Release v1.0.0 contains the initial release of SnapForks offline. Currently, only Windows binaries are available but other platforms may be added later.
Do not use the archive with the source code that Github automatically provides, instead download the archive named "SnapForks-Offline-Setup.zip" and run the installer inside it.
Update: Windows Security is reporting a false positive for Trojan:Script/Wacatac.B!ml. The executable has been run through VirusTotal with no threats found and was packaged with electron-builder so I do not know what is causing this.
