    • Data can be compared between multiple scenarios to show changes made
    • Multi-level undo and redo on the Workspace
    • Cross-plotting of Pump vs. System curves across multiple operating scenarios
    • All Summary Output parameters can now be displayed on the Visual Report
  • General Interface: Improved intelligence on when a model needs to be saved to preserve the output as well as improved model loading speed and language refresh speed
  • Workspace: Double-click on a junction on the Toolbox to add multiple to the Workspace (similar to pipes). Junction icons automatically rotate to align with pipes. Magnifier tool to quickly view objects on the Workspace. 
  • Pipes: Heat tracing now allows the entry of power/length and number of turns. Convert intermediate pipe elevations to new pipes and branch junctions
  • Junctions: More intelligent Tee/Wye junction during input and Workspace movements. Built-in K values for bends with r/D between 0.5 and 1
  • Output: Notes can be added to cells in the Output tables. Output Control parameters can be filtered by typing part of the parameter name. The thermal conductivity used in the heat transfer calculations is now displayed
  • Global Edit: A pipe or junction can be selected as the base data to apply to other pipes or junctions. Notes can be globally edited on junctions
  • Other: Ability to import custom Fittings & Losses from a comma-separated file. Design Alerts can be saved to and loaded from a comma-separated file. New Diagnostics window to help identify special features or options being used in the scenario
