- Fixed synchronization and efficiency issues in wires and propagation.
- Fixed synchronization and efficiency issues in propagation listeners.
- Limited redraws to about 20 frames per second to reduce overhead.
- Allows users to choose a simulation queue, which changes the efficiency of the simulator depending on circuit design.
- Simplified Type and Behavior attributes of Pins.
- This change will break circuits with input pins that need to pull floating values to 0 but do not
have the Pull Down setting. To fix it, set the Behavior attribute to Pull Down.
