<section><title>ET 1.4</title>

    <section><title>Improvements and New Features</title>
      <list>
        <item>
          <p>Thanks to Olle Mattsson the GUI parts are rewritten to
          use <c>wxWidgets</c>. For the time being it is still
          possible to use the old <c>GS</c> based version of the tool,
          but it is deprecated. The <c>wxWidgets</c> based version is
          started by default.</p>

          <p>A print function has been added, in order to enable
          printing of sequence charts.</p>

	  <p>A new tutorial has been added to the documentation. It is
	  based on <c>Jayson Vantuyl's</c> article
	  <c>http://souja.net/2009/04/making-sense-of-erlangs-event-tracer.html</c>.</p>

	  <p>The functions <c>et:trace_me/4</c> and
	  <c>et:trace_me/5</c> has been introduced in order to replace
	  the deprecated functions <c>et:report_event/4</c> and
	  <c>et:report_event/5</c>. Hopefully the new names makes it a
	  little more obvious what the intended usage of the functions
	  are.</p>

	  <p>The <c>max_events</c> configuration parameter to
	  <c>et_viewer</c> is not used any more. Now the event cache
	  in the <c>Viewer</c> only contains those events that
	  actually are displayed in the GUI.</p>

        <item>
          <p>
            The documentation is now built with open source tools
            (xsltproc and fop) that exists on most platforms. One
            visible change is that the HTML frames are removed.</p>
