Do you mean a change in GRASS GIS source code or your system configuration
(e.g. updates)? How to decide between them is to configure the last version
of GRASS GIS which worked for you. If you can configure and compile from
scratch that old version but not the new one, you can try a version in
between these two, the go to beginning of this sentence (aka bisect). This
way you find the change in GRASS GIS. In case both the old and the new
version don't configure, the change is in your system.
