## What's New & Improvements

### **Engineering Calculators:**

* [**Masonry Shear Wall (LRFD)**](https://calcs.com/calculators/masonryShearWallLRFD) **🇺🇸:** Introduced axial capacity calculations, optional horizontal reinforcement design, and a new Seismic Design Category selector with TMS 402-22 limit validations.
* [**Wind Loads (ASCE 7-22)**](https://calcs.com/calculators/loadsWindCnCASCE7-22) **🇺🇸:** Enhanced with comprehensive monoslope overhang calculations for both MWFRS and Components & Cladding.
* [**Snow Loads (ASCE 7-16/22)**](https://calcs.com/calculators/loadsSnowASCE7-22) **🇺🇸:** Improved transparency for unbalanced gable-roof loads by providing explicit windward and leeward outputs.
* **US Seismic SFRS 🇺🇸:** Added "Steel ordinary concentrically braced frames" (OCBF) to the system library with dynamic height limit footnotes.
* [**Wood Beam (NDS 2024)**](https://calcs.com/calculators/timberBeamASD) **🇺🇸:** Released new ASD and LRFD templates fully updated to NDS 2024 and IBC 2024 standards.
* [**Concrete Beam/Column/Slab**](https://calcs.com/calculators/concreteBeamRectangularUSAACI318-19) **🇺🇸:** Updated all templates for IBC 2024 compliance with refreshed technical references.
* [**Pier Footing**](https://calcs.com/calculators/foundationsPierFootingUSA) **🇺🇸:** Added a "Consider Self-Weight for Uplift" toggle to include foundation weight in resistance checks per ICC and ACI 318-19.
* **Timber Species 🇺🇸:** Fixed $F_{bx}$ values for 2.1E-3100Fb grade, correcting the value from 2800 to 3100 psi.

### [Atlas Tube Connection Hub](https://www.atlastube.com/hss-connections-hub/)

* [**HSS-to-HSS Shear**](https://www.atlastube.com/hss-connections-hub/) **🇺🇸:** Added "Extended Configuration" supporting single plates, coped beams, exterior plates, and through-bolt moment calculations with new widgets for bolt configuration and moment calculations.
* [**WF-to-HSS Shear**](https://www.atlastube.com/hss-connections-hub/) **🇺🇸:** Fixed bearing length calculations to properly account for beam setback.
* [**HSS Splices**](https://www.atlastube.com/hss-connections-hub/) **🇺🇸 🇨🇦:** Converted bolt spacing from computed values to adjustable user inputs with integrated validation for end-plate configurations. Added shear load inputs expanding from P,M to P,V,M load vectors with updated demand calculations
* [**WF-to-HSS Moment**](https://www.atlastube.com/hss-connections-hub/) **🇺🇸 🇨🇦:** Refined dynamic diagrams with enhanced weld symbols
* [**Column Brace**](https://www.atlastube.com/hss-connections-hub/) **🇺🇸 🇨🇦:** Added AISC 360-22 J10.5 web compression buckling checks for mirrored connections. Enhanced interaction checks considering eccentricity-induced bending moments and improved buckling calculations for bolted splice-to-gusset connections
* [**HSS Beam-to-HSS Moment**](https://www.atlastube.com/hss-connections-hub/) **🇨🇦:** Corrected shear area logic to account for both HSS section walls, effectively doubling the calculated capacity.

### [Calcs Builder](https://calcs.com/builder)

* **Sticky Sidebar Visibility:** Your widget visibility preferences (hidden vs. shown) are now saved via local storage, so they persist when you return to a template.
* **Widget Commenting:** Comment input boxes now automatically focus upon opening, allowing for immediate typing without an extra click.
* **PDF Export Branding:** All PDFs exported from custom calculators now feature a "Custom Calculator created on Calcs.com" banner.
* **Admin Feature Tiers:** Organization admins can now toggle between "Standard" and "Early Access" feature tiers to test new Builder functionality.

### **Platform Improvements:**

* **Navigation Sidebar:** Added "Collapse All" and "Expand All" functionality for the widget tree to manage large templates more easily.
* **Color Coding Cleanup:** Removed green color overlaps between preset layers and test results to ensure "Passing" status is visually distinct.
* **Status Page:** All system links updated to point to the new [status.calcs.com](https://status.calcs.com) domain.
