Not sure if you noticed, but we actually parse the `heading` for content that should be put into the subheading.

In this case though, it's not very telling what that date represents to please add in `Release Date:`

```javascript
heading: item.name + '( Release Date:' + release_date(item) + ')',
```

//cc @russellholt @jagtalon -- is there a nicer way of doing this? Can we explicitly set the sub-heading?
