With ticket [#158] we plan to start using SP18 development environment and compiler version.
The current library progress will be saved in a way that can be accessed in V3.5 SP16 Patch 1 or newer. And then future development will be done in SP18.
The new compiler version brings some enhancements which will make the library faster and use less application memory such as native UTF8 support, and contains some more features like VAR_GENERIC which would be useful for datasets. Also it has the latest bug fixes. We are also interested in exploring the HTML5 controls feature for the host, when that is released.
