For Highcharts Stock, the ordering of series and axes in the chart.series, chart.xAxis, chart.yAxis and chart.axes arrays were changed. Previously the navigator series and axes were last of the initial items, and when adding items they were appended. From now on, the internal navigator series and axes are always last, so the index of items now corresponds to that of the current options.
