is there any coming update soon to cs-cart or next year
This is a user-to-user forum. None of us know any more about that than you do. Sometimes CS-Cart staff will come on here and comment, but even then, they may not wish to reveal future plans. Is there a particular feature you’re hoping for?
Plans are in place to release version 4.21.1 this summer. However, this is not set in stone and could change if the planned core features are not ready in time.
