Hi,
Yes you are right. But after we updated the CleanMart (which is the advanced version of PureMart) for the latest VM3.0.16 and Joomla3.5.1 . We decided to postpone the PureMart update.
In the near future, we don't have any plan for releasing update(s) for PureMart.
You should better consider switching to CleanMart. It is a way more advanced theme comparing to PureMart. CleanMart and PureMart works exactly the same. They both integrates to any Joomla Template and styles only Virtuemart related pages. CleanMart offers multiple versions for both Category and Product Details page, comes with a better ZoomEffect plugin, has a unique shopping cart page, and better shopping cart module etc..
