Downloads

See the assets below to download installers for this version.

Platform	Asset suffix
macOS Apple Silicon (M1/M2/M3/M4)	*_macos-apple-silicon.dmg
macOS Intel	*_macos-intel.dmg
Windows x64	*_windows-x64.msi / *-setup.exe / portable *.exe
Windows x86 (32-bit)	*_windows-x86.msi / *-setup.exe / portable *.exe
Windows ARM64	*_windows-arm64-setup.exe / portable *.exe
Linux	*_linux-x64.AppImage / .deb / .rpm

Windows portable .exe: run directly without installing. Still requires
the WebView2 Runtime (preinstalled on most Windows 10/11 machines).

On Apple Silicon, use the apple-silicon DMG. The Intel build runs under
Rosetta and may show a soon-unsupported warning.
