<h1>Release Notes for Ext JS 4.2.1</h1>
<p class="notes">
Release Date: May 16, 2013<br>
Version Number: 4.2.1.883
</p>
<h2>General</h2>
<p>The final release of Ext JS 4.2.1 contains numerous fixes and small
enhancements requested by customers and the community. While the
details are below, there are several items worth calling out.
<h3>New Big Data Example</h3>
<p>The new
<a href="http://docs.sencha.com/extjs/4.2.1/extjs-build/examples/build/KitchenSink/ext-theme-neptune/">
Big Data example</a> shows off all of the major grid features
and plugins working together in a single grid. It also shows off a
text field in a grid column header! Head over and check it out!
<h3>Sencha Cmd 3.1.2</h3>
<p>To coincide with this release, Sencha Cmd 3.1.2 is also now available.
The primary change with regards to Cmd is that the packages produced
by Ext JS now stay inside the "ext" folder when you generate a new
application or workspace. The "ext-*" packages previous saved to your
"packages" folder can be removed. For details see the
<a href="http://cdn.sencha.com/cmd/3.1.2.342/release-notes.html">release notes
for Sencha Cmd 3.1.2</a>. If you are using Sencha Cmd, it is
recommended that you upgrade to the new version.
<h3>Locale Package Consolidation</h3>
<p>In Ext JS 4.2.0 we migrated the locale files in to Sencha Cmd packages
to facilitate switching between locales. The downside is that this
produced a lot of small packages that needed to be required in your
<tt>"app.json"</tt> (or used as pure JS files). As an enhancement to
this process in Ext JS 4.2.1 we have consolidated all of the locales
into the <tt>ext-locale</tt> package. The legacy file paths are still
preserved, but if you are using locale packages, you can now just do
this in your <tt>"app.json"</tt> file:
<pre>"requires": [
'ext-locale'
]</pre>
<p>You will still need to set <tt>app.locale</tt> to pick up the proper
locale overrides. They are just all located in the one package in
this release.
