Hi Frederico,
the problem with maintaining the datastore is keeping up with compiler changes. I do have some deployed applications (using SBCL), and I plan to use it (with CCL) in the nearer future. Whenever I'm working on something new or do a major update on my deployed applications, the store will receive some love. I cannot make any predictions or promises if and how this will happen, but I am not considering the project to be closed.
Best, Hans
