       The <b>Error Log</b> view has been moved from the PDE project to the Platform project.
       ISVs should examine their build infrastructure for inclusion of the <strong>org.eclipse.ui.views.log</strong>
       plug-in. The inclusion in your own features and/or products may be redundant because this
       view now ships with the base platform. See <a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=50517">bug 50517</a> for details.

      <td class="content">
       UI model elements can be marked as transient, which means they do not get persisted when the
       application is closed. This allows to create views and other UI elements dynamically from code
       without the need to clean them up properly before the workbench is closed. It also allows to contribute static model fragments which are not persisted and therefore removed once
       the plug-in gets uninstalled.
       <p>To mark an element as transient simply call
       <code>uiElement.getPersistedState().put(IWorkbench.PERSIST_STATE, "false");</code></p>

       New widget factories have been created for some SWT widgets. They follow the same approach as <code>GridLayoutFactory</code> and <code>GridDataFactory</code> i.e. a fluent, re-usable API.
