Coming about five weeks after the GNOME 40.2 release, GNOME 40.3 is here with an updated GNOME Software app that now automatically installs application updates depending on the type of application and user configuration. It also includes apps from disabled repositories in the search results of the Activities Overview, an improved Updates tab, as well as better support for PackageKit apps.
The Evince document viewer has been updated as well to display “None” when the creation or modification date is missing from a document, as well as to enable the Odd Pages Left option only when the dual page feature is active. Also, the GNOME Boxes app received improvements to the run-in-background functionality for non-Flatpak builds.
