  • Allow resetting wind-up.
  • Improved shiftedBy in (Field)StateCovariance.
  • Override getPosition in (Field)ShiftingPVCoordinatesProvider.
  • Remove some calls to deprecated methods.
  • Revamped release process, using fully automated scripts and continuous integration.
  • Fix equals in FieldAbsoluteDate.
  • Add durationFrom with TimeStamped in FieldTimeStamped.
  • Add Jacobian matrix to Lambert solver.

  • Add STM to Gradient state conversion.
  • Add Gradient state utils.
  • Add reset state saved in (Field)EventsLogger.
  • Restored JB2006 model.
  • Add FieldGroundAtNightDetector.
  • Add TimeIntervalsManeuverTrigger.
