You may have heard us mention formats and format bumps from time to time. To put it simply, formats are how swupd views the OS so it knows how to handle all the bundles and changes to bundles as the OS is updated. When the way those bundles are handled is changed, we bump the format version number and update swupd to ensure it can handle the new format. If we do it right, the users shouldn’t see any impact. swupd updates should work forward across format bumps, but are not guaranteed to work if you try to back rev to a particular version of Clear Linux with a previous format.
