Since this is an external project, you are at the mercy of the developers to provide updates (or publish the source code so you can write updates yourself).
As far as I can tell from the download page, the last update was in 2017 and "contains many bug fixes and compatibility modifications to support newer versions of MATLAB."
Unless the author(s) happen to watch this forum, you are in the same position as anyone else to fix compatibility issues. Well-written code tends to keep working, but once mex files are involved, you may have a lot of issues or be in luck.
