In version.c, HUGSROOT is defined as:

This means that the settings from one installation of Hugs do not persist when the user installs a new version. This is unfortunate as it means that when people upgrade, they will loose all their preferences such as text editor, along with their hugs options as well.
Is there a good reason for this behaviour? Are options between different versions really totally incompatible?
Beats me. This has been there since the dawn of time (Dec 1996), so I don't know if anyone knows. Options don't change very often, and we use warnings for a while for the ones we remove, so that shouldn't be a problem. It's up to you.
