This file contains the changes that have been made to Arrow 8

*** Changes for Version Date 2020.03.30 ***

None: Initial Release



*** Changes for Version Date 2020.04.22 ***

>> Changes to computation logic that could impact results <<
1.   Fixed a problem displaying temperature Design Alerts in a graph.
2.   Fixed a problem displaying temperature values in graphs.
3.   An incorrect fluid temperature was being used to calculate fluid properties for
     internal convection coefficient correlations. The error is proportional to the
     thermal difference from bulk fluid temperature to ambient temperature, and may be
     exacerbated when the flow is in or near the transitional Reynolds Number range.
     Models with moderate heat transfer will see minor impact. This has been corrected.
4.   When an outflowing Assigned Pressure Junction was defined with a K Factor, there
     was the possibility for erroneous results at high flows. The reported flow may
     have been higher than is physically possible, due to sonic choking after the loss
     not being fully accounted for. This has been corrected.

>> Changes to data management that could impact results <<
1.   None.

>> Changes that do not impact results <<
1.   Fixed and issue where you can't format axis titles if Graph Results window
     is pulled out.



*** Changes for Version Date 2020.08.27 ***

>> Changes to computation logic that could impact results <<
1.   In some rare instances, valves using Cv/Xt for loss could find an incorrect solution
     for non-choked flow. This has been corrected.
2.   Several issues with Passive-Passive type Relief Valves were corrected. Namely, the
     results when choked flow existed out of the valve could be somewhat incorrect. Most
     severely, inline balanced type passive-passive relief valves incorrectly showed an
     inline loss in some situations, and exit balanced type passive-passive relief valves
     would incorrectly show a fully open or fully closed solution.

>> Changes to data management that could impact results <<
1.   Fixed a potential problem opening older model with output which do not have the
     newer .out file format.
2.   GSC: The roughness value was not being transferred to the pipe when it was used as
     the variable as the results were being transferred as initial conditions.

>> Changes that do not impact results <<
1.   Fixed problem that retained the output when a child scenario was created with no
     output from the Quick Access Panel.
2.   Fixed a 'lag' when dropping a junction on the Workspace.
3.   Fixed an issue where the common pipe was not being saved for a profile graph
     plotting groups.
4.   Excel Export can now utilize XLSM Workbooks.
5.   Excel Export would sometimes give an error message if an export was attempted with
     no Export Items applied, and then retried with exports applied. This has been fixed.
6.   During a batch run, if Excel Export had no Export Items or no applied Export Items,
     the export could give an error message. This has been fixed.
7.   The Visual Report Auto Color Mapping in certain cases would generate erroneous data
     ranges if the "Generate" button was clicked more than once. This has been fixed.
8.   Editing data for a Component in a database would always return a message saying
     that "The junction cannot be updated because it is lacking required data." This has
     been fixed.
9.   Fixed an issue that could cause 'Select Shortest Path' to fail after renumbering
     objects.
10.  Fixed an issue that could cause 'Select Shortest Path' to select a non-shortest
     pipe when multiple pipes shared the same start and end node, in special cases.
11.  Fixed an issue that would cause Tee/Wye Auto-Arrangement to fail when using the
     'Jump' feature.
