<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="http://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.
