Release Notes – Codebase Refactor & Modularization

• Major project restructuring
  • Reorganized libraries and source files into a clearer, more modular directory structure.
  • Moved, renamed, or removed numerous files to reduce duplication and improve maintainability.
• Legacy code cleanup
  • Removed deprecated and unused code from lib-lightset, lib-network, lib-properties, and older display components.
  • Eliminated redundant parameter and platform-specific files no longer in use.
• Centralized common functionality
  • Migrated shared network, properties, and parameter code into a unified common directory.
  • Added new utility headers and source files for reusable functionality.
• JSON-based configuration support
  • Added new JSON configuration and parameter files.
  • Introduced JSON helper utilities and parameter classes to standardize configuration handling and prepare for future extensibility.
• DMX, RDM, and pixel refactor
  • Refactored DMX, RDM device handling, and pixel-related libraries for clearer structure and better separation of responsibilities.
  • Unified RDM device information handling.
• Build system updates
  • Updated Makefiles, build scripts, and compile_commands.json to reflect the new project structure.
  • Improved GD32 platform support and hardware abstraction organization.
• Network stack reorganization
  • Flattened lib-network source layout by moving files from subdirectories into a simpler structure.
  • Improved clarity of EMAC and Linux network interface implementations (no functional changes).
• Debug macro consistency
  • Replaced DEBUG_ENTRY / DEBUG_EXIT macros with function-style DEBUG_ENTRY() / DEBUG_EXIT() across the codebase for consistency and readability.
• Overall impact
  • Significantly improved modularity, readability, and long-term maintainability.
  • Laid groundwork for future feature expansion and more robust JSON-based configuration across modules.
