v0.7.1

• DLL downloads now use mirror — primary source (official ST updater) still uses HTTP. In order to prevent ISP/antivirus tampering that was causing hash mismatches for some users, I switched from the primary to the secondary. This is a cosmetic change, the app already hash compared the two sources.

• Better payload diagnostics — "unknown payload version" is now split into "payload corrupt" (can't decrypt) vs "unsupported payload version" (unrecognized signatures), with actionable guidance

• Option 4 cleans up bad payloads — after repairing DLLs, if the payload cache is corrupt or unrecognized it gets deleted automatically so Steam can download a fresh one on restart

v0.7.0

Morrenus fallback removed

The Morrenus API has been shut down now that SteamTools is back up. All fallback-related functionality has been removed.

If you previously had fallback configured, STFixer will automatically detect it on startup and offer to cleanly revert the patches.

v0.6.0

• Fix diagnostics falsely reporting Capcom Game Save Fix as patched after running certain other options

• Reorder diagnostics to match order in menu

• Options 1, 2, and 4 now offer to patch SteamTools.exe after success as they also patch the file that SteamTools.exe reverts

• New Option 3: dedicated "Patch SteamTools App" (only shown when patches are active and SteamTools.exe is unpatched)

v0.5.9

• Fix manifest request spam (cache, rate limiting, daily limit dialog). Issues that would cause excessive usage in some edge cases have been solved
• Add guidance to SteamTools EXE patching prompt to solve for skill issues
• Kill SteamTools.exe automatically before patching or restoring it

v0.5.7

• Renamed to STFixer to avoid user confusion. Long overdue.

v0.5.6

• Better handling for bad x_input/dwm DLLs, better repair flow

v0.5.5

• Steam version check in diagnostics
• API key validation on startup/ISP issue detection
• Version number added to title bar

v0.5.4

Fix CLR FailFast crash on CPUs with Intel CET (Control-flow Enforcement Technology) shadow stacks.

v0.5.3

Improved DLL repair detection logic, again

v0.5.2

Edge case handling for fallback patch
