<https://myapps.developer.ubuntu.com/exhibits/> includes fields to specify which Ubuntu versions an exhibit should be shown for.

Unfortunately, this data is not included in <https://software-center.ubuntu.com/api/2.0/exhibits/en/>.

As a result, exhibits are published for every Ubuntu version, even Ubuntu versions where the exhibited software is not available.

This will be more important once there are multiple Ubuntu versions for which USC shows exhibits (11.10 and 12.04). But it's important now, because I publish exhibits in 11.04 -- to test that they work at all -- before publishing them in 11.10.
