            SUMMARY OF CHANGES IN RIVERWARE PATCH RELEASE 7.4.2
           -----------------------------------------------------
                        Released February 7, 2019
           -----------------------------------------------------


Object Dispatching
----------------------
In rare circumstances, object redispatching did not work correctly in
Rulebased Simulation when there were Input flags (I or Z) on the governing
slots. Now the algorithm to determine the method to redispatch always
chooses the previous method if no other method can be found, guaranteeing
that the object will redispatch a method. This change could cause some
objects to redispatch when previously they did not, leading to different
behavior. Other than the case in the bug model, 6227, our testing did not
find any such models.

Windows Task Bar, Per-process Button Grouping
----------------------
By default, Windows creates a single taskbar button for each application
that is running. When an application has multiple top-level windows open,
the taskbar buttons for these windows are combined into a single "stacked"
button. This behavior was changed so that now Windows displays a distinct
taskbar button for each RiverWare process. In addition, the RiverWare icon
used for that button is the same RiverWare icon displayed in the title bar
of that process's windows. This icon can be changed in RiverWare from the
Utilities, then Windows, and then Windows Icon menu.

Model Report Settings
----------------------
Two new report item setting were added:
• List Rules in Order of Execution: A new setting, "List Rules in Order of
Execution" was added to the RPL Set and RPL Group items. If "Yes", when the
output includes executable rules, they are listed in order of execution
(agenda order), instead of first to last. This setting is useful for
Rulebased Simulation and Initialization Rules Sets, which can be executed
in "...3,2,1" order.
• Show Execution Properties:  A new setting "Show Execution Properties" was
added to the RPL Set, RPL Group, and RPL Rule/Goal items. If "Yes", the
output will include additional information related to execution, as
appropriate. Specifically, this setting controls whether the following
properties are shown: Index, Flag, Priority, and On (Yes/No). These
properties correspond to columns of the RPL set editor, as applicable to
the type of set.

Bugs
----------------------
The following bugs were addressed:
6188: Create similar plot pages for different objects did not work for Agg
      Series Slots.
6214: The Add Item feature in the Model Report output tool was not
      consistent with other selection features.
6219: Initialization Rules Set name did not persist when exported to a
      separate file.
6221: Table Series Slot row labels were not updating correctly when the
      date range changed.
6222: A Database DMI would not work correctly when a slot set it referenced
      was deleted.
6223: In a script, the Set Scalar/Series/Table Slot actions were not
      correctly setting datetimes to symbolic datetimes or RPL functions.
6227: In very rare circumstances, Object redispatching did not work
      correctly in all situations in RBS when there were Input flags, see
      above.
6231: On the Groundwater object, the Head Based Boundary Condition method
      was not solving correctly when solved at multiple priorities. Now,
      the method only sets the previous Elevation when it has a different
      value.
