Build 4.0.0.45 makes deployment of xlsgen simpler by not shipping Sparklines.ocx anymore.

Sparklines.ocx included 4 visual controls, namely the vumeter, sparklines, google charts and google geomaps. As depicted :


The 4 visual controls are now native in xlsgen

Those controls are still available in this build and if you were using them, there is no breaking change. What is changed is the fact that these are native built-in controls in xlsgen.dll, so there is no external exposure in sparklines.ocx anymore (there was a /visualcomponents folder in the install).

The reason those controls are now built-in is that not only the hassles of deploying the additional file is now gone, but more importantly the visual controls were implementing ActiveX interfaces and as such could prove hard to enable in a number of server-side environments depending on your corporate policy.

Thanks to the controls being now built-in, the deployment problems related to it are no longer a subject of discussion.
