GOverlay 1.8.9 was released this week, introducing significant improvements to MangoHud integration and OptiScaler compatibility. A key new feature is per-game blacklist support for MangoHud, allowing users to automatically append the "blacklist=" directive to both global and game-specific MangoHud configuration files. This enhances granular control over the overlay's behavior for individual games. The update also unifies the global mode storage structure under "goverlay/gameconfig/global/" to mirror per-game profiles, ensuring consistent configuration management and automatic synchronization with system-wide MangoHud paths. Additionally, the blacklist window user experience was improved, with button modal properties fixed so the window remains open after adding or deleting items. For OptiScaler and bgmod integration, version matching logic was refined by stripping the "stable." prefix from release strings to ensure accurate comparisons.
