MouseWheel

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

Spiral Gridding

  • Instead of loading from the top to bottom of the map, !Openlayers will 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

Scale Based Methods

  • It is now possible to set zooms based on the concept of scale. See documentation in the options for the Map constructor.
