Version 1.2.2 built on 2026-03-13

Fixes

• WriteOverlay: Moving a newly created file into a subfolder of the read-only source failed.
• WriteOverlay: Broken symbolic links were not correctly removed from the overlay folder.
• Avoid network requests for --version and --oss-attributions-short.
• Automatically create parent paths to log file specified with --log-file if they do not exist.
• Make format detection more robust against empty or small files and without sqlcipher3 installed.

AppImages

The AppImages can be downloaded, made executable with chmod u+x *.AppImage, and executed directly to start ratarmount.

There are also usability helpers for AppImages such as AppImageLauncher and AM.

If the AppImage is too slow to start up or to reduce memory overhead for the AppImage itself, the AppImage can also be manually unpacked and installed:

• Extract with ratarmount-*.AppImage --appimage-extract
• The extracted AppImage can be started by executing squashfs-root/AppRun.
• Rename and move the resulting generic squashfs-root folder wherever you want, e.g., /opt/ratarmount-<version>.
• Add a link to /opt/ratarmount-<version>/AppRun into some folder that is in your PATH variable, e.g., with:
  ln -s /opt/ratarmount-<version>/AppRun ~/.local/bin/ratarmount
