Hi,
Thanks for your feedback. One of the main reasons we are a little more focused on 1,0,x is that current usage and download stats show that our members are still using the 1.0.x versions allot more than 1.5. That said however, we are working to get concurrent releases of all templates in the near future.
With Aurora however, it is a little more tricky, the component that handles the 80+ configurations of the template is not 1.5 ready. We had aimed to be done with it this week and put some late nights in to be ready today, but there just were not enough hours in the week

so it will have to be next week and we can finish off the 1.5 version.
I hope this clarifies things a little, all the best...
