-Added low storage Runge--Kutta module, :ref:`LSRKStep <ARKODE.Usage.LSRKStep>`, to ARKODE. 
+Added a time-stepping module to ARKODE for low storage Runge--Kutta methods, 
+:ref:`LSRKStep <ARKODE.Usage.LSRKStep>`.  This currently supports five explicit low-storage 
+methods: the second-order Runge--Kutta--Chebyshev and Runge--Kutta--Legendre methods, 
+and the second- through fourth-order optimal strong stability preserving Runge--Kutta methods.  
+All methods include embeddings for temporal adaptivity.
