Hi,
The current version of CleanMart well supports VM3.2.1 + Joomla3.6.5, no bug has been reported since the latest release. Thus; we don't see any reason to release a new version; 'cause you know what they say: "If it is not broken, don't fix it" :) But if you experience anything wrong with the latest CleanMart along with latest VM3.2.1+Joomla3.6.5; please do let us about it. We are happy to patch and release a new version.
If you meant to ask adding some "new features" to CleanMart with that new release; then in the near feature we don't have any plan about that. But this doesn't change the fact that we might have.. But, to be honest with you; we are more focus on MaterilaMart these days (
www.flexiblewebdesign.com/Virtuemart-Templates/MaterialMart). It is newest Virtuemart Template we have as of now. If there is a "new feature" (i.e: wishlist, compare, filter etc..) MaterialMart will have it first; the others (CleanMart, SportMArt, Asymmetric etc..) will come later
Regards.
