What's new in 4.0.0

- v4.0.0 (2025-09-07) - Updated VHDL and created Verilog generator for RAM component with byte-enables - Added VHDL and Verilog for the RAM component with line-enables - fixed clasic appearance shift-register bug - Added automatic custom Logisim library loading at startup. - Created unit tests for loading custom Logisim libraries at startup. - Updated documentation for the automatic loading of custom Logisim libraries. - New take on project export/import. A zip-file is generated which can include a user provided "README.md". - Added Telnet component. - Added Metal graphics acceleration option. - Added option to hide/show toolbar - Improved drawing appearance. - Fixed TTY appearance bug while changing various zoom levels. - Corrected appearance of NOT gates in TikZ/SVG image export. - Corrected disjoint corners in arrow-style Pins. - Improved output of rectangles with rounded corners in TikZ image export. - Fixed Undo/Redo issues. - Fixed Power-on-Reset propagation issue. - Redesigned simulation engine to fix synchronization issues and increase speed. - 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 Beh...
