When Concrete CMS made the big jump from Version 5.6 to 7.0, they basically rebuilt the whole system from scratch. This was great for adding new features, but it meant all the existing add-ons (including ours) stopped working. It's the first time this has happened, and the Concrete CMS team isn't planning to do it again anytime soon.
The downside? We had to rebuild all our add-ons and themes from the ground up. That's a lot of work, and we couldn't do it for everything right away. So, we started with our most popular add-ons (like Mega Menu) and have been working our way through the list. We're also taking this opportunity to create some new, cutting-edge add-ons (like Find & Replace).
