The roadmap is made up of changes or features I would like to make for upcoming versions and is not set in stone and could change at any time. While I'll do my best to stick to what's below, higher priority items sometimes come up. The roadmap could also change based on community feedback...there's no point spending time on features nobody wants or will use.
Mainly patch release for bug fixes
Add logging
This will be iterative so plan to improve a bit with each release
AI avoidance feature
Mainly patch release for bug fixes
Move pathfinding to background threads
Waypoint system
Allow providing a collection of points for the pawn to reach on its way to its final goal
Improved performance
Improved surface detection
Flying navigation
Localized/Relative navigation generation
This will allow anchoring navigation to a moving actor in some way
Think moving platforms/ships/etc...
