• FIXED – Custom weather rendering in Advanced Mode. Rebuilt several internal hooks responsible for multi-layer atmospheric rendering, improving fidelity and proper synchronization between volumetric clouds, and lighting.
• FIXED – Required description field preventing preset saving and edit function. Adjusted UI rules to allow preset persistence without unnecessary conditions.
• FIXED – UI validation preventing the Save button from enabling. Resolved conditional flag errors that interfered with save-state logic.
• FIXED – GetLocalSettingsRead() not reading local settings.json. Repaired the file read routine, corrected its directory resolution, and improved JSON parsing, ensuring user preferences load correctly at startup.
• FIXED – Spelling correction of “Enviro” in the save dialog box. Corrected text label.
• ADDED – Startup Log System for application process verification. Integrated a multi-stage logging pipeline that records initialization events, module load order, environment checks, and error flags.
• ADDED – Simulator Runtime Validation. Implemented a detection function to confirm whether Microsoft Flight Simulator is actively running. This ensures correct sequencing, prevents null-reference operations, and delivers safer startup behavior.
