Changelog (v1.8.9)

MangoHud & Blacklist Improvements

Per-Game Blacklist Support: Automatically append the blacklist= directive to both global (~/.config/MangoHud/MangoHud.conf) and per-game (~/.config/goverlay/<game>/MangoHud.conf) configuration files.
Global Profile Parity: Unified global mode storage structure under goverlay/gameconfig/global/ to mirror per-game profiles, while maintaining automatic synchronization with system-wide MangoHud configuration paths.
Blacklist Window UX: Fixed button modal properties in blacklistunit so the window remains open after adding (+) or deleting items.

Version String Comparison: Fixed version matching by stripping the stable. prefix when comparing OptiScaler releases.
Fakenvapi Fixes: Corrected an off-by-one key length check for fakenvapiversion and resolved a configuration key typo in bgmod.
Silent Saving & UI Sync: Added silent saving modes to prevent UI desynchronization

Non-Steam Games Config: Fixed path resolution for nonsteam_folders.txt using TConfigManager.GetGoverlayFolder to ensure proper Flatpak sandbox support.

Changelog Deadlock: Resolved a menu option freeze and curl I/O pipe deadlock when fetching and parsing release notes.
