In the next major release, we will target Joomla 4 support definitely. We haven't finalized our other goals of the release but want to focus on some optimizations to reduce load times, revamp our Channels functionality to be a more complete solution for auto-posting, including a better mechanism for scheduling posts. Alex and I are still discussing what we want to include.
