## [3.0.0] - 2026-07-15

### ✨ Features
- **Generic Host DI**: Integrated `Microsoft.Extensions.Hosting` to manage dependency injection and app lifecycle.
- **Thumbnail Caching**: High-performance thread-safe `MemoryCache` that prefetches thumbnails in the background, minimizing UI flicker.
- **Dynamic Categories**: Scraping categories dynamically from 4kwallpapers.com with robust hardcoded fallback.
- **Wallpaper Search**: Dynamic search with full UI support and infinite scrolling pagination.
- **Favorites & Bookmarks**: Save favorite wallpapers locally and browse them through a dedicated `⭐ Favorites` category.
- **Tray Menu Toggle**: Added a checkable "Auto-Change Enabled" option to the system tray context menu to pause and resume the scheduler.

### 🐛 Bug Fixes & Refactoring
- **Structured Logging**: Replaced silent catch blocks with `Serilog` file logging for easier troubleshooting.
- **Async Cancellations**: Implemented `CancellationToken` across all scraper, service, and view model async calls.
- **Thread Safety**: Secured settings serialization using a thread-safe static lock block.
- **Removed GC Anti-Patterns**: Removed outdated MemoryOptimizer to let the .NET GC manage RAM natively.
