This major release introduces many new features and bug fixes.
The new features introduced in version 7.0 are:
the complete DSST semi-analytical propagator with short-periodics terms (only mean elements were available in previous version),
extension to second order derivatives for many models (Cartesian coordinates, angular coordinates, attitude modes, …),
bilinear interpolator in Saastamoinen model,
attitude overriding during impulsive maneuvers,
general relativity force model,
geographic zone detector,
Several bugs have been fixed. One noteworthy fix concerns an inconsistency in Eckstein-Hechler propagator velocity, which leads to a change of the generated orbit type.
Version 7.0 depends on Apache Commons Math 3.4.1.News summary
