 * Allow for the Vizard output path to be specified as a .bin file instead of just a directory.
 * Use Vizard 2.3.1 locations for visualization; results in significantly smaller output
   files.
+* Add an example script demonstrating target location uncertainty modeling with uncertainty growth over time: `Target Location Uncertainty <examples/target_location_uncertainty.ipynb>`_ example.
 * Allow for a simpler Earth model to be used in Vizard by setting ``use_simple_earth=True``
   in the Vizard settings dictionary. This is helpful for when visualizing may Earth-fixed
   targets.
