The 3.4.1 update of the MeVisLab SDK software fixes some bugs and offers some small new features and improvements.
We also tested the macOS version against the just-released Big Sur version of macOS (on Intel processors) and found no obvious problems.
See the MeVisLab Release Notes for details on the fixes and improvements. The MeVisLab 3.4.1 Bugfix Release is available for download on all supported platforms at the MeVisLab Download page.
