The first public preview release of Synergy Advance is now on the servers. You can download it here. Please see the road map and the known issues. If you discover any bugs please file a report (see the bug reporting guidelines here and the instructions for beta testers here). You can purchase a license here or support further development by sponsoring or making a donation.
This release is the core application. I was hoping to ship more modules with the first preview, but I ran into a few Cocoa problems in the second half of this month that ending up eating several days each when I had planned to spend only a single day on each item. So I’ll be following this release up with another preview soon.
