-	"Title": "Pre-Go 1 Release History"
-}-->
-
-<p>
-This page summarizes the changes between stable releases of Go prior to Go 1.
-See the <a href="release.html">Release History</a> page for notes on recent releases.
-</p>
-
-<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>
-
-<h3 id="r60.minor">Minor revisions</h3>
-
-<p>
-r60.1 includes a 
-<a href="//golang.org/change/1824581bf62d">linker
-fix</a>, a pair of
-<a href="//golang.org/change/9ef4429c2c64">goplay</a>
-<a href="//golang.org/change/d42ed8c3098e">fixes</a>,
-and a <code>json</code> package
-<a href="//golang.org/change/d5e97874fe84">fix</a> and
-a new
-<a href="//golang.org/change/4f0e6269213f">struct tag
-option</a>.
-</p>
-
-<p>
-r60.2
-<a href="//golang.org/change/ff19536042ac">fixes</a>
-a memory leak involving maps.
-</p>
-
-<p>
-r60.3 fixes a
-<a href="//golang.org/change/01fa62f5e4e5">reflect bug</a>.
-</p>
-
-<h2 id="r59">r59 (released 2011/08/01)</h2>
-
-<p>
-The r59 release corresponds to 
-<code><a href="weekly.html#2011-07-07">weekly.2011-07-07</a></code>.
-This section highlights the most significant changes in this release.
-For a more detailed summary, see the
-<a href="weekly.html#2011-07-07">weekly release notes</a>.
-For complete information, see the
-<a href="//code.google.com/p/go/source/list?r=release-branch.r59">Mercurial change list</a>.
-</p>
-
-<h3 id="r59.lang">Language</h3>
-
-<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>
-	type T struct {
-		X int `json:"name"`  // or `xml:"name"`
-	}
-</pre>
-<p>
-Use <a href="/cmd/govet/">govet</a> to identify struct tags that need to be
-changed to use the new syntax.
-</p>
-
-<p>
-<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
-arbitrary remote repositories (not just Google Code, Github, and so on).
-See the <a href="/cmd/goinstall/">goinstall documentation</a> for details.
-</p>
-
-<h2 id="r58">r58 (released 2011/06/29)</h2>
-
-<p>
-The r58 release corresponds to 
-<code><a href="weekly.html#2011-06-09">weekly.2011-06-09</a></code>
-with additional bug fixes.
-This section highlights the most significant changes in this release.
-For a more detailed summary, see the
-<a href="weekly.html#2011-06-09">weekly release notes</a>.
-For complete information, see the
-<a href="//code.google.com/p/go/source/list?r=release-branch.r58">Mercurial change list</a>.
-</p>
-
-<h3 id="r58.lang">Language</h3>
-
-<p>
-This release fixes a <a href="//golang.org/change/b720749486e1">use of uninitialized memory in programs that misuse <code>goto</code></a>.
-</p>
-
-<h3 id="r58.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> drops the <code>finalURL</code> return
-value from the <a href="/pkg/http/#Client.Get">Client.Get</a> method. The value
-is now available via the new <code>Request</code> field on <a
-href="/pkg/http/#Response">http.Response</a>.
-Most instances of the type map[string][]string in have been
-replaced with the new <a href="/pkg/http/#Values">Values</a> type.
-</p>
-
-<p>
-<a href="/pkg/exec/">Package exec</a> has been redesigned with a more
-convenient and succinct API.
-</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>
-formatting directive. The previous quoting behavior is still available via
-strconv's new <a href="/pkg/strconv/#QuoteToASCII">QuoteToASCII</a> function.   
-</p>
-
-<p>
-<a href="/pkg/os/signal/">Package os/signal</a>'s
-<a href="/pkg/os/#Signal">Signal</a> and 
-<a href="/pkg/os/#UnixSignal">UnixSignal</a> types have been moved to the
-<a href="/pkg/os/">os</a> package.
-</p>
-
-<p>
-<a href="/pkg/image/draw/">Package image/draw</a> is the new name for
-<code>exp/draw</code>. The GUI-related code from <code>exp/draw</code> is now
-located in the <a href="/pkg/exp/gui/">exp/gui</a> package.
-</p>
-
-<h3 id="r58.cmd">Tools</h3>
-
-<p>
-<a href="/cmd/goinstall/">Goinstall</a> now observes the GOPATH environment
-variable to build and install your own code and external libraries outside of
-the Go tree (and avoid writing Makefiles).
-</p>
-
-
-<h3 id="r58.minor">Minor revisions</h3>
-
-<p>r58.1 adds 
-<a href="//golang.org/change/293c25943586">build</a> and
-<a href="//golang.org/change/bf17e96b6582">runtime</a>
-changes to make Go run on OS X 10.7 Lion.
-</p>
-
-<h2 id="r57">r57 (released 2011/05/03)</h2>
-
-<p>
-The r57 release corresponds to 
-<code><a href="weekly.html#2011-04-27">weekly.2011-04-27</a></code>
-with additional bug fixes.
-This section highlights the most significant changes in this release.
-For a more detailed summary, see the
-<a href="weekly.html#2011-04-27">weekly release notes</a>.
-For complete information, see the
-<a href="//code.google.com/p/go/source/list?r=release-branch.r57">Mercurial change list</a>.
-</p>
-
-<p>The new <a href="/cmd/gofix">gofix</a> tool finds Go programs that use old APIs and rewrites them to use
-newer ones.  After you update to a new Go release, gofix helps make the
-necessary changes to your programs. Gofix will handle the http, os, and syscall
-package changes described below, and we will update the program to keep up with
-future changes to the libraries. 
-Gofix can’t
-handle all situations perfectly, so read and test the changes it makes before
-committing them.
-See <a href="//blog.golang.org/2011/04/introducing-gofix.html">the gofix blog post</a> for more
-information.</p>
-
-<h3 id="r57.lang">Language</h3>
-
-<p>
-<a href="/doc/go_spec.html#Receive_operator">Multiple assignment syntax</a> replaces the <code>closed</code> function.
-The syntax for channel
-receives allows an optional second assigned value, a boolean value
-indicating whether the channel is closed. This code:
-</p>
-
-<pre>
-	v := &lt;-ch
-	if closed(ch) {
-		// channel is closed
-	}
-</pre>
-
-<p>should now be written as:</p>
-
-<pre>
-	v, ok := &lt;-ch
-	if !ok {
-		// channel is closed
-	}
-</pre>
-
-<p><a href="/doc/go_spec.html#Label_scopes">Unused labels are now illegal</a>, just as unused local variables are.</p>
-
-<h3 id="r57.pkg">Packages</h3>
-
-<p>
-<a href="/pkg/gob/">Package gob</a> will now encode and decode values of types that implement the
-<a href="/pkg/gob/#GobEncoder">GobEncoder</a> and
-<a href="/pkg/gob/#GobDecoder">GobDecoder</a> interfaces. This allows types with unexported
-fields to transmit self-consistent descriptions; examples include 
-<a href="/pkg/big/#Int.GobDecode">big.Int</a> and <a href="/pkg/big/#Rat.GobDecode">big.Rat</a>.
-</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>
-and <a href="/pkg/os/#File.Create">Create</a> functions.
-The original Open is now available as <a href="/pkg/os/#File.OpenFile">OpenFile</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>
-
-<p>
-Remember that gofix will handle the bulk of the rewrites
-necessary for these changes to package APIs.
-</p>
-
-<h3 id="r57.cmd">Tools</h3>
-
-<p><a href="/cmd/gofix/">Gofix</a>, a new command, is described above.</p>
-
-<p>
-<a href="/cmd/gotest/">Gotest</a> is now a Go program instead of a shell script.
-The new <code>-test.short</code> flag in combination with package testing's Short function
-allows you to write tests that can be run in normal or &ldquo;short&rdquo; mode;
-all.bash runs tests in short mode to reduce installation time.
-The Makefiles know about the flag: use <code>make testshort</code>.
-</p>
-
-<p>
-The run-time support now implements CPU and memory profiling.
-Gotest's new 
-<a href="/cmd/gotest/"><code>-test.cpuprofile</code> and
-<code>-test.memprofile</code> flags</a> make it easy to
-profile tests.
-To add profiling to your web server, see the <a href="/pkg/http/pprof/">http/pprof</a>
-documentation.
-For other uses, see the <a href="/pkg/runtime/pprof/">runtime/pprof</a> documentation.

-curious, this weekly snapshot is the one to try. We'll issue a new App Engine
-Go 1 beta SDK very soon, so if you're an App Engine user you can try it there
-too.
-
-To help us focus on any remaining bugs and avoid introducing new ones, we will
-restrict our attention to critical fixes and issues marked Go1-Must in the

-This snapshot includes a major re-design of the go/build package.
-Its FindTree, ScanDir, Tree, and DirInfo types have been replaced with the
-Import and Package types. There is no gofix. Code that uses go/build will need
-to be updated manually to use the package's new interface.

-This weekly snapshot includes changes to the os and runtime packages.
-
-This should be the last of the significant incompatible changes before Go 1.
-
-There are no longer error constants such as EINVAL in the os package, since the
-set of values varied with the underlying operating system. There are new
-portable functions like IsPermission to test common error properties, plus a
-few new error values with more Go-like names, such as ErrPermission and
-ErrNoEnv.
-
-The os.Getenverror function has been removed. To distinguish between a
-non-existent environment variable and an empty string, use os.Environ or
-syscall.Getenv.
-
-The Process.Wait method has dropped its option argument and the associated
-constants are gone from the package. Also, the function Wait is gone; only the
-method of the Process type persists.
-
-The non-portable Waitmsg type has been replaced with the portable ProcessState.
-
-Much of the API exported by package runtime has been removed in favor of
-functionality provided by other packages. Code using the runtime.Type
-interface or its specific concrete type implementations should now use package
-reflect.  Code using runtime.Semacquire or runtime.Semrelease should use
-channels or the abstractions in package sync.
-
-The runtime.Alloc, runtime.Free, and runtime.Lookup functions, an unsafe API
-created for debugging the memory allocator, have no replacement.
-
-The runtime.Cgocalls and runtime.Goroutines functions have been renamed to
-runtime.NumCgoCall and runtime.NumGoroutine.
-
-The "go fix" command will update code to accommodate most of these changes.

-This weekly snapshot includes a re-organization of the Go tools.
-
-Only the go, godoc, and gofmt tools are installed to $GOROOT/bin (or $GOBIN).
-The remainder are installed to $GOROOT/bin/tool.
-This puts the lesser-used tools (6g, cgo, govet, etc.) outside the user PATH.
-Instead these tools may be called through the go tool with 'go tool command'.
-For example, to vet hello.go you would type 'go tool vet hello.go'.
-Type 'go tool' see the list of available tools.
-
-With the move, some tools were given simpler names:
-	6cov    -&gt; cov
-	6nm     -&gt; nm
-	goapi   -&gt; api

-
-<pre>
-This snapshot includes a language change and changes to the strconv and go/doc
-packages. The package changes require changes to client code.
-The language change is backwards-compatible.
-
-Type elision in arrays, slices, or maps of composite literals has been
-extended to include pointers to composite literals. Code like this
-	var t = []*T{&amp;T{}, &amp;T{}}
-may now be written as
-	var t = []*T{{}, {}}
-You can use gofmt -s to simplify such code.
-
-The strconv package has been given a more idiomatic and efficient interface.
-Client code can be updated with gofix. See the docs for the details:
-	http://weekly.golang.org/pkg/strconv/
-
-The go/doc package's ToHTML function now takes a []byte argument instead of a
-string.
-
-Other changes:
-* crypto/aes: eliminate some bounds checking and truncation (thanks Rémy Oudompheng).
-* crypto/x509: if a parent cert has a raw subject, use it.
-* encoding/gob: don't send type info for unexported fields.
-* exp/ssh: allow for msgUserAuthBanner during authentication (thanks Gustav Paul).
-* fmt: benchmark floating point,
-	only use Stringer or Error for strings.
-* gc: changes in export format in preparation of inlining,
-	disallow map/func equality via interface comparison,
-	use gofmt spacing when printing map type.
-* go/doc: exclude lines ending in ':' from possible headings.
-* gobuilder: -commit mode for packages,
-	cripple -package mode temporarily,
-	use new dashboard protocol.
-* godoc: improved output of examples in html (thanks Volker Dobler).
-* gofmt: handle &T in composite literal simplify.
-* goinstall: honour -install=false flag when -make=true.
-* hash: rewrite comment on Hash.Sum method.
-* html: more parser improvements (thanks Andrew Balholm).
-* image: avoid func comparison during ColorModel comparison.
-* math: add special-cases comments to Sinh and Tanh (thanks Charles L. Dorian).
-* misc/dashboard: further implementation work.
-* net, syscall: remove BindToDevice from UDPConn, IPConn (thanks Mikio Hara).
-* net/mail: correctly compare parsed times in the test.
-* os/exec: make LookPath always search CWD under Windows (thanks Benny Siegert).
-* runtime: prep for type-specific algorithms.
-* strconv: 34% to 63% faster conversions.

-This weekly snapshot includes changes to the hash package and a gofix for the
-time and os.FileInfo changes in the last snapshot.
-
-The hash.Hash's Sum method has been given a []byte argument,
-permitting the user to append the hash to an existing byte slice.
-Existing code that uses Sum can pass nil as the argument.
-Gofix will make this change automatically.
-
-Other changes:
-* crypto/tls: cleanup certificate load on windows (thanks Alex Brainman).
-* exp/ssh: add Std{in,out,err}Pipe methods to Session (thanks Dave Cheney).
-* dashboard: don't choke on weird builder names.
-* exp/ssh: export type signal, now Signal (thanks Gustav Paul).
-* os: add ModeType constant to mask file type bits (thanks Gustavo Niemeyer).
-* text/template: replace Add with AddParseTree.
-* go/doc: detect headings and format them in html (thanks Volker Dobler).

-
-<h2 id="2011-12-01">2011-12-01</h2>
-
-<pre>
-This weekly snapshot includes changes to the time, os, and text/template
-packages. The changes to the time and os packages are significant and related.
-Code that uses package time, package text/template, or package os's FileInfo
-type will require changes.
-
-In package time, there is now one type - time.Time - to represent times.
-Note that time.Time should be used as a value, in contrast to old code
-which typically used a *time.Time, a pointer to a large struct.  (Drop the *.)
-Any function that previously accepted a *time.Time, an int64
-number of seconds since 1970, or an int64 number of nanoseconds
-since 1970 should now accept a time.Time.  Especially as a replacement
-for the int64s, the type is good documentation about the meaning of
-its value.
-
-Whether you were previously calling time.Seconds, time.Nanoseconds,
-time.LocalTime, or time.UTC, the replacement is the new function
-time.Now.
-
-If you previously wrote code like:
-
-       t0 := time.Nanoseconds()
-       myFunction()
-       t1 := time.Nanoseconds()
-       delta := t1 - t0
-       fmt.Printf("That took %.2f seconds\n", float64(t1-t0)/1e9)
-
-you can now write:
-
-       t0 := time.Now()
-       myFunction()
-       t1 := time.Now()
-       delta := t1.Sub(t0)
-       fmt.Printf("That took %s\n", delta)
-
-In this snippet, the variable delta is of the new type time.Duration, the
-replacement for the many int64 parameters that were nanosecond
-counts (but not since 1970).
-
-Gofix can do the above conversions and some others, but it does not
-rewrite explicit int64 types as time.Time. It is very likely that you will
-need to edit your program to change these types after running gofix.
-As always, be sure to read the changes that gofix makes using your
-version control system's diff feature.
-
-See http://weekly.golang.org/pkg/time/ for details.
-
-In package os, the FileInfo struct is replaced by a FileInfo interface,
-admitting implementations by code beyond the operating system.
-Code that refers to *os.FileInfo (a pointer to the old struct) should
-instead refer to os.FileInfo (the new interface).
-The interface has just a few methods:
-
-       type FileInfo interface {
-               Name() string       // base name of the file
-               Size() int64        // length in bytes
-               Mode() FileMode     // file mode bits
-               ModTime() time.Time // modification time
-               IsDir() bool        // abbreviation for Mode().IsDir()
-       }
-
-If you need access to the underlying stat_t provided by the operating
-system kernel, you can access it by assuming that the FileInfo you are
-holding is actually an *os.FileStat, and that it's Sys field is actually a
-*syscall.Stat_t, as in:
-
-       dev := fi.(*os.FileStat).Sys.(*syscall.Stat_t).Dev
-
-Of course, this is not necessarily portable across different operating
-systems.
-
-Gofix will take care of rewriting *os.FileInfo to os.FileInfo for you,
-and it will also rewrite expressions like fi.Name into calls like fi.Name().
-
-See http://weekly.golang.org/pkg/os/#FileInfo for details.
-
-The template package has been changed to export a new, simpler API.
-The Set type is gone. Instead, templates are automatically associated by
-being parsed together; nested definitions implicitly create associations.
-Only associated templates can invoke one another.
-This approach dramatically reduces the breadth of the construction API.
-The html/template package has been updated also.
-There's a gofix for the simplest and most common uses of the old API.
-Code that doesn't mention the Set type is likely to work after running gofix;
-code that uses Set will need to be updated by hand.
-The template definition language itself is unchanged.
-
-See http://weekly.golang.org/pkg/text/template/ for details.
-
-
-Other changes:
-* cgo: add support for callbacks from dynamic libraries.
-* codereview: gofmt check for non-src/ files (thanks David Crawshaw).

-This snapshot includes some language changes.
-
-Map and function value comparisons are now disallowed (except for comparison
-with nil) as per the Go 1 plan. Function equality was problematic in some
-contexts and map equality compares pointers, not the maps' content.
-
-As an experiment, structs are now allowed to be copied even if they contain
-unexported fields. This gives packages the ability to return opaque values in
-their APIs.

-This weekly snapshot includes some package changes.
-
-In preparation for the Go 1 package reorganziation the sources for various
-packages have been moved, but the import paths remain unchanged. This
-inconsistency breaks goinstall at this snapshot. If you use goinstall, please
-stay synced to the previous weekly snapshot until the next one is tagged.
-
-The Error methods in the html, bzip2, and sql packages that return error values
-have been renamed to Err.
-
-Some non-core parts of the http package have been moved to net/http/httputil.
-The Dump* and NewChunked* functions and ClientConn, ServerConn, and
-ReverseProxy types have been moved from http to httputil.
-
-The API for html/template is now a direct copy of the template API, instead of
-exposing a single Escape function. For HTML templates, use the
-html/template package as you would the template package.
-
-Other changes:
-* all: rename os.EOF to io.EOF in non-code contexts (thanks Vincent Vanackere),
-	sort imports with gofix.
-* archive/zip: close file opened with OpenReader (thanks Dmitry Chestnykh).

-<h2 id="2011-11-02">2011-11-02 (new error type)</h2>
-
-<pre>
-This snapshot introduces the built-in error type, defined as
-
-       type error interface {
-               Error() string
-       }
-
-The error type replaces os.Error. Notice that the method name has changed from
-String to Error. Package fmt's Print formats both Stringers and errors:
-in general there is no need to implement both String and Error methods.
-
-Gofix can update most code. If you have split your package across many files,
-it may help to use the -force=error command-line option, which forces gofix to
-apply the error fix even if it is not obvious that a particular file needs it.
-As always, it is a good idea to read and test the changes that gofix made
-before committing them to your version control system.

-<h2 id="2011-10-26">2011-10-26 (new rune type)</h2>
-
-<pre>
-This snapshot introduces the rune type, an alias for int that
-should be used for Unicode code points.
-
-A future release of Go (after Go 1) will change rune to be an
-alias for int32 instead of int.  Using rune consistently is the way
-to make your code build both before and after this change.
-
-To test your code for rune safety, you can rebuild the Go tree with
-
-	GOEXPERIMENT=rune32 ./all.bash
-
-which builds a compiler in which rune is an alias for int32 instead of int.
-
-Also, run govet on your code to identify methods that might need to have their
-signatures updated.

-
-<pre>
-This weekly snapshot includes some language and package changes that may
-require code changes. Please read these notes carefully, as there are many
-changes and your code will likely be affected.
-
-The syntax for map deletion has been changed. Code that looks like:
-	m[x] = 0, false
-should be written as:
-	delete(m, x)
-The compiler still accepts m[x] = 0, false for now; even so, you can use gofix
-to rewrite such assignments into delete(m, x).
-
-The Go compiler will reject a return statement without arguments when any of
-the result variables has been shadowed. Code rejected as a result of this
-change is likely to be buggy.
-
-Receive-only channels (&lt;-chan T) cannot be closed.
-The compiler will diagnose such attempts.
-
-The first element of a map iteration is chosen at random. Code that depends on
-iteration order will need to be updated.
-
-Goroutines may be run during program initialization.
-
-A string may be appended to a byte slice. This code is now legal:
-	var b []byte
-	var s string
-	b = append(b, s...)
-
-The gotry command and its associated try package have been deleted.
-It was a fun experiment that - in the end - didn't carry its weight.
-
-The gotype tool has been moved to exp/gotype and its associated go/types
-package has been moved to exp/types. The deprecated go/typechecker package has
-been deleted.
-
-The enbflint tool has been moved to pkg/exp/ebnflint and its associated ebnf
-package has been moved to pkg/exp/ebnf.

-<h2 id="2011-10-06">2011-10-06</h2>
-
-<pre>
-This weekly snapshot includes changes to the io, image, and math packages that
-may require changes to client code.
-
-The io package's Copyn function has been renamed to CopyN.
-
-The math package's Fabs, Fdim, Fmax, Fmin and Fmod functions
-have been renamed to Abs, Dim, Max, Min, and Mod.
-
-Parts of the image package have been moved to the new image/color package.
-The spin-off renames some types. The new names are simply better:
-	image.Color              -&gt; color.Color
-	image.ColorModel         -&gt; color.Model
-	image.ColorModelFunc     -&gt; color.ModelFunc
-	image.PalettedColorModel -&gt; color.Palette
-	image.RGBAColor          -&gt; color.RGBA
-	image.RGBAColorModel     -&gt; color.RGBAModel
-	image.RGBA64Color        -&gt; color.RGBA64
-	image.RGBA64ColorModel   -&gt; color.RGBA64Model
-(similarly for NRGBAColor, GrayColorModel, etc)
-The image.ColorImage type stays in the image package, but is renamed:
-	image.ColorImage -&gt; image.Uniform
-The image.Image implementations (image.RGBA, image.RGBA64, image.NRGBA,
-image.Alpha, etc) do not change their name, and gain a nice symmetry:
-an image.RGBA is an image of color.RGBA, etc.
-The image.Black, image.Opaque uniform images remain unchanged (although their
-type is renamed from image.ColorImage to image.Uniform).
-The corresponding color types (color.Black, color.Opaque, etc) are new.
-Nothing in the image/ycbcr is renamed yet. The ycbcr.YCbCrColor and
-ycbcr.YCbCrImage types will eventually migrate to color.YCbCr and image.YCbCr,
-at a later date.

-<h2 id="2011-09-16">2011-09-16</h2>
-
-<pre>
-This weekly snapshot includes changes to the image, path/filepath, and time
-packages. Code that uses these packages may need to be updated.
-
-The image package's NewX functions (NewRGBA, NewNRGBA, etc) have been changed
-to take a Rectangle argument instead of a width and height.
-Gofix can make these changes automatically.
-
-The path/filepath package's Walk function has been changed to take a WalkFunc
-function value instead of a Visitor interface value. WalkFunc is like the
-Visitor's VisitDir and VisitFile methods except it handles both files and
-directories:
-	func(path string, info *os.FileInfo, err os.Error) os.Error
-To skip walking a directory (like returning false from VisitDir) the WalkFunc
-must return SkipDir.
-
-The time package's Time struct's Weekday field has been changed to a method.
-The value is calculated on demand, avoiding the need to re-parse
-programmatically-constructed Time values to find the correct weekday.
-
-There are no gofixes for the filepath or time API changes, but instances of the
-old APIs will be caught by the compiler. The Weekday one is easy to update by
-hand. The Walk one may take more consideration, but will have fewer instances
-to fix.

-<h2 id="2011-07-19">2011-07-19</h2>
-
-<pre>
-This weekly snapshot includes a language change and a change to the image
-package that may require changes to client code.
-
-The language change is that 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, programs will not be affected unless they contain "else for",
-"else switch", or "else select". Run gofmt to fix any such programs.
-
-The image package has had significant changes made to the Pix field of struct
-types such as image.RGBA and image.NRGBA. The image.Image interface type has
-not changed, though, and you should not need to change your code if you don't
-explicitly refer to Pix fields. For example, if you decode a number of images
-using the image/jpeg package, compose them using image/draw, and then encode
-the result using image/png, then your code should still work as before.
-
-If you do explicitly refer to Pix fields, there are two changes.  First, Pix[0]
-now refers to the pixel at Bounds().Min instead of the pixel at (0, 0). Second,
-the element type of the Pix slice is now uint8 instead of image.FooColor. For
-example, for an image.RGBA, the channel values will be packed R, G, B, A, R, G,
-B, A, etc. For 16-bits-per-channel color types, the pixel data will be stored
-as big-endian uint8s.
-
-Most Pix field types have changed, and so if your code still compiles after
-this change, then you probably don't need to make any further changes (unless
-you use an image.Paletted's Pix field). If you do get compiler errors, code
-that used to look like this:
-
-	// Get the R, G, B, A values for the pixel at (x, y).
-	var m *image.RGBA = loadAnImage()
-	c := m.Pix[y*m.Stride + x]
-	r, g, b, a := c.R, c.G, c.B, c.A
-
-should now look like this:
-
-	// Get the R, G, B, A values for the pixel at (x, y).
-	var m *image.RGBA = loadAnImage()
-	i := (y-m.Rect.Min.Y)*m.Stride + (x-m.Rect.Min.X)*4
-	r := m.Pix[i+0]
-	g := m.Pix[i+1]
-	b := m.Pix[i+2]
-	a := m.Pix[i+3]
-
-This image package change will not be fixed by gofix: how best to translate
-code into something efficient and idiomatic depends on the surrounding context,
-and is not easily automatable. Examples of what to do can be found in the
-changes to image/draw/draw.go in http://codereview.appspot.com/4675076/

-
-<pre>
-This weekly snapshot includes changes to the strings, http, reflect, json, and
-xml packages. Code that uses these packages will need changes. Most of these
-changes can be made automatically with gofix.
-
-The strings package's Split function has itself been split into Split and
-SplitN. SplitN is the same as the old Split. The new Split is equivalent to
-SplitN with a final argument of -1.
-
-The http package has a new FileSystem interface that provides access to files.
-The FileServer helper now takes a FileSystem argument instead of an explicit
-file system root. By implementing your own FileSystem you can use the
-FileServer to serve arbitrary data.
-
-The reflect package 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:
-        key:"value" key2:"value2"
-reflect.StructField's Tag field now has type StructTag (a string type), which
-has method Get(key string) string that returns the associated value.
-Clients of json and xml will need to be updated. Code that says
-        type T struct {
-                X int "name"
-        }
-should become
-        type T struct {
-                X int `json:"name"`  // or `xml:"name"`
-        }
-Use govet to identify struct tags that need to be changed to use the new syntax.

-This snapshot includes changes to the strconv, http, and exp/draw packages.
-Client code that uses the http or exp/draw packages will need to be changed,
-and code that uses strconv or fmt's "%q" formatting directive merits checking.
-
-The strconv package's Quote function now escapes only those Unicode code points
-not classified as printable by unicode.IsPrint. Previously Quote would escape
-all non-ASCII characters. This also affects the fmt package's "%q" formatting
-directive. The previous quoting behavior is still available via strconv's new
-QuoteToASCII function.   
-
-Most instances of the type map[string][]string in the http package have been
-replaced with the new Values type. The http.Values type has the Get, Set, Add,
-and Del helper methods to make working with query parameters and form values
-more convenient.
-
-The exp/draw package has been split into the image/draw and exp/gui packages.

-This snapshot includes changes to the exec package that will require changes
-to client code.
-
-The exec package has been re-designed with a more convenient and succinct API.
-This code:
-	args := []string{"diff", "-u", "file1.txt", "file2.txt"}
-	p, err := exec.Run("/usr/bin/diff", args, os.Environ(), "",
-		exec.DevNull, exec.Pipe, exec.DevNull)
-	if err != nil {
-		return nil, err
-	}
-	var buf bytes.Buffer

-	w, err := p.Wait(0)
-	p.Close()
-	if err != nil {
-		return nil, err
-	}

-This snapshot includes changes to the http package that will require changes to
-client code.
-
-The finalURL return value of the Client.Get method has been removed.
-This value is now accessible via the new Request field on http.Response.
-For example, this code:

-
-should be rewritten as:
-
-	res, err := http.Get(...)

-weekly.2011-04-13
-
-This weekly snapshot includes major changes to the reflect package and the
-os.Open function.  Code that uses reflect or os.Open will require updating,
-which can be done mechanically using the gofix tool.
-
-The reflect package's Type and Value types have changed.  Type is now an
-interface that implements all the possible type methods.  Instead of a type
-switch on a reflect.Type t, switch on t.Kind().  Value is now a struct value
-that implements all the possible value methods.  Instead of a type switch on a
-reflect.Value v, switch on v.Kind().  See the change for the full details:
-        http://code.google.com/p/go/source/detail?r=843855f3c026
-
-The os package's Open function has been replaced by three functions:
-        OpenFile(name, flag, perm) // same as old Open
-        Open(name) // same as old Open(name, O_RDONLY, 0)
-        Create(name) // same as old Open(name, O_RDWR|O_TRUNC|O_CREAT, 0666)
-
-To update your code to use the new APIs, run "gofix path/to/code".  Gofix can't
-handle all situations perfectly, so read and test the changes it makes before
-committing them.

-This weekly release includes improved support for testing.
-
-Memory and CPU profiling is now available via the gotest tool. Gotest will

-
-We have also introduced a way for tests to run quickly when an exhaustive test
-is unnecessary. Gotest's new -test.short flag in combination with the testing
-package's new Short function allows you to write tests that can be run in
-normal or "short" mode; short mode is now used by all.bash to reduce

-This week's release introduces a new release tagging scheme. We intend to
-continue with our weekly releases, but have renamed the existing tags from
-"release" to "weekly". The "release" tag will now be applied to one hand-picked
-stable release each month or two.
-
-The revision formerly tagged "release.2011-03-07.1" (now "weekly.2011-03-07.1")
-has been nominated our first stable release, and has been given the tag
-"release.r56". As we tag each stable release we will post an announcement to
-the new golang-announce mailing list:
-  http://groups.google.com/group/golang-announce
-
-You can continue to keep your Go installation updated using "hg update
-release", but now you should only need to update once we tag a new stable
-release, which we will announce here. If you wish to stay at the leading edge,
-you should switch to the weekly tag with "hg update weekly".
-
-
-This weekly release includes significant changes to the language spec and the
-http, os, and syscall packages. Your code may need to be changed. It also
-introduces the new gofix tool.
-
-The closed function has been removed from the language. The syntax for channel
-receives has been changed to return an optional second value, a boolean value
-indicating whether the channel is closed. This code:
-	v := &lt;-ch
-	if closed(ch) {
-		// channel is closed
-	}
-should now be written as:
-	v, ok := &lt;-ch
-	if !ok {
-		// channel is closed
-	}
-
-It is now illegal to declare unused labels, just as it is illegal to declare
-unused local variables.
-
-The new gofix tool finds Go programs that use old APIs and rewrites them to use
-newer ones.  After you update to a new Go release, gofix helps make the
-necessary changes to your programs. Gofix will handle the http, os, and syscall
-package changes described below, and we will update the program to keep up with
-future changes to the libraries.
-
-The Hijack and Flush methods have been removed from the http.ResponseWriter
-interface and are accessible via the new http.Hijacker and http.Flusher
-interfaces. The RemoteAddr and UsingTLS methods have been moved from
-http.ResponseWriter to http.Request.
-
-The http.ResponseWriter interface's SetHeader method has been replaced by a
-Header() method that returns the response's http.Header. Caller code needs to
-change. This code:
-	rw.SetHeader("Content-Type", "text/plain")
-should now be written as:
-	rw.Header().Set("Content-Type", "text/plain")
-The os and syscall packages' StartProcess functions now take their final three
-arguments as an *os.ProcAttr and *syscall.ProcAttr values, respectively. This
-code:
-	os.StartProcess(bin, args, env, dir, fds)
-should now be written as:
-	os.StartProcess(bin, args, &amp;os.ProcAttr{Files: fds, Dir: dir, Env: env})
-
-The gob package will now encode and decode values of types that implement the
-gob.GobEncoder and gob.GobDecoder interfaces. This allows types with unexported
-fields to transmit self-consistent descriptions; one instance is big.Int and
-big.Rat.
-
-Other changes:
-* 5l, 6l, 8l: reduce binary size about 40% by omitting symbols for type, string, go.string.
-* 5l, 8l: output missing section symbols (thanks Anthony Martin).

-This release includes changes to the http package and a small language change.
-Your code will require changes if it manipulates http Headers or omits the
-condition in if statements.

-<h2 id="2011-02-01">2011-02-01</h2>
-
-<pre>
-This release includes significant changes to channel operations and minor
-changes to the log package. Your code will require modification if it uses
-channels in non-blocking communications or the log package's Exit functions.
-
-Non-blocking channel operations have been removed from the language.
-The equivalent operations have always been possible using a select statement
-with a default clause.  If a default clause is present in a select, that clause
-will execute (only) if no other is ready, which allows one to avoid blocking on
-a communication.
-
-For example, the old non-blocking send operation,
-
-	if ch &lt;- v {
-		// sent
-	} else {
-		// not sent
-	}
-
-should be rewritten as,
-
-	select {
-	case ch &lt;- v:
-		// sent
-	default:
-		// not sent
-	}
-
-Similarly, this receive,
-
-	v, ok := &lt;-ch
-	if ok {
-		// received
-	} else {
-		// not received
-	}
-
-should be rewritten as,
-
-	select {
-	case v := &lt;-ch:
-		// received
-	default:
-		// not received
-	}
-
-This change is a prelude to redefining the 'comma-ok' syntax for a receive.
-In a later release, a receive expression will return the received value and an
-optional boolean indicating whether the channel has been closed. These changes
-are being made in two stages to prevent this semantic change from silently
-breaking code that uses 'comma-ok' with receives.
-There are no plans to have a boolean expression form for sends.
-
-Sends to a closed channel will panic immediately. Previously, an unspecified
-number of sends would fail silently before causing a panic.
-
-The log package's Exit, Exitf, and Exitln functions have been renamed Fatal,
-Fatalf, and Fatalln respectively. This brings them in line with the naming of
-the testing package. 
-
-The port to the "tiny" operating system has been removed. It is unmaintained
-and untested. It was a toy to show that Go can run on raw hardware and it
-served its purpose. The source code will of course remain in the repository
-history, so it could be brought back if needed later.
-
-This release also changes some of the internal structure of the memory
-allocator in preparation for other garbage collector changes. 
-If you run into problems, please let us know.
-There is one known issue that we are aware of but have not debugged yet:
-	http://code.google.com/p/go/issues/detail?id=1464&amp;.
-

-The json, gob, and template packages have changed, and code that uses them
-may need to be updated after this release. They will no longer read or write
-unexported struct fields. When marshaling a struct with json or gob the
-unexported fields will be silently ignored. Attempting to unmarshal json or
-gob data into an unexported field will generate an error. Accessing an
-unexported field from a template will cause the Execute function to return
-an error.
-
-Godoc now supports regular expression full text search, and this
-functionality is now available on golang.org.

-Package crypto/cipher has been started, to replace crypto/block.
-As part of the changes, rc4.Cipher's XORKeyStream method signature has changed from
-        XORKeyStream(buf []byte)
-to
-        XORKeyStream(dst, src []byte)
-to implement the cipher.Stream interface.  If you use crypto/block, you'll need
-to switch to crypto/cipher once it is complete.
-
-Package smtp's StartTLS now takes a *tls.Config argument.
-
-Package reflect's ArrayCopy has been renamed to Copy.  There are new functions
-Append and AppendSlice.
-
-The print/println bootstrapping functions now write to standard error.
-To write to standard output, use fmt.Print[ln].
-
-A new tool, govet, has been added to the Go distribution. Govet is a static
-checker for Go programs. At the moment, and for the foreseeable future,
-it only checks arguments to print calls.
-
-The cgo tool for writing Go bindings for C code has changed so that it no
-longer uses stub .so files (like cgo_stdio.so).  Cgo-based packages using the
-standard Makefiles should build without any changes.  Any alternate build
-mechanisms will need to be updated.
-
-The C and Go compilers (6g, 6c, 8g, 8c, 5g, 5c) now align structs according to
-the maximum alignment of the fields they contain; previously they aligned
-structs to word boundaries.  This may break non-cgo-based code that attempts to
-mix C and Go.
-
-NaCl support has been removed. The recent linker changes broke NaCl support
-a month ago, and there are no known users of it.
-If necessary, the NaCl code can be recovered from the repository history.
-
-* 5g/8g, 8l, ld, prof: fix output of 32-bit values (thanks Eoghan Sherry).

-* crypto/tls: use rand.Reader in cert generation example (thanks Anthony Martin).
-* dashboard: fix project tag filter.
-* debug/elf, debug/macho: add ImportedLibraries, ImportedSymbols.

-* godefs: guard against structs with pad fields
-* godoc: added textual search, to enable use -fulltext flag.

-This release includes some package changes. If you use the crypto/tls or
-go/parser packages your code may require changes.
-
-The crypto/tls package's Dial function now takes an additional *Config
-argument.  Most uses will pass nil to get the same default behavior as before.
-See the documentation for details:
-        http://golang.org/pkg/crypto/tls/#Config
-        http://golang.org/pkg/crypto/tls/#Dial
-
-The go/parser package's ParseFile function now takes a *token.FileSet as its
-first argument. This is a pointer to a data structure used to store
-position information. If you don't care about position information you
-can pass "token.NewFileSet()". See the documentation for details:
-        http://golang.org/pkg/go/parser/#ParseFile
-
-This release also splits the patent grant text out of the LICENSE file into a
-separate PATENTS file and changes it to be more like the WebM grant.
-These clarifications were made at the request of the Fedora project.
-
-Other changes:

-Several package changes in this release may require you to update your code if
-you use the bytes, template, or utf8 packages. In all cases, any outdated code
-will fail to compile rather than behave erroneously.
-
-The bytes package has changed. Its Add and AddByte functions have been removed,
-as their functionality is provided by the recently-introduced built-in function
-"append". Any code that uses them will need to be changed:
-s = bytes.Add(s, b)    -&gt;    s = append(s, b...)
-s = bytes.AddByte(b, c)    -&gt;    s = append(s, b)
-s = bytes.Add(nil, c)    -&gt;    append([]byte(nil), c)
-
-The template package has changed. Your code will need to be updated if it calls
-the HTMLFormatter or StringFormatter functions, or implements its own formatter
-functions. The function signature for formatter types has changed to:
-        func(wr io.Writer, formatter string, data ...interface{})
-to allow multiple arguments to the formatter.  No templates will need updating.
-See the change for examples:
-        http://code.google.com/p/go/source/detail?r=2c2be793120e
-
-The template change permits the implementation of multi-word variable
-instantiation for formatters. Before one could say
-        {field}
-or
-        {field|formatter}
-Now one can also say
-        {field1 field2 field3}
-or
-        {field1 field2 field3|formatter}
-and the fields are passed as successive arguments to the formatter,
-by analogy to fmt.Print.
-
-The utf8 package has changed. The order of EncodeRune's arguments has been
-reversed to satisfy the convention of "destination first".
-Any code that uses EncodeRune will need to be updated.
-
-Other changes:
-* [68]l: correct dwarf location for globals and ranges for arrays.
-* big: fix (*Rat) SetFrac64(a, b) when b &lt; 0 (thanks Eoghan Sherry).
-* compress/flate: fix typo in comment (thanks Mathieu Lonjaret).
-* crypto/elliptic: use a Jacobian transform for better performance.
-* doc/code.html: fix reference to "gomake build" (thanks Anschel Schaffer-Cohen).
-* doc/roadmap: update gdb status.
-* doc/spec: fixed some omissions and type errors.
-* doc: some typo fixes (thanks Peter Mundy).
-* exp/eval: build fix for parser.ParseFile API change (thanks Anschel Schaffer-Cohen).
-* fmt: Scan accepts Inf and NaN,
-        allow "% X" as well as "% x".
-* go/printer: preserve newlines in func parameter lists (thanks Jamie Gennis).
-* http: consume request body before next request.
-* log: ensure writes are atomic (thanks Roger Peppe).
-* path: Windows support for Split (thanks Benny Siegert).
-* runtime: fix SysFree to really free memory on Windows (thanks Alex Brainman),
-        parallel definitions in Go for all C structs.
-* sort: avoid overflow in pivot calculation,
-        reduced stack depth to lg(n) in quickSort (thanks Stefan Nilsson).
-* strconv: Atof on Infs and NaNs.

-*** This release changes the encoding used by package gob. 
-    If you store gobs on disk, see below. ***
-
-The ARM port (5g) now passes all tests. The optimizer is not yet enabled, and
-floating point arithmetic is performed entirely in software. Work is underway
-to address both of these deficiencies.
-
-The syntax for arrays, slices, and maps of composite literals has been
-simplified. Within a composite literal of array, slice, or map type, elements
-that are themselves composite literals may elide the type if it is identical to
-the outer literal's element type. For example, these expressions:
-	[][]int{[]int{1, 2, 3}, []int{4, 5}}
-	map[string]Point{"x": Point{1.5, -3.5}, "y": Point{0, 0}}
-can be simplified to:
-	[][]int{{1, 2, 3}, {4, 5}}
-	map[string]Point{"x": {1.5, -3.5}, "y": {0, 0}}
-Gofmt can make these simplifications mechanically when invoked with the 
-new -s flag.
-
-The built-in copy function can now copy bytes from a string value to a []byte.
-Code like this (for []byte b and string s): 
-	for i := 0; i &lt; len(s); i++ {
-		b[i] = s[i]
-	}
-can be rewritten as:
-	copy(b, s)
-
-The gob package can now encode and decode interface values containing types
-registered ahead of time with the new Register function. These changes required
-a backwards-incompatible change to the wire format.  Data written with the old
-version of the package will not be readable with the new one, and vice versa.
-(Steps were made in this change to make sure this doesn't happen again.) 
-We don't know of anyone using gobs to create permanent data, but if you do this
-and need help converting, please let us know, and do not update to this release
-yet.  We will help you convert your data.
-
-Other changes:
-* 5g, 6g, 8g: generate code for string index instead of calling function.
-* 5l, 6l, 8l: introduce sub-symbols.
-* 6l/8l: global and local variables and type info.
-* Make.inc: delete unnecessary -fno-inline flag to quietgcc.
-* arm: precise float64 software floating point, bug fixes.
-* big: arm assembly, faster software mulWW, divWW.
-* build: only print "You need to add foo to PATH" when needed.
-* container/list: fix Remove bug and use pointer to self as identifier.
-* doc: show page title in browser title bar,
-        update roadmap.
-* encoding/binary: give LittleEndian, BigEndian specific types.
-* go/parser: consume auto-inserted semi when calling ParseExpr().
-* gobuilder: pass GOHOSTOS and GOHOSTARCH to build,
-        write build and benchmarking logs to disk.
-* goinstall: display helpful message when encountering a cgo package,
-        fix test for multiple package names (thanks Fazlul Shahriar).
-* gotest: generate correct gofmt-formatted _testmain.go.
-* image/png: speed up paletted encoding ~25% (thanks Brad Fitzpatrick).
-* misc: update python scripts to specify python2 as python3 is now "python".
-* net: fix comment on Dial to mention unix/unixgram.
-* rpc: expose Server type to allow multiple RPC Server instances.
-* runtime: print unknown types in panic.
-* spec: append built-in (not yet implemented).
-* src: gofmt -s -w src misc.
-        update code to use copy-from-string.
-* test/bench: update numbers.
-* websocket: fix short Read.

-This release includes changes to the log package, the removal of exp/iterable,
-two new tools (gotry and goplay), one small language change, and many other
-changes and fixes.  If you use the log or iterable packages, you need to make
-changes to your code.
-
-The log package has changed.  Loggers now have only one output, and output to
-standard error by default.  The names have also changed, although the old names
-are still supported.  They will be deleted in the next release, though, so it
-would be good to update now if you can.  For most purposes all you need to do
-is make these substitutions:
-        log.Stderr -&gt; log.Println or log.Print
-        log.Stderrf -&gt; log.Printf
-        log.Crash -&gt; log.Panicln or log.Panic
-        log.Crashf -&gt; log.Panicf
-        log.Exit -&gt; log.Exitln or log.Exit
-        log.Exitf -&gt; log.Exitf (no change)
-Calls to log.New() must drop the second argument.
-Also, custom loggers with exit or panic properties will need to be reworked.
-For full details, see the change description:
-        http://code.google.com/p/go/source/detail?r=d8a3c7563d
-
-The language change is that uses of pointers to interface values no longer
-automatically dereference the pointer.  A pointer to an interface value is more
-often a beginner's bug than correct code.
-
-The package exp/iterable has been removed. It was an interesting experiment,
-but it encourages writing inefficient code and has outlived its utility.
-
-The new tools:
-* gotry: an exercise in reflection and an unusual tool. Run 'gotry' for details.
-* goplay: a stand-alone version of the Go Playground. See misc/goplay.
-
-Other changes:
-* 6l: Mach-O fixes, and fix to work with OS X nm/otool (thanks Jim McGrath).
-* [568]a: correct line numbers for statements.
-* arm: code generation and runtime fixes,
-	adjust recover for new reflect.call,
-	enable 6 more tests after net fix.
-* big: fix panic and round correctly in Rat.FloatString (thanks Anthony Martin).
-* build: Make.cmd: remove $(OFILES) (thanks Eric Clark),
-        Make.pkg: remove .so before installing new one,
-        add GOHOSTOS and GOHOSTARCH environment variables.
-* crypto/tls: better error messages for certificate issues,
-        make SetReadTimeout work.
-* doc: add Sydney University video,
-	add The Expressiveness of Go talk.
-* exp/draw/x11: support X11 vendors other than "The X.Org Foundation".
-* expvar: add (*Int).Set (thanks Sam Thorogood).
-* fmt: add Errorf helper function,
-        allow %d on []byte.
-* gc: O(1) string comparison when lengths differ,
-        various bug fixes.

-* ld: be less picky about bad line number info.
-* misc/cgo/life: fix for new slice rules (thanks Graham Miller).
-* net: allow _ in DNS names.
-* netchan: export before import when testing, and
-        zero out request to ensure correct gob decoding. (thanks Roger Peppe).
-* os: make tests work on windows (thanks Alex Brainman).
-* runtime: bug fix: serialize mcache allocation,
-        correct iteration of large map values,
-        faster strequal, memequal (thanks Graham Miller),
-        fix argument dump in traceback,
-        fix tiny build.
-* smtp: new package (thanks Evan Shaw).

-This release includes some minor language changes and some significant package
-changes. You may need to change your code if you use ...T parameters or the
-http package.
-
-The semantics and syntax of forwarding ...T parameters have changed.
-        func message(f string, s ...interface{}) { fmt.Printf(f, s) }
-Here, s has type []interface{} and contains the parameters passed to message.
-Before this language change, the compiler recognized when a function call
-passed a ... parameter to another ... parameter of the same type, and just
-passed it as though it was a list of arguments.  But this meant that you
-couldn't control whether to pass the slice as a single argument and you
-couldn't pass a regular slice as a ... parameter, which can be handy.  This
-change gives you that control at the cost of a few characters in the call.
-If you want the promotion to ...,  append ... to the argument:
-        func message(f string, s ...interface{}) { fmt.Printf(f, s...) }
-Without the ..., s would be passed to Printf as a single argument of type
-[]interface{}.  The bad news is you might need to fix up some of your code, 
-but the compiler will detect the situation and warn you.
-
-Also, the http.Handler and http.HandlerFunc types have changed. Where http
-handler functions previously accepted an *http.Conn, they now take an interface
-type http.ResponseWriter. ResponseWriter implements the same methods as *Conn,
-so in most cases the only change required will be changing the type signature
-of your handler function's first parameter. See:
-  http://golang.org/pkg/http/#Handler
-
-The utf8 package has a new type, String, that provides efficient indexing 
-into utf8 strings by rune (previously an expensive conversion to []int 
-was required). See:
-  http://golang.org/pkg/utf8/#String
-
-The compiler will now automatically insert a semicolon at the end of a file if
-one is not found. This effect of this is that Go source files are no longer
-required to have a trailing newline.
-
-Other changes:
-* 6prof: more accurate usage message.
-* archive/zip: new package for reading Zip files.
-* arm: fix code generation, 10 more package tests pass.
-* asn1: make interface consistent with json.
-* bufio.UnreadRune: fix bug at EOF.

-This release includes changes to the build system that will likely require you
-to make changes to your environment variables and Makefiles.
-
-All environment variables are now optional:
- - $GOOS and $GOARCH are now optional; their values should now be inferred 
-   automatically by the build system,
- - $GOROOT is now optional, but if you choose not to set it you must run
-   'gomake' instead of 'make' or 'gmake' when developing Go programs
-   using the conventional Makefiles,
- - $GOBIN remains optional and now defaults to $GOROOT/bin;
-   if you wish to use this new default, make sure it is in your $PATH
-   and that you have removed the existing binaries from $HOME/bin.
-
-As a result of these changes, the Go Makefiles have changed. If your Makefiles
-inherit from the Go Makefiles, you must change this line:
-    include ../../Make.$(GOARCH)
-to this:
-    include ../../Make.inc
-
-This release also removes the deprecated functions in regexp and the 
-once package. Any code that still uses them will break.
-See the notes from the last release for details:
-    http://golang.org/doc/devel/release.html#2010-08-11
-
-Other changes:
-* 6g: better registerization for slices, strings, interface values

-This release introduces some package changes. You may need to change your
-code if you use the once, regexp, image, or exp/draw packages.
-
-The type Once has been added to the sync package. The new sync.Once will
-supersede the functionality provided by the once package. We intend to remove
-the once package after this release. See:
-    http://golang.org/pkg/sync/#Once
-All instances of once in the standard library have been replaced with
-sync.Once. Reviewing these changes may help you modify your existing code. 
-The relevant changeset:
-    http://code.google.com/p/go/source/detail?r=fa2c43595119
-
-A new set of methods has been added to the regular expression package, regexp.
-These provide a uniformly named approach to discovering the matches of an
-expression within a piece of text; see the package documentation for details: 
-    http://golang.org/pkg/regexp/
-These new methods will, in a later release, replace the old methods for
-matching substrings.  The following methods are deprecated:
-    Execute (use FindSubmatchIndex)
-    ExecuteString (use FindStringSubmatchIndex)
-    MatchStrings(use FindStringSubmatch)
-    MatchSlices (use FindSubmatch)
-    AllMatches (use FindAll; note that n&lt;0 means 'all matches'; was n&lt;=0)
-    AllMatchesString (use FindAllString; note that n&lt;0 means 'all matches'; was n&lt;=0)
-(Plus there are ten new methods you didn't know you wanted.) 
-Please update your code to use the new routines before the next release.
-
-An image.Image now has a Bounds rectangle, where previously it ranged 
-from (0, 0) to (Width, Height). Loops that previously looked like:
-    for y := 0; y &lt; img.Height(); y++ {
-        for x := 0; x &lt; img.Width(); x++ {
-            // Do something with img.At(x, y)
-        }
-    }
-should instead be:
-    b := img.Bounds()
-    for y := b.Min.Y; y &lt; b.Max.Y; y++ {
-        for x := b.Min.X; x &lt; b.Max.X; x++ {
-            // Do something with img.At(x, y)
-        }
-    }
-The Point and Rectangle types have also moved from exp/draw to image.
-
-Other changes:
-* arm: bugfixes and syscall (thanks Kai Backman).
-* asn1: fix incorrect encoding of signed integers (thanks Nicholas Waples).
-* big: fixes to bitwise functions (thanks Evan Shaw).

-This release includes some package changes that may require changes to 
-client code.
-
-The Split function in the bytes and strings packages has been changed.
-The count argument, which limits the size of the return, previously treated
-zero as unbounded. It now treats 0 as 0, and will return an empty slice.  
-To request unbounded results, use -1 (or some other negative value).
-The new Replace functions in bytes and strings share this behavior.
-This may require you change your existing code.
-
-The gob package now allows the transmission of non-struct values at the
-top-level. As a result, the rpc and netchan packages have fewer restrictions
-on the types they can handle.  For example, netchan can now share a chan int.
-
-The release also includes a Code Walk: "Share Memory By Communicating".
-It describes an idiomatic Go program that uses goroutines and channels:
-	http://golang.org/doc/codewalk/sharemem/
-
-There is now a Projects page on the Go Dashboard that lists Go programs, 
-tools, and libraries:
-	http://godashboard.appspot.com/project
-
-Other changes:
-* 6a, 6l: bug fixes.
-* bytes, strings: add Replace.

-This release contains three language changes:
-
-1. Accessing a non-existent key in a map is no longer a run-time error.  
-It now evaluates to the zero value for that type.  For example:
-        x := myMap[i]   is now equivalent to:   x, _ := myMap[i]
-
-2. It is now legal to take the address of a function's return value.  
-The return values are copied back to the caller only after deferred
-functions have run.
-
-3. The functions panic and recover, intended for reporting and recovering from
-failure, have been added to the spec:
-	http://golang.org/doc/go_spec.html#Handling_panics 
-In a related change, panicln is gone, and panic is now a single-argument
-function.  Panic and recover are recognized by the gc compilers but the new
-behavior is not yet implemented.
-
-The ARM build is broken in this release; ARM users should stay at release.2010-03-22.
-
-Other changes:
-* bytes, strings: add IndexAny.

-There are two small language changes: the meaning of chan &lt;- chan int
-is now defined, and functions returning functions do not need to 
-parenthesize the result type.
-
-There is one significant implementation change: the compilers can
-handle multiple packages using the same name in a single binary.
-In the gc compilers, this comes at the cost of ensuring that you
-always import a particular package using a consistent import path.
-In the gccgo compiler, the cost is that you must use the -fgo-prefix
-flag to pass a unique prefix (like the eventual import path).

-Since the last release there has been one large syntactic change to
-the language, already discussed extensively on this list: semicolons
-are now implied between statement-ending tokens and newline characters.
-See http://groups.google.com/group/golang-nuts/t/5ee32b588d10f2e9 for
-details.
-
-By default, gofmt now parses and prints the new lighter weight syntax.
-To convert programs written in the old syntax, you can use:
-
-	gofmt -oldparser -w *.go
-
-Since everything was being reformatted anyway, we took the opportunity to
-change the way gofmt does alignment.  Now gofmt uses tabs at the start
-of a line for basic code alignment, but it uses spaces for alignment of
-interior columns.  Thus, in an editor with a fixed-width font, you can
-choose your own tab size to change the indentation, and no matter what
-tab size you choose, columns will be aligned properly.
-
-
-In addition to the syntax and formatting changes, there have been many
-smaller fixes and updates:
-
-6g,8g,5g: many bug fixes, better registerization,
-   build process fix involving mkbuiltin (thanks Yongjian Xu),
-   method expressions for concrete types

-Since the last release there are two changes to the language: 
-
-* new builtin copy(dst, src) copies n = min(len(dst), len(src)) 
-  elements to dst from src and returns n.  It works correctly

-  Convert your programs using: 
-      gofmt -w -r 'bytes.Copy(d, s) -&gt; copy(d, s)' *.go 
-
-* new syntax x[lo:] is shorthand for x[lo:len(x)].
