I found that. Seems it mainly addresses caching and database performance, adds some admin and moderation commands. I'm not sure if it addresses any of the shortcomings I have.
My main question is: Which one is going to be maintained in the years to come and have the latest features implemented? And secondly: Why a fork? Why don't they contribute their fixes upstream to Conduit?
Oh well, seems both reasonable. Maybe I should switch before the projects diverge too much. Conduwuit seems pretty active. Hope it stays that way.
Do you happen to have a link where I can read the backstory myself? Thanks for the info anyways. Seems to be a good call.
