Well, we just recently released Geocortex Essentials 1.5 and we’re gearing up to release Geocortex Essentials 1.5.1 on January 7th. Despite its close succession to the release of 1.5, 1.5.1 includes a lot of stuff; both features and bug fixes.
A few of the new features are old friends - modified versions of features implemented in Geocortex IMF like user-defined Extent Bookmarks, Zoom to Layer Scale, configurable scales on Print Templates and Map Grid; however there are a couple of "flashy" features new to this release that are pretty exciting. Swipe Layer and Layer Transparency, to name a couple (screenshots below).
