Weather widget enhancements
- Support multiple weather measures (temp/condition, wind chill, wind speed/direction)
- Cycle between specified measures automatically
- Display Forecast Day and Forecast Hour with pixels stacked on each edge
Additional hot keys
- Alt-N: force next app without waiting for time slice to expire
- Alt-F: Freeze app switching
- Alt-U Unfreeze app switching
Config File Selection
- Use --config-file arg to override env var CONFIG_FILE
- Git-ignore config-local*.yaml, to support multiple custom config files

Systemd Service Refactoring
- The app now runs as a user service instead of a system service
- systemctl --user start|stop|status fwledmonitor #NB: no sudo
- Service config is now at ~/.config/systemd/user/fwledmonitor.service
- Old service config at /etc/systemd/system/fwledmonitor.service is deleted by the installation script
Equalizer Plugin
- Displays equalizer visualization of default audio source
- Package dependencies were updated
- Python dependencies were updated

Major Refactoring:
- Modularized codebase with led_mon/ package structure
- Better code organization and maintainability
- Proper Python module hierarchy
NixOS Package Fixes:
- Fixed installation paths for modularized structure
- Added missing dependencies: python-dotenv, requests
- All runtime files now properly co-located
- time_weather_plugin fully functional with lazy-loaded iplocate
New Features:
- Time and weather display plugins
- Support for config-local.yaml for user customization
- Enhanced .env file support for API keys
- Improved plugin system with better error handling
Dependency Updates:
- Downgraded numpy for PyInstaller compatibility
- Better handling of optional dependencies
Bug Fixes:
- Fixed 'invalid argument: -cf' error
- Lazy-loading of iplocate import (graceful degradation)
- Better error handling in plugin loading

Robustness Fixes:
- Fixed brightness scaling to properly use max_brightness from sysfs backlight devices
- Added clamping of brightness values to valid byte range [0, 255] to prevent overflow errors
- Added safe byte conversion in LED drawing to prevent invalid values being sent to hardware
- Clamped CPU percentage values to [0.0, 1.0] range to handle edge cases
Stability Improvements:
- Better handling of brightness calculation edge cases
- More robust LED matrix value validation before hardware transmission

Major Features:
- Merged latest upstream changes from MidnightJava/led-matrix
- Complete plugin system with temperature and fan monitoring
- Snapshot display functionality with JSON file support
- Dual keyboard backend support (evdev + pynput)
Upstream Integration:
- Enhanced keyboard shortcut handling (Alt+I)
- Multi-panel snapshot display with timing controls
- Improved device discovery and communication
- Better plugin path resolution for Nix installations
NixOS Improvements:
- Added pynput dependency for cross-platform compatibility
- Fixed shell.nix with proper LED matrix development environment
- Enhanced flake with complete dependency management
Robustness Enhancements:
- Graceful fallback when evdev unavailable
- Better error handling in plugin loading
- Improved hardware detection and permission handling

Initial NixOS packaging
Complete flake with NixOS module support
Robustness improvements:
- Fixed evdev permission handling
- Graceful degradation when hardware unavailable
- Fixed Python regex deprecation warnings
- Safe device access in main loop
