- Added Steam launch/restart, startup registration, tray controls, logs, and single-instance handling.
- Preserved Windows Velopack installation and automatic updates.

Safety improvements
- Existing files can be backed up before replacement.

Upgrade notes
Windows users should use TOST-win-Setup.exe. Portable users should extract the complete new ZIP into a fresh folder instead of replacing only the executable.
Linux support is new in this release. Available packages include the portable archive, AppImage, and Arch package.
