Comment 1 for bug 324831

Why? nUbuntu refers to its series that way, but I haven't seen any other distributions that do. (Ubuntu certainly doesn't, for example.)

Meanwhile, the (approved!) spec <https://dev.launchpad.net/RegistrySimplifications> says: "In the Web UI, .codename should be used before a series is released, and .version afterward (though the codename should still be mentioned on the Overview page). This should be done using a generated property, which should be called .displayname for compatibility with other object types."
