		<h2 id="overview">Package Contents</h2>
		<p>
			<b>Vaadin</b> is a Java framework for building modern web
			applications that look great, perform well and make you and your
			users happy. <b>Vaadin</b> is available under the Apache 2 license
			(see license.html).
		</p>
		<p>
			<b>Vaadin</b> is distributed as a single JAR file. Inside the JAR you
			will find:
			<ul>
				<li>Vaadin server and client side classes (/com)</li>
				<li>Vaadin server and client side sources (/com)</li>
				<li>The default widget set (/VAADIN/widgetsets)</li>
				<li>Themes: Runo, Reindeer and Chameleon (/VAADIN/themes)</li>
				<li>Release notes (/release-notes.html)</li>
				<li>Licensing information (/license.html)</li>
			</ul>
		</p>

		<h2 id="security-fixes">Security fixes in Vaadin @version@</h2>
		<p>Vaadin @version@ incorporates fixes for the following security issues:</p>
    <ul>
        <li><a href="http://dev.vaadin.com/ticket/7669">#7669</a> CSRF/XSS vulnerability through separator injection</li>
        <li><a href="http://dev.vaadin.com/ticket/7670">#7670</a> Directory traversal vulnerability</li>
        <li><a href="http://dev.vaadin.com/ticket/7671">#7671</a> Contributory XSS: Possibility to inject HTML/JavaScript in system error messages</li>
        <li><a href="http://dev.vaadin.com/ticket/7672">#7672</a> Contributory XSS: possibility for injection in certain components</li>
    </ul>

		<p>
		These issue were discovered by Wouter Coekaerts (<a href="http://wouter.coekaerts.be/">http://wouter.coekaerts.be/</a>) and an internal review.
		Immediate upgrade to a version containing the fixes (6.6.7 or later or 6.7.0 or later) is strongly recommended for all users.
		</p>

		<p>
		The most serious of these issues is the directory traversal attack that can allow read access to the class files of an application as well as some configuration information. 
		</p> 

		<p>
		If unable to immediately upgrade Vaadin to a version containing the fixes, the directory traversal vulnerability can be mitigated by not mapping the context path
		"/VAADIN" to a Vaadin servlet in web.xml but instead deploying such static resources (themes and widgetsets) directly on the server and serving them as files. 
		</p>

		<p>
		The other vulnerabilities typically require user actions (pasting text crafted by the attacker into the application or following a link crafted by the attacker)
		for a successful attack, but may be exploitable more directly in certain applications. They can allow the attacker to control the user session for the application
		in the browser.
		</p>
    
		<h2 id="enhancements">Enhancements in Vaadin @version@</h2>
		<p>
			<b>SQLContainer</b>
		</p>
		<p>SQLContainer connects your application to an SQL database using
			JDBC. SQLContainer allows you to easily bind data stored in a SQL
			database to Table and Select components, as well as edit the data
			using Forms. Compared to many object-relational tools this provides
			you with fast, low-level database access.</p>
		<p>SQLContainer was previously distributed as an add-on and has
			now been integrated into the framework.</p>
		<p>
			<b>TreeTable</b>
		</p>
		<p>TreeTable is an extended Table component that can show
			hierarchical structures in its first column. Users can show or hide
			children from a small icon before the actual column value in the
			first column.</p>
		<p>TreeTable is, similarly to Table, designed to scale well with
			large number of rows by only sending the needed rows to the browser.
			With the Collapsible Container extension, a developer can build the
			data provider so that it does not consume too much memory on the
			server side either.</p>
		<p>
			<b>Chameleon Theme</b>
		</p>
		<p>Chameleon Theme provides a completely new look and feel for
			your application.</p>
		<p>
			The theme is built on top of the Vaadin Base theme and tries to keep
			out of the way where appropriate, so small modifications are easy to
			do with CSS.
			<p>
				The theme contains several different useful styles for many of the
				basic components like <i>big</i> and <i>warning</i> for a Label. You
				can even combine many styles together, like <i>big warning</i>
			</p>
			If the default color scheme does not suit your taste, feel free to
			use the online color scheme editor at <a
				href="http://demo.vaadin.com/">http://demo.vaadin.com</a> to build a
			customized theme.You can also change the base font size for the whole
			theme with the same editor.
			<p>
				<i>Note that the theme is intentionally simplified for some
					browsers, most notably old Internet Explorer versions.</i>
			</p>
		</p>
		<p>
			<b>Notification</b> now supports a plain text mode for its contents
		</p>
		<p>
			<b>OptionGroup</b> now supports a HTML mode for the item captions
		</p>
        <p>
            <b>OptionGroup</b> now supports item icons
        </p>

		</p>
		<p>
			<b>ComboBox</b> now supports scrolling using the mouse wheel
		</p>
		<p>
			<b>Table ColumnGenerator</b> can now generate plain text in addition
			to Components
		</p>
		<p>
			<b>TabSheet</b> tabs can be styled individually
		</p>
		<p>
			<b>Button</b> can be automatically disabled when clicked
		</p>
		<p>
			<b>Tree, Table</b> and <b>TreeTable</b> support tooltips for
			individual items or cells
		</p>
		<p>
			<b>Table</b> and <b>TreeTable</b> now support GeneratedRows that can
			be used for grouping or summary rows
		</p>
		<p>
			<b>TreeTable</b> supports animation for expand and collapse
			operations
		</p>
		<p>
			<b>TreeTable</b> supports expand and collapse listeners
		</p>
		<p>
			<b>PopupDateField</b> and <b>InlineDateField</b> now support time
			zones
		</p>
        <p>
            <b>ComboBox</b> can now be used as a replacement for NativeSelect
        </p>
        <p>
            <b>Audio</b> and <b>Video</b> components implement support for HTML5 &lt;audio&gt; and &lt;video&gt; elements.
        </p>
        <p>
            <b>CDI</b> can now also be used with @SessionScoped beans.
        </p>
		<p>
			<b>Sampler</b> is no longer distributed as part of Vaadin @version@.
			It will be available as a separate download
		</p>
		<p>
			<b>Book of Vaadin</b> is no longer distributed with Vaadin @version@.

		<h2 id="backwardsincompatibilities">Backwards incompatible
			changes in Vaadin @version@</h2>
		<p>Table.ColumnGenerator.generateCell has been changed to return
			Object instead of Component to enable generation of plain text.</p>
		<p>Package names for SQLContainer, TreeTable and Chameleon Theme
			java files have been changed from com.vaadin.addons.* to com.vaadin.*</p>
		</p>
		<p>If you have been using SQLContainer, TreeTable or Chameleon
			Theme as add-ons, remove the add-on jars from the project.</p>
		<p>The DOM structure of Forms without descriptions has changed, which means
		    that any TestBench scripts testing this kind of Form need to be updated.
		    If your tests start failing, subtract one from the index in the test script,
		    e.g. change
		    <pre class="codeblock">VForm[0]/domChild[0]/domChild[3]</pre>
		    into
		    <pre class="codeblock">VForm[0]/domChild[0]/domChild[2]</pre>
		    and your tests will pass again.</p>

		<h2 id="dependencies">Vaadin @version@ dependencies</h2>
		Vaadin uses GWT @gwt-version@ for widget set compilation. GWT can be
		downloaded from <a href="http://code.google.com/webtoolkit/">http://code.google.com/webtoolkit/</a>.
		GWT can also be automatically downloaded by the Vaadin Plug-in for
		Eclipse. Please note that GWT @gwt-version@ requires the <i>validation-api-1.0.0.GA.jar</i>
		and <i>validation-api-1.0.0.GA-sources.jar</i> files in addition to <i>gwt-dev.jar</i>
		and <i>gwt-user.jar</i> for widget set compilation.

		<h2 id="upgrading">Upgrading to Vaadin @version-minor@</h2>
		<p>
			When upgrading from an earlier Vaadin version, you must
			<ul>
				<li>Recompile your classes using the new Vaadin JAR. Binary
					compatibility is only guaranteed for maintenance releases of
					Vaadin.</li>
				<li>Recompile any add-ons you have created using the new Vaadin
					JAR.</li>
				<li>Recompile your widget set using the new Vaadin JAR and the
					newly compiled add-ons.</li>
				<li>If you have extracted a theme from the Vaadin JAR, you need
					to update it with the theme provided in the new Vaadin JAR.</li>
			</ul>
		</p>
		<p>Remember also to refresh the project in your IDE to ensure that
			the new version of everything is in use.</p>
		<p>Using the "?debug" URL parameter you can verify that the
			version of the servlet (JAR), the theme and the widgetset all match.</p>
		<p>
			<b>Eclipse</b> users should always check if there is a new version of
			the Eclipse Plug-in available. The Eclipse Plug-in can be used to
			update the Vaadin version in the project (Project properties &raquo;
			Vaadin).
		</p>

		<p>
			<b>Maven</b> users should update the Vaadin dependency version in the
			<tt>pom.xml</tt>
			unless it is defined as
			<tt>LATEST</tt>
			. You must also ensure that the GWT dependency uses the correct
			version and recompile your project and your widget set.

		</p>

		<b>Liferay and other portal</b> users must install the new
		vaadin-@version@.jar as
		<t>ROOT/WEB-INF/lib/vaadin.jar</b> in the portal. Additionally the
		contents of the <tt>VAADIN</tt> folder from the JAR must be extracted
		to the <tt>ROOT/html/VAADIN</tt> directory in the Liferay
		installation. If your portal uses custom widgets, install the latest
		version of <a
			href="http://vaadin.com/directory#addon/vaadin-control-panel-for-liferay">Vaadin
			Control Panel for Liferay</a> for easy widget set compilation.

		<h3>Upgrading from Vaadin 6.5 or earlier</h3>
		If you are upgrading from 6.5.x or earlier, notice that Vaadin
		@version@ uses GWT @gwt-version@. Upgrade your dependencies as
		necessary. See <a href="#dependencies">the dependencies</a> section
		for more information.
		</p>

		<h3 id="widgetupgrade">Upgrading from Vaadin 6.1 or earlier</h3>

		<p>
			The way widget sets are created was completely changed in Vaadin 6.2.
			Existing projects, where custom widgets (a custom widget set) are
			used, must be migrated when upgrading to Vaadin 6.2 or later.
			Projects where the default widget set is used do not need migration.
			See <a
				href="http://vaadin.com/download/release/6.2/6.2.0/release-notes.html">Vaadin
				6.2.0 release notes</a> for more details.

		<h3 id="knownissues">Known problems and limitations in Vaadin
			@version@</h3>

		<ul>
			<li><p id="zipissue">
					<a href="http://dev.vaadin.com/ticket/1155">#1155</a>:
					Uncompressing the installation package fails in Windows if using
					the default Zip uncompression. Uncompression gives (in Windows
					Vista) an error message about too long filenames, and a more
					obscure message in other versions of Windows. Workaround: use <a
						href="http://www.7-zip.org/">7-Zip</a> or some other good unzip
					program for Windows.
				</p>
			</li>
		</ul>
		<h4 id="gae">Notes and Limitations for Google App Engine</h4>

		<p>The following instructions and limitations apply when you run a
			Vaadin application under the Google App Engine.</p>

		<ul>
			<li><p>
					Applications must use <b>GAEApplicationServlet</b> instead of <b>ApplicationServlet</b>
					in
					<tt>web.xml</tt>
					.
				</p>
			</li>

			<li><p>
					Session support must be enabled in
					<tt>appengine-web.xml</tt>
					:
				</p> <pre>    &lt;sessions-enabled&gt;true&lt;/sessions-enabled&gt;</pre>
			</li>

			<li><p>Avoid using the session for storage, usual App Engine
					limitations apply (no synchronization, i.e, unreliable).</p>
			</li>

			<li><p>
					Vaadin uses memcache for mutex, the key is of the form
					<tt>_vmutex&lt;sessionid&gt;</tt>
					.
				</p>
			</li>

			<li><p>
					The Vaadin <b>WebApplicationContext</b> class is serialized
					separately into memcache and datastore; the memcache key is
					<tt>_vac&lt;sessionid&gt;</tt>
					and the datastore entity kind is
					<tt>_vac</tt>
					with identifiers of the type
					<tt>_vac&lt;sessionid&gt;</tt>
					.
				</p>
			</li>

			<li><p>
					DO NOT update application state when serving an <b>ApplicationResource</b>
					(e.g <b>ClassResource</b>.<i>getStream()</i>).
				</p>
			</li>

			<li><p>
					AVOID (or be very careful when) updating application state in a <b>TransactionListener</b>
					or a <b>HttpServletRequestListener</b> - they are called even when
					the application is not locked and won't be serialized (e.g <b>ApplicationResource</b>),
					and changes can thus go missing (it should be safe to update things
					that can be safely discarded later - i.e valid only for the current
					request)
				</p>
			</li>

			<li><p>The application remains locked during uploads - a
					progress bar is not possible</p>
			</li>
		</ul>
