Following up from #16755 (comment).

I still think we should not do this. Our current format groups all the changes that are related to the same feature under one bullet point.

IMO, I think we should still continue to follow the following format:

# Release Version

## Breaking Changes

### Feature Name
- Change 1
- Change 2
- Change 3

## Change Logs

### Feature Name
- Change 1
- Change 2
- Change 3

Fine by me, how about now?

@Piedone I would also either move the addition External Authentication feature to New Features section, or add a reference to the new External Authentication feature in the New Features section.

I added it at the bottom. However, now the original section above doesn't make sense. So, I moved that under the Users feature, which is the one that actually changed.
