Well, there's the tradeoff.

With tags, you can precisely identify exactly what set of file versions
perfectly correspond with the project version in Stellation. With the
changelog, you can more easily look at what's going on.

Doing both is probably the best bet, but I still don't know how well
CVS is going to cope with lots and lots of tags.
