Where can I find the changelog of the newest updates of both plugins for WordPress Woocommerce? I would like to know if the update included the possibility to create a dropdown menu for MSPC instead of redio buttons.. 

And if not, how can I figure out that in the future this feature will be added in the plugin?

Thank you for your reply.

You'd only know by taking a look every now and then. But as the only feature request for this was marked by the developer as not taken I don't think it will come  - that is unless you make a new one with more compelling arguments.
