The changes seem sensible, but those changelog entries are a bit terse.

Remember that the category, the thing inside the brackets, room_preview will be gone once we generate the changelog. So the entry will look like:

• Add heroes for known rooms
• Compute display name

And people will be left wondering what this is about.

Oh, I didn't know that! Yeah, I'll tweak the commit messages then 😅 .
