The new option is useful when the user wants to ensure that the simulation runs for at least the specified time,
instead of at most the specified time.
- Fixed documentation quote typos that caused documentation build errors with doxygen version 1.15 and newer.
- Support for stochastic dynamics (dynamics driven by Stochastic Differential Equations). Added two stochastic integrators:
:ref:`svStochIntegratorW2Ito1` and :ref:`svStochIntegratorW2Ito2`. These are 2-weak-order stochastic integrators.
- Added :ref:`scenarioStochasticDrag`, which illustrates how to use a state driven by stochastic dynamics to
model randomly evolving atmospheric density (and thus drag force).
