📝 Release Notes — Horizon DE v0.4.21-alpha
Welcome to the release notes for Horizon DE version 0.4.21! This development cycle has focused primarily on a deep migration towards dynamic customization and system-wide theme support (Theming).
🖥️ Experience Horizon
Horizon is not just a toolkit — it powers an entire desktop environment.
The best way to experience it today is through Austral OS, where Horizon drives the full system UI.
🚀 Key Highlights & Features
🎨 Extensible Customization & Global Theme Support
The system's visual management has been redesigned through the global integration of ThemeManager alongside major improvements to its flexibility:
- Color Scheme Selection UI: A new user interface implemented in Appearance preferences (
AppearanceView) for direct color scheme selection. - Smart Opacity & Transparency: Implemented support for adjustable UI element opacities, linear gradient menu backgrounds with configurable bottom opacity, and alpha transparency support for panel backgrounds.
⚙️ System Monitoring & Resilience
- Critical Session Services: Implementation of robust monitoring and automatic restart logic for critical session services, substantially improving fault tolerance.
- Dynamic Compositor Selection: Added a compositor selection user interface to preferences and updated session startup scripts to support dynamic switching.
