- Retained standard single-step undo and redo functionality via menu item.
- Enhanced Counter component:
- Counter state can now be displayed in "State" tab alongside registers.
- Counter state can now drive "Assembly viewer" address.
- Corrected appearance of OR gates in TikZ/SVG image exports.
- Corrected font choice for default fonts in SVG image exports.
- Reduced filesize of TikZ/SVG image exports.

- 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.

- 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 Behavior attribute to Pull Down.
- Updated Pin documentation.
- Subcircuits with clock input(s) are now drawn with a clock symbol.
- Added TTL 74194: 4-bit bidirectional universal shift register.
- Improved the English, French, and German localization. Smaller fixes were done to the other languages as well.

- Updated Java requirement to Java 21.
- Added an autosave feature along with preferences for it.
- Added a new preference to allow the user to choose the action keys for many functions.
- Changed RAM default output from error to undefined [#1747]
- Added support for scanning 7-segment display on FPGA-boards
- Added first support for the openFpga toolchain for the ecp5 famely
Note that this is experimental for the moment, so use it at your own risk.
- Improved Chinese localization
- Changed language code from cn to zh.
- Chinese users (also including those who use other forks of Logisim
that are using cn language code) will be required to manually modify language settings.
