Diamond firmware 0.5.0: FET output finally supported

Hi,

the 0.5.0 release does not bring any new features in respect to the user interface. But it finally provides official support for FET control (forward and reverse phase angle control, each for active-high and active-low ("inverted") output stages).
A simple schematic for FET control can be found in the Diamond hardware package since release 0.9.6-1.
This release brings many stability and angle range optimisations in the internal phase angle controlling system.

Have fun!
Mark
