+# Release Notes for Dymos 1.9.0
+
+September 07, 2023
+
+Dymos 1.9.0 changes the default timeseries behavior so that state rates,
+control rates, and t_phase are not included by default. These values tended
+to clutter the timeseries plots on more complex problems.
+
+A new `add_duration_balance` method is added to phases that allows the final time
+of a phase to be found with a solver without the need for an optimizer. This is useful
+for explicit shooting phases which are effectively just simulating out the dynamics
+until some target condition is achieved. An example of this behavior is available [in the docs](https://openmdao.github.io/dymos/examples/cannonball_implicit_duration/cannonball_implicit_duration.html?highlight=duration).
+
+Trajectory parameters are improved. Parameters can now have a mix of static and dynamic targets, which was not possible before.
+Also, trajectories will now use variable data obtained by introspection in the phases for
+setting properties of trajectory-level parameters.
+
+The behavior of some scipy.sparse routines was changed in 1.11 and caused incorrect derivatives.
+This has been addressed.
+
+Dymos had previously been calling `allgather` excessively under MPI which could
+cause performance issues during setup.
+
+Finally, Trajectory.simulate() should now work correctly under MPI so that results can 
+be checked with explicit integration when working under MPI.
+
