AppImage

Auto Updating

AppImage has a very smart and economical way of updating. It calculates the delta between the new appimage and the older one and will only download the changes between their versions. So essentially, the user theoretically ends up downloading ~10%-15% instead of a a new appimage each time. This is done via an AppImage application.

via Command Line Interface

appimageupdate

via GUI

appimageguiupdate
