The new version has a template for the subcategory. Simply copy the subcategory.html from the distribution, edit it if you want, and then put it in your templates directory.
The subcategory.html seems to be the first step in moving the last vestage of non-template-based html generation into the template based arena.
I was able to modify the new routine to do my front page in a few minutes, and it will be much easier to make changes now, since the template uses <%tags%> rather than $variables.
