phpGoogleMaps ver 0.6 – release notes

+ var $this->GTerrainControl[true/false] property added. It enables/disables the terrain map type button.
+ var $this->GHierarchical[true/false] property added. It enables/disables (default false) the new type of map type button menu because the Hybrid button was removed, and was replaced with a drop-down menu under the Satellite button with a Show Labels checkbox. This new UI reflects the fact that the hybrid layer really just consists of satellite tiles combined with a transparent tile layer of information from the standard map tiles.
When GHierarchical is set to true, set GMapTypeControl propery to false => it enables the new type of map type button menu.
When GHierarchical is set to false, set GMapTypeControl propery to true => it enables the old type of map type button menu.
