the Working Group.
+    <li>Reports are confidential within the Working Group.
+    <li>You may contact a member of the group directly if you do not feel
+        comfortable contacting the group as a whole. That member will then raise
+        the issue with the Working Group as a whole, preserving the privacy of the
+        reporter (if desired).
+    <li>If your report concerns a member of the Working Group they will be recused
+        from Working Group discussions of the report.
+    <li>The Working Group will strive to handle reports with discretion and
+        sensitivity, to protect the privacy of the involved parties,
+        and to avoid conflicts of interest.
+    </ul>
+<li>You should receive a response within 48 hours (likely sooner).
+    (Should you choose to contact a single Working Group member,
+    it may take longer to receive a response.)
+<li>The Working Group will meet to review the incident and determine what happened.
+    <ul>
+    <li>With the permission of person reporting the incident, the Working Group
+        may reach out to other community members for more context.
+    </ul>
+<li>The Working Group will reach a decision as to how to act. These may include:
+    <ul>
+    <li>Nothing.
+    <li>Passing the report along to the offender.
+    <li>A recommendation of action to the relevant forum moderators.
+    </ul>
+<li>The Working Group will reach out to the original reporter to let them know
+    the decision.
+<li>Appeals to the decision may be made to the Working Group,
+    or to any of its members directly.
+</ul>
+
+<p>
+<b>Note that the goal of the Code of Conduct and the Working Group is to resolve
+conflicts in the most harmonious way possible.</b>
+We hope that in most cases issues may be resolved through polite discussion and
+mutual agreement.

+<h2 id="r60">r60 (released 2011/09/07)</h2>
+
+<p>
+The r60 release corresponds to 
+<code><a href="weekly.html#2011-08-17">weekly.2011-08-17</a></code>.
+This section highlights the most significant changes in this release.
+For a more detailed summary, see the
+<a href="weekly.html#2011-08-17">weekly release notes</a>.
+For complete information, see the
+<a href="//code.google.com/p/go/source/list?r=release-branch.r60">Mercurial change list</a>.
+</p>
+
+<h3 id="r60.lang">Language</h3>
+
+<p>
+An "else" block is now required to have braces except if the body of the "else"
+is another "if". Since gofmt always puts those braces in anyway,
+gofmt-formatted programs will not be affected.
+To fix other programs, run gofmt.
+</p>
+
+<h3 id="r60.pkg">Packages</h3>
+
+<p>
+<a href="/pkg/http/">Package http</a>'s URL parsing and query escaping code
+(such as <code>ParseURL</code> and <code>URLEscape</code>) has been moved to
+the new <a href="/pkg/url/">url package</a>, with several simplifications to
+the names. Client code can be updated automatically with gofix.
+</p>
+
+<p>
+<a href="/pkg/image/">Package image</a> has had significant changes made to the
+<code>Pix</code> field of struct types such as
+<a href="/pkg/image/#RGBA">image.RGBA</a> and
+<a href="/pkg/image/#NRGBA">image.NRGBA</a>.
+The <a href="/pkg/image/#Image">image.Image</a> interface type has not changed,
+though, and you should not need to change your code if you don't explicitly
+refer to <code>Pix</code> fields. For example, if you decode a number of images
+using the <a href="/pkg/image/jpeg/">image/jpeg</a> package, compose them using
+<a href="/pkg/image/draw/">image/draw</a>, and then encode the result using
+<a href="/pkg/img/png">image/png</a>, then your code should still work as
+before.
+If your code <i>does</i> refer to <code>Pix</code> fields see the 
+<a href="/doc/devel/weekly.html#2011-07-19">weekly.2011-07-19</a>
+snapshot notes for how to update your code.
+</p>
+
+<p>
+<a href="/pkg/template/">Package template</a> has been replaced with a new
+templating package (formerly <code>exp/template</code>). The original template
+package is still available as <a href="/pkg/old/template/">old/template</a>.
+The <code>old/template</code> package is deprecated and will be removed.
+The Go tree has been updated to use the new template package. We encourage
+users of the old template package to switch to the new one. Code that uses
+<code>template</code> or <code>exp/template</code> will need to change its
+import lines to <code>"old/template"</code> or <code>"template"</code>,
+respectively.
+</p>
+
+<h3 id="r60.cmd">Tools</h3>
+
+<p>
+<a href="/cmd/goinstall/">Goinstall</a> now uses a new tag selection scheme.
+When downloading or updating, goinstall looks for a tag or branch with the
+<code>"go."</code> prefix that corresponds to the local Go version. For Go
+<code>release.r58</code> it looks for <code>go.r58</code>. For
+<code>weekly.2011-06-03</code> it looks for <code>go.weekly.2011-06-03</code>.
+If the specific <code>go.X</code> tag or branch is not found, it chooses the
+closest earlier version. If an appropriate tag or branch is found, goinstall
+uses that version of the code. Otherwise it uses the default version selected
+by the version control system. Library authors are encouraged to use the
+appropriate tag or branch names in their repositories to make their libraries
+more accessible.

+<p>
+This release includes a language change that restricts the use of
+<code>goto</code>.  In essence, a <code>goto</code> statement outside a block
+cannot jump to a label inside that block. Your code may require changes if it
+uses <code>goto</code>.
+See <a href="//golang.org/change/dc6d3cf9279d">this
+changeset</a> for how the new rule affected the Go tree.
+</p>
+
+<h3 id="r59.pkg">Packages</h3>
+
+<p>
+As usual, <a href="/cmd/gofix/">gofix</a> will handle the bulk of the rewrites
+necessary for these changes to package APIs.
+</p>
+
+<p>
+<a href="/pkg/http">Package http</a> has a new
+<a href="/pkg/http/#FileSystem">FileSystem</a> interface that provides access
+to files. The <a href="/pkg/http/#FileServer">FileServer</a> helper now takes a
+<code>FileSystem</code> argument instead of an explicit file system root. By
+implementing your own <code>FileSystem</code> you can use the
+<code>FileServer</code> to serve arbitrary data.
+</p>
+
+<p>
+<a href="/pkg/os/">Package os</a>'s <code>ErrorString</code> type has been
+hidden. Most uses of <code>os.ErrorString</code> can be replaced with
+<a href="/pkg/os/#NewError">os.NewError</a>.
+</p>
+
+<p>
+<a href="/pkg/reflect/">Package reflect</a> supports a new struct tag scheme
+that enables sharing of struct tags between multiple packages.
+In this scheme, the tags must be of the form:
+</p>
+<pre>
+	`key:"value" key2:"value2"`
+</pre>
+<p>
+The <a href="/pkg/reflect/#StructField">StructField</a> type's Tag field now
+has type <a href="/pkg/reflect/#StructTag">StructTag</a>, which has a
+<code>Get</code> method. Clients of <a href="/pkg/json">json</a> and
+<a href="/pkg/xml">xml</a> will need to be updated. Code that says
+</p>
+<pre>
+	type T struct {
+		X int "name"
+	}
+</pre>
+<p>
+should become
+</p>
+<pre>

+	}
+</pre>
+<p>
+Use <a href="/cmd/govet/">govet</a> to identify struct tags that need to be

+<a href="/pkg/sort/">Package sort</a>'s <code>IntArray</code> type has been
+renamed to <a href="/pkg/sort/#IntSlice">IntSlice</a>, and similarly for
+<a href="/pkg/sort/#Float64Slice">Float64Slice</a> and
+<a href="/pkg/sort/#StringSlice">StringSlice</a>.
+</p>
+
+<p>
+<a href="/pkg/strings/">Package strings</a>'s <code>Split</code> function has
+itself been split into <a href="/pkg/strings/#Split">Split</a> and
+<a href="/pkg/strings/#SplitN">SplitN</a>.
+<code>SplitN</code> is the same as the old <code>Split</code>.
+The new <code>Split</code> is equivalent to <code>SplitN</code> with a final
+argument of -1.
+</p>
+
+<a href="/pkg/image/draw/">Package image/draw</a>'s
+<a href="/pkg/image/draw/#Draw">Draw</a> function now takes an additional
+argument, a compositing operator.
+If in doubt, use <a href="/pkg/image/draw/#Op">draw.Over</a>.
+</p>
+
+<h3 id="r59.cmd">Tools</h3>
+
+<p>
+<a href="/cmd/goinstall/">Goinstall</a> now installs packages and commands from

+
+<h2 id="r58">r58 (released 2011/06/29)</h2>

+</p>
+
+<p>
+<a href="/pkg/exec/">Package exec</a> has been redesigned with a more

+</p>
+
+<p>
+<a href="/pkg/strconv/">Package strconv</a>'s <a href="/pkg/strconv/#Quote">Quote</a>
+function now escapes only those Unicode code points not classified as printable
+by <a href="/pkg/unicode/#IsPrint">unicode.IsPrint</a>.
+Previously Quote would escape all non-ASCII characters.
+This also affects the <a href="/pkg/fmt/">fmt</a> package's <code>"%q"</code>

+<a href="/pkg/gob/#GobEncoder">GobEncoder</a> and
+<a href="/pkg/gob/#GobDecoder">GobDecoder</a> interfaces. This allows types with unexported

+</p>
+
+<p>
+<a href="/pkg/http/">Package http</a> has been redesigned.
+For clients, there are new
+<a href="/pkg/http/#Client">Client</a> and <a href="/pkg/http/#Transport">Transport</a>
+abstractions that give more control over HTTP details such as headers sent
+and redirections followed.  These abstractions make it easy to implement
+custom clients that add functionality such as <a href="//code.google.com/p/goauth2/source/browse/oauth/oauth.go">OAuth2</a>.
+For servers, <a href="/pkg/http/#ResponseWriter">ResponseWriter</a>
+has dropped its non-essential methods.
+The Hijack and Flush methods are no longer required;
+code can test for them by checking whether a specific value implements
+<a href="/pkg/http/#Hijacker">Hijacker</a> or <a href="/pkg/http/#Flusher">Flusher</a>.
+The RemoteAddr and UsingTLS methods are replaced by <a href="/pkg/http/#Request">Request</a>'s
+RemoteAddr and TLS fields.
+The SetHeader method is replaced by a Header method;
+its result, of type <a href="/pkg/http/#Header">Header</a>,
+implements Set and other methods.
+</p>
+
+<p>
+<a href="/pkg/net/">Package net</a>
+drops the <code>laddr</code> argument from <a href="/pkg/net/#Conn.Dial">Dial</a>
+and drops the <code>cname</code> return value
+from <a href="/pkg/net/#LookupHost">LookupHost</a>.
+The implementation now uses <a href="/cmd/cgo/">cgo</a> to implement
+network name lookups using the C library getaddrinfo(3)
+function when possible.  This ensures that Go and C programs
+resolve names the same way and also avoids the OS X 
+application-level firewall.
+</p>
+
+<p>
+<a href="/pkg/os/">Package os</a>
+introduces simplified <a href="/pkg/os/#File.Open">Open</a>

+The final three arguments to <a href="/pkg/os/#Process.StartProcess">StartProcess</a>
+have been replaced by a pointer to a <a href="/pkg/os/#ProcAttr">ProcAttr</a>.
+</p>
+
+<p>
+<a href="/pkg/reflect/">Package reflect</a> has been redesigned.
+<a href="/pkg/reflect/#Type">Type</a> is now an interface that implements
+all the possible type methods.
+Instead of a type switch on a Type <code>t</code>, switch on <code>t.Kind()</code>.
+<a href="/pkg/reflect/#Value">Value</a> is now a struct value that
+implements all the possible value methods.
+Instead of a type switch on a Value <code>v</code>, switch on <code>v.Kind()</code>.
+Typeof and NewValue are now called <a href="/pkg/reflect/#Type.TypeOf">TypeOf</a> and <a href="/pkg/reflect/#Value.ValueOf">ValueOf</a>
+To create a writable Value, use <code>New(t).Elem()</code> instead of <code>Zero(t)</code>.
+See <a href="//golang.org/change/843855f3c026">the change description</a>
+for the full details.
+The new API allows a more efficient implementation of Value
+that avoids many of the allocations required by the previous API.

+<p>This page summarizes the changes between official stable releases of Go.
+The <a href="//golang.org/change">change log</a> has the full details.</p>
+
+<p>To update to a specific release, use:</p>
+
+<pre>
+git pull
+git checkout <i>release-branch</i>
+</pre>
+
+<h2 id="policy">Release Policy</h2>
+
+<p>
+Each major Go release obsoletes and ends support for the previous one.
+For example, if Go 1.5 has been released, then it is the current release
+and Go 1.4 and earlier are no longer supported.
+We fix critical problems in the current release as needed by issuing minor revisions
+(for example, Go 1.5.1, Go 1.5.2, and so on).
+</p>
+
+<p>
+As a special case, we issue minor revisions for critical security problems
+in both the current release and the previous release.
+For example, if Go 1.5 is the current release then we will issue minor revisions
+to fix critical security problems in both Go 1.4 and Go 1.5 as they arise.
+See the <a href="/security">security policy</a> for more details.

-<h2 id="introduction">Introduction</h2>
-
-<p>
-The Go ecosystem provides a large suite of APIs and tools to
-diagnose logic and performance problems in Go programs. This page
-summarizes the available tools and helps Go users pick the right one
-for their specific problem.
-</p>
-
-<p>
-Diagnostics solutions can be categorized into the following groups:
-</p>
-
-<ul>
-<li><strong>Profiling</strong>: Profiling tools analyze the complexity and costs of a
-Go program such as its memory usage and frequently called
-functions to identify the expensive sections of a Go program.</li>
-<li><strong>Tracing</strong>: Tracing is a way to instrument code to analyze latency
-throughout the lifecycle of a call or user request. Traces provide an
-overview of how much latency each component contributes to the overall
-latency in a system. Traces can span multiple Go processes.</li>
-<li><strong>Debugging</strong>: Debugging allows us to pause a Go program and examine
-its execution. Program state and flow can be verified with debugging.</li>
-<li><strong>Runtime statistics and events</strong>: Collection and analysis of runtime stats and events
-provides a high-level overview of the health of Go programs. Spikes/dips of metrics
-helps us to identify changes in throughput, utilization, and performance.</li>
-</ul>
-
-<p>
-Note: Some diagnostics tools may interfere with each other. For example, precise
-memory profiling skews CPU profiles and goroutine blocking profiling affects scheduler
-trace. Use tools in isolation to get more precise info.
-</p>
-
-<h2 id="profiling">Profiling</h2>
-
-<p>
-Profiling is useful for identifying expensive or frequently called sections
-of code. The Go runtime provides <a href="https://golang.org/pkg/runtime/pprof/">
-profiling data</a> in the format expected by the
-<a href="https://github.com/google/pprof/blob/master/doc/README.md">pprof visualization tool</a>.
-The profiling data can be collected during testing
-via <code>go</code> <code>test</code> or endpoints made available from the <a href="/pkg/net/http/pprof/">
-net/http/pprof</a> package. Users need to collect the profiling data and use pprof tools to filter
-and visualize the top code paths.
-</p>
-
-<p>Predefined profiles provided by the <a href="/pkg/runtime/pprof">runtime/pprof</a> package:</p>
-
-<ul>
-<li>
-<strong>cpu</strong>: CPU profile determines where a program spends
-its time while actively consuming CPU cycles (as opposed to while sleeping or waiting for I/O).
-</li>
-<li>
-<strong>heap</strong>: Heap profile reports memory allocation samples;
-used to monitor current and historical memory usage, and to check for memory leaks.
-</li>
-<li>
-<strong>threadcreate</strong>: Thread creation profile reports the sections
-of the program that lead the creation of new OS threads.
-</li>
-<li>
-<strong>goroutine</strong>: Goroutine profile reports the stack traces of all current goroutines.
-</li>
-<li>
-<strong>block</strong>: Block profile shows where goroutines block waiting on synchronization
-primitives (including timer channels). Block profile is not enabled by default;
-use <code>runtime.SetBlockProfileRate</code> to enable it.
-</li>
-<li>
-<strong>mutex</strong>: Mutex profile reports the lock contentions. When you think your
-CPU is not fully utilized due to a mutex contention, use this profile. Mutex profile
-is not enabled by default, see <code>runtime.SetMutexProfileFraction</code> to enable it.
-</li>
-</ul>
-
-
-<p><strong>What other profilers can I use to profile Go programs?</strong></p>
-
-<p>
-On Linux, <a href="https://perf.wiki.kernel.org/index.php/Tutorial">perf tools</a>
-can be used for profiling Go programs. Perf can profile
-and unwind cgo/SWIG code and kernel, so it can be useful to get insights into
-native/kernel performance bottlenecks. On macOS,
-<a href="https://developer.apple.com/library/content/documentation/DeveloperTools/Conceptual/InstrumentsUserGuide/">Instruments</a>
-suite can be used profile Go programs.
-</p>
-
-<p><strong>Can I profile my production services?</strong></p>
-
-<p>Yes. It is safe to profile programs in production, but enabling
-some profiles (e.g. the CPU profile) adds cost. You should expect to
-see performance downgrade. The performance penalty can be estimated
-by measuring the overhead of the profiler before turning it on in
-production.
-</p>
-
-<p>
-You may want to periodically profile your production services.
-Especially in a system with many replicas of a single process, selecting
-a random replica periodically is a safe option.
-Select a production process, profile it for
-X seconds for every Y seconds and save the results for visualization and
-analysis; then repeat periodically. Results may be manually and/or automatically
-reviewed to find problems.
-Collection of profiles can interfere with each other,
-so it is recommended to collect only a single profile at a time.
-</p>
-
-<p>
-<strong>What are the best ways to visualize the profiling data?</strong>
-</p>
-
-<p>
-The Go tools provide text, graph, and <a href="http://valgrind.org/docs/manual/cl-manual.html">callgrind</a>
-visualization of the profile data using
-<code><a href="https://github.com/google/pprof/blob/master/doc/README.md">go tool pprof</a></code>.
-Read <a href="https://blog.golang.org/profiling-go-programs">Profiling Go programs</a>
-to see them in action.

-
-<p>
-Another way to visualize profile data is a <a href="http://www.brendangregg.com/flamegraphs.html">flame graph</a>.
-Flame graphs allow you to move in a specific ancestry path, so you can zoom
-in/out of specific sections of code.
-The <a href="https://github.com/google/pprof">upstream pprof</a>
-has support for flame graphs.

-</p>
-
-<p><strong>Am I restricted to the built-in profiles?</strong></p>
-
-<p>
-Additionally to what is provided by the runtime, Go users can create
-their custom profiles via <a href="/pkg/runtime/pprof/#Profile">pprof.Profile</a>
-and use the existing tools to examine them.
-</p>
-
-<p><strong>Can I serve the profiler handlers (/debug/pprof/...) on a different path and port?</strong></p>
-
-<p>
-Yes. The <code>net/http/pprof</code> package registers its handlers to the default
-mux by default, but you can also register them yourself by using the handlers
-exported from the package.
-</p>
-
-<p>
-For example, the following example will serve the pprof.Profile
-handler on :7777 at /custom_debug_path/profile:
-</p>
-
-<p>
-<pre>
-package main
-
-import (
-	"log"
-	"net/http"
-	"net/http/pprof"
-)
-
-func main() {
-	mux := http.NewServeMux()
-	mux.HandleFunc("/custom_debug_path/profile", pprof.Profile)
-	log.Fatal(http.ListenAndServe(":7777", mux))

-<h2 id="tracing">Tracing</h2>
-
-<p>
-Tracing is a way to instrument code to analyze latency throughout the
-lifecycle of a chain of calls. Go provides
-<a href="https://godoc.org/golang.org/x/net/trace">golang.org/x/net/trace</a>
-package as a minimal tracing backend per Go node and provides a minimal
-instrumentation library with a simple dashboard. Go also provides
-an execution tracer to trace the runtime events within an interval.
-</p>
-
-<p>Tracing enables us to:</p>
-
-<ul>
-<li>Instrument and analyze application latency in a Go process.</li>
-<li>Measure the cost of specific calls in a long chain of calls.</li>
-<li>Figure out the utilization and performance improvements.
-Bottlenecks are not always obvious without tracing data.</li>
-</ul>
-
-<p>
-In monolithic systems, it's relatively easy to collect diagnostic data
-from the building blocks of a program. All modules live within one
-process and share common resources to report logs, errors, and other
-diagnostic information. Once your system grows beyond a single process and
-starts to become distributed, it becomes harder to follow a call starting
-from the front-end web server to all of its back-ends until a response is
-returned back to the user. This is where distributed tracing plays a big
-role to instrument and analyze your production systems.
-</p>
-
-<p>
-Distributed tracing is a way to instrument code to analyze latency throughout
-the lifecycle of a user request. When a system is distributed and when
-conventional profiling and debugging tools don’t scale, you might want
-to use distributed tracing tools to analyze the performance of your user
-requests and RPCs.

-<p>Distributed tracing enables us to:</p>
-
-<ul>
-<li>Instrument and profile application latency in a large system.</li>
-<li>Track all RPCs within the lifecycle of a user request and see integration issues
-that are only visible in production.</li>
-<li>Figure out performance improvements that can be applied to our systems.
-Many bottlenecks are not obvious before the collection of tracing data.</li>
-</ul>
-
-<p>The Go ecosystem provides various distributed tracing libraries per tracing system
-and backend-agnostic ones.</p>
-
-
-<p><strong>Is there a way to automatically intercept each function call and create traces?</strong></p>
-
-<p>
-Go doesn’t provide a way to automatically intercept every function call and create
-trace spans. You need to manually instrument your code to create, end, and annotate spans.
-</p>
-
-<p><strong>How should I propagate trace headers in Go libraries?</strong></p>
-
-<p>
-You can propagate trace identifiers and tags in the
-<a href="/pkg/context#Context"><code>context.Context</code></a>.
-There is no canonical trace key or common representation of trace headers
-in the industry yet. Each tracing provider is responsible for providing propagation
-utilities in their Go libraries.
-</p>
-
-<p>
-<strong>What other low-level events from the standard library or
-runtime can be included in a trace?</strong>
-</p>
-
-<p>
-The standard library and runtime are trying to expose several additional APIs
-to notify on low level internal events. For example,
-<a href="/pkg/net/http/httptrace#ClientTrace"><code>httptrace.ClientTrace</code></a>
-provides APIs to follow low-level events in the life cycle of an outgoing request.
-There is an ongoing effort to retrieve low-level runtime events from
-the runtime execution tracer and allow users to define and record their user events.
-</p>
-
-<h2 id="debugging">Debugging</h2>
-
-<p>
-Debugging is the process of identifying why a program misbehaves.
-Debuggers allow us to understand a program’s execution flow and current state.
-There are several styles of debugging; this section will only focus on attaching
-a debugger to a program and core dump debugging.
-</p>
-
-<p>Go users mostly use the following debuggers:</p>
-
-<ul>
-<li>
-<a href="https://github.com/derekparker/delve">Delve</a>:
-Delve is a debugger for the Go programming language. It has
-support for Go’s runtime concepts and built-in types. Delve is
-trying to be a fully featured reliable debugger for Go programs.
-</li>
-<li>
-<a href="https://golang.org/doc/gdb">GDB</a>:
-Go provides GDB support via the standard Go compiler and Gccgo.
-The stack management, threading, and runtime contain aspects that differ
-enough from the execution model GDB expects that they can confuse the
-debugger, even when the program is compiled with gccgo. Even though
-GDB can be used to debug Go programs, it is not ideal and may
-create confusion.
-</li>
-</ul>
-
-<p><strong>How well do debuggers work with Go programs?</strong></p>
-
-<p>
-The <code>gc</code> compiler performs optimizations such as
-function inlining and variable registerization. These optimizations
-sometimes make debugging with debuggers harder. There is an ongoing
-effort to improve the quality of the DWARF information generated for
-optimized binaries. Until those improvements are available, we recommend
-disabling optimizations when building the code being debugged. The following
-command builds a package with no compiler optimizations:
-
-<p>
-<pre>
-$ go build -gcflags=all="-N -l"
-</pre>
-</p>
-
-As part of the improvement effort, Go 1.10 introduced a new compiler
-flag <code>-dwarflocationlists</code>. The flag causes the compiler to
-add location lists that helps debuggers work with optimized binaries.
-The following command builds a package with optimizations but with
-the DWARF location lists:
-
-<p>
-<pre>
-$ go build -gcflags="-dwarflocationlists=true"
-</pre>
-</p>
-
-<p><strong>What’s the recommended debugger user interface?</strong></p>
-
-<p>
-Even though both delve and gdb provides CLIs, most editor integrations
-and IDEs provides debugging-specific user interfaces.
-</p>
-
-<p><strong>Is it possible to do postmortem debugging with Go programs?</strong></p>
-
-<p>
-A core dump file is a file that contains the memory dump of a running
-process and its process status. It is primarily used for post-mortem
-debugging of a program and to understand its state
-while it is still running. These two cases make debugging of core
-dumps a good diagnostic aid to postmortem and analyze production
-services. It is possible to obtain core files from Go programs and
-use delve or gdb to debug, see the
-<a href="https://golang.org/wiki/CoreDumpDebugging">core dump debugging</a>
-page for a step-by-step guide.
-</p>
-
-<h2 id="runtime">Runtime statistics and events</h2>
-
-<p>
-The runtime provides stats and reporting of internal events for
-users to diagnose performance and utilization problems at the
-runtime level.
-</p>
-
-<p>
-Users can monitor these stats to better understand the overall
-health and performance of Go programs.
-Some frequently monitored stats and states:
-</p>
-
-<ul>
-<li><code><a href="/pkg/runtime/#ReadMemStats">runtime.ReadMemStats</a></code>
-reports the metrics related to heap
-allocation and garbage collection. Memory stats are useful for
-monitoring how much memory resources a process is consuming,
-whether the process can utilize memory well, and to catch
-memory leaks.</li>
-<li><code><a href="/pkg/runtime/debug/#ReadGCStats">debug.ReadGCStats</a></code>
-reads statistics about garbage collection.
-It is useful to see how much of the resources are spent on GC pauses.
-It also reports a timeline of garbage collector pauses and pause time percentiles.</li>
-<li><code><a href="/pkg/runtime/debug/#Stack">debug.Stack</a></code>
-returns the current stack trace. Stack trace
-is useful to see how many goroutines are currently running,
-what they are doing, and whether they are blocked or not.</li>
-<li><code><a href="/pkg/runtime/debug/#WriteHeapDump">debug.WriteHeapDump</a></code>
-suspends the execution of all goroutines
-and allows you to dump the heap to a file. A heap dump is a
-snapshot of a Go process' memory at a given time. It contains all
-allocated objects as well as goroutines, finalizers, and more.</li>
-<li><code><a href="/pkg/runtime#NumGoroutine">runtime.NumGoroutine</a></code>
-returns the number of current goroutines.
-The value can be monitored to see whether enough goroutines are
-utilized, or to detect goroutine leaks.</li>
-</ul>
-
-<h3 id="execution-tracer">Execution tracer</h3>
-
-<p>Go comes with a runtime execution tracer to capture a wide range
-of runtime events. Scheduling, syscall, garbage collections,
-heap size, and other events are collected by runtime and available
-for visualization by the go tool trace. Execution tracer is a tool
-to detect latency and utilization problems. You can examine how well
-the CPU is utilized, and when networking or syscalls are a cause of
-preemption for the goroutines.</p>
-
-<p>Tracer is useful to:</p>
-<ul>
-<li>Understand how your goroutines execute.</li>
-<li>Understand some of the core runtime events such as GC runs.</li>
-<li>Identify poorly parallelized execution.</li>
-</ul>
-
-<p>However, it is not great for identifying hot spots such as
-analyzing the cause of excessive memory or CPU usage.
-Use profiling tools instead first to address them.</p>
-
-<p>
-<img width="800" src="https://storage.googleapis.com/golangorg-assets/tracer-lock.png">
-</p>
-
-<p>Above, the go tool trace visualization shows the execution started
-fine, and then it became serialized. It suggests that there might
-be lock contention for a shared resource that creates a bottleneck.</p>
-
-<p>See <a href="https://golang.org/cmd/trace/"><code>go</code> <code>tool</code> <code>trace</code></a>
-to collect and analyze runtime traces.
-</p>
-
-<h3 id="godebug">GODEBUG</h3>
-
-<p>Runtime also emits events and information if
-<a href="https://golang.org/pkg/runtime/#hdr-Environment_Variables">GODEBUG</a>
-environmental variable is set accordingly.</p>
-
-<ul>
-<li>GODEBUG=gctrace=1 prints garbage collector events at
-each collection, summarizing the amount of memory collected
-and the length of the pause.</li>
-<li>GODEBUG=schedtrace=X prints scheduling events every X milliseconds.</li>
-</ul>
-
-<p>The GODEBUG environmental variable can be used to disable use of
-instruction set extensions in the standard library and runtime.</p>
-
-<ul>
-<li>GODEBUG=cpu.all=off disables the use of all optional
-instruction set extensions.</li>
-<li>GODEBUG=cpu.<em>extension</em>=off disables use of instructions from the
-specified instruction set extension.<br>
-<em>extension</em> is the lower case name for the instruction set extension
-such as <em>sse41</em> or <em>avx</em>.</li>

+The Go programming language is an open source project to make programmers more
+productive.
+</p>
+
+<p>
+Go is expressive, concise, clean, and efficient. Its concurrency
+mechanisms make it easy to write programs that get the most out of multicore
+and networked machines, while its novel type system enables flexible and
+modular program construction. Go compiles quickly to machine code yet has the
+convenience of garbage collection and the power of run-time reflection. It's a
+fast, statically typed, compiled language that feels like a dynamically typed,
+interpreted language.

-  Go 1.11 adds preliminary support for a <a href="/cmd/go/#hdr-Modules__module_versions__and_more">new concept called “modules,”</a>
-  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

-<h3 id="gopackages">Package loading</h3>
-
-<p>
-  The new package
-  <a href="https://godoc.org/golang.org/x/tools/go/packages"><code>golang.org/x/tools/go/packages</code></a>
-  provides a simple API for locating and loading packages of Go source code.
-  Although not yet part of the standard library, for many tasks it
-  effectively replaces the <a href="/pkg/go/build"><code>go/build</code></a>
-  package, whose API is unable to fully support modules.
-  Because it runs an external query command such as
-  <a href="/cmd/go/#hdr-List_packages"><code>go list</code></a>
-  to obtain information about Go packages, it enables the construction of
-  analysis tools that work equally well with alternative build systems
-  such as <a href="https://bazel.build">Bazel</a>
-  and <a href="https://buckbuild.com">Buck</a>.
-</p>
-
-<h3 id="gocache">Build cache requirement</h3>
-
-<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.

-<h3 id="compiler">Compiler toolchain</h3>
-
-<p><!-- CL 109918 -->
-  More functions are now eligible for inlining by default, including
-  functions that call <code>panic</code>.
-</p>
-
-<p><!-- CL 97375 -->
-  The compiler toolchain now supports column information
-  in <a href="/cmd/compile/#hdr-Compiler_Directives">line
-  directives</a>.
-</p>
-
-<p><!-- CL 106797 -->
-  A new package export data format has been introduced.
-  This should be transparent to end users, except for speeding up
-  build times for large Go projects.
-  If it does cause problems, it can be turned off again by
-  passing <code>-gcflags=all=-iexport=false</code> to
-  the <code>go</code> tool when building a binary.
-</p>
-
-<p><!-- CL 100459 -->
-  The compiler now rejects unused variables declared in a type switch
-  guard, such as <code>x</code> in the following example:
-</p>
-<pre>
-func f(v interface{}) {
-	switch x := v.(type) {
-	}
-}
-</pre>
-<p>
-  This was already rejected by both <code>gccgo</code>
-  and <a href="/pkg/go/types/">go/types</a>.
-</p>
-
-<h3 id="assembler">Assembler</h3>
-
-<p><!-- CL 113315 -->
-  The assembler for <code>amd64</code> now accepts AVX512 instructions.
-</p>
-
-<h3 id="debugging">Debugging</h3>
-
-<p><!-- CL 100738, CL 93664 -->
-  The compiler now produces significantly more accurate debug
-  information for optimized binaries, including variable location
-  information, line numbers, and breakpoint locations.
-
-  This should make it possible to debug binaries
-  compiled <em>without</em> <code>-N</code>&nbsp;<code>-l</code>.
-
-  There are still limitations to the quality of the debug information,
-  some of which are fundamental, and some of which will continue to
-  improve with future releases.
-</p>
-
-<p><!-- CL 118276 -->
-  DWARF sections are now compressed by default because of the expanded
-  and more accurate debug information produced by the compiler.
-
-  This is transparent to most ELF tools (such as debuggers on Linux
-  and *BSD) and is supported by the Delve debugger on all platforms,
-  but has limited support in the native tools on macOS and Windows.
-
-  To disable DWARF compression,
-  pass <code>-ldflags=-compressdwarf=false</code> to
-  the <code>go</code> tool when building a binary.
-</p>
-
-<p><!-- CL 109699 -->
-  Go 1.11 adds experimental support for calling Go functions from
-  within a debugger.
-
-  This is useful, for example, to call <code>String</code> methods
-  when paused at a breakpoint.
-
-  This is currently only supported by Delve (version 1.1.0 and up).
-</p>
-
-<h3 id="test">Test</h3>
-
-<p>
-  Since Go 1.10, the <code>go</code>&nbsp;<code>test</code> command runs
-  <code>go</code>&nbsp;<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 Go 1.10, 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>
-
-<p><!-- CL 102696 -->
-  The <code>-memprofile</code> flag
-  to <code>go</code>&nbsp;<code>test</code> now defaults to the
-  "allocs" profile, which records the total bytes allocated since the
-  test began (including garbage-collected bytes).
-</p>
-
-<h3 id="vet">Vet</h3>
-
-<p><!-- CL 108555 -->
-  The <a href="/cmd/vet/"><code>go</code>&nbsp;<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>
-
-<p><!-- CL 108559 -->
-  Additionally, <a href="/cmd/vet"><code>go</code>&nbsp;<code>vet</code></a>
-  has become more robust when format-checking <code>printf</code> wrappers.
-  Vet now detects the mistake in this example:
-</p>
-
-<pre>
-func wrapper(s string, args ...interface{}) {
-	fmt.Printf(s, args...)
-}
-
-func main() {
-	wrapper("%s", 42)
-}
-</pre>
-
-<h3 id="trace">Trace</h3>
-
-<p><!-- CL 63274 -->
-  With the new <code>runtime/trace</code>
-  package's <a href="/pkg/runtime/trace/#hdr-User_annotation">user
-  annotation API</a>, users can record application-level information
-  in execution traces and create groups of related goroutines.
-  The <code>go</code>&nbsp;<code>tool</code>&nbsp;<code>trace</code>
-  command visualizes this information in the trace view and the new
-  user task/region analysis page.
-</p>
-
-<h3 id="cgo">Cgo</h3>
-
-<p>
-Since Go 1.10, cgo has translated some C pointer types to the Go
-type <code>uintptr</code>. These types include
-the <code>CFTypeRef</code> hierarchy in Darwin's CoreFoundation
-framework and the <code>jobject</code> hierarchy in Java's JNI
-interface. In Go 1.11, several improvements have been made to the code
-that detects these types. Code that uses these types may need some
-updating. See the <a href="go1.10.html#cgo">Go 1.10 release notes</a> for
-details. <!-- CL 126275, CL 127156, CL 122217, CL 122575, CL 123177 -->
-</p>
-
-<h3 id="go_command">Go command</h3>
-
-<p><!-- CL 126656 -->
-  The environment variable <code>GOFLAGS</code> may now be used
-  to set default flags for the <code>go</code> command.
-  This is useful in certain situations.
-  Linking can be noticeably slower on underpowered systems due to DWARF,
-  and users may want to set <code>-ldflags=-w</code> by default.
-  For modules, some users and CI systems will want vendoring always,
-  so they should set <code>-mod=vendor</code> by default.
-  For more information, see the <a href="/cmd/go/#hdr-Environment_variables"><code>go</code>
-  command documentation</a>.
-</p>
-
-<h3 id="godoc">Godoc</h3>
-
-<p>
-  Go 1.11 will be the last release to support <code>godoc</code>'s command-line interface.
-  In future releases, <code>godoc</code> will only be a web server. Users should use
-  <code>go</code> <code>doc</code> for command-line help output instead.
-</p>
-
-<p><!-- CL 85396, CL 124495 -->
-  The <code>godoc</code> web server now shows which version of Go introduced
-  new API features. The initial Go version of types, funcs, and methods are shown
-  right-aligned. For example, see <a href="/pkg/os/#UserCacheDir"><code>UserCacheDir</code></a>, with "1.11"
-  on the right side. For struct fields, inline comments are added when the struct field was
-  added in a Go version other than when the type itself was introduced.
-  For a struct field example, see
-  <a href="/pkg/net/http/httptrace/#ClientTrace.Got1xxResponse"><code>ClientTrace.Got1xxResponse</code></a>.
-</p>
-
-<h3 id="gofmt">Gofmt</h3>
-
-<p>
-  One minor detail of the default formatting of Go source code has changed.
-  When formatting expression lists with inline comments, the comments were
-  aligned according to a heuristic.
-  However, in some cases the alignment would be split up too easily, or
-  introduce too much whitespace.
-  The heuristic has been changed to behave better for human-written code.
-</p>
-
-<p>
-  Note that these kinds of minor updates to gofmt are expected from time to
-  time.
-  In general, systems that need consistent formatting of Go source code should
-  use a specific version of the <code>gofmt</code> binary.
-  See the <a href="/pkg/go/format/">go/format</a> package documentation for more
-  information.
-</p>
-
-<h3 id="run">Run</h3>
-
-<p>
-  <!-- CL 109341 -->
-  The <a href="/cmd/go/"><code>go</code>&nbsp;<code>run</code></a>
-  command now allows a single import path, a directory name or a
-  pattern matching a single package.
-  This allows <code>go</code>&nbsp;<code>run</code>&nbsp;<code>pkg</code> or <code>go</code>&nbsp;<code>run</code>&nbsp;<code>dir</code>, most importantly <code>go</code>&nbsp;<code>run</code>&nbsp;<code>.</code>
-</p>
-
-<h2 id="runtime">Runtime</h2>
-
-<p><!-- CL 85887 -->
-  The runtime now uses a sparse heap layout so there is no longer a
-  limit to the size of the Go heap (previously, the limit was 512GiB).
-  This also fixes rare "address space conflict" failures in mixed Go/C
-  binaries or binaries compiled with <code>-race</code>.
-</p>
-
-<p><!-- CL 108679, CL 106156 -->
-  On macOS and iOS, the runtime now uses <code>libSystem.dylib</code> instead of
-  calling the kernel directly. This should make Go binaries more
-  compatible with future versions of macOS and iOS.
-  The <a href="/pkg/syscall">syscall</a> package still makes direct
-  system calls; fixing this is planned for a future release.
-</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 better generated code and
-optimizations in the core library.
-</p>
-
-<p><!-- CL 74851 -->
-There were multiple performance changes to the <code>math/big</code>
-package as well as many changes across the tree specific to <code>GOARCH=arm64</code>.
-</p>
-
-<h3 id="performance-compiler">Compiler toolchain</h3>
-
-<p><!-- CL 110055 -->
-  The compiler now optimizes map clearing operations of the form:
-</p>
-<pre>
-for k := range m {
-	delete(m, k)
-}
-</pre>
-
-<p><!-- CL 109517 -->
-  The compiler now optimizes slice extension of the form
-  <code>append(s,</code>&nbsp;<code>make([]T,</code>&nbsp;<code>n)...)</code>.
-</p>
-
-<p><!-- CL 100277, CL 105635, CL 109776 -->
-  The compiler now performs significantly more aggressive bounds-check
-  and branch elimination. Notably, it now recognizes transitive
-  relations, so if <code>i&lt;j</code> and <code>j&lt;len(s)</code>,
-  it can use these facts to eliminate the bounds check
-  for <code>s[i]</code>. It also understands simple arithmetic such
-  as <code>s[i-10]</code> and can recognize more inductive cases in
-  loops. Furthermore, the compiler now uses bounds information to more
-  aggressively optimize shift operations.
-</p>

-
-<p>
-  The latest Go release, version 1.12, arrives six months after <a href="go1.11">Go 1.11</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">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.

-  Go 1.12 is the last release that is supported on FreeBSD 10.x, which has
-  already reached end-of-life. Go 1.13 will require FreeBSD 11.2+ or FreeBSD
-  12.0+.
-  FreeBSD 12.0+ requires a kernel with the COMPAT_FREEBSD11 option set (this is the default).

-  <code>libSystem</code> is now used when making syscalls on Darwin,
-  ensuring forward-compatibility with future versions of macOS and iOS.
-  <!-- CL 153338 -->
-  The switch to <code>libSystem</code> triggered additional App Store
-  checks for private API usage. Since it is considered private,
-  <code>syscall.Getdirentries</code> now always fails with
-  <code>ENOSYS</code> on iOS.
-  Additionally, <a href="/pkg/syscall/#Setrlimit"><code>syscall.Setrlimit</code></a>
-  reports <code>invalid</code> <code>argument</code> in places where it historically
-  succeeded. These consequences are not specific to Go and users should expect
-  behavioral parity with <code>libSystem</code>'s implementation going forward.
-</p>
-
-<h2 id="tools">Tools</h2>
-
-<h3 id="vet"><code>go tool vet</code> no longer supported</h3>
-
-<p>
-  The <code>go vet</code> command has been rewritten to serve as the
-  base for a range of different source code analysis tools. See
-  the <a href="https://godoc.org/golang.org/x/tools/go/analysis">golang.org/x/tools/go/analysis</a>
-  package for details. A side-effect is that <code>go tool vet</code>
-  is no longer supported. External tools that use <code>go tool
-  vet</code> must be changed to use <code>go
-  vet</code>. Using <code>go vet</code> instead of <code>go tool
-  vet</code> should work with all supported versions of Go.
-</p>
-
-<p>
-  As part of this change, the experimental <code>-shadow</code> option
-  is no longer available with <code>go vet</code>. Checking for
-  variable shadowing may now be done using
-<pre>
-go get -u golang.org/x/tools/go/analysis/passes/shadow/cmd/shadow
-go vet -vettool=$(which shadow)
-</pre>

-<h3 id="tour">Tour</h3>
-
-<p> <!-- CL 152657 -->
-The Go tour is no longer included in the main binary distribution. To
-run the tour locally, instead of running <code>go</code> <code>tool</code> <code>tour</code>,
-manually install it:
-<pre>
-go get -u golang.org/x/tour

-</pre>
-</p>
-
-<h3 id="gocache">Build cache requirement</h3>
-
-<p>
-  The <a href="/cmd/go/#hdr-Build_and_test_caching">build cache</a> is now
-  required as a step toward eliminating
-  <code>$GOPATH/pkg</code>. Setting the environment variable
-  <code>GOCACHE=off</code> will cause <code>go</code> commands that write to the
-  cache to fail.
-</p>
-
-<h3 id="binary-only">Binary-only packages</h3>
-
-<p>
-  Go 1.12 is the last release that will support binary-only packages.
-</p>
-
-<h3 id="cgo">Cgo</h3>
-
-<p>
-	Go 1.12 will translate the C type <code>EGLDisplay</code> to the Go type <code>uintptr</code>.
-	This change is similar to how Go 1.10 and newer treats Darwin's CoreFoundation
-	and Java's JNI types. See the
-	<a href="/cmd/cgo/#hdr-Special_cases">cgo documentation</a>
-	for more information.
-</p>
-
-<p><!-- CL 152657 -->
-  Mangled C names are no longer accepted in packages that use Cgo. Use the Cgo
-  names instead. For example, use the documented cgo name <code>C.char</code>
-  rather than the mangled name <code>_Ctype_char</code> that cgo generates.
-</p>
-
-<h3 id="modules">Modules</h3>
-
-<p><!-- CL 148517 -->
-  When <code>GO111MODULE</code> is set to <code>on</code>, the <code>go</code>
-  command now supports module-aware operations outside of a module directory,
-  provided that those operations do not need to resolve import paths relative to
-  the current directory or explicitly edit the <code>go.mod</code> file.
-  Commands such as <code>go</code> <code>get</code>,
-  <code>go</code> <code>list</code>, and
-  <code>go</code> <code>mod</code> <code>download</code> behave as if in a
-  module with initially-empty requirements.
-  In this mode, <code>go</code> <code>env</code> <code>GOMOD</code> reports
-  the system's null device (<code>/dev/null</code> or <code>NUL</code>).
-</p>
-
-<p><!-- CL 146382 -->
-  <code>go</code> commands that download and extract modules are now safe to
-  invoke concurrently.
-  The module cache (<code>GOPATH/pkg/mod</code>) must reside in a filesystem that
-  supports file locking.
-</p>
-
-<p><!-- CL 147282, 147281 -->
-  The <code>go</code> directive in a <code>go.mod</code> file now indicates the
-  version of the language used by the files within that module.
-  It will be set to the current release
-  (<code>go</code> <code>1.12</code>) if no existing version is
-  present.
-  If the <code>go</code> directive for a module specifies a
-  version <em>newer</em> than the toolchain in use, the <code>go</code> command
-  will attempt to build the packages regardless, and will note the mismatch only if
-  that build fails.
-</p>
-
-<p><!-- CL 147282, 147281 -->
-  This changed use of the <code>go</code> directive means that if you
-  use Go 1.12 to build a module, thus recording <code>go 1.12</code>
-  in the <code>go.mod</code> file, you will get an error when
-  attempting to build the same module with Go 1.11 through Go 1.11.3.
-  Go 1.11.4 or later will work fine, as will releases older than Go 1.11.
-  If you must use Go 1.11 through 1.11.3, you can avoid the problem by
-  setting the language version to 1.11, using the Go 1.12 go tool,
-  via <code>go mod edit -go=1.11</code>.
-</p>
-
-<p><!-- CL 152739 -->
-  When an import cannot be resolved using the active modules,
-  the <code>go</code> command will now try to use the modules mentioned in the
-  main module's <code>replace</code> directives before consulting the module
-  cache and the usual network sources.
-  If a matching replacement is found but the <code>replace</code> directive does
-  not specify a version, the <code>go</code> command uses a pseudo-version
-  derived from the zero <code>time.Time</code> (such
-  as <code>v0.0.0-00010101000000-000000000000</code>).
-</p>
-
-<h3 id="compiler">Compiler toolchain</h3>
-
-<p><!-- CL 134155, 134156 -->
-  The compiler's live variable analysis has improved. This may mean that
-  finalizers will be executed sooner in this release than in previous
-  releases. If that is a problem, consider the appropriate addition of a
-  <a href="/pkg/runtime/#KeepAlive"><code>runtime.KeepAlive</code></a> call.
-</p>
-
-<p><!-- CL 147361 -->
-  More functions are now eligible for inlining by default, including
-  functions that do nothing but call another function.
-  This extra inlining makes it additionally important to use
-  <a href="/pkg/runtime/#CallersFrames"><code>runtime.CallersFrames</code></a>
-  instead of iterating over the result of
-  <a href="/pkg/runtime/#Callers"><code>runtime.Callers</code></a> directly.
-<pre>
-// Old code which no longer works correctly (it will miss inlined call frames).
-var pcs [10]uintptr
-n := runtime.Callers(1, pcs[:])
-for _, pc := range pcs[:n] {
-	f := runtime.FuncForPC(pc)
-	if f != nil {
-		fmt.Println(f.Name())
-	}
-}
-</pre>
-<pre>
-// New code which will work correctly.
-var pcs [10]uintptr
-n := runtime.Callers(1, pcs[:])
-frames := runtime.CallersFrames(pcs[:n])
-for {
-	frame, more := frames.Next()
-	fmt.Println(frame.Function)
-	if !more {
-		break
-	}
-}
-</pre>
-</p>
-
-<p><!-- CL 153477 -->
-  Wrappers generated by the compiler to implement method expressions
-  are no longer reported
-  by <a href="/pkg/runtime/#CallersFrames"><code>runtime.CallersFrames</code></a>
-  and <a href="/pkg/runtime/#Stack"><code>runtime.Stack</code></a>. They
-  are also not printed in panic stack traces.
-
-  This change aligns the <code>gc</code> toolchain to match
-  the <code>gccgo</code> toolchain, which already elided such wrappers
-  from stack traces.
-
-  Clients of these APIs might need to adjust for the missing
-  frames. For code that must interoperate between 1.11 and 1.12
-  releases, you can replace the method expression <code>x.M</code>
-  with the function literal <code>func (...) { x.M(...) } </code>.
-</p>
-
-<p><!-- CL 144340 -->
-  The compiler now accepts a <code>-lang</code> flag to set the Go language
-  version to use. For example, <code>-lang=go1.8</code> causes the compiler to
-  emit an error if the program uses type aliases, which were added in Go 1.9.
-  Language changes made before Go 1.12 are not consistently enforced.
-</p>
-
-<p><!-- CL 147160 -->
-  The compiler toolchain now uses different conventions to call Go
-  functions and assembly functions. This should be invisible to users,
-  except for calls that simultaneously cross between Go and
-  assembly <em>and</em> cross a package boundary. If linking results
-  in an error like "relocation target not defined for ABIInternal (but
-  is defined for ABI0)", please refer to the
-  <a href="https://github.com/golang/proposal/blob/master/design/27539-internal-abi.md#compatibility">compatibility section</a>
-  of the ABI design document.
-</p>
-
-<p><!-- CL 145179 -->
-  There have been many improvements to the DWARF debug information
-  produced by the compiler, including improvements to argument
-  printing and variable location information.
-</p>
-
-<p><!-- CL 61511 -->
-  Go programs now also maintain stack frame pointers on <code>linux/arm64</code>
-  for the benefit of profiling tools like <code>perf</code>. The frame pointer
-  maintenance has a small run-time overhead that varies but averages around 3%.
-  To build a toolchain that does not use frame pointers, set
-  <code>GOEXPERIMENT=noframepointer</code> when running <code>make.bash</code>.
-</p>
-
-<p><!-- CL 142717 -->
-  The obsolete "safe" compiler mode (enabled by the <code>-u</code> gcflag) has been removed.
-</p>
-
-<h3 id="godoc"><code>godoc</code> and <code>go</code> <code>doc</code></h3>
-
-<p>
-  In Go 1.12, <code>godoc</code> no longer has a command-line interface and
-  is only a web server. Users should use <code>go</code> <code>doc</code>
-  for command-line help output instead. Go 1.12 is the last release that will
-  include the <code>godoc</code> webserver; in Go 1.13 it will be available
-  via <code>go</code> <code>get</code>.
-</p>
-
-<p><!-- CL 141977 -->
-  <code>go</code> <code>doc</code> now supports the <code>-all</code> flag,
-  which will cause it to print all exported APIs and their documentation,
-  as the <code>godoc</code> command line used to do.
-</p>
-
-<p><!-- CL 140959 -->
-  <code>go</code> <code>doc</code> also now includes the <code>-src</code> flag,
-  which will show the target's source code.
-</p>
-
-<h3 id="trace">Trace</h3>
-
-<p><!-- CL 60790 -->
-  The trace tool now supports plotting mutator utilization curves,
-  including cross-references to the execution trace. These are useful
-  for analyzing the impact of the garbage collector on application
-  latency and throughput.
-</p>
-
-<h3 id="assembler">Assembler</h3>
-
-<p><!-- CL 147218 -->
-  On <code>arm64</code>, the platform register was renamed from

-<h3 id="tls_1_3">TLS 1.3</h3>
-
-<p>
-  Go 1.12 adds opt-in support for TLS 1.3 in the <code>crypto/tls</code> package as
-  specified by <a href="https://www.rfc-editor.org/info/rfc8446">RFC 8446</a>. It can
-  be enabled by adding the value <code>tls13=1</code> to the <code>GODEBUG</code>
-  environment variable. It will be enabled by default in Go 1.13.
-</p>
-
-<p>
-  To negotiate TLS 1.3, make sure you do not set an explicit <code>MaxVersion</code> in
-  <a href="/pkg/crypto/tls/#Config"><code>Config</code></a> and run your program with
-  the environment variable <code>GODEBUG=tls13=1</code> set.
-</p>
-
-<p>
-  All TLS 1.2 features except <code>TLSUnique</code> in
-  <a href="/pkg/crypto/tls/#ConnectionState"><code>ConnectionState</code></a>
-  and renegotiation are available in TLS 1.3 and provide equivalent or
-  better security and performance. Note that even though TLS 1.3 is backwards
-  compatible with previous versions, certain legacy systems might not work
-  correctly when attempting to negotiate it. RSA certificate keys too small
-  to be secure (including 512-bit keys) will not work with TLS 1.3.
-</p>
-
-<p>
-  TLS 1.3 cipher suites are not configurable. All supported cipher suites are
-  safe, and if <code>PreferServerCipherSuites</code> is set in
-  <a href="/pkg/crypto/tls/#Config"><code>Config</code></a> the preference order
-  is based on the available hardware.
-</p>
-
-<p>
-  Early data (also called "0-RTT mode") is not currently supported as a
-  client or server. Additionally, a Go 1.12 server does not support skipping
-  unexpected early data if a client sends it. Since TLS 1.3 0-RTT mode
-  involves clients keeping state regarding which servers support 0-RTT,
-  a Go 1.12 server cannot be part of a load-balancing pool where some other
-  servers do support 0-RTT. If switching a domain from a server that supported
-  0-RTT to a Go 1.12 server, 0-RTT would have to be disabled for at least the
-  lifetime of the issued session tickets before the switch to ensure
-  uninterrupted operation.
-</p>
-
-<p>
-  In TLS 1.3 the client is the last one to speak in the handshake, so if it causes
-  an error to occur on the server, it will be returned on the client by the first
-  <a href="/pkg/crypto/tls/#Conn.Read"><code>Read</code></a>, not by
-  <a href="/pkg/crypto/tls/#Conn.Handshake"><code>Handshake</code></a>. For
-  example, that will be the case if the server rejects the client certificate.
-  Similarly, session tickets are now post-handshake messages, so are only
-  received by the client upon its first
-  <a href="/pkg/crypto/tls/#Conn.Read"><code>Read</code></a>.
-</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.

-<h2 id="introduction">Introduction to Go 1.14</h2>
-
-<p>
-  The latest Go release, version 1.14, arrives six months after <a href="go1.13">Go 1.13</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>
-
-<p>
-  Module support in the <code>go</code> command is now ready for production use,
-  and we encourage all users to <a href="https://blog.golang.org/migrating-to-go-modules">migrate to Go
-  modules for dependency management</a>. If you are unable to migrate due to a problem in the Go
-  toolchain, please ensure that the problem has an
-  <a href="https://golang.org/issue?q=is%3Aissue+is%3Aopen+label%3Amodules">open issue</a>
-  filed. (If the issue is not on the <code>Go1.15</code> milestone, please let us
-  know why it prevents you from migrating so that we can prioritize it
-  appropriately.)
-</p>
-
-<h2 id="language">Changes to the language</h2>
-
-<p>
-  Per the <a href="https://github.com/golang/proposal/blob/master/design/6977-overlapping-interfaces.md">overlapping interfaces proposal</a>,
-  Go 1.14 now permits embedding of interfaces with overlapping method sets:
-  methods from an embedded interface may have the same names and identical signatures
-  as methods already present in the (embedding) interface. This solves problems that typically
-  (but not exclusively) occur with diamond-shaped embedding graphs.
-  Explicitly declared methods in an interface must remain
-  <a href="https://tip.golang.org/ref/spec#Uniqueness_of_identifiers">unique</a>, as before.
-</p>
-
-<h2 id="ports">Ports</h2>
-
-<h3 id="darwin">Darwin</h3>
-
-<p>
-  Go 1.14 is the last release that will run on macOS 10.11 El Capitan.
-  Go 1.15 will require macOS 10.12 Sierra or later.
-</p>
-
-<p><!-- golang.org/issue/34749 -->
-  Go 1.14 is the last Go release to support 32-bit binaries on
-  macOS (the <code>darwin/386</code> port). They are no longer
-  supported by macOS, starting with macOS 10.15 (Catalina).
-  Go continues to support the 64-bit <code>darwin/amd64</code> port.
-</p>
-
-<p><!-- golang.org/issue/34751 -->
-  Go 1.14 will likely be the last Go release to support 32-bit
-  binaries on iOS, iPadOS, watchOS, and tvOS
-  (the <code>darwin/arm</code> port). Go continues to support the
-  64-bit <code>darwin/arm64</code> port.

-</p>
-
-<p><!-- CL 202439 -->
-  On Windows, creating a file
-  via <a href="/pkg/os#CreateFile"><code>os.OpenFile</code></a> with
-  the <a href="/pkg/os/#O_CREATE"><code>os.O_CREATE</code></a> flag, or
-  via <a href="/pkg/syscall#Open"><code>syscall.Open</code></a> with
-  the <a href="/pkg/syscall#O_CREAT"><code>syscall.O_CREAT</code></a>
-  flag, will now create the file as read-only if the
-  bit <code>0o200</code> (owner write permission) is not set in the
-  permission argument. This makes the behavior on Windows more like
-  that on Unix systems.
-</p>

-
-<p><!-- CL 203600 -->
-  <code>js.Value</code> values can no longer be compared using
-  the <code>==</code> operator, and instead must be compared using
-  their <code>Equal</code> method.
-</p>
-
-<p><!-- CL 203600 -->
-  <code>js.Value</code> now

-<h4 id="vendor">Vendoring</h4>
-<!-- golang.org/issue/33848 -->
-
-<p>
-  When the main module contains a top-level <code>vendor</code> directory and
-  its <code>go.mod</code> file specifies <code>go</code> <code>1.14</code> or
-  higher, the <code>go</code> command now defaults to <code>-mod=vendor</code>
-  for operations that accept that flag. A new value for that flag,
-  <code>-mod=mod</code>, causes the <code>go</code> command to instead load
-  modules from the module cache (as when no <code>vendor</code> directory is
-  present).
-</p>
-
-<p>
-  When <code>-mod=vendor</code> is set (explicitly or by default), the
-  <code>go</code> command now verifies that the main module's
-  <code>vendor/modules.txt</code> file is consistent with its
-  <code>go.mod</code> file.
-</p>
-
-<p>
-  <code>go</code> <code>list</code> <code>-m</code> no longer silently omits
-  transitive dependencies that do not provide packages in
-  the <code>vendor</code> directory. It now fails explicitly if
-  <code>-mod=vendor</code> is set and information is requested for a module not
-  mentioned in <code>vendor/modules.txt</code>.
-</p>
-
-<h4 id="go-flags">Flags</h4>
-
-<p><!-- golang.org/issue/32502, golang.org/issue/30345 -->
-  The <code>go</code> <code>get</code> command no longer accepts
-  the <code>-mod</code> flag. Previously, the flag's setting either
-  <a href="https://golang.org/issue/30345">was ignored</a> or
-  <a href="https://golang.org/issue/32502">caused the build to fail</a>.
-</p>
-
-<p><!-- golang.org/issue/33326 -->
-  <code>-mod=readonly</code> is now set by default when the <code>go.mod</code>
-  file is read-only and no top-level <code>vendor</code> directory is present.
-</p>
-
-<p><!-- golang.org/issue/31481 -->
-  <code>-modcacherw</code> is a new flag that instructs the <code>go</code>
-  command to leave newly-created directories in the module cache at their
-  default permissions rather than making them read-only.
-  The use of this flag makes it more likely that tests or other tools will
-  accidentally add files not included in the module's verified checksum.
-  However, it allows the use of <code>rm</code> <code>-rf</code>
-  (instead of <code>go</code> <code>clean</code> <code>-modcache</code>)
-  to remove the module cache.
-</p>
-
-<p><!-- golang.org/issue/34506 -->
-  <code>-modfile=file</code> is a new flag that instructs the <code>go</code>
-  command to read (and possibly write) an alternate <code>go.mod</code> file
-  instead of the one in the module root directory. A file
-  named <code>go.mod</code> must still be present in order to determine the
-  module root directory, but it is not accessed. When <code>-modfile</code> is
-  specified, an alternate <code>go.sum</code> file is also used: its path is
-  derived from the <code>-modfile</code> flag by trimming the <code>.mod</code>
-  extension and appending <code>.sum</code>.
-</p>
-
-<h4 id="go-env-vars">Environment variables</h4>
-
-<p><!-- golang.org/issue/32966 -->
-  <code>GOINSECURE</code> is a new environment variable that instructs
-  the <code>go</code> command to not require an HTTPS connection, and to skip
-  certificate validation, when fetching certain modules directly from their
-  origins. Like the existing <code>GOPRIVATE</code> variable, the value
-  of <code>GOINSECURE</code> is a comma-separated list of glob patterns.
-</p>
-
-<h4 id="commands-outside-modules">Commands outside modules</h4>
-
-<p><!-- golang.org/issue/32027 -->
-  When module-aware mode is enabled explicitly (by setting
-  <code>GO111MODULE=on</code>), most module commands have more
-  limited functionality if no <code>go.mod</code> file is present. For
-  example, <code>go</code> <code>build</code>,
-  <code>go</code> <code>run</code>, and other build commands can only build
-  packages in the standard library and packages specified as <code>.go</code>
-  files on the command line.
-</p>
-
-<p>
-  Previously, the <code>go</code> command would resolve each package path
-  to the latest version of a module but would not record the module path
-  or version. This resulted in <a href="https://golang.org/issue/32027">slow,
-  non-reproducible builds</a>.
-</p>
-
-<p>
-  <code>go</code> <code>get</code> continues to work as before, as do
-  <code>go</code> <code>mod</code> <code>download</code> and
-  <code>go</code> <code>list</code> <code>-m</code> with explicit versions.
-</p>
-
-<h4 id="incompatible-versions"><code>+incompatible</code> versions</h4>
-<!-- golang.org/issue/34165 -->
-
-<p>
-  If the latest version of a module contains a <code>go.mod</code> file,
-  <code>go</code> <code>get</code> will no longer upgrade to an
-  <a href="/cmd/go/#hdr-Module_compatibility_and_semantic_versioning">incompatible</a>
-  major version of that module unless such a version is requested explicitly
-  or is already required.
-  <code>go</code> <code>list</code> also omits incompatible major versions
-  for such a module when fetching directly from version control, but may
-  include them if reported by a proxy.
-</p>
-
-
-<h4 id="go.mod"><code>go.mod</code> file maintenance</h4>
-<!-- golang.org/issue/34822 -->
-
-<p>
-  <code>go</code> commands other than
-  <code>go</code> <code>mod</code> <code>tidy</code> no longer
-  remove a <code>require</code> directive that specifies a version of an indirect dependency
-  that is already implied by other (transitive) dependencies of the main
-  module.
-</p>
-
-<p>
-  <code>go</code> commands other than
-  <code>go</code> <code>mod</code> <code>tidy</code> no longer
-  edit the <code>go.mod</code> file if the changes are only cosmetic.
-</p>
-
-<p>
-  When <code>-mod=readonly</code> is set, <code>go</code> commands will no
-  longer fail due to a missing <code>go</code> directive or an erroneous
-  <code>//&nbsp;indirect</code> comment.
-</p>
-
-<h4 id="module-downloading">Module downloading</h4>
-
-<p><!-- golang.org/issue/26092 -->
-  The <code>go</code> command now supports Subversion repositories in module mode.
-</p>
-
-<p><!-- golang.org/issue/30748 -->
-  The <code>go</code> command now includes snippets of plain-text error messages
-  from module proxies and other HTTP servers.
-  An error message will only be shown if it is valid UTF-8 and consists of only
-  graphic characters and spaces.
-</p>
-
-<h4 id="go-test">Testing</h4>
-
-<p><!-- golang.org/issue/24929 -->
-  <code>go test -v</code> now streams <code>t.Log</code> output as it happens,
-  rather than at the end of all tests.
-</p>
-
-<h2 id="runtime">Runtime</h2>
-
-<p><!-- CL 190098 -->
-  This release improves the performance of most uses
-  of <code>defer</code> to incur almost zero overhead compared to
-  calling the deferred function directly.
-  As a result, <code>defer</code> can now be used in
-  performance-critical code without overhead concerns.
-</p>
-
-<p><!-- CL 201760, CL 201762 and many others -->
-  Goroutines are now asynchronously preemptible.
-  As a result, loops without function calls no longer potentially
-  deadlock the scheduler or significantly delay garbage collection.
-  This is supported on all platforms except <code>windows/arm</code>,
-  <code>darwin/arm</code>, <code>js/wasm</code>, and
-  <code>plan9/*</code>.
-</p>
-
-<p>
-  A consequence of the implementation of preemption is that on Unix
-  systems, including Linux and macOS systems, programs built with Go
-  1.14 will receive more signals than programs built with earlier
-  releases.
-  This means that programs that use packages
-  like <a href="/pkg/syscall/"><code>syscall</code></a>
-  or <a href="https://godoc.org/golang.org/x/sys/unix"><code>golang.org/x/sys/unix</code></a>
-  will see more slow system calls fail with <code>EINTR</code> errors.
-  Those programs will have to handle those errors in some way, most
-  likely looping to try the system call again.  For more
-  information about this
-  see <a href="http://man7.org/linux/man-pages/man7/signal.7.html"><code>man
-  7 signal</code></a> for Linux systems or similar documentation for
-  other systems.
-</p>
-
-<p><!-- CL 201765, CL 195701 and many others -->
-  The page allocator is more efficient and incurs significantly less
-  lock contention at high values of <code>GOMAXPROCS</code>.
-  This is most noticeable as lower latency and higher throughput for
-  large allocations being done in parallel and at a high rate.
-</p>
-
-<p><!-- CL 171844 and many others -->
-  Internal timers, used by
-  <a href="/pkg/time/#After"><code>time.After</code></a>,
-  <a href="/pkg/time/#Tick"><code>time.Tick</code></a>,
-  <a href="/pkg/net/#Conn"><code>net.Conn.SetDeadline</code></a>,
-  and friends, are more efficient, with less lock contention and fewer
-  context switches.
-  This is a performance improvement that should not cause any user
-  visible changes.
-</p>
-
-<h2 id="compiler">Compiler</h2>
-
-<p><!-- CL 162237 -->
-  This release adds <code>-d=checkptr</code> as a compile-time option
-  for adding instrumentation to check that Go code is following
-  <code>unsafe.Pointer</code> safety rules dynamically.
-  This option is enabled by default (except on Windows) with
-  the <code>-race</code> or <code>-msan</code> flags, and can be
-  disabled with <code>-gcflags=all=-d=checkptr=0</code>.
-  Specifically, <code>-d=checkptr</code> checks the following:
-</p>
-
-<ol>
-  <li>
-    When converting <code>unsafe.Pointer</code> to <code>*T</code>,
-    the resulting pointer must be aligned appropriately
-    for <code>T</code>.
-  </li>
-  <li>
-    If the result of pointer arithmetic points into a Go heap object,
-    one of the <code>unsafe.Pointer</code>-typed operands must point
-    into the same object.
-  </li>
-</ol>
-
-<p>
-  Using <code>-d=checkptr</code> is not currently recommended on
-  Windows because it causes false alerts in the standard library.
-</p>
-
-<p><!-- CL 204338 -->
-  The compiler can now emit machine-readable logs of key optimizations
-  using the <code>-json</code> flag, including inlining, escape
-  analysis, bounds-check elimination, and nil-check elimination.
-</p>
-
-<p><!-- CL 196959 -->
-  Detailed escape analysis diagnostics (<code>-m=2</code>) now work again.
-  This had been dropped from the new escape analysis implementation in
-  the previous release.
-</p>
-
-<p><!-- CL 196217 -->
-  All Go symbols in macOS binaries now begin with an underscore,
-  following platform conventions.
-</p>
-
-<p><!-- CL 202117 -->
-  This release includes experimental support for compiler-inserted
-  coverage instrumentation for fuzzing.
-  See <a href="https://golang.org/issue/14565">issue 14565</a> for more
-  details.
-  This API may change in future releases.

-
-<h3 id="hash/maphash">New byte sequence hashing package</h3>
-
-<p> <!-- golang.org/issue/28322, CL 186877 -->
-  Go 1.14 includes a new package,
-  <a href="/pkg/hash/maphash/"><code>hash/maphash</code></a>,
-  which provides hash functions on byte sequences.
-  These hash functions are intended to be used to implement hash tables or
-  other data structures that need to map arbitrary strings or byte
-  sequences to a uniform distribution on unsigned 64-bit integers.
-</p>
-<p>
-  The hash functions are collision-resistant but not cryptographically secure.
-</p>
-<p>
-  The hash value of a given byte sequence is consistent within a
-  single process, but will be different in different processes.
-</p>
-
-<h3 id="minor_library_changes">Minor changes to the library</h3>

+<h2>Implementation</h2>
+
+<h3>Reporting a Security Bug</h3>
+
+<p>
+Please report to us any issues you find.
+This document explains how to do that and what to expect in return.
+</p>
+
+<p>
+All security bugs in the Go distribution should be reported by email to
+<a href="mailto:security@golang.org">security@golang.org</a>.
+This mail is delivered to a small security team.
+Your email will be acknowledged within 24 hours, and you'll receive a more
+detailed response to your email within 72 hours indicating the next steps in
+handling your report.
+If you would like, you can encrypt your report using our PGP key (listed below).
+</p>
+
+<p>
+Please use a descriptive subject line for your report email.
+After the initial reply to your report, the security team will endeavor to keep
+you informed of the progress being made towards a fix and full announcement.
+These updates will be sent at least every five days.
+In reality, this is more likely to be every 24-48 hours.
+</p>
+
+<p>
+If you have not received a reply to your email within 48 hours or you have not
+heard from the security team for the past five days please contact the Go
+security team directly:
+</p>
+
+<ul>
+<li>Primary security coordinator: <a href="mailto:adg@golang.org">Andrew Gerrand</a>  (<a href="https://drive.google.com/a/google.com/file/d/0B42ZAZN5yFufRldybEVNandRN2c/view">public key</a>).</li>
+<li>Secondary coordinator: <a href="mailto:agl@golang.org">Adam Langley</a> (<a href="https://www.imperialviolet.org/key.asc">public key</a>).</li>
+<li>If you receive no response, mail <a href="mailto:golang-dev@googlegroups.com">golang-dev@googlegroups.com</a> or use the <a href="https://groups.google.com/forum/#!forum/golang-dev">golang-dev web interface</a>.</li>
+</ul>
+
+<p>
+Please note that golang-dev is a public discussion forum.
+When escalating on this list, please do not disclose the details of the issue.
+Simply state that you're trying to reach a member of the security team.
+</p>
+
+<h3>Flagging Existing Issues as Security-related</h3>
+
+<p>
+If you believe that an <a href="https://golang.org/issue">existing issue</a>
+is security-related, we ask that you send an email to
+<a href="mailto:security@golang.org">security@golang.org</a>.
+The email should include the issue ID and a short description of why it should
+be handled according to this security policy.
+</p>
+
+<h3>Disclosure Process</h3>
+
+<p>The Go project uses the following disclosure process:</p>
+
+<ol>
+<li>Once the security report is received it is assigned a primary handler.
+This person coordinates the fix and release process.</li>
+<li>The issue is confirmed and a list of affected software is determined.</li>
+<li>Code is audited to find any potential similar problems.</li>
+<li>If it is determined, in consultation with the submitter, that a CVE-ID is
+required, the primary handler obtains one via email to
+<a href="http://oss-security.openwall.org/wiki/mailing-lists/distros">oss-distros</a>.</li>
+<li>Fixes are prepared for the two most recent major releases and the head/master
+revision. These fixes are not yet committed to the public repository.</li>
+<li>A notification is sent to the
+<a href="https://groups.google.com/group/golang-announce">golang-announce</a>
+mailing list to give users time to prepare their systems for the update.</li>
+<li>Three working days following this notification, the fixes are applied to
+the <a href="https://go.googlesource.com/go">public repository</a> and a new
+Go release is issued.</li>
+<li>On the date that the fixes are applied, announcements are sent to
+<a href="https://groups.google.com/group/golang-announce">golang-announce</a>,
+<a href="https://groups.google.com/group/golang-dev">golang-dev</a>, and
+<a href="https://groups.google.com/group/golang-nuts">golang-nuts</a>.
+</ol>
+
+<p>
+This process can take some time, especially when coordination is required with
+maintainers of other projects. Every effort will be made to handle the bug in
+as timely a manner as possible, however it's important that we follow the
+process described above to ensure that disclosures are handled consistently.
+</p>
+
+<p>
+For security issues that include the assignment of a CVE-ID,
+the issue is listed publicly under the
+<a href="https://www.cvedetails.com/vulnerability-list/vendor_id-14185/Golang.html">"Golang" product on the CVEDetails website</a>
+as well as the
+<a href="https://web.nvd.nist.gov/view/vuln/search">National Vulnerability Disclosure site</a>.
+</p>
+
+<h3>Receiving Security Updates</h3>
+
+<p>
+The best way to receive security announcements is to subscribe to the
+<a href="https://groups.google.com/forum/#!forum/golang-announce">golang-announce</a>
+mailing list. Any messages pertaining to a security issue will be prefixed
+with <code>[security]</code>.
+</p>
+
+<h3>Comments on This Policy</h3>
+
+<p>
+If you have any suggestions to improve this policy, please send an email to
+<a href="mailto:golang-dev@golang.org">golang-dev@golang.org</a> for discussion.
+</p>
