* [**Snow Loads (ASCE 7-22)**](https://calcs.com/calculators/loadsSnowASCE7-22) **🇺🇸:** Added snow load calculator to our API

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

* **HSS-HSS Moment Connection - Member-End Distance Reductions 🇺🇸 :** Implemented capacity reductions for connections near member ends per AISC 360-22 Section J10 (US). Includes new end distance inputs and updated limit state calculations for web local yielding, crippling, and flange bending.
* **Axial Load Handling (Moment Connections) 🇺🇸 :** Introduced axial load support for WF-to-HSS and HSS-to-HSS moment connections, featuring new axial demand widgets, load tables, and axial-moment interaction checks.
* **Built-Up Tee Support 🇺🇸 :** Added built-up tee section options for WT connections, including new geometry inputs, weld design calculations, and modified dynamic diagrams.
* **HSS Splices 🇺🇸 🇨🇦:** Introduced configurable horizontal and vertical bolt spacing inputs to replace fixed spacing, with real-time updates to capacity calculations and diagrams.
* **HSS Splice 🇨🇦:** Fixed a service load calculation bug where reference IDs incorrectly pointed to US calculator values.
* **Truss Connections 🇨🇦:** Unified weld calculations with base metal sections and standardized the weld design methodology.
* **Column Bracing 🇨🇦:** Added bolted connection support for Canadian column bracing with splice plate section and new validation presets.
* **HSS Truss Logic:** Enhanced connection type evaluation for two-branch members with external loads and three-branch configurations.

### Calcs Builder

* **New Builder Polish:** Added persistent "Add Widget" buttons in each section for ease, improved autocomplete while typing formulas, and enhanced unit rendering.
* **Sidebar Improvements:** Implemented bulk show/hide visibility controls for easier navigation, added widget icons for identification on widget type
* **Preview Enhancements:** Calculator previews now clearly display selected building standards, unit systems, and presets with a re-clickable preview button.
* **Equation Input Highlighting:** Added character-level change highlighting in equation inputs to pinpoint specific modifications within larger text blocks.
* **Table Column Editor:** Reintroduced the `referenceId` field to table columns for consistency with legacy builder functionality.

### Platform Improvements

* **Details Library 🇺🇸 🇨🇦:** Added multi-country content support with a selection toggle to differentiate US/CA content.
