Release 4.0 - May 14, 2026

Release notes for Xylem Solver version 4.0

ENHANCEMENTS

Curve Display and UI Improvements in Selection Details

  • We’ve updated how pump performance curves are displayed in Solver to make charts easier to read and interpret – especially when working with multiple speeds or complex selections. The updated design reduces visual clutter by simplifying labels, standardizing fonts, and improving spacing, while keeping all underlying data and functionality the same.

    • Label Simplification: Efficiency, power, and NPSH labels have been removed from curves to reduce overlapping text and improve readability.

    • Cleaner Axes & Layout: Axis labels are now displayed as symbols inside the graph, with a cleaner grid layout to reduce visual clutter.

    • Typography & UI Alignment: Fonts and chart styling have been standardized to provide a cleaner and more consistent Solver user experience.

    • Improved Multiple Speed & Curve Views: Multiple speed and curve displays are now easier to read, with reduced overlap and improved curve visibility.

    • Selected Curve View Enhancement: Only relevant speed and diameter information is displayed in selected curve view, while unnecessary labels are removed to improve clarity.
