2.10 is on the way
-(obviously) UE 4.23 support
-visualization for the barrel component (mismatched barrels were frequent cause of problems in multiplayer games, hopefully option to make them visible will make it easier for you to identify those)
-network trajectory update exposed to blueprint - allowing you to add ricochet sounds etc. without any extra network traffic (experimental).
-fixed occasional glitch where bullets stuck in obstacles remained active
-some internal cleanup
Update is currently being processed, should be up in a few days.
