Christian Schaller has a lengthy update on the progress of Fedora 21. He looks at a number of different features, including Wayland, GNOME 3.14, software installation (dnf and "Software"), and more. "This also highlights one of the advantages of the new Fedora product model where we have one clear desktop product we are targeting, that we can define operating system standards for things like application metadata and apply them to the system as a whole. So for Fedora 22 we expect to make appdata metadata a mandatory part of the application packaging for Fedora, ensuring that any desktop application packaged for Fedora is easily discover able by our users. In the old ‘bucket of parts’ model these things would in practice not happen as there was no clear target that everyone was expected to aim for."
