If you are upgrading from a previous prior to 0.40 :-
I do not advise you just drop this version over the top of any version prior to 0.40.
Instead, copy the profiles file from inside the config dir into the same place in this version.
Profiles will automatically be updated to the current version format if its from a relatively recent version. If you are upgrading from a rather old copy then you might be well advised to start afresh with profiles.
Changes in this version from 0.40 :
20th Feb 98
