Verified 48m ago## 6.6.6
### New
* **Download Queue** — Queue multiple games from the Store with up to 3 parallel downloads, configurable in Settings. The Downloads tab now shows queued, active, completed, and failed downloads with live progress, Pause/Resume, Retry, Remove, and persistent auto-resume after restart.
* **Offline Store catalog** — A full store catalog now ships with SteaMidra, so the Store and search work instantly even without an internet connection.
* **Faster app-info lookups** — SteamCMD's JSON mirror is now the primary source, with Steam CM as a fallback. Download modals no longer block on Steam login.
* **Better older-version support** — Downgraded Build IDs and manifest IDs are now written into Steam's ACF and persistently retried if Steam is still using the file.
### Fixed
* Fixed game list updates failing when Valve rejects the bundled Steam Web API key by falling back to GitHub mirrors.
* Fixed Goldberg fixes failing when game files are locked or the game is still running.
* Fixed Linux archive extraction creating flat files with Windows-style backslashes instead of proper folders.
* Fixed DDMod downloads failing when the selected folder name contains colons.
* Fixed W
