Description of problem: Not really a major issue (yet), but F16 at the least should have a placeholder text here rather than having F15 release notes. I'm filing this as a tracker for F16 Release Notes progress.
This is not a bug, it is a feature. Release notes are not available until beta, and then they are only a single language. However, the composers want something to give them a feel for the size, so alpha always has the previous release's notes.
