SteaMidra v6.4.7
What's new:
- Added a brand-new native Python Steam CDN downloader for Linux. Downloads now come directly from Steam's CDN using parallel chunk downloads, manifest parsing, AES decryption, and automatic decompression—no .NET runtime required. DepotDownloaderMod remains available as a fallback if needed.
- Native Linux downloads now support incremental updates. Existing game files are verified first, so only changed chunks are downloaded after a manifest update instead of re-downloading the entire game.
- Added a download concurrency setting to Download Settings. Choose anywhere from 8 to 64 concurrent chunk downloads, and the same setting is also applied to DepotDownloaderMod.
- Improved CDN server selection with smarter server weighting, retry rotation, exponential backoff, and HTTP connection reuse for more reliable and consistent download performance.
- Fixed Linux depot OS filtering. Downloads now correctly exclude Windows-only and macOS-only depots, matching DepotDownloaderMod's operating system filtering.
- Every ACF file written by SteaMidra is now marked read-only immediately, preventing Steam from reverting installed games back to the Update state.
- Restart Steam now displays live progress directly in the Web UI on Windows, with improved error reporting on both Windows and Linux.
- Self-updating is now much more reliable on slow connections. Added proper download and installer timeouts throughout the entire update pipeline.
- Fixed Linux downloads after the download bridge signature changed. The Web UI and backend now use matching arguments again.
- Store status cache now has automatic eviction, preventing memory usage from growing indefinitely while browsing games.
Linux improvements
- Steam launched through SteaMidra no longer inherits AppImage environment variables, fixing silent launch failures on Fedora, CachyOS, and similar distributions.
- Fixed the Steam Native older-version downloader attempting Windows-only operations on Linux. The native path is now correctly limited to Windows, while the DepotDownloaderMod fallback starts downloads with the proper depot key data.
- SteamAutoCrack now works correctly from AppImages by writing temporary configuration files to the SteaMidra data directory and injecting API keys without triggering
Errno 30errors.
Windows improvements
- Restored proper window resizing by enabling the required native Windows resize frame for the frameless window.
- DDMod downloads that encounter the Windows socket handle leak (
10038) now automatically retry withoutCREATE_NO_WINDOW, greatly improving download reliability.
