What's New

Added SLS quasi-permanent concrete stress check (\(\sigma_c \leq 0.45 \cdot f_{ck}\)) per EC2 7.2(3), with support for characteristic, frequent, and quasi-permanent limit states
Envelope combinations now automatically regenerate when basic loads, \(\psi\) factors, or security class change: no manual regeneration needed
Moment arrows now overlay on the section preview, showing direction and relative magnitude of applied moments
Bending check detail popup now displays \(N_{Ed}\), \(M_{Ed}\), and \(M_{Rd}\) values
Added Bottom layers control to multi-layer quick pattern
Eurocode 2 (2023) is now available for selection in the toolbar (Preview)

Improvements

Selecting or deselecting basic loads is now significantly faster and no longer triggers unnecessary chart updates
Security class selector moved to the Load Combinations tab for easier access
\(\cot\theta\) setting moved to the Shear Reinforcement view where it belongs
General improvements to design check recalculation responsiveness

Fixed the Results tab remaining hidden when only auto-generated envelope combinations were present
Fixed formulas not rendering for checks involving moment units (e.g., bending, torsion)
Fixed uncracked SLS check incorrectly appearing as failed instead of passed
Fixed crash when submitting feedback in the feedback dialog
Fixed issue with adding bars in multi-layer mode in quick patterns
