Both can indeed do it. > Like how would you get a diff between two release builds... > > [1] https://wiki.yoctoproject.org/wiki/Meta-swupd With meta-swupd, set SWUPD_DELTAPACK_VERSIONS to generate binary diffs against certain older releases. In addition, a single archive gets created with just the right content for updating from the older releases to the current one (= better compression, less GET requests). > [2] https://github.com/advancedtelematic/meta-updater That's basically OSTree.
