  occurring in the output. (#3867)
- Added `Output`s to `ExpressionBasedCoordinateForce`, `ExpressionBasedPointToPointForce`, and `ExpressionBasedBushingForce` for accessing force values. (#3872)
- Changed all `printDescription()` and `printDescriptionImpl()` methods to log at level info instead of cout. (#3888)
