ThinkGeo has updated all of the products in their Map Suite line this month to version 5.0 and has included a variety of new features, many of which are aimed at making their GIS software suite compatible with a wider range of data types, including TAB and projection metadata (PRJ). There's also built-in support for Bing Maps in every product, and the Map Suite Web Edition product gets upgraded to OpenLayers 2.10 and Google Maps API version 3. The full release details have been posted on ThinkGeo's developer blog.
The company has also invited the community to submit and vote on suggestions for enhancements to future releases of Map Suite, for which they have set up a site called the ThinkGeo Enhancement Tracker. You don't have to log in or anything, so it's easy to head over there and vote on stuff you think Map Suite needs.
