TrainerBridge 1.0.1

TrainerBridge 1.0.1

TrainerBridge 1.0.1 is a maintenance and hardening release focused on reliability, diagnostics, packaging, and edge cases found during extensive post-release testing.

Highlights

• Redesigned Live Log with timestamps and clear OK, INFO, WARNING, and ERROR levels.
• Added Copy all, Save as..., and Clear actions to the Live Log.
• Normal application use no longer creates persistent log files automatically.
• All TrainerBridge-owned windows now use defined, non-resizable sizes.
• Added per-user single-instance protection.
• Improved launch, cancellation, and game/trainer lifecycle handling.
• Added additional security hardening for Steam metadata and exported scripts.
• Improved AppImage build reproducibility and release privacy checks.

Fixes and reliability improvements

• Fixed a possible Qt thread shutdown issue when closing TrainerBridge during an active launch sequence.
• Steam AppIDs are now matched exactly instead of by substring.
• Exported native/Snap launch scripts now verify the actual Windows game executable and stable PID before starting the trainer.
• Protontricks discovery and read-only catalog queries now use bounded timeouts without freezing the GUI.
• Fixed a session lifecycle issue where closing the game before its TrainerBridge-launched trainer could prevent another game from being launched.
• Trainers started by TrainerBridge are now cleanly stopped when their associated game exits.
• Improved cancellation handling while keeping the game running.
• Runtime and build version metadata now comes from one APP_VERSION source.

Security hardening

• Steam manifest AppIDs are restricted to ASCII digits before they can influence trainer, backup, Proton-prefix, launch, or export paths.
• Invalid or unsafe Steam installdir values no longer produce an Open Game Folder target.
• Exported Bash scripts no longer interpolate the Steam game name into a comment line, closing a newline-based shell-injection edge case while keeping GAME_NAME safely shell-quoted.
• Release checks prevent developer-specific absolute home paths from leaking into TrainerBridge-owned packaged text files.

Build and packaging

• Updated to the maintained AppImage/appimagetool project.
• Pinned appimagetool to version 1.9.1 for reproducible builds.
• Fixed a pipefail/SIGPIPE issue that could prematurely stop the AppImage build.
• Improved build-time privacy checks while correctly ignoring upstream build paths embedded in third-party binaries such as Qt.
• Expanded automated regression coverage to 96 tests before release.

Downloads

• TrainerBridge-1.0.1-x86_64.AppImage — recommended.
• TrainerBridge-1.0.1-x86_64.tar.xz — portable directory version.
