Great to see you have released the new 4.0 version. You also have a new branding and its looks nice.
Seeing only APIs of old version in the My Account > API Downloads. For quick reference, we have Lifetime license for upto 10 sites of your products (almost all extensions with some exceptions). How do we get started with the new version?
P.s.: We were unable to use your product in production as there were some logical errors that were promised to be fixed when the new version was available. From earlier this year – https://multivendorx.com/support-forum/topic/unable-to-limit-vendor-from-publishing-product-without-approval/
