The roadmap is not published in detail during the pre-alpha -- the plan moves too often to be worth committing to in public yet. In broad terms, what is ahead:

   - flexible and triggered downtimes (only fixed-window downtimes exist today)
   - an Icinga 2 importer, alongside the existing Nagios one
   - a remote agent, for checks that need to run from outside the engine's
     own network reach
   - live dashboard updates, replacing the current 5-second poll with a
     push mechanism

See Status for what is shipped today, and Design decisions for the reasoning behind the architecture.
