OpenLayers 2.0 Release Notes

 * Deprecated Methods which were removed: 

 For details, see r1228

 * OpenLayers.Map
   * removed: getFullExtent() -- use  getMaxExtent() instead
   * removed: zoomToFullExtent() -- use  zoomToMaxExtent() instead
 * OpenLayers.Layer.Grid
   * removed: setTileSize() -- user should instead pass a 'tileSize' property 
              as one of the options when initializing the Grid Layer. ex: 
        
        var url = "http://octo.metacarta.com/cgi-bin/mapserv";
        var options = {tileSize: new OpenLayers.Size(500,50)};
        var map = new OpenLayers.Map('map', options);
        layer = new OpenLayers.Layer.WMS(name, url, params);

 * MouseWheel
  * It is now possible to zoom in/out with the mouse wheel instead of clicks.

    now start loading tiles from the center of the map.

 * Tile Re-Use
  * In order to lower memory constraints and reduce element creation times, 
    OpenLayers now creates a single set of images/tiles and reuses them as 
    you scroll around the map.

 * New Layer Support

  * Virtual Earth
  * GeoRSS (RSS 1.0 and 2.0 in FF, IE, RSS 2.0 in Safari)
  * KaMap
