<h2>Release Notes for Vaadin @version@</h2>
<p>Vaadin @version@ is the first release of Vaadin, the next generation of the framework
formerly known as IT Mill Toolkit. The major release includes a number of enhancements to
IT Mill Toolkit 5.4, along with many bug fixes. The most significant additions are:</p>
<ul>
<li>Vaadin Plugin for the Eclipse IDE</li>
<li>Preview version of a WYSIWYG Editor (under Eclipse)</li>
</ul>
<p>Some other notable changes:</p>
<ul>
<li>State (caption, hidden, disabled) of a tab in a <b>TabSheet</b> is no longer bound to the contained component, though the initial state is obtained from the component (<a href="http://dev.itmill.com/ticket/2914">#2914</a>).</li>
<li><b>FieldFactory</b> has been split into <b>FormFieldFactory</b> and <b>TableFieldFactory</b>, both containing a single method (<a href="http://dev.itmill.com/ticket/2956">#2956</a>, <a href="http://dev.itmill.com/ticket/2499">#2499</a>).</li>
<li>The <b>Form</b> component previously called two methods in <b>FieldFactory</b>. Now it always calls only one in <b>FormFieldFactory</b></li>
<li><b>Panel</b> and <b>Window</b> can now contain a <b>ComponentContainer</b> as the "root layout" (previously only Layout) (<a href="http://dev.itmill.com/ticket/2921">#2921</a>). This should not require changes to user code.</li>
</ul>
<p>The first three changes are not backward-compatible with IT Mill Toolkit 5.4.</p>
<h2>Instructions for Upgrading from IT Mill Toolkit 5</h2>
<p>While the Vaadin 6 API is otherwise mostly backward-compatible with IT Mill Toolkit 5.4, the
change of the product name has made it necessary to reflect it in the Java package names,
some name prefixes, and some other details.</p>
<h3>Server-side Upgrade Instructions</h3>
<ul>
<li>Java Package names have changed:</li>
<ul>
<li>In all Java files using IT Mill Toolkit, rename package prefix <tt>com.itmill.toolkit</tt> → <tt>com.vaadin</tt></li>
<li>You also need to update the <tt>web.xml</tt> deployment descriptor:</li>
<ul>
<li>The servlet class is now <b>com.vaadin.terminal.gwt.server.ApplicationServlet</b>.</li>
</ul>
</ul>
<li>Changes in themes:
<ul>
<li>Rename <tt>WebContent/ITMILL</tt> → <tt>WebContent/VAADIN</tt></li>
<ul>
<li>If you have extracted the built-in themes and widgetsets in IT Mill Toolkit JAR to the folder to have them served statically by the server, remove the old content and re-extract from Vaadin JAR.</li>
<li>This may require changes to build scripts for custom widgetsets, as well as to any code that relies on the old naming (it is discouraged but possible).</li>
</ul>
<li>The new "<tt>reindeer</tt>" theme is the default theme in Vaadin; the old
"<tt>default</tt>" theme in IT Mill Toolkit 5 has been renamed as "<tt>runo</tt>"</li>
<ul>
<li>There is no longer a theme with name "<tt>default</tt>"</li>
<li>In your custom theme, replace:
<table><tr><td></td><td><tt>@import "../default/styles.css";</tt></td></tr>
<tr><td align="right">→</td><td><tt>@import "../reindeer/styles.css";</tt></td><td>if you wish to use the new default theme,</td></tr>
<tr><td align="right">or →</td><td><tt>@import "../runo/styles.css";</tt></td><td>if you wish to use the old default theme.</td></tr></table></li>
<li>Use the new default theme with <tt>setTheme("reindeer")</tt> and the old one with <tt>setTheme("runo")</tt>.</li>
</ul>
<li>CSS class names now start with "<tt>v-</tt>" prefix instead of "<tt>i-</tt>"</li>
<ul>
<li>Search and replace "<tt>.i-</tt>" → "<tt>.v-</tt>" in custom themes </li>
</ul>
</ul>
<li>Embedding Vaadin applications in web pages:</li>
<ul>
<li>The name of the JavaScript variable used for launching applications has changed from "<tt>itmill.toolkitConfigurations</tt>" → "<tt>vaadin.vaadinConfigurations</tt>"</li>
</ul>
</ul>
<h3>Client-side Upgrade Instructions</h3>
<p>The following changes are relevant only if you have developed or integrated custom
client-side widgets with Google Web Toolkit (GWT).</p>
<ul>
<li>GWT 1.6 is required for compiling custom widgets (optional)</li>
<ul>
<li>You need to upgrade GWT</li>
<li>The GWT Compiler class name has changed:</li>
<ul>
<li>Replace <tt>com.google.gwt.dev.GWTCompiler</tt> → <tt>com.google.gwt.dev.Compiler</tt> in your widget set build script (Ant) or launch configuration (Eclipse).</li>
</ul>
<li><i>Possible problems when building widgetset using Windows and JDK 1.5</i>. See <a href="#known-problems">Known Problems</a> #2891 below.</li>
</ul>
<li>The "<b>I</b>" (IT Mill) prefix in client-side widget classes has been changed to "<b>V</b>" (Vaadin), for example: <b>IButton</b> → <b>VButton</b>.</li>
<li>Rename <b>IToolkitOverlay</b> → <b>VOverlay</b>
</ul>
<h2>Package for the experimental GWT Out-of-Process Hosted Mode</h2>
<p>We provide a separate (platform independent) installation package
(<tt>vaadin-oophm-<version></version>.tar.gz</tt>) for the
experimental Out of Process Hosted Mode (OOPHM) of GWT, which allows
debugging client-side code in GWT Hosted Mode with a regular web
browser. Using the OOPHM requires installing a browser plugin (available
for Mozilla Firefox, IE, and WebKit). See the manual section on OOPHM
for more details.</p>
<p>The Linux version of GWT Hosted Mode Browser is no longer compatible with Vaadin (<a
href="http://dev.itmill.com/ticket/2299">#2299</a>), so the OOPHM is the only option for
debugging in hosted mode in Linux.</p>
<p>The compilation of OOPHM widget sets uses a large amount of stack memory, so if the
JVM default is too small, you should set it explicitly in <tt>compile-widgetset.xml</tt>
with the following parameter for the Java process (currently included in the example build
script): <tt><jvmarg value="-Xss1024k"/></tt>.</p>
<p>As the OOPHM package is experimental, you should use it only for
debugging purposes during development. For production use, you should
compile your custom widget sets with the regular Vaadin package
for your platform.</p>
<h2><a name="known-problems">Important known problems in Vaadin @version@</a></h2>
<ul>
<li><a href="http://dev.itmill.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.</li>
<li><a href="http://dev.itmill.com/ticket/2299">#2299</a> The
Hosted Mode Browser does not work in Linux for debugging client-side
GWT code. You need to install the experimental OOPHM package instead
(see above) for development. For production, you should use the regular
package for Linux.</li>
<li>
<p><a href="http://dev.itmill.com/ticket/2891">#2891</a> As there is a bug in J2SE
5.0 that prevents setting the stack size for the main thread, widgetsets cannot be
compiled using the standard GWT compiler of GWT 1.6 and JDK 1.5.0 (see #2656 for
more details on the JDK bug). This bug primarily affects Windows users as other
operating systems have a larger default stack size.</p>
<p>Before that fix is available in a published GWT version, we provide a wrapper for
the GWT compiler that runs the compiler in a separate thread, thus using the
user-specified stack size settings also on JDK 1.5.0. Use
<tt>com.itmill.toolkit.launcher.WidgetsetCompiler</tt> instead of
<tt>com.google.gwt.dev.Compiler</tt>. You need the wrapper if you use a build script
to compile custom widget sets; the Eclipse plugin uses the wrapper
automatically. You can also avoid the problem by using JDK 1.6.</p>
</li>
</ul>
<p>For other known problems, see open tickets at developer site <a
href="http://dev.itmill.com/">dev.itmill.com</a>.</p>
<h2>Requirements</h2>
<p>Vaadin is available for the following operating systems:</p>
<ul>
<li>Windows (see the Zip installation notice above)</li>
<li>Linux</li>
<li>Mac OS X Tiger (mac) or Leopard (leopard)</li>
<li>Other UNIX operating systems, such as Sun Solaris, using the installation package
for Linux.</li>
</ul>
<p>Vaadin supports Java Servlet API 2.3 and later versions and should work with
any Java application server that conforms to the standard. It supports the following
application servers:</p>
<ul>
<li>Apache Tomcat, version 4.1 or later</li>
<li>BEA WebLogic® Server, version 9.2 or later</li>
<li>IBM WebSphere® Application Server, version 6.1 or later</li>
<li>JBoss Application Server, version 3.2.8 or later</li>
<li>Jetty, version 5 or later</li>
<li>Glassfish, version 2 or later</li>
</ul>
<p>Vaadin supports the following browsers for using the applications made with
it:</p>
<ul>
<li>Mozilla Firefox release 3</li>
<li>Internet Explorer releases 6, 7, and 8</li>
<li>Safari 3</li>
<li>Opera 9.6</li>
</ul>
<p>The support for browsers follows the support by GWT. The browsers are supported on both
Windows and Mac, if available. Firefox is supported also on Linux (Opera 10a1 works also
on Linux though also suffers from <a
href="http://dev.itmill.com/ticket/2652">#2652</a>). There may be differences between the
exact versions of the supported browsers that may cause incompatibility with applications
made with Vaadin.</p>
<p>The following browsers are not supported but have been found to
work to a large degree:</p>
<ul>
<li>Safari 2, and 4 beta</li>
<li>Firefox 2</li>
<li>Google Chrome 1.0.x (available only for Windows)</li>
<li>iPhone (firmware 2.2)</li>
<li>Midori (0.1.2)</li>
<li>Epiphany (2.22.3), Galeon, and other Gecko-based browsers. Also WebKit-based Epiphany (2.22.3) works.</li>
<li>Konqueror 4.2 (3.5.x does not work)</li>
<li>Nokia Internet Tablet N800 and N810 (ITOS 2008, Opera-based browser).</li>
</ul>
<p>The reported versions are those that have been tested, though other versions may work
as well.</p>
<p>Nokia E-series phones, such as E90, have been known to work with older versions, but
not with Vaadin 6. Links, Lynx, and other text-based browsers do not
work.</p>
