This is the last change to that part:
:group GROUP Custom group name to use in all generated `defcustom' forms.
Defaults to MODE without the possible trailing \"-mode\".
- (This default may not be a valid customization group defined
- with `defgroup'. Make sure it is.)
+ Don't use this default group name unless you have written a
+ `defgroup' to define that group properly.
The previous version may have been clearer? I think what it's trying to
say is that if you have a :group, then you should make sure to add a
defgroup to that symbol.

Presumably this is because there are things in a defgroup that should be
there, but aren't if you don't use a defgroup? I.e., :link and a name
for the group.
