- (Significant) Enhancement: Selection of labels now considers label area, not just label origin point
- Bugfix: Making 'R', 'L' and 'C' parameters for the respective Spice elements beside "value"
- Enhancement: Zoom In/Out menu functions now use the current mouse position for the zoom fixpoint (important when binding them to a key)
- Bugfix: More consistent behavior of RBA/pya: enum classes are properly made available (was for example RBA::Qt::Qt_Keys instead of RBA::Qt_Keys and pya.Qt.Keys was no fully initialized type object)
- Bugfix: Netlist reader: anonymous circuits (without definition) will not fail because of unknown parameters

- Enhancement: Somewhat better grid snapping in partial edit mode
