Added demonstration of async data loading in Highstock.
Added support for rotation of text when useHTML = true in modern browsers. #916.
Changed the default line width for area range charts to 1 to avoid the area disappearing altogether in ranges where the min and max are equal. #1213.
Reorganized VMLRenderer to move groups (divs) out of the viewport instead of toggling CSS visibility. This provides a faster and more compact fix for #61 and #586.
Rendering performance improvement due to better caching of bounding box for texts, leading to less DOM traffic.
Worked on zoomType for stock charts, allowing the reset button to work more intuitively (#979).
