- Added undo/redo functions.
- New wire drawing mode: If a wire is added it is rectangular by default.
In rectangular mode "F" flips the wire and pressing "D" switches to diagonal mode.
- Added inverted inputs for basic gates and flip-flops.
- Added a locked mode, which avoids the unwanted modification of the circuit.
- Better support for high dpi screens.
- Added DIL packages to allow more "physical" circuits. See examples/74xx.
Up to now only a view 74xx circuits are available.
- Added a pin number attribute to inputs and outputs.
- Add some functions to make it easier to create 74xx circuits.
- Lots of small usability improvements.
- Added a list of keyboard shortcuts to the documentation.
