	<h2>Bowler Scala Web Framework version 0.4 Released!</h2>
	<i>May 23rd 2011</i><br/>
	Version 0.4 of Bowler, a RESTful, multi-channel ready web framework in Scala has been released. For details on how to get the code, get started etc, please check the <a href="/">homepage</a> or <a href="/manual.html">the manual</a>.<br/><br/>
	This is the fourth release and has focused on Scala 2.9 compatibility, more uniform API's around Scuery & Scalate templating, an entirely re-vamped and simplified Layout API, more concise route-definitions and making parts of the API more idiomatic in terms of Scala.<br/>
	The <a href="https://github.com/bowler-framework/Bowler/tree/master/examples">Bowler Example application</a> in our GitHub repository showcases a lot of the new features.<br/>
	A list of changes and new features below:


	<h3>Change highlights for version 0.4</h3>
	Perhaps the most notable change for 0.4 is that we now allow route-definition by function-name-convention:
	<script src="https://gist.github.com/950432.js?file=POSORouting.scala"></script>
	..the old Scalatra-inherited route-definition will still remain, and the above example actually builds on top of it, but the function-name-convention style may be appropriate for Bowler users who are prepared to trade some type-safety for increased conciseness of their code.

	<h4>Feature Highlights</h4>
	<ul>
		<li>Cross-built against both Scala 2.8.1 AND Scala 2.9.0 (Scala 2.9 build relies on some SNAPSHOT builds of other projects, which should be mentioned)</li>
		<li>"Function name convention based routing" available, setting HTTP routes by function name, like: <i>def "`GET /myresource/:id`(widget: Widget)"</i> (see example above)</li>
		<li>Layouts <a href="/manual.html#layouts">entirely revamped</a> and now <a href="/manual.html#scopedlayouts">scoped</a> (set globally, controller level, route level or view level)</li>
		<li>Scuery now a <a href="/manual.html#components">first class citizen seamlessly integrated into the API</a>:
			<ul>
				<li>Usable as view</li>
				<li>Usable as layout</li>
			</ul>

		</li>
		<li>Better support for Option at top-level of hierarchy for JSON output</li>
		<li>Support for BigDecimal in JSON output by default</li>
		<li>Better support for user-defined Serializer for JSON input/output</li>
		<li>New optional <a href="/api/index.html#org.bowlerframework.view.StrictRenderStrategy">StrictRenderStrategy</a> which follows HTTP more strictly (no workarounds for IE and Chrome browsers)</li>
	</ul>


	<h4>API changes</h4>
	<ul>
		<li>Changed Request interface to use Option where nulls could previously be returned</li>
		<li>Layouts API entirely changed</li>
		<li>Layout- and Suffix selectors removed, generalised Scala extractors package added</li>
		<li>Re-packaged org.bowlerframework.view.squery to org.bowlerframework.view.scuery</li>
	</ul>

	<h4>Bugs fixed</h4>
	<ul>
		<li>fixed content-type emitted for application/json to be correct</li>
	</ul>
