Install a snapshot

Newt does not have versioned releases yet. The download page provides development snapshots built from a specific source commit.

Caution

Snapshots track active development. Features, settings, and configuration formats may change between builds.

macOS

Download the DMG for your Mac’s architecture, open it, and move Newt into Applications.

Windows

Download and run the MSI package matching your system architecture.

Newt requires the Microsoft Edge WebView2 Runtime. The MSI checks for it but does not download it; if it is missing, install the runtime from the link the installer shows, then run the MSI again.

Note

Per-user and per-machine installations cannot upgrade each other. If you switch scopes, uninstall the old copy first, otherwise both remain installed.

Linux

Choose either the AppImage or a package built for your distribution. Current packaging covers Debian, Ubuntu, Fedora, and Arch Linux on the architectures shown on the download page.

For the AppImage, mark it executable before running it:

chmod +x Newt-*.AppImage

Newt uses the system GTK 3 and WebKitGTK 4.1 libraries. Native distribution packages pull them in as dependencies; the AppImage does not bundle them, so they must be installed on the host (libgtk-3-0 and libwebkit2gtk-4.1-0 on Debian and Ubuntu, gtk3 and webkit2gtk4.1 on Fedora, or gtk3 and webkit2gtk-4.1 on Arch Linux).

Verify a package

Each snapshot records its source commit, and the download page shows each package’s SHA-256 checksum. Compare the downloaded file against it before installing:

Platform	Command
macOS	shasum -a 256 <file>
Linux	sha256sum <file>
Windows (PowerShell)	Get-FileHash <file>
