New subscription model
We decided to stop giving away Explorer licenses for free. The major reason was that due to an increasing number of active users our effort to support these users also increased quite a bit. That created a non-sustainable situation especially in the context of rising costs due to inflation.
Instead of a free license we now offer low-cost subscriptions. We hope for your understanding considering that even with a limited feature-set compared to Sonargraph-Architect the Explorer license still offers a lot of value.
If you are currently using Sonargraph-Explorer your current license will remain valid until its expiration date. Then you would have to buy a subscription if you want to continue using the product.
