*** Changes for Version Date 2011.04.15 ***

Initial release



*** Changes for Version Date 2011.08.11 ***

>> Changes to computation logic that could impact results <<
1.   The maximum stagnation and static pressure drop pressure constraints were
     incorrectly identifying constraint violations. This was fixed.

>> Changes to data management that could impact results <<
1.   When using a junction that has a larger flow area than the pipe itself at an exit
     to a pressure (such as a relief valve) then the model may not converge if sonic 
     choking exists. This was fixed.
2.   When a scenario other than the current scenario and then the Scenario Manager is
     closed without loading the current scenario the number of pipe and junction 
     objects from the parent was being reset to what ever the parent of the saved
     scenario was. This caused the data flow from the parent of the current scenario
     was corrupted and some objects which were deleted in the current scenario but exist 
     in its parent were being shown. This was fixed.
3.   When a scenario was promoted it would acquire the GSC Type of the new parent.
     This would cause problems graphing if the new parent was used a different state.
     This was fixed so that the original Analysis Type was retained.
4.   Updated the arrow4.dat file with minor corrections to PVC, Ductile Iron and Copper
     Pipe. See notes in the file for specific details.

>> Changes that do not impact results <<
1.   Fixed problem graphing physical properties in the pipe material database.
