XF 2.1 Tutorial in differences in XF 1.5 and 2.1

[trman]

I just upgraded to 2.1. I notice that in the Admin CP the templates do not list the templates that are included in them at the top with tabs like 1.5 did. Is there a tutorial that explains the differences in 1.5 and 2.1 as far as templates, including templates in other templates and so forth?

Or it if is in the manual please direct me to the proper page.
