AppImageUpdate

Uses update information embedded in the AppImage itself, eliminating the need for central repositories and allowing upstream developers to distribute updates directly, as outlined in the philosophy section.

Downloads only the changed portions of applications via delta updates, reducing bandwidth usage and making updates fast, a key feature highlighted in the README.

Provides both a GUI application and a command-line tool (appimageupdatetool), offering choice for different user preferences and automation needs, as described in the components section.

Includes GPG signature validation to ensure update integrity and prevent tampering, a feature explicitly mentioned in the key features for enhanced security.

Designed to support additional transport mechanisms like peer-to-peer updates, allowing for evolution beyond current capabilities, as noted in the objectives.
