- This upgrade requires OS X 10.11 (El Capitan) or better.
- Rewrote the full-screen feature; it now works for individual windows, using the familiar green button in the window title.
- The main window can now be resized freely, and is not limited anymore to the small / medium / large sizes.
- Fixed an issue that caused the application to incidentally ignore ROM files in the application folder.
- Closing a virtual machine while the Inspector window is open no longer results in a crash.
- Improved the screen refresh performance; this fixes an issue where the Apple II screen sometimes briefly showed gray areas.
