Scott,

We are working hard to get J2Commerce V5 ready by the end of the year. We are refactoring the codebase to be native Joomla 5/6 while also making it as seamless as possible for current J2Commerce users (including all of the supporting extensions) so the trade-off is that current J2Commerce users will have to wait a little bit longer before they can migrate to Joomla 6, but in return, will have more features and functionality on a code base that will make it easier for us and other develoeprs to maintain and build on.

Hang tight a little bit longer, but rest assured knowing we are working hard to make sure we release this as quickly as possible without mucking things up  :)

Adam
