6.6.5

New

• Automatic Build ID downloads — Download Older Version can now select a Build ID from SteamDB and automatically retrieve the matching depot manifests through DepotBox. Manual manifest selection remains available.
• Provider credits — Ryuu, DepotBox, and Hubcap now have dedicated credits and community-server links in the download UI and Settings.
• Crack notifications — Download dialogs now show available crack information and can guide you to the required Build ID. Installed games can also detect mismatched crack builds and offer to apply the correct crack.
• SteamCMD app-info fallback — Added a reliable SteamCMD app-info mirror for faster and more reliable game metadata lookups.
• Downgrade tracking — Older-version installs now update Steam's ACF with the selected Build ID and manifests, with automatic retry if the ACF is unavailable or locked.
• MidraEveryDay — OurEveryday has been renamed to MidraEveryDay.
