I'm happy to announce the release of Ultra Fractal 6.04. This free update for existing version 6 users fixes several issues on Windows and Mac, especially when running on macOS 11 (Big Sur). You can download it here:
Just let me know if you experience any problems with the update.
Note: because these downloads are new, Windows 10 might flag them as an uncommon download. In this case, click the "More info" link in the dialog that appears when trying to install. Verify that the publisher is Phreakware (my company) and click "Run anyway" to install.
