Qucs-S 2.0.0

Important notes

The simulator switching system was redesigned since this release. It allows now to switch simulation kernel without restart of the application. But it is required to reconfigure simulator paths even if it was configured for the previous installation. A Simulator settings dialog window will appear on the first application start after the update. Please check the simulator settings and correct if necessary to continue work.
