Bing Maps V8 already added features such as streetside imagery, business intelligence tools and autosuggest back in June. Today's update includes further feature additions as well as multiple bug fixes.
Here is a list of some of the major changes in the build:
Spatial Math Geometry: The Spatial Math module has had a massive addition consisting of 24 spatial geometry calculations, bringing the total number of calculations available in the spatial math module to 47. Some of these calculations include: binary operations of shapes (intersection, difference, union), convex and concave hulls, Voronoi diagrams, shape validation and much more.
Draggable Pushpins: Easily move drag pushpins around on the map by setting the draggable pushpin option to true.
Custom Overlays: Custom overlays allow you to create your own custom rendering layers with the map control…With this feature we have added a supported way to create custom rendering layers so that developers can easily create and experiment with new custom data visualizations.
Clickable Pushpin Area: V8 now lets you specify that a rounded click area should be used instead. Early testing has found that this drastically reduces false clicks on pushpins and thus creates a much better user experience.
GeoJSON and Query API Shape Styling: With this update, any Pushpin, Polyline or Polygon option can be specified for individual shapes through the shapes GeoJSON properties or as a data source column in the Bing Spatial Data Services.
Mercator Map Type: Bing Maps provides road and aerial maps which are great in most cases, but sometimes you may want to hide these all together. Perhaps you have your own custom tile layer that you want to display instead, or perhaps you simply want to view your data on its own without a map background. You can easily do this now by setting the map type id of the map to mercator.
Bug Fixes: Since the initial release of V8 many developers have been proactive in reporting bugs and testing the fixes in the experimental branch. With this release there are over 60 bug fixes.”
As you can see the update adds a whole host of new tweaks and features. There are so many that they aren't all listed here. To see the full list, you can read the What's New documentation.
