          <p>
	    The wx application now compiles and is usable with the
	    unstable development branch of wxWidgets-2.9. Some
	    functions are currently not available in wxWidgets-2.9
	    and their erlang counterparts are marked as deprecated.
	    They will generate an error if called when linked against
	    wxWidgets-2.9 libraries. This means that wx can now be
	    built on 64bit MacOsX, but keep in mind that
	    wxWidgets-2.9 is still a development branch and needs (a
	    lot) more work before it becomes stable.</p>

            <p>wxHtmlWindow class implemented.</p> <p>All exceptions
            from callbacks are now catched and written to the
            log.</p> <p>Some defines where wrong in 'wx.hrl'.</p>
            <p><c>wx:batch/1</c> and friends could hang forever if
            for instance a breakpoint was set inside the fun. That
            caused all wx applications to hang.</p> <p>Added missing
            wxAuiPaneInfo constructor and destructor.</p> <p>Added
            wxAuiNotebookEvent and wxAuiManagerEvent.</p> <p>Calling
            non supported wxWidgets functions hanged instead of
            crashed.</p> <p>Update OpenGL to version 3.1 and added
            some of the missing glu functions.</p> <p>Fixed
            wxRadioBox which inherited the wrong class, thanks Atilla
            Erdodi.</p>
