I have been using F2C for a long time now and have many content types and plugins. (Note I don't have a current subscription) I am preparing for migration to Joomla 4 and so far have a working site with most of the components I need - it has been a steep learning curve converting my extensions with little documentation available.
I am wondering when you expect the new version of F2C to be ready and would be happy to test a beta version for you. I would be your first customer for the new version
