I do have some ideas. Maybe we could collapse the type of release under a dropdown. Documented here:
https://vanillaframework.io/docs/patterns/navigation#dropdown

To achieve this we would need to upgrade the version of Vanilla used to the latest one. Which would involve changing the header of the site from:
<link rel="stylesheet" href="https://assets.ubuntu.com/v1/vanilla-framework-version-1.8.1.min.css">
to 
<link rel="stylesheet" href="https://assets.ubuntu.com/v1/vanilla-framework-version-4.7.0.min.css"> 

This would result in the site looking like the attachment screenshot.

The code to replicate the attached screenshot:
```
<header id="navigation" class="p-navigation is-dark">
  <div class="p-navigation__row--25-75">
    <div class="p-navigation__banner">
