Thoughts on combining these notes into one? They both come from a single code change. Otherwise LGTM.

[amyleadem]

@mejiaj That's a good question. I could really go either way on combining them. I lean towards keeping them separate for a couple of reasons:

1. Only one item is a breaking change and I like being able to focus the breaking entry on related user action
2. The changes feel distinct to me and it feels easier to scan if they are separate entries

LGTM! I'm indecisive about splitting into two or combining into one changelog. Maybe we should establish a pattern for if each changelog item is per change or per PR.

@mahoneycm @mejiaj
Our changelog template README currently recommends breaking up features into multiple data items:

If a single release item accomplished multiple tasks, break the tasks up into separate data items. The goal is to itemize and highlight user benefits and actions required.

I believe this was born out of some of the earlier discussions about changelogs. Happy to discuss this more if you are inclined to change the standard. We also could refine the README to be more clear if it feels muddled.

@amyleadem thanks for the feedback. Approving since there doesn't be a strong reason to combine them.

I support Amy's reasoning for a per-change approach to changelogs. A single PR may have multiple changelog-worthy items.
