text = "A new adaptive time stepping (ATS) capability was added to the Advection (ADV) Package of the Groundwater Transport (GWT) Model. A new input option, called ``ATS_PERCEL'', specifies the fractional cell distance that a particle of water can travel within one time step. When ``ATS_PERCEL'' is specified by the user, and the ATS utility is activated in the TDIS Package, the ADV Package will calculate the largest time step that will meet this fractional cell distance constraint, and will submit this time step to the ATS utility. This option may improve time stepping for solute transport models and for variable-density flow and transport models by allowing step lengths to be calculated as a function of the flow system rather than being specified as input by the user."

The ``PACKAGEDATA'' block was removed from the EST package input. In its place, the heat capacity of water, the specified density of water, and the latent heat of vaporization are instead given default values that can be overridden by specifying alternative values in the ``OPTIONS'' block. Additionally, the following variable names in the EST package input have been updated as follows: ``rhow'' changed to ``DENSITY_WATER''; ``rhos'' changed to ``DENSITY_SOLID''; ``cpw'' changed to ``HEAT_CAPACITY_WATER''; and ``cps'' changed to ``HEAT_CAPACITY_SOLID''."

This option is relevant only when the Newton formulation is used, in which case dry cells remain active; otherwise, dry cells are inactive and particles will terminate.
