# Version 3.7.6 Update Summary

**Release Date**: October 25, 2025  
**Previous Version**: 3.7.5  
**New Version**: 3.7.6

## 🎨 Main Enhancement: Unicode Bold Search Highlighting

### Feature Overview
The TMX Editor now uses **Unicode Mathematical Bold characters** to highlight search terms directly in the Treeview grid, providing true bold rendering without markers or special characters.

### Visual Example
When searching for "concrete":
- **Before**: T-shaped «concrete» base (with guillemet markers)
- **After**: T-shaped **𝐜𝐨𝐧𝐜𝐫𝐞𝐭𝐞** base (true Unicode bold)

### Technical Implementation
- **Character Ranges Used**:
  - Uppercase A-Z: U+1D400 to U+1D419 (𝐀-𝐙)
  - Lowercase a-z: U+1D41A to U+1D433 (𝐚-𝐳)
  - Digits 0-9: U+1D7CE to U+1D7D7 (𝟎-𝟗)

- **New Methods**:
  - `highlight_search_term_in_text()` - Main highlighting logic
  - `_to_unicode_bold()` - Character conversion to Unicode bold

### Dual Highlighting System
1. **Row-level**: Light yellow background (#fffacd) for matching rows
2. **Term-level**: Unicode bold characters for precise word highlighting
