 - ``ConfigureStopTime`` now supports specifying the stop condition as ``<=`` (default, prior behavior) or ``>=`` (new).
   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.
+- Configured the :ref:`prescribedMotionStateEffector` module for attachment of other state effectors to it
+  rather than the spacecraft hub.
+- Configured the :ref:`spinningBodyOneDOFStateEffector`, :ref:`spinningBodyTwoDOFStateEffector`, and
+  :ref:`linearTranslationOneDOFStateEffector` modules for optional attachment to the prescribed motion state effector.
+- Added two example branching scenarios to illustrate the prescribed motion branching capability. See
+  :ref:`scenarioPrescribedMotoinWithTranslationBranching` and :ref:`scenarioPrescribedMotoinWithRotationBranching`.
