What's New

• Added support for designing slab strips with per-metre reinforcement and slab detailing checks.
• Added a moment-curvature diagram to the analysis charts.

Improvements

• Calculation popups now show step-by-step derivations for more section properties and detailing checks.
• Reinforcement placed outside the cross-section is now flagged as you edit.
• Interaction diagrams now hide serviceability load cases by default, with a toggle to show them.
• The app now remembers its window size, position, and sidebar state between sessions.
• Improved the appearance of the Eurocode reference tables and figures in the material info popups: they now display at consistent, balanced sizes within cleaner cards.
• Minor UI improvements.

Bug Fixes

• Fixed an issue where biaxial bending utilisation could be computed incorrectly; it is now solved along the load direction.
• Fixed an issue where a cracked section under biaxial bending could wrongly report an uncracked pass for crack width; it now warns instead.
• Fixed an issue where the strain and force diagram was drawn in the wrong orientation for hogging moments.
• General stability improvements.
