    • So-called energy cost functions (proportional to the integral of the control vector’s squared norm), with Hamitonian evaluation
    • Single shooting based on Newton algorithm for the case of fixed time, fixed Cartesian bounds
  • Attitude
    • Implementation of attitude provider with primary target and secondary constraint
  • Data parsing
    • Implementation of a parser for GRGM1200B-like gravity models
  • Noticeable bug fixes
    • Use proper body-fixed (ITRF) frame in DSST zonal (see Issue 1104)
    • A long standing bug on the Brouwer-Lyddane model has been fixed (see Issue 947)
  • Miscellaneous
    • Impulsive maneuvers can now be added to relevant PropagatorBuilder
    • PropagatorBuilder are now cloneable
